SPOKANE, WASHINGTON–( EMWNews – April 7, 2008) – Marifil Mines Ltd. (TSX VENTURE:MFM) is pleased to announce results from its second round of drilling on the company’s wholly owned San Roque base metal project, in Rio Negro Province, Argentina. Drill holes 52 to 55 have continued to cut long intercepts of base metals along with gold-silver-indium (see news release dated January 8, 2008). The mineralization is indicative of a porphyry type disseminated sulphide system that is believed to be up to three kilometres in diameter.

Previously, silver values were not reported for drill hole 51. In this round of drilling, hole 51 cut 143 meters (m) of 0.66 grams per ton (g/t) gold, 27.2 g/t silver, 0.37% lead and 0.55% zinc. Drill hole 52 cut 127.8 m grading 0.22% lead and 0.40% zinc. Drill hole 53 cut 26.0 m grading 0.24% lead and 0.62% zinc. Drill hole 55 cut 75.6 m grading 0.12 g/t gold, 3.9 g/t silver, 0.26% lead and 0.81% zinc, followed by 5.8 m grading 0.37% lead and 0.58% zinc, followed by 13.7 m grading 0.4% lead and 0.82% zinc, followed by 25.3 m grading 0.43% lead and 0.89% zinc.

This second round of drilling produced significant intercepts of combined gold, silver, indium, lead and zinc values in all 16 holes, as illustrated in Table 1.

“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. As a result, we have now identified significant amounts of disseminated base metals over a zone measuring 1,700 m in a northeast-southwest direction and 2,400 m in a northwest-southeast direction. Mineralization is open-ended in every direction, including at depth.”

The company is currently analysing the new drilling information in conjunction with new geophysical survey results and is planning a third round of drilling of at least 10,000 m to further probe the vast sulphide system. All 55 holes drilled so far contain significant amounts of gold, silver, indium, lead, and zinc. Marifil’s exploration model is similar to Goldcorp Inc.’s world-class Peñasquito deposit in the state Zacatecas, Mexico.
