VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 14, 2011) - Nigel Ferguson, the President of African Metals Corporation (News - Market indication)(FRANKFURT:OWW) is pleased to report that the Company has received final assay results from the 42 Reverse Circulation (RC) drill holes completed on the stockpile at its Luisha South Project in the Katanga Provence of Democratic Republic of Congo.
HIGHLIGHTS
A 42 hole, reverse circulation (RC) drilling program conducted on top of the historic Luisha South open pit stockpile produced 416 samples from 383 metres of drilling.
Analytical results of the RC samples indicate that the stockpile hosts zones of elevated grades of copper (>1%) and cobalt (>1%) mineralization. Similar assay results were produced by excavator sampling conducted by Strathcona in 2007 and reported in 2008. Significant Length Weighted Average (LWA) drill intercepts include:
- 7 metres at 0.59% copper, 1.15% cobalt from 0 metres (SPRC018)
- 8 metres at 0.54% copper, 1.04% cobalt from 0 metres (SPRC019)
- 6 metres at 0.79% copper, 1.04% cobalt from 0 metres (SPRC020)
- 9 metres at 2.63% copper, 0.52% cobalt from 0 metres (SPRC021)
- 11 metres at 3.82% copper, 0.94% cobalt from 0 metres (SPRC026)
- 8 metres at 2.47% copper, 0.38% cobalt from 0 metres (SPRC027)
- 8 metres at 2.53% copper, 0.46% cobalt from 0 metres (SPRC028)
- 9 metres at 1.82% copper, 0.16% cobalt from 0 metres (SPRC029)
- 10 metres at 2.19% copper, 0.36% cobalt from 0 metres (SPRC030)
- 8 metres at 2.21% copper, 0.33% cobalt from 0 metres (SPRC033)
- 7 metres at 0.94% copper, 1.06% cobalt from 0 metres (SPRC038)
Luisha South Project Stockpile RC Drilling
In October 2010, Magnum Drilling Sprl completed a 42 hole, Reverse Circulation (RC) drilling program on top of the Luisha South stockpile (Table 1, Figures 1).

Union Minière du Haut-Katanga (UMHK), an historic mining company, conducted open pit mining of the Luisha South deposit between 1913 and 1939. The stockpile represents the remnants of the ore that was processed during this period.
The RC program produced 416 samples including QC controls from 383 metres of drilling. The RC program was designed to highlight the potential copper and cobalt grades of the stockpile, and their respective spatial distribution.
Samples were collected at one meter intervals, and riffle split to produce approximately one kilogram samples for analysis. All samples including QC controls were dispatched to ALS Laboratories in Johannesburg, South Africa, for sample processing and analysis. All samples were analyzed by method ME-ICP61 following sample prep and a 4 acid digest. The analytical results of the QC samples (standards, blanks, and field duplicates) were within acceptable limits.
Anomalous length weighted drill intercepts based on 0.1% Cu cut off are summarised in Table 1.
Cavities were intersected in 12 of the 42 holes, resulting in NSR or No Sample Return. It is not known whether the source of the cavities is due to the rubbly, poorly sorted nature of the stockpile, or weathering.
The analytical results indicate that the northeastern half of the stockpile hosts the higher copper and cobalt grades, with smaller high grade pockets occurring in the south. Sulphides were not observed during the logging of the drill chips.
Based on the positive assay results and the observation that the mineralization is of an oxide nature (malachite and heterogenite), AFR has approached metallurgical companies including Mintek in Johannesburg, RSA, and METS in Perth, Australia, to conduct beneficiation test work aimed at producing a higher grade concentrate amenable to conventional hydrometallurgical leaching. The company plans to commence test work in February, with beneficiation results expected during mid to late March.
AFR also intends to estimate a copper and cobalt resource of the stockpile based on the results of the RC drilling. The resource is expected to be issued by the end of March.
