Oriental Minerals Becomes Woulfe Mining Corp., Rebirth of the Company

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 25, 2010) - Woulfe Mining Corp. (TSX VENTURE:WOF) ("Woulfe" or the "Company") (formerly Oriental Minerals Inc. (TSX VENTURE:OTL)) announces that effective today, Oriental Minerals has changed its name to Woulfe Mining Corp. and has commenced trading on the TSX Venture Exchange under the symbol "WOF".

Woulfe Mining Corp. Focus.

Woulfe Mining has secured a portfolio of mining leases in South Korea consisting of mines closed during the downturn in metal prices. The mines have known mineralization, extensive mine development and surface support infrastructure and thus can readily be reactivated.

Our flagship and prime focus is the Sangdong Mine which up to its closure in 1992 was a significant producer of tungsten and molybdenum with credits for bismuth and gold. The Sangdong Mine was owned and operated by Korea Tungsten which led the way in the development of large steel companies such as POSCO and the manufacture of tungsten and molybdenum related products. The Sangdong project is strategically located 175 km south east of Seoul, the capital of South Korea, a ready market for Woulfe's production with several companies consuming tungsten and molybdenum there.

The Company will complete a scoping of the project and economic assessment study in early March, 2010 to consider the reopening of Sangdong mining operations using modern mining techniques to support a 2.5 million tonne per annum processing facility. Mineral processing will be based on known technology with crushing, grinding, flotation and gravity separations to produce ammonium paratungstate ("APT") to be sold primarily into domestic Korean markets. Sangdong is also well placed being close to the world's manufacturing giants China and Japan.

Meetings held with the local community and county leaders in January, 2010 have been extremely positive with promised cooperation and assistance in the redevelopment of the Sangdong Mine.

Processing tungsten is by flotation and gravity methods and no environmentally harmful chemicals are therefore released. An environmental review of the Sangdong Mine was commissioned in February, 2010 and this will be released to the market shortly.

The South Korean economy has outperformed all economies world wides, boasting the world's highest growth rate escaping recession during the recent global financial crisis.
