Vancouver, B.C. � October 12, 2012, MARIFIL MINES LTD. (TSX-V: MFM) (�Marifil� or �the Company�) is happy to announce that it has resumed operatorship of the Las Aguilas property. Marifil and Prophecy Platinum Corp. (TSX-V: NKL) have terminated their Joint Venture earn-in option on the Las Aguilas property, San Luis Province, Argentina.

 Marifil has begun discussions with an Argentinean company that is interested in forming a partnership to develop the property.

 John Hite, President of Marifil, comments: �While we are disappointed that Prophecy Platinum has elected not to move forward with Las Aguilas, we remain excited about the property and the opportunity to form a new partnership. Since Las Aguilas has a 43-101 (Wardrop Engineering) indicated plus inferred resources containing a minimum of 18,871 tonnes of copper, 18,796 tonnes of nickel, 1,381 tonnes of cobalt and 1,222,670 ounces of platinum plus palladium, we remain encouraged about its near-term development possibilities.
