Paul Thomson, whose appointment is effective from September 1, 2011 is a Chartered Accountant and has extensive accounting and corporate finance experience gained over 14 years with Ernst & Young and, more recently, as a Senior Manager within the Business Development Group at Kazakhmys Plc, where he was heavily involved in project financing and development along with significant mergers and acquisitions activity.

Financial summary for Q2 2011

The Company ends the second quarter of 2011 with US$ 46.9 million of cash, leaving it with a strong balance sheet. The loss for the quarter predominantly relates to share based payment charges and legal fees relating to the public offering. These are non-recurring charges. The current cash position of the Company is US$ 44.3 million.

The following table presents a summary of selected financial data:

New Liberty Feasibility Programme

Feasibility Study due by the end of 2011 - The Company expects to have completed its New Liberty Feasibility Programme and to have published the results by the end of 2011. These results will include detailed economics of the New Liberty Mine.

Infill Drilling Programme nears completion - The Company is continuing with the infill diamond drilling programme at the New Liberty deposit and to date over 21,000 metres (157 holes) of a 25,000 metre (180 hole) programme have been completed. With an optimal hole spacing of between 30 to 40 metres, the programme is designed to evaluate the total contained gold resources that could potentially fall within an open pit, covering a strike length of 1.75km and down to a depth in excess of 200 metres below surface. These are the approximate dimensions of the open pit design as defined within the Preliminary Economic Assessment ('PEA'), based on the previous resource estimate, and filed by the Company in December 2010.

The present drill programme is designed to fill in the gaps within known mineralised ore body and outline potential extensions to the previous resource estimate, with the objective of trying to expand the resources that will fit within an optimized open pit.

Results from the first 25 holes (6,191m) of the New Liberty feasibility drill programme returned good intercepts and include reported highlights as of July 12, 2011 of:

·; 5.3 g/t over 13 metres

·; 6.3 g/t over 10 metres

·; 3.6 g/t over 33 metres

·; 10.9 g/t over 4 metres

·; 5.3 g/t over 11 metres

·; 3.9 g/t over 20 metres

The results to date confirm the tenor of the gold mineralisation outlined in the previous resource estimate, and are confirming and extending the continuity of the mineralisation system of this shear-hosted ore body.

A full summary of the all the borehole results to date is given in the Company's press release of 12 July 2011 and is available for review at the Company's website, www.aureus-mining.com.

Metallurgical Design - DRA have been appointed to undertake detailed metallurgical test work to definitive feasibility level, and then complete all design work and cost estimation studies for the capital build and operation of the process plant. This work has commenced with the shipment of over 500 kg of drill core to South Africa to undertake detailed test work on CIL, flotation recovery and optimisation of the grind size required from the milling process. DRA will investigate the viability of incorporating a flotation recovery process within the process design as part of the feasibility study. If successful, this would be a significant factor in the process design resulting in a smaller plant and a reduction in grinding requirements, lowering of capital and operating costs.

ESIA - The Company has retained the services of Golders for the environmental and social impact assessment of the New Liberty Project. Progress to date includes the completion of the ecology, surface water, air-quality and socio-economic base line studies within the area covering the New Liberty proposed mining infrastructure. Detailed baseline environmental studies for soils and ground hydrology are on-going and are planned to be completed in Q4 2011. It is planned to start the ESIA public consultation process in Q3.

Mining Design - The Company has retained AMC to undertake the NI 43-101 resource classification on completion of the infill drilling programme, and to undertake the open pit design and mining optimisation studies for the feasibility design work. As part of the in-fill drilling programme, a 23 borehole geotechnical and hydrology programme, designed by AMC, has been completed. The slope designs of the open pit are being assessed and optimised through this programme of geotechnical logging and rock strength assessments, together with the ground hydrology testing.

Tailings Facility - The Company has also retained the services of Golders for the design studies and capital build cost estimate of the tailings facility. Ground geotechnical and hydrology studies are currently being conducted as part of the design studies.

Sterilisation Drilling - A programme of sterilisation drilling is scheduled to be completed during Q3 2011 for the major infrastructure sites of the metallurgical process plant, tailings dam facility and the mine waste rock dump.

Power Supply - The Company is also carrying out an investigation into alternative power supply options for the project, in order to enhance the project economics. Current studies are focused on the potential use of a bio-mass power generation system, using wood chips supplied from rubber plantation regeneration projects within Liberia, as an alternative to diesel-fuel power generation. Both options will be investigated as part of the definitive feasibility study. It is planned to complete a capital and operating cost comparison review during Q3.

The definitive feasibility study will be co-ordinated and compiled by the Company under the supervision of the Chief Operating Officer, Dr Martin White, and is expected to be completed by the end of 2011.

Exploration Activities

New Liberty Extensions - An eight hole, diamond drill programme (K172 - K179) totalling 1,101 metres was completed to the west of the currently defined gold resources at New Liberty. Drilling covered a potential westerly strike extension of the mineralised systems for 500 metres. Encouraging drill intercepts of 9m at 1.25g/t and 10m at 5.25g/t were intersected some 150 metres west of the edge of the planned New Liberty open pit outlined in the Company's Preliminary Economic Assessment reported by African Aura Mining Inc. in the press releases of 14 December 2010 and 21 December 2010.

The geology and mineralisation intercepted in these drill holes is identical to that encountered in the New Liberty deposit. The new area of mineralisation would appear to have a potential strike extent of 100 metres. Holes drilled west and east of this area did not return any significant intercepts.

Ground geophysical work and soil sampling is in progress over the western and eastern extensions to the New Liberty ore body. The geophysical survey, involving magnetic and induced polarisation methods, has been completed over the western portion of the New Liberty deposit and its western extensions. This work highlights that the New Liberty mineralisation has a strong geophysical signature, as defined by high chargeability and low resistivity readings from the induced polarisation method. Furthermore, the ultramafic host rock has a strong magnetic signature as defined by the ground and airborne magnetics. Work to date suggests a potential western extension of 500 metres and further drilling is required to test this potential target area. A number of additional chargeability targets have been outlined within the western portion of the ore zone and could represent new, potentially mineralised, shear structures. These targets will also require drill testing.

To date, 56.8 kilometres of line cutting has been undertaken along the potential western and eastern extensions to New Liberty and 956 soil samples have been collected with results pending. Ground magnetic surveys and gradient array IP work is presently in progress along the potential eastern extension to the New Liberty deposit.

Ndablama Prospect, multiple mineralised zones outlined -The Ndablama prospect ("Ndablama") is located approximately 40 kilometres north east of the New Liberty project and within the Company's 100% owned Bea Mountain Mining Licence of 457km². Over one kilometre of intensive artisanal activity has been worked over at Ndablama and includes associated gold in soil anomalies with values of between 150 and 3,000 ppb. Previously, the Company reported trench and diamond drill hole results which defined an area of 150 metres east - west by 900 metres north - south. This zone is referred to as the Central zone. Further trenching to the north and south east of the Central zone has highlighted additional mineralised zones, which are referred to as the North and East zones.The North and East zones both have approximate dimensions of 200 metres in a north - south direction. In all cases gold bearing rocks are associated with sheared, folded and altered amphibolites and talc-tremolite schists close to their contacts with granite dykes and pegmatites.

To date a total of 63 trenches and 15 drill holes have been completed at the Ndablama prospect. A full summary of the all the borehole and trench results at Ndablama are given in the company's press releases of 19 April and 12 July 2011 as well as the July 2011 Corporate Presentation. All of these documents are available for review at the Company's website, www.aureus-mining.com.

Further trenching and channel sampling has been undertaken and focused predominantly over the Central and Eastern zones and potential structural splays which may link these two zones. Once all the results from this comprehensive sampling programme have been received the Company will finalise the phase two diamond drilling programme of the Ndablama prospect.

Interpretation of all available information indicates both vertical and shallow dipping orientations to the zones of gold mineralisation. A ground magnetics survey is planned for September 2011 and a phase two diamond drilling programme is planned for Q4 2011.

Gondoja Target - Further soil sampling work is in progress to cover the area from the Ndablama prospect to the Gondoja target within a structural corridor approaching 11.5km strike length. Forty line kilometres of soil gridding has been completed, and to date, 1,501 soil samples have been collected and sent for analysis. Results are pending.
