Dragon Energy Limited (“Dragon”, ASX: DLE ) is pleased to announce that its Channel Iron Mineralisation (‘CIM’) Resources at its Rocklea Project in the Pilbara, Western Australia, have increased to 93.59Mt grading 52.19% Fe (59.16% caFe) (Figure 2).
The updated Resource model was prepared by Golder Associates Pty Ltd and has achieved Dragon’s main objective of an improved resource category with 84% of the JORC Resource now in the Indicated category. The increased Resource will offer potentially significant cost efficiencies and substantially greater ability to pursue the development of the Rocklea Project.

MINERAL RESOURCE
The mineral resource update is based on data from RC drilling completed between 2005 to 2009, and infill drilling from 2011-2012. For the Main mineralisation drill holes are spaced 50m along sections approximately 200m apart, and for the North Pod drilling is spaced on a 200x200m grid testing outcropping CID mineralisation (see Figure 3).
The main purpose of the infill drilling campaign was to improve the resource category of the Rocklea deposit in preparation for advanced mine planning and project development. This has now been achieved with over 84% of the updated Resource now in the Indicated category.
The updated resource estimate is summarised below using cut-off grades of 45%, 50% and 53% Fe:

Table 1: Rocklea JORC Resources
As announced on 10 July 2012, Dragon has signed an agreement to acquire Murchison Metals Ltd’s (“Murchison”) Pilbara project, subject to the parties obtaining consent to the assignment of a standard heritage agreement. The Murchison project is located adjacent to Dragon’s existing Rocklea tenement E47/1024-I and includes P47/1429-I, the iron ore rights to E47/1153-I which is held by Joytell Pty Ltd, and E47/952-I which contains the southern extension of the Rocklea deposit CIM with a JORC Mineral Resource of 89Mt @ 53.2% Fe (59.9% caFe) (Figure 1). This consolidation will substantially increase Dragon’s iron ore Mineral Resource at the Rocklea Project to a total Resource of 182.6Mt @ 52.7% Fe (59.5% caFe) with a 50% cut-off grade (Table 2).
1 The Mineral Resource was updated in 2012 in accordance with the guidelines of the Australasian Code for reporting Exploration Results, Mineral Resources and Ore reserves (JORC Code 2004) using a 45% lower cut-off grade, and a specific gravity of 2.7. No mining parameters were applied to the model.

Dragon’s Managing Director, Gang Xu, stated that the updated Resource was an important step in the development of the company’s Pilbara Iron Ore Project.
“We are very pleased with the results of this new Resource model. Not only have we achieved our main objective by bringing the majority of the Resource to an Indicated level but we have also added over 30 million tonnes to our total iron ore Resources at a 50% iron cut-off grade.”
“The results at the 45% cut-off grade are also extremely encouraging with only a slightly lower average iron grade, compared to the 50% cut-off. It is likely that the project is viable at a 45% cut-off and this gives us 117.06 million tonnes grading 51.65% iron, or a calcined iron content of 58.60%.”
“Our maiden Resource for the Nameless Project is close to completion and when we combine that with our consolidated Rocklea project, we will have a large scale Resource to pursue our company objectives.”
There is further exploration potential to increase Dragon’s iron ore Resources in the Pilbara region with possible new exploration targets within the tenements of the Murchison Rocklea Project as well as the western end of the Nameless tenement.
FUTURE PLAN
Continued development of the Pilbara Iron Ore Project:
-
Complete maiden Resource model for Nameless Project.
-
Identifying and securing approvals for an export port suited to road transportation;
-
Undertake formal pre-feasibility study for the consolidated Pilbara Iron Ore Project combining the updated Rocklea and Nameless project Resources with the soon to be acquired Murchison Metals Ltd Rocklea Iron Project assets;
-
Launch and complete long lead time approval items, i.e. environmental studies, heritage agreements, mining lease approvals;
-
Identify new exploration targets for testing within exploration licences to be acquired from Murchison Metals Ltd to further grow Dragon’s iron ore resources in the Pilbara region; and
-
Identifying and securing financing for project development.
