VANCOUVER, B.C. -- SEPTEMBER 26, 2011, MARIFIL MINES LTD. (MFM: TSX-V) ("Marifil" or "the Company") announces it has initiated a phosphate exploration program in the Neuquen Sedimentary Basin in Mendoza Province, Argentina. The Company has applied for two cateos (mining claims) totalling 7,700 hectares on the basis of reconnaissance sampling results.

The cateos cover a strike length of about 25 kilometres of outcropping phosphatic sedimentary beds included within the Vaca Muerte and Agrio Formations. These rocks are exposed in the Sierra De Reys mountain range and are of Jurassic and Cretaceous age. Marifil now controls about half of the strike length of the favourable outcrops, with its neighbour the giant Brazilian miner Vale S.A. covering the rest.

Marifil's phosphate program is an outgrowth of its potash program within the Neuquen Sedimentary Basin. Company geologists identified phosphate bearing rocks at depth in the basin from examination of oil well drill logs while looking for potash.

A basin analysis including studying the sedimentary depositional environments was made to predict locations where phosphorus would likely precipitate and be concentrated. These beds were then traced to their outcrops along the margin of the basin where geologic mapping and a series of reconnaissance rock chip samples verified the widespread presence of anomalous phosphate.

The phosphate-bearing horizons, named A through E, vary from 5 to 40 meters thick. The Company is mobilizing a more detailed sampling program to include trenching of the identified favourable sedimentary units. Drilling could follow pending further encouraging results.
