The resources stated above are approximately double those which the
company had targeted through its second round of drilling at the Luisha
South Project and includes significant tonnages of lower grade material
from the hanging wall mineralised zone as well as depth continuation of
higher grade mineralisation from the footwall zone. The majority of the
resource estimate incorporates veined and disseminated chalcopyrite and
carrolite sulphide mineralization, with oxide malachite and
heterogenite mineralization predominantly in the footwall zone, beneath
the base of the pit, and near surface on the hanging wall.

Nigel Ferguson, CEO and President of African Metals Corp, commented:

“The Company is very pleased with this resource update, which is
expected to continue to grow in the coming months. A drill rig will be
mobilising to site prior to the wet season starting in November to
infill and extend zones of mineralisation untested by the previous
Reverse Circulation (RC) and Diamond drilling programs. Management
expects further increases in the total contained metal content
estimated for the Luisha South Project and conversion of resource
material from Inferred to Indicated and possibly Measured resource
category. Concurrently the Company will continue surface drilling to
seek extensional mineralisation outside the current resource area.
Mineralization remains open at depth, to the south and to the

“AFR has achieved great success in the field and with a larger resource
estimate the company is hopeful that this will support commercial
operations to upgrade the copper and cobalt mineralisation through a
DMS concentration plant and subsequent floatation circuits. The Company
is targeting concentrate production by the end of Q3, 2011.”


Luisha South Diamond Drilling
Rubaco Sprl and DrillTek Sprl, drilling contractors, combined to
complete a total of 1,538.73 metres of diamond core drilling from 22
holes at the Luisha South Project in January 2011. The holes targeted
the down dip and southeast extensions of mineralization highlighted by
the March 2010 geochemical sampling program and the 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 5.8 million tonnes at 1.3% copper, and 0.4% cobalt for
75,400 tonnes of contained copper metal and 23,200 tonnes of contained
cobalt metal (using 0.5% copper cut-off).

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 technical report documenting the resource
estimation is currently being reviewed by AFR personnel and will be
submitted to the Toronto Venture Exchange in order to meet their
pre-filing guidelines for resource disclosures. An 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.

Bulk Density Measurements
Bulk density work was completed in two stages, bulk density
determinations from RC drill chips and determinations on core from
diamond drilling.  In total, 912 bulk density determinations were made,
266 from RC chips and 646 from diamond drill core. RC chip bulk
densities were measured by SGS Minerals Laboratory in Kalulushi, Zambia
and diamond core work was completed by AFR staff. A bulk density of 2.5
was used to complete the resource estimate based on these measurements
and is considered appropriate for these type of rocks.

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 June 2011.

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 (zone 35 south) co-ordinate

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
25mN by 12.5mE and 2.5mRL. These cells were further sub-blocked to
12.5mN by 6.25mE and 1.25mRL. All relevant attributes were coded into
the block model.

Grade estimation was performed using ordinary kriging 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

Drill Hole Sampling and Assaying Procedure
The Company undertakes drilling and sampling to strict guidelines. The
core was collected from the drill rig at the end of each shift,
processed for RQD geotechnical logging, and digitally photographed. The
drill core was predominantly NQ in size, with a small percentage of HQ
core in the upper 20m of holes cored from surface in clay soils. Core
was ‘fitted’ back together whenever possible, and geologically logged
on site by the supervising project geologist. The project geologist
ensured a representative cutting line was marked along the length of
the core and samples highlighted at appropriate intervals. Once the
sample intervals and cut lines had been clearly marked out, the start
and end of each sample interval was cut orthogonal to the long axis of
the core to clearly define the end of each sample interval. The core
was then cut in half lengthways along the representative cut line. A
stand mounted, diamond impregnated electric saw blade purchased from
Johannesburg, South Africa, was used for all core cutting purposes. The
left half of the core was returned to the metal core trays and retained
for future reference; the right half was placed into appropriately
marked and labeled plastic sample bags. Quality Control protocols
enforced by the company require the collection and insertion of
Certified Reference Materials (CRM’s) at the rate of one CRM “blank”,
one field blank (sand), one CRM “copper standard” and one field
duplicate sample within each sample stream of 20 samples.

Samples were delivered under security by company vehicle to SGS Minerals
Laboratory in Kalulushi, Zambia for sample preparation and analysis.
The laboratory maintains quality assurance protocols in line with ISO
17025, and maintains quality accreditation for commercial laboratories
in line with ISO 9002. The laboratory also participates in
international round robin programs organized by LQSI of the USA.

The sample preparation scheme was PRP90; drying for 4 hours at 105
degrees Celsius; crushing to 2mm with 90% passing 2mm; and pulverizing
of a 1000 gram sub-split of the 2mm chips to 85% passing 75 microns.
Digest was scheme DIG42S; 0.4 grams of pulverized material digested in
a 4 acid mixture on a hot plate at 200 degrees Celsius for 45 minutes,
with subsequent dilution back to 100ml before AAS analysis by method
‘AAS42S’. Results for copper and cobalt were reported in percentages.
Lower detection limits were 0.01% for both elements.

About African Metals Corporation.
African Metals Corporation [TSXV "AFR"] is a Canadian listed company
focused on the discovery and development of Copper and Cobalt deposits
in the highly mineralized Katanga Copper Belt of the world renowned
Africa Copper Belt in the Democratic Republic of Congo (“DRC”).

AFR purchased all the assets of Chevalier Resources Inc. in March 2010
including a 57% interest in the Luisha South Project contained within
licence PEPM 4881, Katanga Provence, Democratic Republic of the Congo
(“DRC”) through subsidiaries incorporated in the DRC. In July AFR
negotiated a further 18% interest in the project with the option to
increase the equity interest to 90% based on results. The project is
located 75 kilometres northwest of Lubumbashi, the capital of Katanga
Province and consists of approximately 16.2km².

The Luisha South Project includes a small historical open pit mine and
associated stockpile and is underlain by Roan Group sediments which
host major Cu-Co deposits in the DRC. The Luishia South ore body was
explored between 1923 and 1928 and an oxide deposit with an estimated
pre-production tonnage of approximately 350,000 tonnes at 8.6% Cu was
delineated (the resource estimate non-compliant in terms of NI
43-101).  The Luisha Project also covers some three kilometres of the
Roan Group strike length which is favorable for Cu-Co mineralization. 
AFR is currently conducting metallurgical tests on stockpile Reverse
Circulation drill samples to determine characteristics and heavy media
separation qualities, with the aim of commencing production of an oxide
concentrate by the end of Q3 2011.
