Nigel Ferguson, the President of African Metals Corporation (TSX Venture Exchange: AFR) is pleased to report that the Company has received final assay results from the remaining 14 holes of the 21 holes completed during the June 2010 Reverse Circulation percussion drilling program, conducted on its Luisha South Project in the Katanga Provence of Democratic Republic of Congo.
Reverse Circulation Drill Assay Results Titan Drilling Sprl completed a 2,002 meter drilling program at the Luisha South Project in June 2010. Nineteen angled and two vertical holes were drilled in the vicinity of the historical Luisha South Pit. Fifteen holes were collared to the northwest, west and south of the pit, whilst six holes were collared in the pit floor. Drilling tested the potential for mineralization both down dip and along strike from the current excavated open pit and also tested significant high grade copper and cobalt assay results returned from trench and adit sampling completed earlier in March of this year and reported on the 15th June 2010. Drill samples were collected from all holes at one meter intervals, and riffle split to produce approximately one kilogram sub-samples for analysis. A total of 1,462 samples including QC controls were dispatched to SGS Minerals laboratory in Kalulushi, Zambia for sample processing and analysis. Assay results from the first 7 holes (LURC014A to LURC020) indicated that the ‘upper’ and ‘lower’ mineralized horizons from mines such as Kipoi Central (Tiger Resources) were present in the Luisha South mineralization (refer AFR press release 23 August 2010). Assay results from the remaining fourteen of the twenty-one drill holes have now been received including drill holes LURC001 to LURC014. Holes LURC001, LURC002, LURC003 and LURC005 were collared on the southwest side of the Luisha Pit to test the hanging wall of the historic Pit mineralization. All holes intersected broad intervals of copper and cobalt mineralization. All holes failed to penetrate through to the barren basal sedimentary breccia unit due to ground conditions, indicating that the mineralization is still open at depth and further testing with diamond core tails is required. Holes LURC013 and LURC014 were collared on the surface on the northwest edge of the pit testing for a transverse fault offset to mineralisation. Both intersected basal sedimentary breccia units, confirming the presence of an offset structure. Ground water issues forced the early abandonment of two of the fourteen drill holes reported, namely LURC006 and LURC012. Drill hole LURC012 terminated in significant copper and cobalt mineralization on the southwest side of the Luisa Pit, whilst LURC006 was terminated above the mineralized stratigraphy down dip of LURC002. Both will be further tested with diamond core tails. Geological logging and interpretation of the drill chips suggest that the mineralization is hosted by dolomitic siltstone and carbonaceous siltstone of the upper Roan Formation (SD2D to SD3B) and basal dolomitic arenites and stromatolitic units of the Lower Kambove (formerly CMN). The interpretation is significant as these units host the ‘third’ ore horizon in other nearby mines along the line of lode such as the Kipoi Central copper deposit as defined by Tiger Resources Ltd. Geological interpretations suggest that all 3 mineralized horizons are present in the Luisha Project. Anomalous length weighted drill intercepts based on 0.5% Cu cut off are summarised here  |
