VANCOUVER,
March 3 /PRNewswire/ - African Metals
Corporation ("AFR") (TSXV: AFR) is pleased to report that the
Company has received final assay results from 4 drill holes
completed on its Luisha South Project in the Katanga Provence of
Democratic Republic of Congo. The
results confirm the continuity and grade of mineralization
identified by the June 2010 Reverse
Circulation (RC) drilling program, and with LUDH025 extends the
mineralization beyond current resource block model limits.
HIGHLIGHTS
- 48.50 meters at 1.64% Cu, 0.26% Co from 33.3m (LUDH025)
- 42.95 meters at 1.93% Cu, 0.60% Co from 2.3m (LUDH026)
Including 6.15 meters at 3.23% Cu, 0.98% Co from
2.6m.
- 22.35 meters at 2.28% Cu, 0.51% Co from 0m (LUDH032)
Including 4.45 meters at 5.62% Cu, 1.00% Co from
7.2m.
Luisha South Project Diamond Drilling
Rubaco Sprl and DrillTek Sprl, drilling
contractors, combined to complete a total of 1538.73 metres of
diamond core drilling from 22 holes at the Luisha South Project in
January 2011. The holes targeted down
dip and southeast extensions of mineralization highlighted by the
March 2010 geochemical sampling
program and June 2010 RC drilling
program.
The RC drill program enabled a JORC and
NI43-101F compliant resource estimation of the Luisha pit
mineralization, resulting in an Inferred Resource of 75,400 tonnes
of copper and 23,200 tonnes of cobalt metal. Some of the holes from
the RC program however either terminated within, or short of,
copper and cobalt mineralized horizons, producing interpolation
gaps in the resource block model. The diamond holes in the recently
completed program were designed to infill the gaps and further
define the extents of the mineralization.

The reported analytical results were from four holes cored in
the base of the Luisha open pit. Drill hole LUDH025 successfully
tested the down dip extent of the northeast pit wall
mineralization, intersecting consistent copper and cobalt
mineralization from areas that are outside of the current resource
block model; of significance are approximately ten intersections
returning >2% copper (Figure 2).
Drill holes LUDH026, LUDH027 and LUDH032
successfully tested the near surface continuity of the northeast
pit wall mineralization in locations where the June 2010 RC drilling was hindered by topographic
constraints and holes were unable to be drilled. The analytical
results support a potential upgrade to the resource model in this
part of the pit.
Mineralization styles observed in the core
included both syngenetic (bedding parallel and disseminated fine
pyrite lenses and blebs replaced by chalcopyrite and carrolite) and
epigenetic (fracture and vein hosted sulphides). Supergene minerals
malachite and heterogenite are observed overprinting and replacing
the earlier sulphide phases.

successfully tested interpolation gap in the resource block model
and confirmed down dip continuation of mineralization.

intercepts, Luisha South Project.
Notes: Grid coordinates are WGS84, Zone 35
South; Azimuth is magnetic; intersections are down hole widths, not
true widths; reported assays are length weighted average
intercepts; intercepts are based on 0.5% copper cut off, with no
top cut; reported intercepts include a maximum of two "internal
waste" sample intervals of
