About Aureus Mining

The Company's assets include the New Liberty gold deposit in Liberia (the "New Liberty Gold Project"), which has an estimated Reserve of 873,000 ounces of gold grading 3.1 g/t and an estimated Measured and Indicated Mineral Resource of 1,086,000 ounces of gold grading 3.6 g/t and an estimated Inferred Mineral Resource of 483,000 ounces of gold grading 3.5 g/t. A technical update for the New Liberty gold project was released on February 2, 2012, derisking and building on the robust preliminary economic assessment ("PEA"), filed in December 2010. This update outlined an improved pre-tax NPV of US$260 million based on a US$1,350/oz. gold price and a discount rate of 8%, with an eight year mine life and production of 123,000 ounces per year modelled for the first four years.

The New Liberty Gold Project is located within the Bea Mountain mining license which covers 457km² and has a 25 year, renewable, mineral development agreement. The Bea Mountain mining license also hosts the proximal gold targets of Ndablama, Weaju, Silver Hills and Gondoja, which are the focus of exploration programs during 2012.

The Company also has gold assets within exploration properties in Cameroon.
