African Metals Corporation (TSX VENTURE:AFR)(FRANKFURT:OWW) has provided an update on exploration activities at its Luisha South Project in the Democratic Republic of the Congo.
Summary
A total of 1538.73 metres of diamond core drilling from 22 holes was completed at the Luisha South Project in January 2010. The holes targeted down dip and southeast extensions of mineralization highlighted by the June 2010 RC drilling program. Ten angled and vertical holes were collared in the base of the open pit whilst twelve holes were collared to the south and southeast of the pit.
Luisha South Open Pit Diamond Drilling
Rubaco Sprl and DrillTek Sprl combined to complete a 22 hole, 1538.73 metre drilling program at the project.
The drill holes around the open pit intersected consistent Chalcopyrite and Carrolite mineralization. Chalcopyrite is a copper-iron sulphide mineral that commonly weathers to form the high grade copper mineral malachite. Carrolite is a cobalt sulphide mineral composed of approximately 40% cobalt and 20% copper in its chemical makeup, the remaining percentages going to iron, sulphur and minor nickel. Carrolite weathers to produce the high grade cobalt mineral heterogenite. Mineralization styles observed in the core include both syngenetic (bedding parallel fine pyrite lenses and blebs replaced by Chalcopyrite and Carrolite) and epigenetic (fracture and vein hosted sulphides).
Geological logging of the drill core continues, and core samples are expected to be dispatched to SGS Minerals Laboratory in Kalulushi, Zambia in late January for processing and analysis. Analytical and SG determination results are expected to be available by early to mid-March, depending on processing delays at the laboratory.
AFR plans to courier selected samples from the RC and diamond drilling programs to suitable consulting groups in South Africa for metallurgical test work. The upgraded geological interpretation, assay and metallurgical results will be used to calculate a revised estimate of the maiden resource, and initiate desktop mining studies.
