Marifil Signs Letter of Intent for the K-2 Potash Property

LAS VEGAS, NEVADA -- (Marketwire) -- 12/21/10 -- MARIFIL MINES LTD. (TSX VENTURE: MFM) ('Marifil' or 'the Company') announces that it has signed a Letter of Intent of behalf of itself and Marifil's subsidiary Oxbow Holdings Corp. with Saccharum Energy Corp. (TSX VENTURE: SHM) of Calgary, AB, for the K-2 Potash property in Neuquen Province, Argentina.

Saccharum has agreed to pay $10,000 for an exclusive 60 day due diligence period to check title and further agrees to purchase all of the shares of Oxbow for a price of one cent per share. Marifil then agrees to restructure its underlying agreement with Oxbow whereby Saccharum can earn a 75% interest in the K-2 property.

Saccharum will pay Marifil US$500,000 in cash plus 2,000,000 Saccharum common shares over three years. The first year's payment to Marifil will be US$150,000 in cash and 1,000,000 shares upon Saccharum's completion of a financing.

Saccharum further agrees to spend US$4,500,000 in work over the next four years as follows: US$1,000,000 per year for the first three years and US$1,500,000 during the fourth year.

Saccharum will also pay Marifil performance bonuses of 1,500,000 shares upon completion of a positive NI 43-101 compliant resource and a further 1,500,000 shares following completion of a Feasibility Study. If Saccharum's share structure exceeds 75,000,000 shares during this agreement the shares payable to Marifil shall be adjusted upward proportionately. Upon completion of Saccharm's earn-in all furher expenditures shall be shared 75:25. If a partner fails to pay its share that partner shall be diluted to a 1.5% Net Smelter Royalty. Saccharum shall have the right to purchase Marifil's royalty for US$15,000,000.

Saccharum is also required to restructure its Board by effecting the appointment of Messrs. Todd Montgomery and Brent Walter as directors.

Mr. John Hite remarks, 'We believe this is an important milestone for the Company. Mr. Montgomery was formerly President and CEO of Anglo Potash and Mr. Walter was a director of Anglo Potash. Both men guided Anglo through the discovery and development phase, brought in BHP Billiton to develop the potash deposit, and eventually sold Anglo's remaining 25% of the deposit for US$284,000,000. Bringing these gentlemen onto Saccharum's board will lend credibility to the development of this project.'

Marifil also agreed to give Saccharum Right of First Offer for the Company's K-3 potash project located in neighboring Mendoza Province.

This agreement is subject to approval by the Boards of Directors of Saccharum, Marifil, and Oxbow and the TSX. A small finder's fee is payable to a third party.

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.
