Blackthorn Resources (ASX: BTR) is poised to undertake an extensive exploration program at the Mumbwa Project in Zambia, with a 7000 metre drilling campaign targeting a boost in confidence levels in the existing resource.
Drill rigs are on site to undertake the core drilling of 14 holes over the Kitumba deposit, with drilling to continue through to the end of the year.
First assays are expected in the December quarter of 2011.
Highlighting the prospectivity of the project, the new drilling will infill in proximity to the substantial 2008 hit of; 401 metres at a weighted grade of 0.98% copper from 62 metres.
This section included 270 metres at 1.37% copper, and also 4 metres at 19.5% copper.
During this phase of drilling Blackthorn plans a series of infill holes to tighten the drill spacing over the deposit and to test the down-dip extension of the mineral resource which was considered open at depth.
Step-out drilling is also planned to test areas of the mineral resource model where mineralisation is considered open in a number of directions.
Kitumba currently hosts an Inferred JORC Resource of 87 million tonnes at 0.94% copper, using a 0.5% cut-off.
The exploration program has been designed by the MSA Group and overseen by the experienced Dr Tom Whiting who is a consultant to the company, and was formerly vice president of exploration (Minerals Division) with BHP Billiton (ASX: BHP).
