African Metals Corporation ("AFR") (TSX VENTURE: AFR)(FRANKFURT:
OWW) is pleased to provide initial figures for resources estimated
by Geosure Exploration & Mining Solutions Pty Ltd, independent
geological consultants, for its Luisha South Project in the
Democratic Republic of the Congo.
The resource as estimated includes:
An Inferred 5.8 Million tonnes at 1.3% Cu for 75,400 tonnes of
contained copper metal and 0.4% Co for 23,200 tonnes of contained
cobalt metal.
Resource modeling was also completed at various cut off grades
as presented in Table One below and includes a higher grade
inferred resources of some 1.8 million tonnes at 2% Cu and 0.4% Co
for 36,000 tonnes of contained copper metal and 7,200 tonnes of
contained cobalt metal.
The resources stated above are more than double those which the
company had targeted through its initial drilling program at the
Luisha South Project.
Nigel Ferguson, CEO and President of African Metals Corp,
commented:
"The Company is very pleased with this maiden resource estimate,
which is expected to continue to grow in the coming months. A
diamond drill rig will be mobilising to site soon to infill and
extend zones of mineralisation untested by the previous RC drilling
program., Management expects further significant increases in the
total contained metal content estimated for the Luisha South
Project.
Concurrently the Company will continue surface drilling to seek
extensional mineralisation outside the current resource area."
MINERAL RESOURCE MODEL
Discussion
Titan Drilling Sprl completed a 2,002 meter RC 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. 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 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 a one kilogram
sub-samples for analysis. A total of 1,462 samples including QC
samples were dispatched to SGS Minerals laboratory in Kalulushi,
Zambia for sample processing and analysis.
An independent resource consultant, Geosure Exploration &
Mining Solutions Pty Ltd, visited the project between the 15th and
17th August as part of the due diligence requirements for resource
estimation for the Luisha South Project. All data was made
available to the consultant in order for the resource to be
estimated.
Further Drilling at the Luisha South Project
A diamond drilling program has been planned to be underway on
the 15th October 2010. The program is a combination of new holes
from surface and tails to existing RC drill holes. Geological
interpretation of the June RC drill program indicated that a number
of the holes either finished short of, or within, zones of
mineralization; ground water being the common cause of early hole
termination. Positive data from the diamond holes would enable an
upgrade to the maiden resource assessment, which will be released
to the market once all data has been reviewed and assessed.
Mineral Resource Classification
The Luisha South Mineral Resource Estimate has been prepared by
Mr. Michael Montgomery, Director of Geosure Exploration &
Mining Solutions Pty Ltd. Mr. Montgomery has sufficient experience
which is relevant to the style of mineralization under
consideration and to the activity which he is undertaking to
qualify as a Competent Person as defined the by NI 43-101
standards. The resource is currently being reviewed by AFR
personnel and will be submitted to the TSX Venture Exchange in
order to meet their pre-filing guidelines for resource disclosures.
A NI 43-101 compliant technical report documenting the resource
estimate will be filed on SEDAR within 45 days of the date of this
news release.
The Inferred Resource is detailed in the Table One below.

Bulk Density Measurements
SGS Minerals Laboratory in Kalulushi, Zambia as well as
undertaking all analytical work for the RC drill samples also
provided all bulk density data based on work completed on a suite
of 266 samples taken from RC drill chips. A bulk density of 2.09
was used to complete the resource estimate.
Mineralisation Modelling
Geosure Pty Ltd of Brisbane, Australia was contracted to
undertake the resource estimations. A wireframe model of the
mineralised system was based on all available information as at
August 2010.
The Luisha South deposit was modelled using Surpac 6.1.4
software. A digital terrain model was supplied to Geosure for
topography. Closed 'wireframe' solids were created to define
geological domains. All modelling was completed in supplied WGS 84
co-ordinate system.
Variography was used to describe the spatial variability of both
copper and cobalt. This variability was measured in the form of a
mathematical model known as a variogram. These models were then
used with a kriging algorithm to recreate the spatial continuity
determined through variogram modelling. Drill data was composited
to two (2) metre intervals within geological domains to standardise
sample support.
A 3 dimensional block model was constructed using Surpac Mining
Software. The block model was constructed with a parent cell size
of 20mN by 10mE and 5mRL. These cells were further sub-blocked to
5mN by 2.5mE and 1.25mRL. All relevant attributes were coded into
the block model.
Grade estimation was performed using OK methodologies in Surpac
Mining Software. Grade estimates were constrained to within the
mineralized geological domains. Grade estimation parameters were
derived from several trials and included comparing block estimates
to mean composite drill grade.
