SPOKANE, WASHINGTON--(CCNMatthews - Aug. 07, 2007) - MARIFIL MINES LTD. (TSX VENTURE: MFM.V) ("Marifil" or "the Company") announces preparations are underway for the launch of a new round of drilling at the Company's San Roque project, Rio Negro Province, Argentina (see Marifil News Release dated June 18, 2007.) Plans for this Phase 2 drill program include 2,500 metres (m) of diamond core plus 2,500 m of rotary drilling. The drill program is expected to begin as soon as mid-September, which is early spring in the southern hemisphere.

Phase 2 Drill Program

The two immediate objectives are to:

1. Expand the testing of extensive and open zones of high-grade levels of indium (In), gold (Au) and/or base metals, particularly zinc (Zn) and lead (Pb) previously identified by drilling by either the Company or MIM Exploraciones S.A. (a wholly-owned subsidiary of mining giant XSTRATA.)

2. Complete initial drilling on number of newly identified areas that surface geochemical sampling and mapping show to be prospective for similar base metal/indium mineralization.

"In our last round of drilling earlier this year, we generated some of the highest indium assays ever seen. Moreover, it is nicely enclosed within a huge zone of zinc mineralization. We are naturally very eager to expand the drilling and find out just how big and strong this thing is," said Marifil President and CEO, John Hite. "We are convinced that San Roque will turn out to be a very exciting find and we need to complete more drilling to provide the proof."

Additional Indium Assays

Marifil now has possession of drill core generated by an 8-hole diamond drill coring program conducted on San Roque by MIM in 2001/02, MIM had not previously assayed for In and Marifil is now quartering the mineralized sections of these drill cores and submitting these samples for In assaying. This previous MIM drilling revealed extensive high-grade Zn approximately 1,100 m southeast of the Del Indio structure. In particular, the Company will send for assay quartered core samples from MIM's diamond drill hole number eight (DDH-8), which cut 54 m (depth: 130-184 m) of 1.1% Zn and 0.5% Pb, including 14 m (138 - 152 m) of 3.2% Zn and 1.5% Pb, and 8 m (40-48 m) of 4.8% Zn and 2.0% Pb.

Marifil is looking to test the interesting coincidence that it has noted in this geological environment between high levels of Zn and strong In mineralization. Results from these new assays, which will be processed at the Alex Stewart Laboratory in Mendoza, Argentina, are expected to take four to six weeks.

San Roque Property: The Company has the right to earn a 100% interest (see Marifil news release dated June 18, 2007) in the 12,700 hectare San Roque project, where strong mineralization has been found within a structural corridor at least 10 kms wide and 20 kms long. Marifil's exploration work includes a Phase 1 28-diamond drill hole (DDH) program that intercepted high-grade Indium (In), Zinc (Zn), Silver (Ag) and Gold (Au), along with other base metals, particularly Lead (Pb). These intercepts include 5.1 meters of 2.61 g/t Au; 24 g/t Ag; and, 30.4 g/t In in DDH 11 and 0.75 meters of 2.05 g/t Au; 0.22 % Pb; 0.32% Zn; and, 448 g/t In. in DDH 7, and 117 m of 0.95% Zn in DDH 4 including 4.5 meters of 0.37 g/t Au; 499 g/t In and 6.64% Zn. Marifil's management recognizes that the property has bulk tonnage base metal potential.
