Results of Leaching Test Work on the Dutwa Nickel Project, Tanzania

African Eagle Resources plc (AIM: AFE; AltX: AEA) is pleased to announce
positive results from extensive hydrometallurgical test work performed on
representative ore samples from its flagship Dutwa Nickel project in Tanzania.
The test work, using tank acid leaching at atmospheric pressure conditions,
confirmed the recovery of nickel from each of the principal Dutwa ore types and
demonstrates that an integrated two-stage leach process achieves improved metal
extraction with reduced reagent demand.

On the basis of these favourable results, the Company and its design engineer
Lycopodium are developing the preliminary Dutwa process flow sheet. The
preliminary flow sheet will be modelled in the pilot plant test programme,
scheduled to commence in the second quarter, which will result in the
confirmation of the optimal final process flow sheet and plant design for the
project, which will be reflected in the BFS.  The pilot plant programme will be
performed at the SGS Lakefield Oretest laboratory in Perth, Australia and will
process approximately 50 tonnes of ore.

Key results:
* Efficient and consistent nickel extraction by atmospheric pressure tank acid
leach confirmed
* Low acid consumption of Wamangola ore (350 to 450 kg/t) reaffirmed
* Rapid leach kinetics confirmed
* Chemistry of principal ore types validated
* Early test work on two-stage leaching achieves improved nickel extraction
over single ore type processing with reduced reagent consumption
* Preliminary process flow sheet being developed with study engineer,
Lycopodium
* Pilot-scale tests scheduled to begin Q2
* Drilling to obtain representative bulk ore samples underway


African Eagle's CEO Trevor Moss said "These test work results continue to be
very encouraging and reconfirm that Dutwa's unusual nickel laterite mineralogy
is amenable to proven atmospheric leach technology, which is in operation at
First Quantum's Ravensthorpe mine in Western Australia.  The final step of our
systematic metallurgical programme, to commence shortly, will demonstrate the
Dutwa flow sheet through the pilot plant in order to confirm the final process
selection and plant design for the BFS."

Since the completion of the scoping study update in February 2011 the Company
has been undertaking systematic and detailed metallurgical bench-scale test work
at laboratories in Perth, Western Australia, to evaluate the suitability of
various atmospheric leach processes for treating Dutwa ores.  The principal
outcome of this work was the selection of atmospheric tank leaching as the
preferred treatment process, as announced earlier this year.

This test work programme has been conducted on bulk ore samples extracted from
the Dutwa deposits by a targeted diamond drilling campaign and were designed to
confirm the initial favourable metallurgical characteristics observed in the
scoping study analyses, and to assess the variability of the ore types which are
found at Wamangola and Ngasamo.

The hydrometallurgical tank leach test work was undertaken by ALS Ammtec at its
laboratory in Perth, Western Australia.  Standardised atmospheric batch leach
tests were performed on ground whole ore composites for each of the principal
ores to investigate how the recovery of nickel varies with leaching time and
sulphuric acid addition.  The first phase of test work comprised a total of 28
tests.

Each composite, weighing approximately 0.5 tonnes, was created from sections of
diamond drill core carefully selected to ensure they were representative of each
ore type. The diamond drill hole locations were themselves chosen to be
spatially representative of the planned pit shells for each of the two deposits,
Wamangola and Ngasamo.  The predominant ore types at Dutwa have been labelled
Ferruginous Siliceous ("FeSi") and Transitional.

The chemical analyses of elements of interest in the five composites by X-ray
fluorescence (XRF) are:

+-----------------------+----+----+---+----+---+----+----+----+
|Sample |%Ni |%Co |%Fe|%Al |%Mg|%Mn |%Cr |%Si |

The compositions of the bulk samples are in good agreement with the average
compositions of mine grade material estimated from the deposit modelling by
Snowden, reported on 11 January 2011, other than Wamangola Transition 1, which
is a low magnesium variant with higher nickel content than the resource average
for Wamangola transition ore.  For this reason, a second Wamangola transition
composite was created.  Tests on this second composite have commenced.

All the bench-scale tank leach tests employed conservative conditions, such as a
relatively coarse grind size (100% passing 212 micron), and an initial solids
content of 30% w/w in the leach feed. The ores were prepared in potable water
for consistency with the expected water quality at Dutwa. The leach temperature
was 95(o)C and the leach duration was either 8 or 12 hours.  Concentrated
sulphuric acid (98%) was added at the start of the leach as the lixiviant.

Typical final results from the individual ore samples, after 12 hours leaching
at 95(o)C were:

Acid consumptions for the major "FeSi" ore type at Dutwa ranged from 350 to 415
kg/t ore, and across all samples from 350 to 625 kg/t ore.  These results
compare favourably with reported values for many Western Australian and South
American laterites, which range from 500 to 700 kg/t.  Acid consumption is
mostly at the lower end of expected ranges for atmospheric leaching of nickel
laterite ores.  As seen in previous tests, the leaching progressed rapidly.
Example results for recovery versus time are:

The results demonstrate that both "FeSi" and Transitional ores are amenable to
atmospheric tank leaching using sulphuric acid,with nickel recoveries generally
exceeding 70% after 4 hours and around 80% or higher after only 8 hours.  With
the use of leaching times longer than 12 hours, it is considered that the
ultimate nickel recoveries may be higher than those reported.  Further test work
with leach times of up to 24 hours is being undertaken by African Eagle to
confirm this. The Wamangola ores exhibit about 15% lower acid consumption than
those from Ngasamo due to their lower magnesium content, and nickel leaches from
Wamangola "FeSi" ore somewhat faster than from equivalent Ngasamo ore.
Transitional ore has faster initial leaching rates than "FeSi", which is
attributed to a greater proportion of the nickel being hosted in clay and
serpentine minerals rather than goethite.

African Eagle also tested an integrated leaching process, with "FeSi" ore in an
initial leach stage and transitional ore added in a second stage, to assess the
viability of processing both Dutwa ore types in a single leach circuit. The
tests were performed at 95(o)C, typically for 16 hours.  The test parameters
examined included the ratio of "FeSi" to Transitional ore, consistent with the
Dutwa deposit and mining models, and total acid addition.  Transitional ore is a
significant component of the Ngasamo deposit.

* 12 hour test

The results of these tests suggest that a two-stage leaching process could be
used to treat "FeSi" and Transitional ores, in the same proportions by mass as
they occur in the Dutwa deposits.  Good overall nickel recoveries (ranging from
81% to 87%) were achieved from Wamangola ore, with sulphuric acid additions of
350 to 450 kg/t ore, equating to acid consumptions of only 38 to 41 tonne of
acid per tonne of nickel recovered. Due to their chemistry and mineralogy, the
Ngasamo ores required 50 to 100 kg acid/t ore more than Wamangola ores to obtain
nickel recoveries above 80%.

Lower acid and iron concentrations were observed in the final leach solutions
from these tests.  Two-stage leaching is anticipated to offer benefits such as
lower overall acid consumption and reduced reagent demands compared to leaching
of individual ore types alone.  Additional testing is being undertaken to
develop and optimise the Dutwa leach process further.

About Dutwa

Dutwa was discovered in 2008 and has a JORC resource of 99 million tonnes at
0.93% Ni.  The project is a nickel laterite project with unusually beneficial
geometallurgical properties, which makes it amenable to straightforward
atmospheric acid leaching with comparatively low acid consumption.  This
combined with ready mining from two hilltop deposits leads to strong project
economics.  A Bankable Feasibility Study is currently underway and due around
the end of 2012.
