SPOKANE, WASHINGTON--(Marketwire - Dec. 21, 2009) - MARIFIL MINES LTD. (TSX VENTURE:MFM) ("Marifil" or "the Company") announces that an independent geological consultant has completed a National Instrument 43-101 report on Marifil's lithium claims (cateos) in Salta Province, Argentina. This report is being filed on SEDAR and is available on the Company website at: [ www.marifilmines.com ].

The Company's four cateos are located within two separate areas -- Salar Llullaillaco and Salar Ratones (see Figure 1 on Company website). The Salar Llullaillaco cateos cover 3,457 hectares while the Salar Ratones cateos cover 19,600 hectares. The properties are located on the Puna plateau, a high basin-like plateau covering portions of Argentina, Chile, and Bolivia. The cateos cover portions of salt lakes (salars) and adjacent alluvial fans. The two Llullaillaco cateos lie along the eastern margin of the Salar Llullaillaco, covering a vast alluvial fan that lies on the eastern margin of the salar. The two Ratones cateos cover part of the Salar de los Ratones.

The Puna plateau contains the majority of the world's largest known lithium-brine resources, making this area attractive to many mineral exploration companies. Lithium brines have been recognized as the lowest cost source for lithium resources. The Puna plateau has been called the "Saudi Arabia of lithium".

The NI 43-101 report recommends a two-phase program for a total cost of $610,000. Phase I, at a cost of $150,000, comprises additional sampling and geophysical work. Phase II, at a cost of $460,000, will include 2,000 meters of drilling. This program should be sufficient to carry out an NI 43-101 compliant ore resource calculation for at least one of the claims.

"The Company has now filed two NI 43-101 reports for these claims and for several groups of claims in neighboring Catamarca Province," stated John Hite, President of Marifil Mines. "In line with our corporate strategy, we now plan to farm out one, or more, of these projects to either well-funded junior resource companies or to Capital Pool Companies (CPC) who are looking for a qualified project. These lithium brine prospects make ideal projects for junior companies because the exploration costs are relatively low, resource calculations can be made quickly, and the capital expenditures necessary to build a plant are generally much cheaper than for a comparably sized gold or base metal project."

For information on the recent NI 43-101 report on the neighboring Catamarca province, please see the Company's press release dated December 14, 2009.

This press release has been reviewed and approved by John Hite, President of Marifil Mines Ltd. and by Richard Walters, Vice President under whose directions the exploration program is being carried out. Mr. Hite and Mr. Walters are Qualified Persons as defined by National Instrument 43-101.
