Marifil Aquires 47,150 Ha of Potash Lands

Geologic Studies Suggest Good Probability of Potash, Uranium, Lead, Zinc and Asphaltite

LAS VEGAS, NEVADA--(Marketwire - Dec. 14, 2010) - Marifil Mines Ltd. (TSX VENTURE:MFM) ("Marifil" or "the Company") announces that an ongoing exploration program for potash in the Neuquen Basin in Argentina resulted in identification of a large area highly favourable for potash in the northern portion of the basin in Mendoza Province.

The Company has acquired by staking six cateos (claims) totalling 47,150 hectares (471.5 square kilometres) that it believes are highly prospective for potash. The claims, the K3 Project, are also prospective for uranium, biogenic sulfur (similar to the Company's Codihue sulfur project), Mississippi Valley type lead and zinc (similar to the Company's Picun Lefu lead zinc project), and for asphaltites (hard bitumens which can, through heating, be a source of petroleum).

Geologic mapping and basin analysis identified this large area as having good potential for salt horizons at depths ranging from 500 m to 2,000 m. The evaporate salt horizons are believed to range from 50 m to 350 m in thickness. Analysis of electric logs from abandoned oil wells is ongoing. Potash (a mineral salt with the chemical formula KCl) typically occurs near the top of thick evaporate salt horizons.

The southern part of the Company's claims lies about 50 kilometers northwest of Vale's giant Rio Potasio potash mine which has a resource of 2 billion tons of potassium chloride.

"Our geologists have had an ongoing program in this region," stated John Hite, President of Marifil Mines. "Their work reveals that this part of the Neuquen Basin has high potential for potash, lead, zinc, uranium, and asphaltite. We are very pleased to have secured these highly prospective claims, one of three of the Company's potash properties, which includes the 80,000 ha K2 project. In keeping with our business plan, the Company intends to farm out or joint venture this property."
