SPOKANE, WASHINGTON -- SEPTEMBER 29, 2009, MARIFIL MINES LTD. (MFM: TSX-V) ("Marifil" or "the Company") announces that it has acquired seven lithium claims (cateos) in Catamarca Province and two lithium claims in neighboring Salta Province, Argentina.

The claims in Catamarca Province cover an area of about 19,200 hectares. Two of the claim groups cover portions of the Salar de Antofalla and Salar de Ratones which are known as lithium bearing salars. A third group of claims coves parts of the Cachari Pampa Salar; an area where salars border a modern volcano, a good prospective feature in the lithium brine exploration model.

The Company has also signed an agreement with a private individual to purchase a 100% interest in the Mina Rosa II and Mina Rosadita II lithium claims covering an alluvial fan bordering the Llullaillaco salar (dry lake bed) in Salta Province, Argentina.

The Llulluaillaco salar is one of numerous salars marking the Puna Plateau which covers large portions of northwestern Argentina, northwestern Chile, and southern Bolivia. This plateau hosts the largest concentrations of lithium brines in the world.

Under the terms of the agreement Marifil agrees to pay $640,000 over six years to acquire a 100% interest in these claims. The seller retains a 1.5% royalty which the Company can purchase for $800,000.

Assays from a water well located three kilometres southeast of the claims and in the same alluvial fan contain, respectively, 103, 106, and 108 mg/l (milligrams per liter) (1mg/l = 1 ppm = 1g/t) lithium and published samples from other parts of the salar contain 180 to 280 mg/l lithium as well as important amounts of potash and boron. For reference, a lithium brine mine in the United States is producing from brines grading about 150 mg/l lithium.

Lithium is rapidly becoming a strategic metal and demand is expected to increase at an annual rate of 7%. The largest rate of growth will come from lithium used in batteries to power hybrid automobiles.

Company geologists have begun an exploration program to test this property and other salars on the Puna plateau. The Company has mobilized an exploration team to the project area and expects to produce an NI 43-101 report on these properties as soon as possible.

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.
