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.

from surface and 12 as diamond tails to RC pre-collars; holes with
reported assay results are highlighted red (4).

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.

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