International Northair Mines Ltd. (TSXV: INM) and its wholly owned subsidiary Grupo Northair de Mexico, S.A. de C.V. (“Northair” or “the Company”) announces that the Company has signed a binding agreement with Focus Ventures Ltd. (“Focus”) whereby Northair will grant Focus and its subsidiary the option to acquire 65% interest in the Company’s El Reventon Silver Project (the “Project” or “Property”) located in the State of Durango, Mexico.

“Northair is very pleased to have partnered with Focus on the El Reventon project,” said Fred Hewett, CEO & President of Northair. “We look forward to working with Focus in the continued exploration and advancement of this exciting Property.”

The Agreement

The Agreement allows Focus to earn a 65% interest in a joint venture on El Reventon by incurring a cumulative of US$2,000,000 in exploration expenditures over three years from the Agreement Date. The exploration expenditures include a firm commitment of US$250,000 in the first year and at least 2,000 metres of drilling completed within three years from the Agreement Date. Focus will be required to maintain all underlying obligations and make the following cash payments: US$10,000 on signing and completion of a 10 day due diligence period; US$75,000 on or before 12 months of the Agreement Date; and US$150,000 on or before 24 months of the Agreement Date. Once Focus has earned its 65% interest, the Agreement will allow for either party’s interest to be diluted for non-participation in the joint venture. Should either party’s interest fall below a 10% threshold, its interest will be converted to a 1% net smelter return (“NSR”). The Agreement is subject to certain legal due diligence by Focus and to receipt of any necessary regulatory approval.

El Reventon Project:

The El Reventon Project was acquired by Northair for its potential to host economic quantities of silver with significant by products of lead, zinc and gold. The Project is located approximately 170 kilometres northwest of Durango, Mexico, and lies within a major mineral belt that hosts numerous important mines and districts including Bacis, Montoros, Metates, La Cienega and Topia.

The El Reventon property covers a series of mineral occurrences contained within a belt of Upper Jurassic metasedimentary rocks overlain by Tertiary aged volcanics. In 2006, 51 initial surface channel samples taken by Northair from the Reventon Breccia target averaged 104 g/t silver; highlights included 52.0 metres of 166.5 g/t Ag, 0.73% Pb, 0.85% Zn.

In 2007, Northair completed six core holes as an initial test of the Reventon Breccia. Potentially important mineralization was identified and as a follow-up of this target, 15 RVC holes were completed in 2008. This second phase drill program was successful in expanding the mineralized zone with 12 of the 15 holes drilled here intersecting significant silver values. Highlights of the drilling include 120.4 metres of 100.9 g/t silver and 91.4 metres of 97.0 g/t silver. Exploration potential of the Property is very encouraging, as the most southeast drill hole from phase two bottomed in 9.1 metres of 141.5 g/t silver.

In addition to the Reventon Breccia, the Company has sampled a number of other zones on the property all of which are identified by historic prospects and mines, some possibly dating back to the Spanish. One of these zones, Los Alisos, has a geochemical signature similar to the El Reventon Breccia and is located approximately 500 metres to the south. The area between these two mineralized zones is covered by post-mineral volcanics with the connecting area remaining a priority drill target. During the 2008 drill program, two holes were drilled at Los Alisos with one hole reporting 16 metres of 36.8 g/t silver, 0.5% Pb and 2.46% Zn. Other exploration targets on the property include the El Portrero Zone (sixty-one samples averaged 23 g/t silver over widths from 1.5 to 7 metres) Portrero East and the La Estrella Zone (twenty-four samples averaged 0.825 g/t gold and 385 g/t silver over sample widths from 0.75 to 5 metres).

The El Reventon property consists of 3,370 hectares and the Company has an option agreement to acquire an additional 60 hectare internal concession by paying US$139,000 over a four year period.
