Feasibility work UPDATE at New liberty

Aureus Mining Inc. ("Aureus" or the "Company"), the TSX (AUE) and AIM
(AUE) listed exploration and Development Company focused on gold in
sub-Saharan Africa, provides an update on the feasibility work
undertaken at the Company's 100 % owned Bea Mountain Mining licence in

* Approximately 4,450 metres of infill drilling complete - a
further 15,000m planned

* Detailed geotechnical and metallurgical work in progress

* Definitive feasibility study on track for Q4 2011.

David Reading, President and CEO of Aureus commented:"Aureus Mining is
focused on moving New Liberty towards a definitive
feasibility study and ultimately through to production with a minimumtarget
of 100,000 ounces of gold per year. Our commitment to the
feasibility and exploration objectives is endorsed by our new contract
for diamond drilling programmes."

Feasibility work commences - Company on track to complete DFS by Q4

Based on a positive Preliminary Economic Assessment completed by the
Company in December 2010, the DFS supports an open pit mine and gold
processing plant with an average annual production rate of 850,000
tonnes of ore over an 8.5 year production life. In the first 5 years of
the project, forecast gold production is expected to average 100,000
ounces per year with total gold production for the project expected to
be some 786,700 ounces.

In-fill Drilling Activities

4,450 m of infill diamond core drilling has been completed to the end
of Q1, 2011. An additional 15,000m is planned. Additional diamond drill
rigs are en-route to the project and all drilling for the DFS is
planned to be complete by the end of Q3 2011. The infill diamond
drilling operations are being conducted in order to:

* Provide additional geological resource knowledge with particular
emphasise being placed on infill drilling of areas identified to add
additional resource tonnages within the current defined pit shell

* Obtain metallurgical samples for testing to update the mill
comminution and recovery test work previously completed by SGS
Lakefield of Canada, and Mintek of South Africa. The work will be aimed
at providing final design parameters for the grinding circuit together
with investigations to improve recovery performance and optimise
reagent additions.

* Complete within the diamond drill programme approximately 8,000m
of drilling specifically located for geotechnical and pit definition
assessments in order to optimise the planned open pit wall designs in
order to minimise all waste mining operations.

Other key DFS Areas

The project environmental and social impact assessment was started by
Golders Associates Africa Ltd (GAA) in August 2010 and the study is on
track to be completed within the DFS period in 2011. GAA is also
engaged in the design aspects of the tailings dam facility of the
project feasibility study.

The geotechnical and hydrology test work, and the mine planning and
optimisation work for the open pit designs are being conducted by
Australian Mining Consultants (UK) Ltd and are planned for completion
by the end of Q3 2011. AMC will also, in collaboration with the Aureus
Geological team, be responsible for updating a 43-101 compliant
resource statement for the DFS on completion of the in fill drilling

The metallurgical test work programmes, process and gold plant design
studies will be managed by an appropriate mineral processing
contractor. A tender process is being undertaken by the Company at
present to select a suitable contractor.

include the New Liberty gold deposit in western Liberia (the "New
Liberty Gold Project"), which has an estimated Indicated Mineral
Resource of 751,000 ounces of gold grading 4.17 g/t (contained in
5,599,000 tonnes) and an estimated Inferred Mineral Resource of 762,000
ounces of gold grading 3.40 g/t (contained in 7,040,000 tonnes). The
New Liberty Gold Project is being advanced through a bankable
feasibility study, and the proximal Ndablama, Weaju, Silver Hills and
Gondoja gold projects are all within the Company's Bea Mountain 25 year
renewable Mineral Development Agreement.

In addition, the Aureus Mining has an approximate 14% interest in
AIM-listed diamond producer Stellar Diamonds Plc (AIM: STEL, ) which is advancing the highly diamondiferous
Druzhba kimberlite pipe.

Forward-Looking Information

This press release contains certain forward-looking information. All
information, other than information regarding historical fact, that
addresses activities, events or developments that Aureus Mining
believe, expect or anticipate will or may occur in the future is
forward-looking information. Forward-looking information contained in
this press release includes, but may not be limited to, the future
plans and objectives of Aureus Mining and their anticipated future
growth, the admission and listing of the common shares of Aureus Mining
as set forth above, mineral resource estimates and the anticipated
exploration and development activities of Aureus Mining. The foregoing
and any other forward-looking information contained in this press
release reflects the current expectations, assumptions or beliefs of
Aureus Mining based on information currently available to Aureus
Mining. With respect to the forward-looking information contained in
this press release, Aureus Mining has made assumptions regarding, among
other things: general business, economic and mining industry
conditions; and it has also been assumed that no material adverse
change in the price of precious and/or base metals occurs, no unusual
geological or technical problems occur and no significant events occur
outside of the normal course of Aureus Mining's respective business.

Such forward-looking information is subject to a number of risks and
uncertainties that may cause actual results or events to differ
materially from current expectations, including: risks normally
incidental to exploration and development of mineral properties;
uncertainties in the interpretation of results from drilling and test
work; the possibility that future exploration, development or mining
results will not be consistent with expectations; uncertainty of
mineral resources estimates; adverse changes in precious and/or base
metal prices; and future unforeseen liabilities and other factors
including, but not limited to, those listed under "Risk Factors" in the
Information Circular of African Aura dated February 28, 2011, a copy of
which is available on SEDAR at , and in the Aureus Mining
Admission Document, a copy of which is available at .

Any mineral resource figures referred to in this press release are
estimates and no assurances can be given that the indicated levels of
minerals will be produced. Such estimates are expressions of judgment
based on knowledge, mining experience, analysis of drilling results and
industry practices. Valid estimates made at a given time may

change when new information becomes available. While Aureus Mining
believes that the mineral resource estimates in respect of their
respective properties are well established, by their nature mineral
resource estimates are imprecise and depend, to a certain extent, upon
statistical inferences which may ultimately prove unreliable. If such
mineral resource estimates are inaccurate or are reduced in the future,
this could have a material adverse impact on Aureus Mining, as
applicable. Due to the uncertainty that may be attached to inferred
mineral resources, it cannot be assumed that all or any part of an
inferred mineral resource will be upgraded to an indicated or measured
mineral resource as a result of continued exploration.

Forward-looking information speaks only as of the date on which it is
made and, except as may be required by applicable law, Aureus Mining
disclaim any obligation to update or modify such forward-looking
information, either as a result of new information, future events or
for any other reason.
