Marifil Mines Reports New Drill Information from K-2 Potash Project

To Receive NI 43-101 Report for Newly Acquired Potash Property

Marifil Mines Ltd. (TSX - VX: MFM, OTCBB_Pink_Sheets: MFMLF), is pleased to announced today that further to the news release of June 26, 2008, detailed review of the drill hole data confirms economic amounts of potash are present in both drill hole Conin X1 and in drill hole Pillantoqui X1 on the K-2 project. The K-2 project is located in the Company\'s newly acquired, 100 percent owned 100,000 hectare potash property in the Neuquen Basin, Argentina.

Hole Conin X1 (figure 1) contains 5.8 meters grading 15.22% potash (K2O), including 2.0 meters at 20% K2O, and an additional intersect of 5.4 meters of 11.5% K2O. Highlights from hole Pillantoqui X1 (figure 2) include 10 meters of 11.7% K2O and 1.6 meters of 14% K2O. The potash grades are presumed accurate to 0.5 percent. The analysis is based on electric logs of oil well drill holes and is corrected for hole diameter, mud density, and other parameters.

Similarities in the mineralization found in Conin X1 and Pillantoqui X1 (figure 3) suggest a strike of at least 13 kilometers of potash horizon. Marifil has had a consulting geologist on site and expects to receive an NI 43-101 report within the next two weeks.

Mr. John Hite reports, \"This strong correlation between the two holes 13 kilometers apart indicates that we may have discovered a major potash deposit.\"

To date, Marifil has identified two potash horizons in the same basin as Rio Tinto\'s Rio Colorado potash mine. Rio Tinto\'s Rio Colorado mine has a geologic resource of two billion tons of KCl. KCl is the chemical composition of the mineral sylvite, which is highly soluble in water.

This press release has been reviewed and approved by John Hite, President of Marifil Mines 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.
