Marifil Mines Ltd.: Encouraging Drill Results From San Roque

PORPHYRY-STYLE INDIUM, PRECIOUS AND BASE METALS SYSTEM IDENTIFIED

SPOKANE, WASHINGTON--(Marketwire - Jan. 18, 2008) - MARIFIL MINES LTD. (TSX VENTURE:MFM) ("Marifil" or "the Company") announces that drill holes 50 and 51 both cut long intercepts of base metals along with gold (see MARIFIL NEWS RELEASE dated January 8, 2008) in the Company s wholly owned San Roque base metal project, located in Rio Negro Province, Argentina. The mineralization is indicative of a porphyry type disseminated sulphide system thought to be over four kilometres in diameter.

Hole 50 cut 122.6 metres (m) at 0.34 grams per ton (g/t) gold including 93 meters at 0.30% lead and 0.50% zinc. Hole 51 cut 126 m of 0.74 g/t gold within a section of 143 meters grading 0.37% lead and 0.55% zinc. All sixteen holes from this second round of drilling produced significant intercepts of variously combined gold, silver, indium, lead and zinc values, as illustrated in Table 1.

Mr. John Hite, President of Marifil says, San Roque continues to look like a huge discovery. As we step-out away from the discrete linear structures tested by our previous drilling, we are encountering broad zones of gold and base metal mineralization, typified by holes 50 and 51.

The Company is analysing the new drilling information in conjunction with new geophysical survey results, and is already planning a third round of drilling of at least 10,000 meters to further probe the vast sulphide system. All 51 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 Penasquito deposit in Zacatecas State, Mexico.
