mumbwa - GOLD/COPPER PROJECT
Interpretation of BHPB’s Falcon™ data with 3D inversions and the application of BHPB’s Solid Earth™ proprietary technology identified anomalous zones over the Kitumba Hills, Worm and Mutoya prospects;
Initial 8 hole core drilling program totalling 4,105.17m was completed in February 2007;
A major drilling will commence late January 2008. The Company has engaged three drilling rigs to complete 20 cored holes for a total of approximately 10,200 metres.
Hole, S36-001, was drilled to a total depth of 697.4m, and intersected mineralisation yielding 655m at 0.46% copper, including:
317m @ 0.79% Cu,
18m @ 0.20g/t Au,
42m @ 2.01% Cu, including
4m @ 5.56% Cu.
Soil geochemical survey over drilled anomalies displayed elevated gold response over S36;
MOKOPANE - NICKEL/PLATINUM PROJECT
Nickel-Platinum project located on the Northern limb of the Bushveld Complex;
Granted new order rightsover 3,000 hectares for exploration purposes;
Appointment of Black Economic Empowerment (BEE) party;
JORC compliant Inferred Resource of 39.7 million tonnes at 0.146% nickel, 0.085% copper, 0.22 g/t platinum and 0.33g/t palladium;
Near surface mineralisation is amenable to low cost, large scale, open pit mining with low strip ratio;
Significant potential to increase current resource by additional drilling from all 5 prospects within the licence area;
Considering a percussion drilling program to further define the resource status from all 5 prospects.
