Company Retains a 3% Net Smelter Royalty

SPOKANE, WASHINGTON--(Marketwire - Aug. 12, 2010) - MARIFIL MINES LTD. (TSX VENTURE:MFM) ("Marifil" or "the Company") announces that it has signed an agreement with Renholn International, a private company ("Renholn"), whereby Renholn has the right to purchase all of the Company's lithium claims in Salta and Catamarca Provinces, Argentina.

Under the terms of the agreement Renholn agrees to pay Marifil $500,000 in cash at a rate of $125,000 on signing the agreement and $125,000 per year for three years. Renholn further agrees to carry out the $2,250,000 minimum exploration programs recommended in the Company's NI 43-101 reports for these properties at the rate of $500,000 in Year 1; $750,000 in Year 2; and $1,000,000 in Year 3. Marifil shall retain a 3% Net Smelter Royalty.

Renholn shall have three years to obtain a listing on the London AIM market for itself or some other Company ("NEWCO–AIM") that will hold the lithium properties. At the date of the AIM listing, Renholn, or NEWCO-AIM, shall issue $4,500,000 worth of shares in NEWCO-AIM to Marifil at the same price as the initial offering price for such shares.

The lithium properties comprise two claims in Salta Province totalling 19,600 hectares and seven claims in Catamarca Province totalling 19,185.4 hectares.

Mr. John Hite, President of Marifil states, "This is an important milestone for the Company. This deal brings short term value to us in terms of cash for use to carry out other programs, intermediate value in terms of a work program and shares in NEWCO-AIM, and long term value from the 3% Net Smelter Royalty. Renholn is led by a successful mining executive and we are confident that Renholn will make this new company a great success."

The Company will be paying a finder's fee to a third party.
