QUARTERLY REPORT FOR THE PERIOD ENDING 31 MARCH 2016 HIGHLIGHTS OF THE QUARTER
OPERATIONS
-
Significant progress made on the off-market takeover offer for copper producer Aditya Birla Minerals Limited (ABY) with acceptances of 29.8 % received. Subsequent to the end of the quarter (announced 26 April 2016), agreement was reached with ABY’s major shareholder, Hindalco (51%) to irrevocably accept the offer and the board of ABY to recommend acceptance. Pursuant to this, Metals X has agreed to increase its offer ratio to one (1) MLX share for each four and a half (4.5) ABY shares and to pay each acceptor to its offers eight (8c) cents per share. The payment of increased consideration is subject to no superior offer arising before 2 May 2016 and Hindalco receiving Reserve Bank of India (RBI) approval.
-
The Gold Division produced 47,951 ounces at a cash cost of A$1,217 per ounce and an AISC of A$1,388 per ounce reflecting the various stages its individual gold projects were at. Gold sales averaged A$1,616 for the quarter.
-
The Tin Division saw the Renison mine (MLX 50%) produce 1,676 tonnes of tin metal at a cash cost of A$14,455 per tonne of tin metal and an AISC of A$19,311 per tonne of tin metal. An unaudited cash inflow of $3.12M was generated. Tin sales averaged a price of A$21,170 per tonne for the quarter and have since risen to approximately A$23,000 per tonne.
-
Within the Nickel Division significant progress with the Public Environmental Review (PER) process was made and a final approval is expected to be imminent. Operationally, a revised high-grade cut-off model for the deposit was completed showing that using a 1.30% cut-off grade, the higher grade resource component is 25 million tonnes at 1.45% Ni, 0.1% Co and 53.5% Fe2O3. Initial mining studies suggest that this higher grade resource can be mined with an estimated 1.5:1 (waste:ore) stripping ratio.
CORPORATE
-

GOLD DIVISION
OVERVIEW
Total gold production for the quarter was 47,591 ounces (including Cannon 3,505 ounces) at a cash cost of $A1,217 per ounce and an AISC of A$1,388 per ounce reflecting the various phases the individual gold operations are at.
Overall Performance for the gold group was temporarily dented by continued lower performance from the Trident Underground Mine at Higginsville, a slower than anticipated shift to ore stoping at Paddy’s Flat (CMGP) and also a poor reconciliation from the Whangamata Open Pit(CMGP). However, all are short-term performance matters and are now behind the operations. Of particular significance is the capital intensive phases at CMGP and the HBJ Underground Mine are beginning to significantly reduce.
Highlights of the Gold Division were:
-
Significant progress was made in the production build at CMGP with the Paddy’s Flat transitioning to ore stoping on the Vivian-Consols Lodes after delayed establishment of mine ventilation and emergency egress networks.
-
An increase in productivity, grade and mine-life at South Kal and the completion of a long-term mine ventilation network.
-
The re-start plan for the Fortnum Project made good progress with engineering and approvals works nearing completion. A re-modelling of ore sources in the initial 3 years of ore feed was completed as was the successful drilling of existing low grade ore stockpiles.
-
Detailed infill drilling at Mt Henry of the top 30 metres returned better than expected results and the project is advancing to replace the Trident Underground Mine as the main source of feed for the Higginsville operations in the second half of this calendar year.
-
The Cannon Mine continued to progress with excellent reconciliations and cost outcomes. Metals X continues to play banker to the project and has profit share of 50% of the surplus after all cost are repaid. The latest indications are that AISC of around $1,000 per ounce are achievable from the pit which will be complete early in 2017.
-
An agreement to buy the Gunga Mine, 30km west of Jubilee mill was made. The acquisition price is $1.5M in cash and a further $1M in a milestone payment when production exceeds 30,000 oz. The current resource at Gunga is1.33 million tonnes at 1.7 g/t Au containing 73,000 oz. Gunga is expected to provide a blended feed for the plant post Cannon until mid-2018.
-
Gold hedging at the end of the quarter stood at 208,750 ounces (including the gold prepay 21,250 oz @ A$1,490.6 per ounce) at an average price of A$1,624.2 per ounce.
-
Excellent exploration results across the operations were received including the following outstanding hits:
HBJ Underground 5.3 m at 12.30 g/t Au from 66.1 m in HBJUG0083 Mt Henry 16 m at 6.6 g/t Au from 12 m in MHGC0127 Paddy’s Flat 13 m at 13.7 g/t Au from 6 m in 16VIDD048 3 m at 297.56 g/t Au from 52 m in 16VIDD05 Trident 3.3 m at 24.32 g/t Au from 153 m in TUG2779

QUARTERLY REPORT 4 FOR THE PERIOD ENDING 31 MARCH 2016
HIGGINSVILLE GOLD OPERATIONS (HGO) (MLX 100%)
The HGO remained in a transition period where the tail end of the Trident mine’s Artemis and Helios lodes is being mined. This area has lower overall grade, is approximately 1100m deep and is enduring spasmodic seismic events which make its extraction rates unpredictable. The ore system continues at depth with grades improving approximately 100m further down plunge into the Pluto lodes. The establishment of the decline access to this area requires significant capital investment including a major upgrade to the ventilation network and inequitable royalty imposts as the gold price increases. Consequently, a decision has been made to defer this development in favour of open pit ores from the Mt Henry gold mine, approximately 75km south of the plant. The Trident Mine will move to a care and maintenance mode.
Open pit mining from the Lake Cowan region continued and a cut-back to the Fairplay Pit just south of the plant commenced during the quarter. Open pit mining at Mt Henry is scheduled to start by mid-year. Infill drilling during the quarter significantly upgraded and confirmed the continuity of the near surface resource with the first stage of the open pit. This will have a low strip ratio with a grade above 2.3 g/t expected.
Quarterly gold production dropped to 18,783 ounces at a cash operating costs of A$1,165 per ounce and an AISC of A$1,363 per ounce. Financial year-to-date gold production now totals 65,892 ounces at a cash cost of A$1,100 per ounce and an AISC of A$1,303 per ounce.
HGO EXPLORATION
At HGO drilling continues to be focused on the Trident Underground Mine, with work this quarter being a combination of conceptual targeting and definition of future stoping panels. 3.3m at 24.32g/t Au from 153m in TUG2779 within the producing Artemis orebody, and 6.8m at 4.47g/t Au from 203m in TUG2810 testing the Pluto target have provided encouragement that Trident will continue to produce a significant volume of high margin ounces over its remaining Life of Mine. Importantly, significant advances have been made in preparing the recent Mount Henry acquisition for mining in the coming financial year.
Infill drilling to validate the recent Metals X resource model is ongoing, with the results returned to date validating our view that selective mining of a higher-grade portion of the Mount Henry resource is possible. Results such as 16m at 6.6g/t Au from 12m in MHGC0127, 22m at 4.35g/t Au from 7m in MHGC0141 and 22m at 5.28g/t Au from 10m in MHGC0230 have reinforced Metals X’s enthusiasm for the project, and positively reinforced the vision of Mount Henry as a long-term source of open pit ore feed for the Higginsville operation.
SOUTH KALGOORLIE OPERATIONS (SKO) (MLX 100%)
A relatively steady performance from SKO during the quarter with directly attributable (excluding Cannon 3,505 oz) ore processed totaling 238,410 tonnes at 1.87 g/t Au and a 90.37% recovery to yield 13,006 ounces.
Underground production from HBJ was steady and focused on the lower grade remnant stoping positions. Overall productivity was hampered by delays in establishing the primary ventilation circuit which was completed subsequent to the end of the quarter. The refurbishment of the old decline advanced to be in a position to access the first virgin lodes under historic mining late in the ensuing quarter which should see an overall increase in mine head grade.
HBJ ore was supplemented by open pit mining at the wholly owned Georges Reward Pit at Bulong and low-grade stocks. Open pit production was 54,078 tonnes at 2.77g/t Au and some 100,102 existing tonnes of low grade stocks were drawn.
Quarterly gold production increased to 13,006 ounces at a cash operating costs of A$1,020 per ounce (excluding Cannon) and an AISC of A$1,145 per ounce. Financial year-to-date gold production now totals 34,643 ounces at a cash cost of A$1,212 per ounce and an AISC of A$1,357 per ounce.
QUARTERLY REPORT 5 FOR THE PERIOD ENDING 31 MARCH 2016
SKO EXPLORATION
At South Kalgoorlie, drilling has concentrated on firming-up mining panels in the HBJ mine as ongoing underground development opens up access to multiple mining fronts within the orebody. Better results at HBJ this quarter have included 5.26m at 12.30g/t Au from 66.1m in HBJUG0083, 3m at 3.23g/t Au from 69m in HBJUG0106 and 4.98m at 9.29g/t Au from 72m in HBJUG0150. Aside from the encouragement provided by the raw assay results, the geology revealed by the core in combination with exposures provided by underground development are adding significantly to the geological understanding of the mineralised system at HBJ. This will translate to better mining and exploration targeting outcomes moving forward.
CANON GOLD MINE (MLX 50% PROFIT SHARE)
Metals X has a financing and profit sharing agreement with Southern Gold Limited (SAU) over the Cannon Mine at Bulong in Western Australia. Pursuant to this agreement, Metals X will manage all technical aspects of the mining operation as well as fund all costs involved with the operation of the mine.
All ore from the mine is batched processed through the SKO Mill and all revenue first goes to repay costs. On the completion of mining surplus funds will be split on 50:50 basis (the profit share). In addition Metals X has made loan funds available to SAU of up to $2.5 million to fund its other working capital requirements. The loan funds earn interest at 8% per annum and are secured by a mortgage over the Cannon Mining Tenement. To date SAU has drawn on $1 million of these loan funds.
Mining has been underway at Cannon since September 2015. The current mine plan will see mining and processing continue until February 2017, after which assessment of underground mining opportunities will take place. Pit to date statistics are:

One parcel of ore was toll processed during the quarter which totaled 43,790 tonnes at 2.68 g/t Au and a 92.85% recovery yielding 3,505 ounces.
All mining physicals and costs are tracking according to expectations.
QUARTERLY REPORT 6 FOR THE PERIOD ENDING 31 MARCH 2016
CENTRAL MURCHISON GOLD PROJECT (CMGP) (MLX 100%)
The CMGP had its first full quarter of production since commissioning in late October 2015. Output was a modest increase over the previous quarter at 12,296 ounces produced from the processing of 371,327 tonnes at a head grade of 1.12 grams per tonne and an overall recovery of 92.14%.
The overall grade reflects a combination of the decision to process all low grade ore produced on a continuous basis through the plant as opposed to only the high grade open pit ores. Further, the grade also reflects some difficult reconciliations against reserve in the first two open pits mined (Batavia & Whangamata).
At Batavia the mine reconciliation against reserves so far has been 130% of tonnes, 72% of grade and 94% of metal, resulting in a higher unit cost per ounce. An additional 28,615 tonnes of low grade (0.92 g/t) was mined and has also been processed on a marginal cost basis.
At the larger Whangamata open pit the issue of segregation of low grade and high grade ore blocks from within the oxidised shear zone has been very difficult and as a consequence a decision was made to aggregate the two categories. On the aggregated basis the reconciliation has been 176% of the tonnes (407,000t) , 62% of the grade (0.84g/t) and 109% of the meta (11,709oz), again resulting in a higher unit cost of production. The impact of this to the start-up months is exacerbated as Whangamata has been 2/3rds of the ore processed so far. Whilst disappointed reconciliation, the impact of this issue is now behind us with these pits coming to an end in the near future.
The ensuing periods will have ore sourced from the Jack Ryan (at Reedy’s) and the Bluebird open pits which are not having the same issues. Most of the pre-strip at Jack Ryan was excavated during the quarter. Access to the Bluebird Pit was re-established and mining recommenced there during the quarter.
At the Paddy's Flat underground mine, timing delays with the establishment of the primary vent circuit and emergency egress had delayed the onset of stoping and also the access to the Prohibition lodes which were the planned early feed sources. Whilst this matter is resolved now, the capital development was continued at a proportionally higher rate in other areas. Ore driving on the Vivian Consols lodes on the first level at Paddy's Flat delivered good exposure and ore. So far reconciliations on this very small section of the overall orebody has been encouraging with mined to ore reserve reconciliations delivering 106% of tonnes, 89% of the grade and 94% of the metal. Processing subsequent to the end of the quarter suggest milled grades are overcalling mined estimates due to the variability and nugget effect of these ores. Encouragingly, productivity from Paddy’s Flat is now building and the Prohibition lodes have now been intersected with encouraging initial signs.
Dewatering at the Big Bell Underground Mine continued with re-access to the old portal expected late in the September 2016 quarter. A revised development plan using the higher cut-off resource estimate announced last quarter is underway. A development plan to commence underground mining at the Comet Mine near Cue was also commenced and submissions for statutory approvals have been lodged.
Quarterly gold production from the start up phase was 12,296 ounces at a cash operating cost of A$1,506 per ounce taking project to date output to 21,230 ounces at a cash operating cost of A$1,343 per ounce and an AISC of A$1,464 per ounce.
CMGP EXPLORATION
At CMGP, significant time and resources were allocated to the first ever underground drilling campaign at the new Paddy’s Flat Underground Mine. This drilling work was conducted to provide information ahead of the development front, and improve definition of ore panels ahead of the commencement of first stoping. Initial results have highlighted the significant endowment of this ore system with 2.6m at 37.11g/t Au from 96m in 16VIDD020, 13m at 13.7g/t Au from 6m in 16VIDD048 and 3m at 297.56g/t Au from 52m in 16VIDD057 being amongst the standout results. Metals X is undertaking the first modern underground ore production at Paddys Flat, where prior to 1985 over 830koz of gold was produced from handheld underground mining at an average grade of 16.8g/t.
QUARTERLY REPORT 7 FOR THE PERIOD ENDING 31 MARCH 2016
FORTNUM GOLD PROJECT (FGP) (MLX 100%)
During the quarter, Metals X continued to progress the Fortnum Gold Project (FGP) toward production. The FGP is a development ready project and located within historic Horseshoe, Peak Hill and Labouchere gold mining centres that were in production until 2006. The operation is leveraged to take advantages of the historical production base (+1.0Moz), synergies with Metals X’s nearby Central Murchison Gold Project and by utilising the existing 1.0Mtpa processing plant and operating infrastructure base which needs refurbishment.
The FGP mining area has recent past production of 11.5 million tonnes at 2.8g/t producing just over 1 million ounces.
The Fortnum Gold Mine has further progressed in the March Quarter towards a re-start implementation plan. The development strategy being worked upon is a simple 4 phase strategy
Phase 1 – Refurbish the plant, re-align permits and approvals, commission and operate on existing low grade ore stockpiles (expected to be able to provide an initial 12 months of feed on their own).
Phase 2 – Commence open pit mining from planned cutbacks to the existing open pits and extensions thereof. Start the mining of these when the plant is operational and slowly replace the lower grade stocks with these higher grade open pit ores.
Phase 3 – Dewater and recommission the Starlight Underground mine and replace/supplement the other ores with these higher grade ores increasing overall production.
Phase 4 – Explore and develop the numerous targets and opportunities to create sustainable production from the existing 2 million ounce resource base and additions to it.
Progress on Phase 1
A review, replacement and application for all permits, licensing and approvals for the project to proceed. The was effectively completed during the quarter with the following key components completed:
-
a. The clearing permits amended and transferred.
-
b. The mining proposals amended and transferred.
-
c. A revised/new Project Management Plan (PMP) approved.
-
d. Groundwater Licences transferred.
-
e. Submissions for Dangerous Goods licences lodged.
-
f. Tailings Dam 2 – works approval amended.
-
g. Quotes for Power Supply underway.
-
h. Scope of Works for Plant Refurbishment completed and tenders being assessed.
-
i. Workers Village partially refurbished.
-
j. Mine dewatering strategy and quotes underway.
-
k. Detailed Geotechnical and Hydrological studies nearing completion.
The LOW-CAPEX re-start plan was confirmed to be achievable with current estimates of $10-$15m being backed with firm quotations.
The strategy to commence ore processing on low grade stocks (only) was validated with drill testing of existing low grade stocks. So far 810,000 tonnes of low grade stock averaging 0.81 g/t has been confirmed with drilling and have been slotted into a plan. A further 500,000t (approx.) of existing stockpiles from past mining are under evaluation and will be check drilled or sampled before being slotted into the development plan. The following table summarises the results and progress:

Phase 2 Progress
The ore reserves estimates for the three open pits closest to the process plant (direct haul) were revised during the quarter. In the case of the southerly extension to the Yarlarweelor Pit, this included a round of validation drilling top confirm the resource model. The results of this drilling is included in Appendix 1. This enabled the planned mining of the first 3 pits to be slotted into the development plan with the following outcomes:

Works are continuing on a number of additional open pit opportunities including Horseshoe, Cassidy, Jubilee, Harmony, 5-Ways, Nathans and Labouchere.
Progress on Phase 3
The data for the previously mined Starlight underground has been collated and is under evaluation. The mine produced 612,000 tonnes at 5.8 g/t (113,000 ounces) from its first 4 levels when it was abruptly stopped by Perilya in 2004. Initial reviews suggest excellent potential to recover remnants and re-start the operation on known extensions and newly outline parallel lodes.
Metals X expects to be in a position to present a complete development plan in the ensuing quarter.
ROVER GOLD PROJECT (MLX 100%)
Due to the wet season in the Tennant Creek Region, no field activity was undertaken at Rover during the quarter. Works did commence on a revised resource model integrating the bonanza high grade gold and copper hits received during the last drill program which targeted the 600-900 m vertical depth area.
QUARTERLY REPORT 9 FOR THE PERIOD ENDING 31 MARCH 2016
TIN DIVISION RENISON PROJECT (MLX 50%)
Tin production for the quarter was 1,676 tonnes, a 12% fall from the previous quarter but in-line with expectations from the mining schedule. The cash costs of tin sales was A$14,455 per tonne of tin metal and the AISC was A$19,311 per tonne of tin metal produced. The project remains cash positive with an unaudited cash inflow of A6.24M generated for the quarter (MLX 50% share $3.12M).
World tin prices had a modest gain (3%) for the quarter and currently sits in the A$22,000 – A$23,000 range. Whilst the price is improving and reported stocks are low, the price continues to remain soft and in-line with the general poor sentiment of commodities overall
In a focus to produce tin at the lowest possible cost, the Joint Venture (JV) made a decision not to re-new the underground mining contract at the end of its term (end of April 2016) and is moving to an owner-operator position. The company believes that the operations have reached a long-term steady-state production level and with the changing landscape of a hungry labour-pool in the Tasmanian mining sector the time is right for such transition. A predominantly new fleet of underground equipment has been acquired and the employment of an owner miner’s team is advanced. It is expected that additional cost saving will be achieved moving forward despite some one-off costs in the next quarter associated with contractor de-mobilisiation.

QUARTERLY REPORT 10 FOR THE PERIOD ENDING 31 MARCH 2016
RENISON EXPLORATION AND DEVELOPMENT
At Renison, work around the producing Area 4 and Lower Federal Zones continues to highlight exciting near-term production opportunities, with outstanding true width results such as 13.5m at 5.41% Sn from 90.7m (U5626) in Area 4 and 4.2m at 18.22% Sn from 4.7m (U5611) in Lower Federal returned this quarter. In addition a hole drilled into Lower Federal appears to have clipped the boundary of a dolomite replacement horizon for a significant portion of its length (making the judgement of true width difficult). This hole has returned an interval averaging above 1% Sn for a length of over 60m, which illustrates the scale of the future opportunity in this massive mineralised system (62.9m at 1.02% Sn from 243.6m in U5492). Renison remains open at depth, along strike and up-plunge.
RENTAILS PROJECT (MLX 50%)
The operating JV completed review of the Rentails tin fuming technologies during the quarter. The planned Ausmelt technology for tin fuming was compared against the proprietary Box-fumer technology of Yunnan Tin Group. The conclusions were that any saving in capital and/or operating costs were offset by the copper credit from tapping a copper matte from the Ausmelt top- lance furnace.
The JV partners agreed to review and update the feasibility study for Rentail’s and refresh its capital cost and construction methodology as the Australian dollar tin price was approaching a level that made the development feasible and bankable.
QUARTERLY REPORT 11 FOR THE PERIOD ENDING 31 MARCH 2016
NICKEL DIVISION WINGELLINA PROJECT (MLX 100%)
As advised in the December quarterly report the final Public Environmental Review (PER) document was completed and approved by the EPA for release to the public for an 8 week review period on 14 September 2015 and ended on 9 November 2015. There was a total of 6 submissions received by the department of which none of the submission raised any specific issues that required a response from Metals X. The Board of the EPA has now considered the PER and the Office of the Department of the EPA is now currently finalizing its recommendations for final approval. This is a significant milestone for the Wingellina Nickel-Cobalt project as it completes a further significant step towards the development of the project.
Interaction with the State and Federal Governments in relation to infrastructure requirements within Central Australia continued during the quarter. An application has been submitted to the NT Government to obtain “Significant Project Status” for the road and gas infrastructure, which will result in further cooperation by the territory. Strong support from the other states and Commonwealth is ongoing.
During the quarter a review of the resource model was completed at varying cut-off grades as part of determining the capability of a smaller but higher grade resource to be mined and processed using new pyro-metallurgical processes for nickel recovery.
The revised model used geostatistical analysis specific to mining on a selective basis. Objectively, using a 1.30% cut-off grade, the higher grade resource component is 25 million tonnes at 1.45% Ni, 0.1% Co and 53.5% Fe2O3. Initial mining studies suggest that this higher grade resource can be mined with an estimated 1.5 : 1 (waste:ore) stripping ratio. Comparisons of both resource models are made below:

industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fre assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. • Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc). • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fne/coarse material. |
• Diamond Drilling The bulk of the data used in resource calculations at Trident has been gathered from diamond core. Four types of diamond core sample have been historically collected. The predominant sample method is half-core NQ2 diamond with half-core LTK60 diamond, Whole core LTK48 diamond and whole core BQ also used. This core is logged and sampled to geologically relevant intervals. The bulk of the data used in resource calculations at Chalice has been gathered from diamond core. The predominant drilling and sample type is half core NQ2 diamond. Occasionally whole core has been sampled to streamline the core handling process. Historically half and whole core LTK60 and half core HQ diamond have been used. This core is logged and sampled to geologically relevant intervals. • Face Sampling Each development face / round is chip sampled at both Trident and Chalice. One or two channels are taken per face perpendicular to the mineralisation. The sampling intervals are domained by geological constraints (e.g. rock type, veining and alteration / sulphidation etc.) with an efort made to ensure each 3kg sample is representative of the interval being extracted. Samples are taken in a range from 0.1 m up to 1.2 m in waste / mullock. All exposures within the orebody are sampled. • Sludge Drilling Sludge drilling at Chalice and Trident is performed with an underground production drill rig. It is an open hole drilling method using water as the fushing medium, with a 64 mm or 89 mm hole diameter. Samples are taken twice per drill steel (1.9 m steel, 0.8 m sample). Holes are drilled at sufcient angles to allow fushing of the hole with water following each interval to prevent contamination. • RC Drilling For Fairplay, Vine, Lake Cowan, Two Boys, Mousehollow, Pioneer and Eundynie the bulk of the data used in the resource estimate is sourced from RC drilling. Minor RC drilling is also utilised at Trident, Musket, Chalice and the Palaeochannels (Wills, Pluto, Mitchell 3 & 4). Drill cuttings are extracted from the RC return via cyclone. The underfow from each 1 m interval is transferred via bucket to a four tiered rife splitter, delivering approximately three kilograms of the recovered material into calico bags for analysis. The residual material is retained on the ground near the hole. Samples too wet to be split through the rife splitter are taken asgrabs and are recorded as such. |

| • RAB / Air Core Drilling Drill cuttings are extracted from the RAB and Aircore return via cyclone. 4 m Composite samples are obtained by spear sampling from the individual 1 m drill return piles; the residue material is retained on the ground near the hole. In the Palaeochannels 1 m samples are rife split for analysis. There is no RAB or Aircore drilling used in the estimation of Trident, Chalice, Corona, Fairplay, Vine, Lake Cowan and Two Boys. SKO SKO is a long-term producing operation with a long history of drilling and sampling to support exploration and resource development. • Sampling Techniques Chips from the RC drilling face-sampling hammer are collected for assaying. Sample return lines are cleaned with compressed air each metre and the cyclone sample collector is cleaned following each rod. Samples are rife split through a three-tier splitter with a split ~3kg sample (generally at 1 m intervals) pulverised to produce a 30g charge analysed via fre assay. Diamond drill-core is geologically logged and then sampled according to geology (minimum sample length of 0.4 m to maximum sample length of 1.5 m) – where consistent geology is sampled, a 1 m length is used for sampling the core. The core is sawn half-core with one half sent of for analysis. Samples have been collected from numerous other styles of drilling at SKO, including but not limited to RAB, aircore, blast-hole, sludge drilling and face samples. • Drilling Techniques Historical data includes DD, RC, RAB and aircore holes drilled between 1984 and 2010. Not all the historical drilling programmes at SKO are documented and many historical holes are assigned a drill type of ‘unknown’. Over 4,000 km of drilling has been completed on the tenure. Drilling by the most recent previous owners (Alacer Gold Corporation) has predominantly been RC, with minor DD and aircore drilling. RC drilling is used predominantly for defning and testing for near-surface mineralisation and utilises a face sampling hammer with the sample being collected on the inside of the drill-tube. RC drillholes utilise downhole single or multi shot cameras. Drillhole collars were surveyed by onsite mine surveyors. Diamond drilling is used for either testing / targeting deeper mineralised systems or to defne the orientation of the host geology. Many of these holes had RC pre-collars generally to a depth of between 60 – 120 m, followed by a diamond tail. The majority of these holes have been drilled at NQ2 size with minor HQ sized core. All diamond holes were surveyed during drilling with downhole cameras, and then at end of hole using a Gyro Inclinometer at 5 or 10 m intervals. Drillhole collars were surveyed by onsite mine surveyors. |

| • Sample Recovery Sample recovery is generally good, and there is no indication that sampling presents a material risk for the quality of the evaluation of any deposit at SKO. CMGP • Diamond Drilling A signifcant portion of the data used in resource calculations at the CMGP has been gathered from diamond core. Multiple sizes have been used historically. This core is geologically logged and subsequently halved for sampling. Grade control holes may be whole-cored to streamline the core handling process if required. • Face Sampling At each of the major past underground producers at the CMGP, each development face / round is horizontally chip sampled. The sampling intervals are domained by geological constraints (e.g. rock type, veining and alteration / sulphidation etc.). The majority of exposures within the orebody are sampled. • Sludge Drilling Sludge drilling at the CMGP was performed with an underground production drill rig. It is an open hole drilling method using water as the fushing medium, with a 64 mm (nominal) hole diameter. Sample intervals are ostensibly the length of the drill steel. Holes are drilled at sufcient angles to allow fushing of the hole with water following each interval to prevent contamination. Sludge drilling is not used to inform resource models. • RC Drilling RC drilling has been utilised at the CMGP. Drill cuttings are extracted from the RC return via cyclone. The underfow from each interval is transferred via bucket to a four tiered rife splitter, delivering approximately three kilograms of the recovered material into calico bags for analysis. The residual material is retained on the ground near the hole. Composite samples are obtained from the residue material for initial analysis, with the split samples remaining with the individual residual piles until required for re-split analysis or eventual disposal. • RAB / Aircore Drilling Combined scoops from bucket dumps from cyclone for composite. Split samples taken from individual bucket dumps via scoop. RAB holes are not included in the resource estimate. • Blast Hole Drilling Cuttings sampled via splitter tray per individual drill rod. Blast holes not included in the resource estimate. All geology input is logged and validated by the relevant area geologists, incorporated into this is assessment of sample recovery. No defned relationship exists between sample recovery and grade. Nor has sample bias due to preferential loss or gain of fne or coarse material been noted. |

HGO • NQ2 and LTK60 diameter core is sawn half core using a diamond-blade saw, with one half of the core consistently taken for analysis. LTK48 and BQ are whole core sampled. Sludge samples are dried then rife split. • The un-sampled half of diamond core is retained for check sampling if required. • For the onsite Intertek facility the entire dried sample is jaw crushed (JC2500 or Boyd Crusher) to a nominal 85% passing 2 mm with crushing equipment cleaned between samples. An analytical sub-sample of approximately 500-750 g is split out from the crushed sample using a rife splitter, with the coarse residue being retained for any verifcation analysis. Sample preparation techniques are appropriate for the type of analytical process. • Where Fire assay has been used the entire half core sample (3-3.5 kg) is crushed and pulverised (single stage mix and grind using LM5 mills) to a target of 85-90% passing 75μm in size. A 200g sub-sample is then separated out for analysis. • Core and underground face samples are taken to geologically relevant boundaries to ensure each sample is representative of a geological domain. Sludge samples are taken to nominal sample lengths. • The sample size is considered appropriate for the grain size of the material being sampled. • For RC, RAB and Aircore chips regular feld duplicates are collected and analysed for signifcant variance to primary results. • RAB and Aircore sub-samples are collected through spear sampling. SKO • NQ2 and HQ diameter core is sawn half core using a diamond-blade saw, with one half of the core consistently taken for analysis. Smaller sized core (LTK48 and BQ) are whole core sampled. The un-sampled half of diamond core is retained for check sampling if required. • SKO staf collect the sample in pre-numbered calico sample bags which are then submitted to the laboratoryfor analysis. Deliveryof the sample is bya SKO staf member. |

Delivery of the sample to the laboratory is by a SKO staf member. • Upon delivery to the laboratory, the sample numbers are checked by the SKO staf member against the sample submission sheet. Sample numbers are recorded and tracked by the laboratory using electronic coding. • Sample preparation techniques are considered appropriate for the style of mineralisation being tested for – this technique is industry standard across the Eastern Goldfelds. CMGP • Blast holes -Sampled via splitter tray per individual drill rods. • RAB / AC chips - Combined scoops from bucket dumps from cyclone for composite. Split samples taken from individual bucket dumps via scoop. • RC - Three tier rife splitter (approximately 5kg sample). Samples generally dry. • Face Chips - Nominally chipped horizontally across the face from left to right, sub-set via geological features as appropriate. • Diamond Drilling - Half-core niche samples, sub-set via geological features as appropriate. Grade control holes may be whole-cored to streamline the core handling process if required. • Chips / core chips undergo total preparation. • Samples undergo fne pulverisation of the entire sample by an LM5 type mill to achieve a 75µ product prior to splitting. • QA/QC is currently ensured during the sub-sampling stages process via the use of the systems of an independent NATA / ISO accredited laboratory contractor. A signifcant portion of the historical informing data has been processed by in-house laboratories. • The sample size is considered appropriate for the grain size of the material being sampled. • The un-sampled half of diamond core is retained for check sampling if required. For RC chips regular feld duplicates are collected and analysed for signifcant variance toprimaryresults. |

| Quality of assay data and laboratory tests |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
HGO • At the Intertek on-site facility, analysis is performed using a 500g PAL method. The accurately weighed sub-sample is further processed utilising a PAL1000B to grind the sample to a nominal 90% passing 75µm particle size, whilst simultaneously extracting any cyanide amenable gold liberated into a Leachwell liquor. The resulting liquor is then analysed for gold content by organic extraction with fame AAS fnish, with an overall method detection limit of 0.01ppm Au content in the original sample. This method is appropriate for the type and magnitude of mineralisation at Higginsville. • Quality control procedures include the use of standards, blanks and duplicates. Standards and duplicates are used to test both the accuracy and precision of the analytical process, while blanks are employed to test for contamination during the sample preparation stage. The analyses have confrmed the analytical process employed at Higginsville is adequately precise and accurate for use aspart of the mineral resource estimation. |

| SKO • Only nationally accredited laboratories are used for the analysis of the samples collected at SKO. • The laboratory dry and if necessary (if the sample is >3kg) rife split the sample, which is then jaw crushed and pulverised (the entire 3kg sample) in a ring mill to a nominal 90% passing 75 microns. All recent RC and Diamond core samples are analysed via Fire Assay, which involves a 30g charge (sub-sampled after the pulverisation) of the analytical pulp being fused at 1050°C for 45 minutes with litharge. The resultant metal pill is digested in aqua regia and the gold content determined by atomic adsorption spectrometry – detection limit is 0.01 ppm Au. • Quality Assurance and Quality Control (QA/QC) samples are routinely submitted by SKO staf and comprise standards, blanks, assay pills, feld duplicates, lab duplicates and repeat analyses. The results for these QA/QC samples are routinely analysed by Senior Geologists with any discrepancies dealt with in conjunction with the laboratory prior to the analytical data being imported into the database. • There is limited information available on historic QA/QC procedures. SKO has generally accepted the available data at face value and carry out data validation procedures as each deposit is re-evaluated. • The analytical techniques used are considered appropriate for the style of mineralisation being tested for – this technique is industry standard across the Eastern Goldfelds. • Ongoing production data generally confrms the validity of prior sampling and assaying of the mined deposits to within acceptable limits of accuracy. CMGP • Recent drilling was analysed by fre assay as outlined below; » A 50g sample undergoes fre assay lead collection followed by fame atomic adsorption spectrometry. » The laboratory includes a minimum of 1 project standard with every 22 samples analysed. » Quality control is ensured via the use of standards, blanks and duplicates. • No signifcant QA/QC issues have arisen in recent drilling results. • Historical drilling has used a combination of Fire Assay, Aqua Regia and PAL analysis. • These assaymethodologies are appropriate for the resources inquestion. |

HGO • Collar coordinates for surface drill-holes were generally determined by GPS, with underground drill-holes generally determined by survey pick-up. Downhole survey measurements for most surface diamond holes were by Gyro-compass at 5 m intervals. Holes not gyro-surveyed were surveyed using Eastman single shot cameras at 20 m intervals. Downhole surveys for underground diamond drill-holes were taken at 15 – 30 m intervals by Refex single-shot cameras. Routine survey pick-ups of underground and surface holes where they intersected development indicates (apart from some minor discrepancies with pre-Avoca drilling) a survey accuracy of less than 5 m. • All drilling and resource estimation is undertaken in local mine grid at the various projects. • Topographic control is generated from Diferential GPS. This methodology is adequate for the resource in question. SKO • Collar coordinates for surface RC and diamond drill-holes were generally determined by either RTK-GPS or a total station survey instrument. Underground drill-hole locations (Mount Marion and HBJ) were all surveyed using a Leica refectorless total station. • Recent surface diamond holes were surveyed during drilling with down-hole single shot cameras and then at the end of the hole by Gyro-Inclinometer at 5 or 10 mm intervals. Holes not gyro-surveyed were surveyed using Eastman single shot cameras at 20 m intervals. RC drill-holes utilised down-hole single shot camera surveys spaced every 15 to 30 m down- hole. • Down-hole surveys for underground diamond drill-holes were taken at 15 – 30 m intervals by Refex single-shot cameras. • The orientation and size of the project determines if the resource estimate is undertaken in local or MGA 94 grid. Each project has a robust conversion between local, magnetic and an MGA grid which is managed by the SKO survey department. • Topographic control is generated from RTK GPS. This methodology is adequate for the resources inquestion. |

| CMGP • All data is spatially oriented by survey controls via direct pickups by the survey department. Drillholes are all surveyed downhole, deeper holes with a Gyro tool if required, the majority with single / multishot cameras. • All drilling and resource estimation is preferentially undertaken in local mine grid at the various sites. • Topographic control is generated from a combination of remote sensing methods and ground- based surveys.

| Data spacing and distribution | • Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufcient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifcations applied. • Whether sample compositing has been applied. |
HGO • Drilling in the underground environment at Trident is nominally carried-out on 20 m x 30 m spacing for resource defnition and in flled to a 10 m x 15 m spacing with grade control drilling. At Trident the drill spacing below the 500RL widens to an average of 40 m x 80 m. • Drilling at the Lake Cowan region is on a 20 m x 10 m spacing. Historical mining has shown this to be an appropriate spacing for the style of mineralisation and the classifcations applied. • Compositing is carried out based upon the modal sample length of each project. SKO • HBJ: Drill spacing ranges from 10 m x 5 m grade control drilling to 100 m x 100 m at deeper levels of the resource. The majority of the Indicated Resource is estimated using a maximum drill spacing of 40 m x 40 m. The resource has been classifed based on drill density with mining of the 2.2km long HBJ Open-Pit confrming that the data spacing is adequate for the resource classifcations applied. • Mount Martin: Drill spacing ranges from 10 m x 5 m grade control drilling to 60 m x 60 m for the Inferred areas of the resource. The drill spacing for the majority of the Indicated Resource is 20 m x 20 m. The resource has been classifed primarily on drill density and the confdence in the geological/grade continuity – the data spacing and distribution is deemed adequate for the estimation techniques and classifcations applied. • Pernatty: Drill spacing for the reported resource is no greater than 60 m x 60 m with the majority of the Indicated resource based on a maximum spacing of 40 m x 40 m. The geological interpretation of the area is well understood, and is supported by the knowledge from open pit and underground operations. However given the mineralisation is controlled by shear zones the mineralisation continuity is considered to be less understood. The resource is classifed on a combination of drill density and the number of samples used to estimate the resource blocks. |

| • Mount Marion: Drill-spacing ranges from 20 m x 20 m to no greater than 60 m x 60 m for the reported resource Given that the geological and mineralisation understanding is well established via mining operations, this drill-spacing is considered adequate for the classifcations applied to the resource. Compositing is carried out based upon the modal sample length of each project. CMGP • Data spacing is variable dependent upon the individual orebody under consideration. A lengthy history of mining has shown that this approach is appropriate for the Mineral Resource estimation process and to allow for classifcation of the resources as they stand. • Compositingis carried out based upon the modal sample length of each individual domain. |

| Orientation of data in relation to geological structure |
• Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
• Drilling intersections are nominally designed to be normal to the orebody as far as underground infrastructure constraints / topography allows. • Development sampling is nominally undertaken normal to the various orebodies. • Where drilling angles are sub optimal the number of samples per drill hole used in the estimation has been limited to reduce any potential bias. • It is not considered that drillingorientation has introduced an appreciable samplingbias. |

• The Higginsville region has an exploration and production history in excess of 30 years. • The SKO tenements have an exploration and production history in excess of 100 years. • The CMGP tenements have an exploration and production history in excess of 100 years. • Metals X work has generally confrmed the veracity of historic exploration data. HGO • Trident is hosted primarily within a thick, weakly diferentiated gabbro with subordinate mafc and ultramafc lithologies and comprises a series of north-northeast trending, shallowly north-plunging mineralised zones. The deposit comprises two main mineralisation styles; large wallrock-hosted ore-zones comprising sigmoidal quartz tensional vein arrays and associated metasomatic wall rock alteration hosted exclusively within the gabbro; • and thin, lode-style, nuggetty laminated quartz veins that formed primarily at sheared lithological contacts between the various mafc and ultramafc lithologies. • Lake Cowan mineralisation can be separated into two types. Structurally controlled primary mineralisation in ultramafcs, basalts and felsics host (e.g. Louis, Josephine and Napoleon), and saprolite / palaeochannel hosted supergene hydromorphic deposits, including Sophia, Brigitte and Atreides. SKO • HBJ: The HBJ lodes form part of a gold mineralised system along the Boulder-Lefroy shear zone that is over 5km long and includes the Celebration, Mutooroo, HBJ and Golden Hope open- pit and underground mines. The lodes are hosted within a steeply-dipping, north-northwest striking package of mafc, ultramafc and sedimentary rocks and schists that have been intruded by felsic to intermediate porphyries. Gold mineralisation is structurally controlled and is focused along lithological contacts, within stockwork and tensional vein arrays and within shear zones. The main mineralised zone has a length in excess of 1.9 km and an average width of 40 m in the Jubilee workings but is generally narrower to the north in the Hampton -Boulder workings. • Mount Marion: • The Mount Marion deposit is located on the eastern side of the Coolgardie Domain within a fexure in the Karramindie Shear Zone. It is hosted within a sub-vertical sequence of meta- komatiites intercalated with metasediments that have been metamorphosed to amphibolite facies. Gold mineralisation occurs in a footwall and hangingwall lode, each ranging in thickness from 2 to 15 m. The mineralisation plunges steeply to the west and is open at depth. • Mount Martin: The Mount Martin Tribute Area, is located within a regional scale north-northwest trending Archean Greenstone Belt. Within the Mount Martin - Carnilya area, the greenstone belt comprises a mixed sequence of ultramafc (predominantly komatiitic) and fne-grained, variably sulphidic sedimentary lithologies with subsidiary mafc units. Known gold and nickel mineralisation at the Mount Martin Mine is associated with a series of stacked, westerly dipping, sulphide and quartz-carbonate bearing lodes which are mainly hosted within intensely deformed and altered chloritic schists sandwiched between talc-carbonate ultramafc lithologies. |

| • Pernatty: The Pernatty deposit is hosted within a granophyric phase of a gabbro and is controlled by a structurally complex interaction of a number of major shear zones. Shearing has altered the original granophyric quartz dolerite to a biotite-carbonate-plagioclase-pyrite schist. The sequence has also been intruded by mafc and felsic porphyritic dykes, which are also mineralised. CMGP • The CMGP is located in the Achaean Murchison Province, a granite-greenstone terrane in the northwest of the Yilgarn Craton. Greenstone belts trending north-northeast are separated by granite-gneiss domes, with smaller granite plutons also present within or on the margins of the belts. • Mineralisation at Big Bell is hosted in the shear zone (Mine Sequence) and is associated with the post-peak metamorphic retrograde assemblages. Stibnite, native antimony and trace arsenopyrite are disseminated through the K-feldspar-rich lode schist. These are intergrown with pyrite and pyrrhotite and chalcopyrite. Mineralisation outside the typical Big Bell host rocks (KPSH), for example 1,600N and Shocker, also display a very strong W-As-Sb geochemical halo. • Numerous gold deposits occur within the Cuddingwarra Project area, the majority of which are hosted within the central mafc-ultramafc ± felsic porphyry sequence. Within this broad framework, mineralisation is shown to be spatially controlled by competency contrasts across, and fexures along, layer-parallel D2 shear zones, and is maximised when transected by corridors of northeast striking D3 faults and fractures. • The Great Fingall Dolerite hosts the majority gold mineralisation within the portion of the greenstone belt proximal to Cue (The Day Dawn Project Area). Unit AGF3 is the most brittle of all the fve units and this characteristic is responsible for its role as the most favourable lithological host togold mineralisation in the Greenstone Belt. |

Unit AGF3 is the most brittle of all the fve units and this characteristic is responsible for its role as the most favourable lithological host to gold mineralisation in the Greenstone Belt. • The Paddy’s Flat area is located on the western limb of a regional fold, the Polelle Syncline, within a sequence of mafc to ultramafc volcanics with minor interfow sediments and banded iron-formation. The sequence has also been intruded by felsic porphyry dykes prior to mineralisation. Mineralisation is located along four sub-parallel trends at Paddy’s Flat which can be summarised as containing three dominant mineralisation styles: Sulphide replacement BIF hosted gold. Quartz vein hosted shear-related gold. Quartz-carbonate-sulphide stockwork vein and alteration related gold. • The Yaloginda area is a gold-bearing Archaean greenstone belt situated ~15 km south of Meekatharra. The deposits in the area are hosted in a strained and metamorphosed volcanic sequence that consists primarily of ultramafc and high-magnesium basalt with minor komatiite, peridotite, gabbro, tholeiitic basalt and interfow sediments. The sequence was intruded by a variety of felsic porphyry and interme- diate sills and dykes. • The Reedy’s mining district is located approximately 15 km to the south-east to Meekatharra and to the south of Lake Annean. The Reedy gold deposits occur within a north-south trending greenstone belt, two to fve kilometres wide, composed of volcano-sedimentary sequences and separated multiphase syn- and post-tectonic granitoid complexes. Structurally controlled the gold occurs at the sheared contacts of dolerite, basalt, ultramafc schist,quartz-feldsparporphyry, and shale. |

The bulk of the data used in resource calculations at Renison has been gathered from diamond core. Three sizes have been used historically NQ2 (45.1 mm nominal core diameter), LTK60 (45.2 mm nominal core diameter) and LTK48 (36.1 mm nominal core diameter), with NQ2 currently in use. This core is geologically logged and subsequently halved for sampling. Grade control holes may be whole-cored to streamline the core handling process if required. NQ and HQ core sizes have been recorded as being used at Mount Bischof. This core is geologically logged and subsequently halved for sampling. There is no diamond drilling for the Rentails Project. • Face Sampling Each development face / round is horizontally chip sampled at Renison. The sampling intervals are domained by geological constraints (e.g. rock type, veining and alteration / sulphidation etc.). Samples are taken in a range from 0.3 m up to 1.2 m in waste / mullock. All exposures within the orebody are sampled. A similar process would have been followed for historical Mount Bischof face sampling. There is no face sampling for the Rentails Project. • Sludge Drilling Sludge drilling at Renison is performed with an underground production drill rig. It is an open hole drilling method using water as the fushing medium, with a 64 mm (nominal) hole diameter. Sample intervals are ostensibly the length of the drill steel. Holes are drilled at sufcient angles to allow fushing of the hole with water following each interval to prevent contamination. There is no sludge drilling for the Mount Bischof Project. There is no sludge drilling for the Rentails Project. • RC Drilling RC drilling has been utilised at Mount Bischof. Drill cuttings are extracted from the RC return via cyclone. The underfow from each interval is transferred via bucket to a four tiered rife splitter, delivering approximately three kilograms of the recovered material into calico bags for analysis. The residual material is retained on the ground near the hole. Composite samples are obtained from the residue material for initial analysis, with the split samples remaining with the individual residual piles until required for re-split analysis or eventual disposal. There is no RC drillingfor the Renison Project. |

| • Percussion Drilling This drilling method was used for the Rentails project and uses a rotary tubular drilling cutter which was driven percussively into the tailings. The head of the cutting tube consisted of a 50 mm diameter hard tipped cutting head inside which were ftted 4 spring steel fngers which allowed the core sample to enter and then prevented it from falling out as the drill tube was withdrawn from the drill hole. There is no percussion drilling for the Renison Project. There is no percussion drilling for the Mount Bischof Project. All geology input is logged and validated by the relevant area geologists, incorporated into this is assessment of sample recovery. No defned relationship exists between sample recovery and grade. Nor has sample bias due to preferential loss or gain of fne or coarse material been noted. |

• Drill core is halved for sampling. Grade control holes may be whole-cored to streamline the core handling process. • Samples are dried at 90°C, then crushed to <3 mm. Samples are then rife split to obtain a sub-sample of approximately 100g which is then pulverized to 90% passing 75um. 2g of the pulp sample is then weighed with 12g of reagents including a binding agent, the weighed sample is then pulverized again for one minute. The sample is then compressed into a pressed powder tablet for introduction to the XRF. This preparation has been proven to be appropriate for the style of mineralisation being considered. • QA/QC is ensured during the sub-sampling stages process via the use of the systems of an independent NATA / ISO accredited laboratory contractor. • The sample size is considered appropriate for the grain size of the material being sampled. • The un-sampled half of diamond core is retained for check sampling if required. • For RC chips regular feld duplicates are collected and analysed for signifcant variance to primaryresults. |

These assay methodologies are appropriate for the resource in question. • All assay data has built in quality control checks. Each XRF batch of twenty consists of one blank, one internal standard, one duplicate and a replicate, anomalies are re-assayed to ensure quality control. • Specifc gravity / density values for individual areas are routinely sampled during all diamond drillingwhere material is competent enough to do so. |

Renison is the largest of three major Skarn, carbonate replacement, pyrrhotite-cassiterite deposits within western Tasmania. The Renison Mine area is situated in the Dundas Trough, a province underlain by a thick sequence of Neoproterozoic-Cambrian siliciclastic and volcaniclastic rocks. At Renison there are three shallow-dipping dolomite horizons which host replacement mineralisation. • Mount Bischof is the second of three major Skarn, carbonate replacement, pyrrhotite- cassiterite deposits within western Tasmania. The Mount Bischof Mine area is situated within the Dundas Trough, a province underlain by a thick sequence of Neoproterozoic- Cambrian siliciclastic and volcaniclastic rocks. At Mount Bischof folded and faulted shallow-dipping dolomite horizons host replacement mineralisation with fuid interpreted to be sourced from the forceful emplacement of a granite ridge and associated porphyry intrusions associated with the Devonian Meredith Granite, which resulted in the complex brittle / ductile deformation of the host rocks. Lithologies outside the current mining area are almost exclusively metamorphosed siltstones. Major porphyry dykes and faults such as the Giblin and Queen provided the major focus for ascending hydrothermal • fuids from a buried ridge of the Meredith Granite. Mineralisation has resulted in tin-rich sulphide replacement in the dolomite lodes, greisen and sulphide lodes in the porphyry and fault / vein lodes in the major faults. All lodes contain tin as cassiterite within sulphide mineralisation with some coarse cassiterite as veins throughout the lodes. • The Rentails resource is contained within three Tailing Storage Facilities (TSF’s) that have been built up from the processing of tin ore at the Renison Bell mine over the period 1968 to 2013. |

drilling (DD) techniques. The Mt Henry (MH) resource database subset contains 743 RC & DD holes for a total of 59,401m. • The grid drill spacing is typically 25m X 25m over the extent of the mineralisation. • RC holes were sampled by collecting 1m samples and splitting then down using either on- board rig or manual rife splitters to produce an assay sample of ~3kg size. • Diamond holes are typically NQ2 (NQ for some historical holes) & occasionally HQ size and were sampled by cutting the core in half or quarter for the HQ core over geologically logged intervals between 20cm and 1m in length. • All recent Panoramic resource assay samples were submitted to SGS Laboratories in Perth for gold analysis by FA50 (Fire Assay) technique. Of the historical RC & DD gold assays in the database, the dominant assay methodology is Fire Assay. A minor proportion of the data (4%) has been assayed via Aqua Regia. |
| • The drilling methods used on this deposit are predominantly RC and DD drilling. The RC drilling was typically completed using 5¼ inch hammers and recently 5¼ inch face sampling hammers. • The DD drilling was typically NQ (47.6mm), and more recently NQ2 (50mm) and HQ (63.5mm) diameter core. • HQ size core was typicallydrilled asgeotechnical holes from surface byPanoramic. |

| • RC sample recoveries were monitored by Panoramic by recording visual estimates of the sample bags prior to sampling. Typical recoveries for RC were greater than 90%. • Core recovery is noted during drilling and geological logging processes as a percentage recovered vs. expected drill length.

• Both historical NQ and recent NQ2 core was typically sawn in half and half core sampled. Recent HQ geotechnical core was quarter core sampled where mineralised. Core sample lengths typically varied between 0.2 and 1.0 metre. • The standard RC sample length is 1 metre with samples collected directly from the rig cyclone system. The individual 1m RC samples are then reduced to a 3-5kg assay sample by either automated on-board rig splitters or manually by rife splitting. • The sample preparation process for all samples submitted for analysis follow accepted industry standards, including oven drying sample for a minimum of 8 hrs, crushing and pulverising to 85% passing 75 microns. • Quality control procedures have included the insertion of standards, blanks and duplicates to monitor the sampling and analytical process. • The sample sizes used are accepted industry standard sizes used extensively throughout the goldfelds and are appropriate for the style of deposit. |

• The standard analytical technique used is Fire Assay, mostly by AAS fnished. Of the 43,478 Au assays in the MH resource database subset, 2,851 historical assays (7%) do not have a recorded technique or are by technique other than Fire Assay. Where non gold analyses exist they are either by AAS or ICP OES determination. • No other geophysical or analytical tools have been used to estimate grade. • QA/QC has been completed routinely during all sampling throughout the life of the Project; though less so historically than more recently. The QA/QC results indicate that the RC and DD assays being used for resource estimation are a fair representation of the material that has been sampled. |

• The deposit is very continuous in terms of mineralisation and grade intercepts. The continuity and consistency of the grade intercepts in section and along-strike provides strong confdence in the verifcation of the grade and style of deposit. he similarity and consistency of intersections reported by past operators over many years is further verifcation of the reliability of the data. • No recent twin holes were completed. Historical twin holes verifed mineralisation continuity. Infll verifcation holes were completed by Panoramic to test both geological and mineralisation continuity on selected sections. In each instance the expected geological and mineralogical interpretation was confrmed and no major discrepancies were identifed. • Logging was completed in logging code protected MS Excel templates on laptops and then imported into the Project SQL database for validation. Sections were then generated and visual validation completed to ensure integrity of the data. • No adjustments were made to assaydata. |

| Geology | • Deposit type, geological setting and style of mineralisation. |
• The Mt Henry Project covers 347km2of the prolifc South Norseman-Wiluna Greenstone belt |
| of the Eastern Goldfelds in Western Australia. • Although the greenstone rocks from the Norseman area can be broadly correlated with those of the Kalgoorlie – Kambalda region they form a distinct terrain which is bounded on all sides by major regional shears. The Norseman Terrane has prominent banded iron formations which distinguish it from the Kalgoorlie – Kambalda Terrane. • The Mt Henry gold deposit is hosted by a silicate facies BIF unit within the Noganyer Formation. Gold mineralisation is predominantly hosted by the silicate facies BIF unit but is also associated with minor meta-basalt and dolerite units that were mostly emplaced in the BIF prior to mineralisation. The footwall to the BIF is characterised by a sedimentary schistose unit and the hanging wall by the overlying dolerites of the Woolyeener Formation. • The Mt Henry gold deposit is classifed as an Archean, orogenic shear hosted deposit. The main lode is an elongated, shear-hosted body, 1.9km long by 6 - 10 metres wide and dips 65-75 degrees towards the west. • Mineralisation is pervasive within sheared BIF throughout the entire length of the deposit; however there are discrete zones (or shoots) that contain higher grades and thicker intervals of mineralisation that plunge to the north-northwest. The host shear to the mineralisation strikes north-south and dips 60 degrees towards the west, more or less contiguously with the upper contact of the BIF unit with the overlying Woolyeener Formation. The relative movement is reverse (footwall down). There does not appear to be any signifcant strike- slip component. Minor mineralisation is also associated with other shear zones. These typically either emanate from the main shear or are associated with other discrete shears stratigraphically lower down in the BIF unit. In addition to these footwall lodes, two small discrete supergene lodes are recognised. • Sulphide minerals range from trace to 10%. The predominant sulphide is pyrrhotite with minor pyrite, arsenopyrite, chalcopyrite and marcasite. The pyrrhotite is often formed by the replacement and sulphidisation of magnetite. Gold occurs in narrow discrete quartz veins, and in clouds within silicate minerals. It also occurs in close proximity or attached to sulphide minerals, particularly pyrrhotite. • The mineralisation is infrequentlycut byfat lying, dilationalpegmatite dykes and sills. |

| Database integrity Site visits Geological interpretation |
• Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. • Data validation procedures used. • Comment on any site visits undertaken by the Competent Person and the outcome of those visits. • If no site visits have been undertaken indicate why this is the case. • Confdence in (or conversely, the uncertainty of ) the geological interpretation of the mineral deposit. • Nature of the data used and of any assumptions made. • The efect, if any, of alternative interpretations on Mineral Resource estimation. • The use of geology in guiding and controlling Mineral Resource estimation. • The factors afecting continuity both of grade and geology. |
• Database integrity is maintained via the use of DataShed software which restricts access to the SQL database. DataShed prevents the import of invalid data. • Data validation was completed internally in SQL Server by setting allowable and expected values. Automated queries are run as the data is imported to ensure it meets specifed criteria. • For resource estimation a subset of the SQL database, restricting the data to the Mt Henry Resource area was exported into an MS Access database. Additional data checks were run to ensure appropriate data robustness for the Resource Estimation. • Mr Russell undertakes regular visits to site. • systematic approach to ensure that the resultant estimated Mineral Resource fgure was both sufciently constrained, and representative of the expected sub-surface conditions. In all aspects of resource estimation the factual and interpreted geology was used to guide the development of the interpretation. • The confdence in the geological interpretation is high, as the overall form of the interpretation has been confrmed by extensive past mining of the deposit. • There is a strong geological control to the mineralisation interpretation. The deposit is essentially strata hosted within a sheared Banded Iron Formation (BIF). The shear is essentially contiguous along the upper contact of the BIF and an overlying mafc unit. There is some interpreted supergene mineralisation in the northern extents of the deposit that is controlled byweatheringhorizons and typicallycross cuts stratigraphyat shallow levels. |
| Dimensions | • The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan width, and depth below surface to the upper and lower limits of the Mineral Resource. |
• The Mt Henry mineralised domain is approximately 2km long and has a down dip extent of 280m and is open at depth. The deposit consists of a main lode that varies between 3m and 40m thick with numerousparallel lodes at various stages alongthe length of the deposit. |

| Estimation and modelling techniques |
• The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used. • The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data. • The assumptions made regarding recovery of by-products. • Estimation of deleterious elements or other non-grade variables of economic signifcance (e.g. sulphur for acid mine drainage characterisation). • In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed. • Any assumptions behind modelling of selective mining units. • Any assumptions about correlation between variables. • Description of how the geological interpretation was used to control the resource estimates. • Discussion of basis for using or not using grade cutting or capping. • The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available. |
• All modelling and estimation work undertaken by Metals X is carried out in three dimensions via Surpac Vision. • After validating the drillhole data to be used in the estimation, interpretation of the orebody is undertaken in sectional and / or plan view to create the outline strings which form the basis of the three dimensional orebody wireframe. Wireframing is then carried out using a combination of automated stitching algorithms and manual triangulation to create an accurate three dimensional representation of the sub-surface mineralised body. • Drillhole intersections within the mineralised body are defned; these intersections are then used to fag the appropriate sections of the drillhole database tables for compositing purposes. Drillholes are subsequently composited to allow for grade estimation. In all aspects of resource estimation the factual and interpreted geology was used to guide the development of the interpretation. • Once the sample data has been composited, a statistical analysis is undertaken to assist with determining estimation search parameters, top-cuts etc. Variographic analysis of individual domains is undertaken to assist with determining appropriate search parameters. Which are then incorporated with observed geological and geometrical features to determine the most appropriate search parameters. • An empty block model is then created for the area of interest. This model contains attributes set at background values for the various elements of interest as well as density, and various estimation parameters that are subsequently used to assist in resource categorisation. The block sizes used in the model will vary depending on orebody geometry, minimum mining units, estimation parameters and levels of informing data available. This is determined via QKNA in Snowden’s Supervisor v8.3. • Grade estimation was then undertaken, with the ordinary kriging estimation method considered as standard. There are no assumptions made about recovery. • The resource was then depleted for mining voids and subsequently classifed in line with JORC guidelines utilising a combination of various estimation derived parameters and geological / mining knowledge. • This approach has proven to be applicable to Metals X’s gold assets. • Estimation results are routinely validated against primary input data, previous estimates and miningoutput. |
| Moisture | • Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content. |

| Cut-of parameters | • The basis of the adopted cut-of grade(s) or quality parameters applied. |
• The mineralisation wireframes were modelled on a gold lower grade cut-of of 1.0 g/t Au. |
| This value was determined by visual assessment of grade continuity in Surpac. A geological model of the mineralised BIF unit was alsogenerated. |
||
| Mining factors or assumptions | • Assumptions made regarding possible mining methods, minimum mining dimensions and internal (or, if applicable, external) mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the mining assumptions made. |
• The Mt Henry deposit has been modelled under the assumption that it will be mined by conventional open pit mining methods, using excavators and trucks. Mineralisation wireframes were constructed based on minimum thickness of 2m downhole in order to replicate the smallest possible mining selectivity. |
| Metallurgical factors or assumptions |
• The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made. |
• No metallurgical assumptions have been made in respect to the generation of the estimate. |
| Environmental factors or assumptions |
• Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for a greenfelds project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made. |
• Metals X operates in accordance with all environmental conditions set down as conditions for grant of the respective mining leases. |
| Bulk density | • Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc.), moisture and diferences between rock and alteration zones within the deposit. • Discuss assumptions for bulk density estimates used in the evaluation process of the diferent materials. |
• A total of 2,501 bulk density (BD) determinations are recorded in the Mt Henry resource database subset. Panoramic completed most of these with measurements on 2,104 whole core samples by Archimedes water immersion method. There are a small number of historical measurements by pycnometer (7HENC115 & 7HENC116 for 54 samples) and down hole geophysical tool (NHC127, NHD120 and NHD121 for 343 one metre intervals). This data was used to generate a default SG for all lithological types. The default was then assigned to unmeasured intervals, and the density was estimated. • The host rock type for mineralisation and surrounding mafc material is non-porous and void space porosity is not considered to be of relevance to the measurements. • BD estimation for the resource was generated by grouping the 2,501 recorded measurements by rock type to provide an average SG for each of the main lithological rock types. The assay table in the database was tagged with the actual BD or an average value based on rock type grouped average. The BD value was then extracted with the Au grade in the 2m composite fle. The densities were estimated using the variogram models and search parameters for the various domains. |

These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fre assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems.

A small portion of the data used in resource calculations at the Central Musgrave Project (CMP) has been gathered from diamond core. This core is geologically logged prior to sampling. • RC Drilling RC drilling has been utilised extensively at the CMP. Drill cuttings are extracted from the RC return via cyclone. The underfow from each interval is transferred via bucket to a four tiered rife splitter, delivering approximately three kilograms of the recovered material into calico bags for analysis. The residual material is retained on the ground near the hole. Composite samples are obtained from the residue material for initial analysis, with the split samples remaining with the individual residual piles until required for re-split analysis or eventual disposal. • Historical A variety of drilling methods were employed by INCO, including churn drilling (102 holes) DDH (19 holes) RAB Drilling (2,643 holes) Vacuum (77 holes) Becker Drilling (102 holes). • Sample recovery from early drilling by INCO is not known. Sample recovery from RC drilling carried out from RC drilling after 2001 was generally very good, except where the drill hole encountered strong water fow from the hole. • All geology input is logged and validated by the relevant area geologists, incorporated into this is assessment of sample recovery. No defned relationship exists between sample recovery and grade. Nor has sample bias due to preferential loss or gain of fne or coarse material been noted. |

Samples were assayed for Ni, Co and Fe. Analytical quality control was maintained by the by the insertion of standard samples and re-analysis of duplicates at separate laboratories at a frequency of two check analyses for every twenty samples. • Composite samples of RC drilling completed in 2001 were submitted to AMDEL, dried and pulverised, and assayed for Ni, Co, Ag, As, Bi, Cu, Cr, Fe, Mg, Mn, Pb, S, Sb, Ti, V, Zr, Ca and Al by HF-multi-acid digest / ICP-OES. The 1m rife-splits for any composite sample assaying >0.4%Ni were retrieved, and re-assayed using the same method. • Composite samples from 2002-2004 were assayed for Al, Ca, Cr, Fe, Mg, Mn, Ni, Si, Ti by borate fusion ICP-OES, and for Ag, As, Bi, Co, Cu, Ni, Pb, S, Sb, V, Zr by HF-multi-acid digest / ICP-OES. • During 2005 two-metre composite rife-split (or spear-sampled for wet samples) samples were sent to SGS Laboratories in Perth. Each 2m composite sample was dried and pulverised to a nominal 90 per cent passing 75 microns and analysed for: As, Bi, Co, Cu, Ni, Pb, S and Zn by ICP-OES.

This measured X, Y and Z to sub-centimetre accuracy in terms of the MGA 94, Zone 52 metric grid. • Hole collars for almost all INCO drill holes were re-located, and surveyed in using the TREK GPS. Several INCO collars could not be located, and their MGA positions are estimated from their drilled location on the original INCO Imperial local grid. • Topographic control is generated from a combination of remote sensing methods and ground- based surveys. This methodologyis adequate for the resource inquestion. |
| Data spacing and distribution | • Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufcient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifcations applied. • Whether sample compositing has been applied. |
• Drill hole spacing at CMP is generally on a 120m x 50m spacing. This has been flled-in to 60 x 50 and 30m x 25m spacing in some areas. The data spacing is sufcient for both the estimation procedure and resource classifcation applied. • Compositing of drill assay data to 2m was used in the estimate. |
| Orientation of data in relation to geological structure |
• Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
• Drilling intersections are nominally designed to be sub-normal to the orebody. • It is not considered that drilling orientation has introduced an appreciable sampling bias. |
| Sample security | • The measures taken to ensure sample security. |
• Samples are delivered to a third party transport service, who in turn relay them to the independent laboratorycontractor. Samples are stored securelyuntil theyleave site. |
| Audits or reviews | • The results of any audits or reviews of sampling techniques and data |
• Site generated resources and reserves and the parent geological data is routinely reviewed bythe Metals X Corporate technical team. |

| Database integrity Site visits |
• Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. • Data validation procedures used. • Comment on any site visits undertaken by the Competent Person and the outcome of those visits. • If no site visits have been undertaken indicate why this is the case. |
• Drillhole data is stored in a Maxwell’s DataShed system based on the Sequel Server platform which is currently considered “industry standard”. • As new data is acquired it passes through a validation approval system designed to pick up any signifcant errors before the information is loaded into the master database. The information is uploaded by a series of Sequel routines and is performed as required. The database contains diamond drilling (including geotechnical and specifc gravity data), and some associated metadata. By its nature this database is large in size, and therefore exports from the main database are undertaken (with or without the application of spatial and various other flters) to create a database of workable size, preserve a snapshot of the database at the time of orebody modelling and interpretation and preserve the integrity of the master database. • The site is manned continually by Senior Geological personnel. • The Competent Person has undertaken site visits in the recent past. |
| Geological interpretation | • Confdence in (or conversely, the uncertainty of ) the geological interpretation of the mineral deposit. • Nature of the data used and of any assumptions made. • The efect, if any, of alternative interpretations on Mineral Resource estimation. • The use of geology in guiding and controlling Mineral Resource estimation. • The factors afecting continuity both of grade and geology. |
• Confdence in the geological model used to constrain the Wingellina estimate is high, with the genetic model for lateritic nickel development well understood. Logged geology has been used to drive the mineralisation interpretation, with the base of laterite defned with drill holes, or its level on a given section interpreted from surrounding drill sections. Continuity of the interpretation across and along the Wingellina deposit is for the most part good, with intersections of hard rock in drill holes, and well mapped outcropping basement the primary causes of breaks within the mineralised horizon. • No alternative interpretations are currently considered viable. • Geological interpretation of the deposit was carried out using a systematic approach to ensure that the resultant estimated Mineral Resource fgure was both sufciently constrained, and representative of the expected sub-surface conditions. In all aspects of resource estimation the factual and interpreted geology was used to guide the development of the interpretation. • The protolithology is the dominant control on grade continuity at the CMP. Structural controls which infuence depth of weatheringare secondarycontrols ongrade distribution. |
| Dimensions | • The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan width, and depth below surface to the upper and lower limits of the Mineral Resource. |
• Individual deposit scales vary across the CMP. • The Wingellina deposits have a strike length of >9km, a lateral extent of up to 2.5km and a depth of upto 200m. |

| Estimation and modelling techniques |
• The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used. • The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data. • The assumptions made regarding recovery of by-products. • Estimation of deleterious elements or other non-grade variables of economic signifcance (e.g. sulphur for acid mine drainage characterisation). • In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed. • Any assumptions behind modelling of selective mining units. • Any assumptions about correlation between variables. • Description of how the geological interpretation was used to control the resource estimates. • Discussion of basis for using or not using grade cutting or capping. • The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available. |
• All modelling and estimation work undertaken was carried out in three dimensions via Micromine or Surpac Vision. • After validating the drill hole data to be used in the estimation, interpretation of the orebody is undertaken in sectional and / or plan view to create the outline strings which form the basis of the three dimensional orebody wireframe. Wireframing is then carried out using a combination of automated stitching algorithms and manual triangulation to create an accurate three dimensional representation of the sub-surface mineralised body. • Drillhole intersections within the mineralised body are defned, these intersections are then used to fag the appropriate sections of the drill hole database tables for compositing purposes. Drill holes are subsequently composited to allow for grade estimation. In all aspects of resource estimation the factual and interpreted geology was used to guide the development of the interpretation. • Once the sample data has been composited, a statistical analysis (using Snowden Supervisor v8.5) is undertaken to assist with determining estimation search parameters, top-cuts etc. Variographic analysis of individual domains is undertaken to assist with determining appropriate search parameters. Which are then incorporated with observed geological and geometrical features to determine the most appropriate search parameters. • An empty block model is then created for the area of interest. This model contains attributes set at background values for the various elements of interest as well as density, and various estimation parameters that are subsequently used to assist in resource categorisation. The block sizes used in the model will vary depending on orebody geometry, minimum mining units, estimation parameters and levels of informing data available. • Grade estimation is then undertaken, with the ordinary kriging estimation method considered as standard, although in some circumstances where sample populations are small, or domains are unable to be accurately defned, inverse distance weighting estimation techniques may be used. Both by-product and deleterious elements are estimated at the time of primary grade estimation if required. It is assumed that by-products correlate well with Nickel. There are no assumptions made about the recovery of by-products. • The resource is then depleted for mining voids and subsequently classifed in line with JORC guidelines utilising a combination of various estimation derived parameters and geological / mining knowledge. • This approach has proven to be applicable to Metals X’s nickel assets. • Estimation results are routinely validated against primary input data, previous estimates and miningoutput. |
| Moisture | • Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content. |

It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made. |
• Not considered for Mineral Resource. Applied during the Reserve generation process. |
| Environmental factors or assumptions |
• Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for a greenfelds project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made. |
• MLX operates in accordance with all environmental conditions set down as conditions for grant of the respective leases. |
| Bulk density | • Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc.), moisture and diferences between rock and alteration zones within the deposit. • Discuss assumptions for bulk density estimates used in the evaluation process of the diferent materials. |
• Sampling of HQ diamond drill core was used to determine the dry density of laterite ore. Average measured dry density is 1.23t/m3 for limonite ore and 1.40t/m3 saprolite ore. • A total of 281 triple-tube HQ core samples were collected immediately from the core barrel and measured for bulk density on site. The core length was measured for diameter and length (square-cut ends), dried for 24 hours in a gas oven at 120C, and weighed. • Density was calculated by dividing the weight (kg) of dry sample by the volume of the core piece. |
| Classifcation | • The basis for the classifcation of the Mineral Resources into varying confdence categories. • Whether appropriate account has been taken of all relevant factors (i.e. relative confdence in tonnage/grade estimations, reliability of input data, confdence in continuity of geology and metal values, quality, quantity and distribution of the data). • Whether the result appropriatelyrefects the Competent Person’s view of the deposit. |
• Resources are classifed in line with JORC guidelines utilising a combination of various estimation derived parameters, the input data and geological / mining knowledge. • This approach considers all relevant factors and refects the Competent Person’s view of the deposit. |

The underfow from each interval is transferred via bucket to a four tiered rife splitter, delivering approximately three kilograms of the recovered material into calico bags for analysis. The residual material is retained on the ground near the hole. Composite samples are obtained from the residue material for initial analysis, with the split samples remaining with the individual residual piles until required for re-split analysis or eventual disposal. • In the case of grade control drilling, 1m intervals were split at the rig via a 3-tier splitter box below the cyclone and collected in calico bags with bulk samples collected into large plastic bags. These 1m splits were dried, pulverised and split to produce a 50g charge for fre assay at an ofsite laboratory. • Where composite intervals returned results >0.15g/t Au, the original bulk samples were split by 3-tier rife splitter to approximately 3-4kg. The whole sample was dried, pulverised and split to produce a 50g charge for fre assay at an ofsite laboratory. • Historic diamond drilling sampled according to mineralisation and lithology resulting in samples of 10cm to 1.5m. Half core pulverised and split to produce a 50g charge for fre assay at an ofsite laboratory. |

| Drilling techniques | • Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
• All reverse circulation at nominal 5.5” diameter, utilising face sampling hammers to reduce the risk of sample contamination. • Diamond drilling utilised 10-40m RC pre-collars to penetrate transported cover then continued as NQ core. Core was oriented bydown-hole spear. |

• Reverse circulation recorded sample quality, recovery and moisture for 1m samples. The majority of samples were of good quality with ground water having minimal efect on sample quality or recovery. Statistical analysis of sample quality for samples over an Au bottom cut of 0.1ppm indicates negligible sample bias. • Diamond drilling recorded rock hardness, recovery and RQD. Core recovery was good. |
| Logging | • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. • The total length andpercentage of the relevant intersections logged. |
• Reverse circulation chips were washed and stored in chip trays in 1m intervals. Chips were visually inspected, recording lithology, weathering, alteration, mineralisation, veining and structure. • Diamond core was visually inspected, recording data related to lithology, weathering, alteration, mineralisation, veining and structure. Photographs of each core tray were taken wet. • All mineralised intersections from both diamond core and reverse circulation were logged. |

• The grid system used for historic Fortnum drilling is the established Fortnum Mine Grid. Control station locations and traverses have been verifed by eternal survey consultants (Ensurv). Collar locations of boreholes have been established by either total station or diferential GPS (DGPS). The Yarlarweelor, Callie’s and Eldorado open pits (currently abandoned) was picked up by DGPS at the conclusion of mining. The transformation between Mine Grid and MGA94 Zone 50 is documented and well established. • A LIDAR survey over the project area was undertaken in 2012 and results are in agreement with survey pickups of pits, low-grade stockpiles and waste dumps. • Historic drilling by Homestake was routinely surveyed at 25m, 50m and every 50m thereafter, using a single shot CAMTEQ survey tool. RC holes have a nominal setup azimuth applied. Perilya YLRC series holes had survey shots taken by Gyro every 10m. Historic drilling in the area did not appear to have any signifcant problems with hole deviation. • Drilling by RNI / MLX was picked up by DGPS on MGA94. Down hole surveys were taken by digital single shot camera every50m or via agyro surveytool. |

oSheeted and stockwork quartz-pyrite veins associated with brittle deformation of the jasperoid lithologies. The mineralisation is hosted within quartz vein stockworks and sheeted vein arrays proximal to or within brecciated zones within jasperoid units. Quartz veins hold minimal internal grade, with the majority of mineralisation associated with coarse grained disseminated euhedral pyrite along the vein selvages and within zones of strong silicifcation. Jasperoid bodies are host to the majority of mineralisation are bounded within the intensely foliated, west-northwest dipping, east-northeast striking shear zones. These bodies are strongly folded on a macro scale with a pronounced moderate southwesterly plunge. oStructurally controlled stockwork veins within volcaniclastics. The structurally controlled vein stockworks occur in the footwall of major thrust faults and located within intermediate tufs and tufaceous siltstones. Gold mineralisation is associated with zones of pyritisation, silicifcation, albitisation or sericitisation in quartz vein selvedges. oSupergene associated mineralisation. • Low-grade stockpiles are derived from previous mining of the mineralisation styles outlined above. • Geological matrixes were established to assist with interpretation and construction of the estimation domains. • Confdence in the interpretation is high as the geometry, geology, alteration and tenor of the mineralised zones was observed to be consistent along strike and down dip • The interpretations was based on 10m and 20m north-south spaced sections. • The information used in the construction and estimation of the respective resources mineralisation is based on Air Core (AC), Reverse Circulation (RC) and Diamond Drill (DDH) hole information. The AC was included in the poorly information estimation domains and this was considered during the classifcation of these domains. • Oxidation surfaces were constructed from the logged information on 20m north south sections. |

• The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used. • The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data. • The assumptions made regarding recovery of by- products. • Estimation of deleterious elements or other non-grade variables of economic signifcance (e.g. sulphur for acid mine drainage characterisation). • In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed. • Any assumptions behind modelling of selective mining units. • Any assumptions about correlation between variables. • Description of how the geological interpretation was used to control the resource estimates. • Discussion of basis for using or not using grade cutting or capping. • The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available. |
• All modelling and estimation work undertaken by Metals X is carried out in three dimensions with Surpac Vision, Snowden’s Supervisor v8.3 and or Isatis 2015. • Ordinary kriging (OK) and Localised Indicator Kriging (LIK) has been used for the estimation of the Yarlarweelor and Callies’ mineralisation. LIK was used for the estimation of all Jasperoid related estimation domains due to mosaic mineralisation style. Ordinary kriging only was used for Eldorado. Length weighting of assay values related to surveyed volumes was undertaken for low-grade stockpiles. • All estimates were validated where possible against historical production records and previous estimates. • After validating the drillhole data to be used in the estimation, interpretation of the orebody is undertaken in sectional and / or plan view to create the outline strings which form the basis of the three dimensional orebody wireframe. Wireframing was carried out using a combination of automated stitching algorithms and manual triangulation to create an accurate three dimensional representation of the sub-surface mineralised body. Domaining was constructed on 20m and 10m spaced sections and was based on logged lithologies, quartz percentage and gold value. • Drillhole intersections within the mineralised body are defned; these intersections are then used to fag the appropriate sections of the drillhole database tables for compositing purposes. Assay data was composited to 1m downhole using Surpac “best ft” algorithm. The “best ft” algorithm eliminates residual composites and the estimation domains boundaries defned the start and end position of the compositing routine. In all aspects of resource estimation; the factual and interpreted geology was used to guide the development of the interpretation. • Support analysis of the diference drill types (Air Core (AC), Reverse Circulation (RC) and Diamond Drill holes (DDH)) was performed and the mixing these deemed acceptable. The AC drill holes were used in the estimation of the poorly informed estimation domains. • Statistical analysis was carried out on the composited data to assist with determining estimation search parameters, top-cuts and spatial continuity. Data for some of the domains exhibit an increased degree of skewness and top cuts were applied to reduce the skewness of distribution. The appropriateness of the top cuts was assessed for each domain utilising log-probability plots, mean and variance plots, histograms and univariate statistics for the composite Au variable. • Variogram modelling was undertaken using Isatis™ software and defned the spatial continuity of gold within all domains and these parameters were used for the interpolation process. Indicator variograms were generated within the Jasperoid related estimation domains to the used in the LIK estimation process. • Volume models were generated in Surpac using topographic surfaces, oxidation surfaces and mineralised zone wireframes as constraints. • Quantitative Kriging Neighbourhood Analysis was used optimise the search parameters. • Search ellipses were aligned parallel to the maximum continuity defned during the variographic analysis. The search dimensions, generally, approximated the ranges of the interpreted variograms and ranged from 50 to 100m. The minimum and maximum number of samples range from 7 to 11 and 18 to 30, respectively. Second and third pass searches were implement to fll the un-estimated cells / blocks if they were not estimated during the frst search pass and these search parameters involved increasing in the search distances and reducing in the minimum number of samples used in the estimation process. • The extrapolation was control through the interpreted estimation domains, which was limited to half the drill hole spacing within section and half the section spacing between sections. • Block estimation for gold was undertaken using Isatis™ and hard boundaries were used between domains for estimation of gold grade. • No assumptions were made about recovery during the OK and LIK estimation processes. • Grade estimation was undertaken, with the ordinary kriging (OK) estimation method for all non-jasperoid related estimation domains. • Check estimates were run using Localised Uniform Conditioning (LUC) for the LIK estimation domains, which produces a similar form of result to LIK. The LIK and LUC models were compared, with reasonable agreement at lower cut-ofs and diferences at higher cut-ofs refecting higher estimated gold variability in the LIK model. The LIK is believed to be better suited to the style of mineralisation for the Jasperoid related estimation domains and has been favoured for ofcial reporting of the Mineral Resources.

• Horizons were modelled based on oxidation state of the host rocks, taken from the drilling information. These were: Transported and lateritic residuum, oxidised, transitional and fresh. • Jasperoid was fagged in the model due to it’s hardness and difering heap leach characteristics as identifed in recent metallurgical scoping studies. |

| Environmental factors or assumptions |
• Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for a greenfelds project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made. |
• Metals X operates in accordance with all environmental conditions set down as conditions for grant of the respective mining leases. |
| Bulk density | • .Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc.), moisture and diferences between rock and alteration zones within the deposit. • Discuss assumptions for bulk density estimates used in the evaluationprocess of the diferent materials. |
• A total of 432 bulk density determinations were collected within the Yarlarweelor mineralised area. The bulk densities were separated into diferent weathering domains and lithological domains (i.e. jasperoid domains). Density determinations were made on diamond drill core representing mineralisation utilised the water immersion method (Archimedes Principle) • The assigned bulk densities were: transported 1.90 t/m3, oxide 2.00 t/m3, oxide Jasperoid 2.50 t/m3, transitional 2.20 t/m3, transitional Jasperoid 2.20 t/m3, fresh 2.70 t/m3and fresh Jasperoid 2.70 t t/m3. |
| Classifcation | • The basis for the classifcation of the Mineral Resources into varying confdence categories. • Whether appropriate account has been taken of all relevant factors (i.e. relative confdence in tonnage/ grade estimations, reliability of input data, confdence in continuity of geology and metal values, quality, quantity and distribution of the data). • Whether the result appropriately refects the Competent Person’s view of the deposit. |
• The continuity of geology and mineralisation is well understood, with most of the reported resource being covered by either 20 x2 0m resource drilling or 10 x1 0m grade control drilling. • The non-linear, local estimation method used is considered appropriate for the style of mineralisation and assumed mining selectivity. • A combination of gold estimation quality parameters and drill spacing were ultimately used to defne resource confdence categories. • The Competent Person believes that the classifcation fairly represents the confdence in the resource estimates, as they are described in the JORC (2012) code. |
| Audits or reviews | • The results of any audits or reviews of Mineral Resource estimates. |
• Resource estimates are peer reviewed by the site technical team as well as Metals X’s Corporate technical team. |

| Discussion of relative accuracy/ confdence |
• Where appropriate a statement of the relative accuracy and confdence level in the Mineral Resource estimate using an approach or procedure deemed appropriate by the Competent Person. For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the resource within stated confdence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors that could afect the relative accuracy and confdence of the estimate. • The statement should specify whether it relates to global or local estimates, and, if local, state the relevant tonnages, which should be relevant to technical and economic evaluation. Documentation should include assumptions made and the procedures used. • These statements of relative accuracy and confdence of the estimate should be compared with production data, where available. |
• Mineral Resources have been reported in accordance with the guidelines of the 2012 edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves and refects the relative accuracy of the Mineral Resource estimates. • The current Mineral Resource model represents a robust estimate of the in-situ gold mineralisation for Fortnum resource reported. The method used is designed to provide an estimate of local mineable resources, based on current mining methods. |

| Mineral Resource estimate for conversion to Ore Reserves |
• Description of the Mineral Resource estimate used as a basis for the conversion to anOre Reserve. • Clear statement as to whether the Mineral Resources are reported additional to, or inclusive of, the Ore Reserves. |
• The total Reserve Statement of 174k Oz is a combination of the individual ‘Resource’ models, as 31st March 2016, with the appropriate mining, geotechnical, processing and hydrological modifying factors applied. • The total Resource for Measured and Indicated categories is 7,918k tonnes @ 1.5 g/t for 388k contained Ounces (based on cut-ofs specifc to the individual orebodies). The Mineral Resources are inclusive of Ore Reserves. • All resources that have been converted to Reserve are classifed as either Indicated or Measured. Indicated Resources are only upgraded to Probable Reserves after adding appropriate modifying factors. Some Measured Resource may be classifed as Proven Reserves and some are classifed as Probable Reserve based on whether it is developed and /or has drill hole density/ historicalproduction. |
| Site visits | • Comment on any site visits undertaken by the Competent Person and the outcome ofthose visits. • Ifno site visits have been undertaken indicate why this is the case. |
• Mr Anthony Buckingham has been an employee of Metals X (and its subsidiaries) for the past 7 years and has over 15 years’ experience specifcally in the Western Australian mining industry. Mr Buckingham visits the Fortnum mine site on a regular fortnightly basis and is the primary engineer involved in mineplanning, site infrastructure andproject management. |

| Study status | • The type and level of study undertaken to enable Mineral Resources to beconverted to Ore Reserves. • The Code requires that a study to at least Pre-Feasibility Study level has beenundertaken to convert Mineral Resources to Ore Reserves. Such studies will have been carried out and will have determined a mine plan that is technically achievable and economically viable, and that material Modifying Factors have been considered. |
• The Fortnum Gold Mine Operation ceased production in May 2007 when owned by Gleneagle Gold. Previous to this the operation was operated by Perilya and Homestake, and frst began commercial mining operations in the late 1980’s. Extensive mining and processing records are therefore available in each of the deposits. • Various open pit styles and host domains have been mined since discovery of the area by Homestake in 1980’s. Mining during this time has ranged from open pit cut backs, virgin surface excavations to extensional underground developments. • The Fortnum Gold Mine Open Pit inventory had a Pre-feasibility study completed by MLX in early 2016. Additional details and a revision of the Resources (with classifcation) have continued since this initial fnancial evaluation. The Fortnum Gold Mine is therefore now at a budgetary level analysis with specifc details on processing components and reagent costs, specifc mining contractor cost profles as well as site specifc G&A. |
| Cut-of parameters | • The basis of the cut-of grade(s) or quality parameters applied. |
• The pit rim cut of grade (COG) was determined as part of the Reserve estimation. The pit rim COG determines which material will be processed by equating the operating cost of processing, surface haulage, G&A and selling cost to the value of the mining block in terms of recovered metal and the expected selling price. The COG is then used to determine whether or not a mining block should be delivered to the treatment plant for processing or taken to the waste dump as waste. • A COG of 0.9g/t was applied to the Reserve open pit inventory, with local Low grade piles having a 0.6g/t determinant and the regional low grade stocks of Horseshoe being cut at 0.8g/t. • Low Grade stockpiles incurred a low cost profle than open pits for processing, because of the predominantly oxide material, as well as G&A, as the operation would have limited fxed management when millingthis inventory. |

| Mining factors or assumptions |
• The method and assumptions used as reported in the Pre-Feasibility or FeasibilityStudy to convert the Mineral Resource to an Ore Reserve (i.e. either by application of appropriate factors by optimisation or by preliminary or detailed design). • The choice, nature and appropriateness of the selected mining method(s) and other mining parameters including associated design issues such as pre-strip, access, etc. • The assumptions made regarding geotechnical parameters (e.g. pit slopes, stope sizes, etc.), grade control and pre-production drilling. • The major assumptions made and Mineral Resource model used for pit and stope optimisation (if appropriate). • The mining dilution factors used. • The mining recovery factors used. • Any minimum mining widths used. • The manner in which Inferred Mineral Resources are utilised in mining studies andthe sensitivity of the outcome to their inclusion. • The infrastructure requirements of the selected mining methods. |
Following consideration of the various modifying factors the following rules were applied to the reserve estimation process for the conversion of measured and indicated resource to reserve for suitable evaluation. • The mining shape in the reserve estimation is generated by a wireframe (geology interpretation of the ore zone) which overlays the block model. Where the wire frame cuts the primary block, sub blocks fll out the remaining space to the wire frame boundary (efectively the mining shape). It is reasonable to assume that the mining method can selectively mine to the wire frame boundary with the additional dilution provision stated in point 2 below. • Ore Reserves are based on Pit shape designs – with appropriate modifcations to the original Whittle Shell outlines to ensure compliance with practical mining parameters. • Geotechnical parameters allied to the Open Pit Reserves are either based on observed existing pit shape specifcs or domain specifc expectations / assumptions. Various geotechnical reports and retrospective reconciliations were considered in the 2016 design parameters. A majority of the open pits have a fnal design wall angle of 38-420, which is seen as conservative. • Dilution of the ore through the mining process has been set at 15% which is considered as additional ore mined in relation to mining to the wire frame boundary as identifed in point 1 above, albeit at a grade of 0.0 g/t. The amount of dilution is considered appropriate based on orebody geometry, historical mining performance and the size of mining equipment to be used to extract ore. • Expected mining recovery of the ore has been set at 95%. • Minimum Mining widths have been accounted for in the designs, with the utilization of 90T trucking parameters. • No specifc ground support requirements are needed outside of suitable pit slope design criteria based on specifc geotechnical domains. • Mining sequence is included in the mine scheduling process for determining the economic evaluation and takes into account available operating time and mining equipment size and performance. • NoInferredmaterial is included within the open pit statement, though in various pit shapes inferred material ispresent. In these situations this inferred material is classifed as waste. |
| Metallurgical factors or assumptions |
• The metallurgical process proposed and the appropriateness of that process to the style of mineralisation. • Whether the metallurgical process is well-tested technology or novel in nature. • The nature, amount and representativeness of metallurgical test work undertaken, the nature of the metallurgical domaining applied and the corresponding metallurgical recovery factors applied. • Any assumptions or allowances made for deleterious elements. • The existence of any bulk sample or pilot scale test work and the degree to whichsuch samples are considered representative of the orebody as a whole. • For minerals that are defned by a specifcation, has the ore reserve estimation been based on the appropriate mineralogy to meet the specifcations? |
• Fortnum Gold Mine has an existing conventional CIL processing plant – which has been operational in various periods since the late 1980’s. The plant has anameplatecapacity of 1.0Mtpa though this can be varied between 0.8-1.2Mtpa pending rosters and material type. • Grindsize for the sulphide material has historically been 130 µm. • An extensive database of historical CIL recoveries as well as detailed metallurgicaltestwork is available for the various deposits and these have been incorporated into the COG analysis and fnancial models. • For the 2016 Reserve, Plant recoveries of 93-95% have been utilised. |
