DUE TO TYPOGRAPHICAL ERROR IN THE DRILLING RESULTS TABLE ON PAGE 4 THE RESULTS FOR HOLE UHC 106 SHOULD READ AS FOLLOWS:
| Hole ID | From | To | Drill Intersection | Fe | V205 | TiO2 |
|---|---|---|---|---|---|---|
| M | M | M | % | % | % | |
| UHC 106 | 67 | 85 | 18 | 28.1 | 0.52 | 7.68 |

HIGH GRADE DRILL RESULTS IRON ORE AND VANADIUM
MID-WEST IRON ORE PROVINCE WESTERN AUSTRALIA
HIGHLIGHTS
Wide drill intersections up to:-
- 50m @ 37.8% Fe 0.72% V2O5 - 10.01% Ti O2
- 5.5 kilometres of drill tested mineralisation identified.
- Further 7.5 kilometres of the same aeromagnetic structure yet to be tested.
- Confirmed mineralisation open both along strike and to a vertical depth of 300 metres.
- Excellent benefication characteristics to produce high grade iron – vanadium concentrate.
UNALY HILL PROJECT (E57/420) (100%)
- LOCATION AND INFRASTRUCTURE
- Unaly Hill project is located in the Mid-West iron ore province 50 kilometres South of Sandstone, East Murchison Mineral Field, Western Australia. The project is favourably located within the emerging Mid-West, where Oakajee Port and rail (OPR) are reaching completion of their rail and port project that will service the region's mining needs.
Other mining companies also in the area (refer image below):
ATLANTIC LIMITED
Atlantic's Windimurra project located 30 km to the west is scheduled to recommence production in 2011, based on a JORC reserve of 97Mt. grading 0.47% V2O5.
Unaly Hill's Vanadium grades compare very favourably to that at Windimurra with the project further benefitting from, at or near surface mineralisation. Also of note is the fact that Windimurra is connected to the Dampier- Bunbury gas pipeline that reasonably could be expected to provide a similar power source to Unaly Hill.

DRILLING RESULTS
Black Ridge's completed drilling programme comprised 13 Reverse Circulation holes for a total of 2066 metres (Refer Figure 2 next page). Drilling was designed primarily to test both the continuity and grade of magnetite and vanadium mineralisation present within a major north-south-trending magnetic anomaly detected from the interpretation and 3D modelling of detailed airborne magnetic surveys.

The holes drilled at a dip of -60o and azimuth of 110o except UHN 105 290o azimuth.
To date, this major anomaly has been traced over a strike length of some 14 kilometres of which at least 11 kilometres fall within Black Ridge's E57/420. Some 7.5 kilometres of this anomaly still remains to be tested.

FOUR CORNERS WELL (E57/760)
E57/760 is adjacent to and south of Black Ridge's E57/420 covering some 2 kilometres of the same mineralised magnetic structure. Black Ridge has the option to earn 60% interest with Meteoric Resource NL ( ASX: MEI ) to carry out drill investigation of this tenement.
To date 5 holes UHS 01 – UHS 05 have been drilled for a total of 850 metres confirming the presence of iron and vanadium mineralisation (Table 2).
