More High Grade Hits at Matilda

Sydney, Mar 12, 2012 AEST (ABN Newswire) - Blackham Resources Ltd (ASX Code: BLK) is pleased to announce further results of drilling at the Matilda Gold Project, completed in late February. Results from 12 holes, all located at the M10 Prospect, have now been returned and include additional high-grade intercepts:

7m @ 14.0 g/t Au from 74m (MARC0009);
16m @ 4.50 g/t Au from 34m (MARC0001); and
7m @ 3.48 g/t Au from 14m (MARC0001).

Full results can be found in the link at the end of this announcement.

These new results not only support the early results from the programme, but have also extended the mineralisation up-plunge to only 12 vertical metres below surface. The result of 7m @3.48 g/t in MARC0001 is the shallowest economic mineralisation intersected at the M10 Prospect to date and should have a positive impact on open-pit mining economics.

Further, mineralisation remains open to the south as potentially shallow supergene mineralisation and quartz-vein mineralisation. The position of the main shoot where it is projected to intersect the surface is yet to be tested, providing encouragement for additional resource increases (See Link).

Mineralisation is now recognized in four discrete zones (See Link):

Laterite Mineralisation: Just beneath the surface, the laterite mineralisation is generally low-grade but was successfully mined from other Matilda Deposits and treated via heap leach methods.

Upper and Lower Supergene Mineralisation: The weathering profile at M10 is extremely deep, extending below 100 vertical metres. Within the weathered zone are at least two supergene enriched zones extending laterally above the primary mineralisation.

Quartz vein-hosted lodes: Primary mineralisation occurring in quartz veins with shoot geometries (sometimes observed as saddle reefs), plunging at shallow angles to the north. This geometry is consistent with other deposits at the Matilda Mining Centre.

Interpretation of the results is continuing. Additional results are expected in the coming weeks, including drill holes from other Matilda prospects and will be released to market as they come to hand.

Background
Blackham acquired the Matilda Gold Project in November 2011, including the Matilda and Williamson Gold Mines and numerous other deposits and prospects. The project covers over 600km2 surrounding the operating Wiluna Gold Mine owned by Apex Minerals NL. This region has produced over 4 million ounces of gold. The current Wiluna Gold Mine resource is 12.7 Mt at 5.4g/t gold (as reported by Apex Minerals NL in their 2011 Annual Report).

The Matilda Mining Centre is located approximately 19km south of the township of Wiluna and produced 265,000oz prior to its closure in 1992. Blackham has validated 601,000oz of remaining resources at the Project, which has good potential for additional discoveries.

Matilda Mining Centre
The Matilda Mining Centre was last exploited by ASARCO during the early-90's, comprising 7 shallow open pits. Most of these pits were mined to less than 50m and have significant mineralisation outside the pit limits. It is a large mineralised system with gold hosted in saddle reef and shear structures often with near surface supergene enrichment.

Blackham management are pleased with the continuing return of positive drill results which have confirmed the potential for high grade ore at shallow depths at the Matilda Mining Centre.
