Marifil Receives Extension for San Roque Payment

SPOKANE, WASHINGTON--(Marketwire - May 19, 2010) - MARIFIL MINES LTD. (TSX VENTURE:MFM) ("Marifil" or "the Company") announces that MIM Argentina Exploraciones S.A. (a wholly owned subsidiary of Xstrata) has granted the Company a two year extension on a $400,000 purchase price for the key claims of the San Roque project, Rio Negro Province, Argentina.

Under the original agreement Marifil agreed to spend a minimum of $200,000 on exploration over four years and make a single payment of $400,000 to purchase the claims. The work expenditures have all been met; however, owing to the world-wide financial turmoil over the past several years, Marifil requested a two year extension on the cash payment and MIM has graciously agreed.

About San Roque

The Company believes that San Roque is a giant sulfide system hosted within a caldera measuring at least 3 kilometers wide and up to 4.5 kilometers long. Marifil has drilled 51 holes and all contain significant amounts of gold, silver, indium, lead, and zinc. Notably, Hole 50 cut 122.6 metres (m) at 0.34 grams per ton (g/t) gold from 24.4 m to 147 m and Hole 51 cut 126 m of 0.74 g/t gold from 7.0 m to 133.0 m. Both holes also cut significant amounts of silver, indium, lead, and zinc.

These two drill holes are significant as they are located about 1,200 m southeast of the Del Indio breccia target and cut similar rocks. The significance is that the gap between is highly prospective; a theory bolstered by both Induced Polarization and soil geochemical anomalies.

"We continue to believe that San Roque is a huge discovery," stated Mr. John Hite, president of Marifil Mines. "Our initial two rounds of drilling focused on testing indium and gold-bearing epithermal veins. Mineralization is open-ended in every direction, including at depth."

MIM also granted the Company a similar two year payment extension for a claim peripheral to the Company's discovery claims at the Toruel project in Rio Negro Province. Drilling at Toruel has discovered bonanza grade copper-silver-indium in epithermal breccias.
