Vancouver, British Columbia, International Northair Mines Ltd. (TSXV: INM) (“Northair” or the “Company”) is pleased to announce that Focus Ventures Ltd. (TSX.V: FCV) (“Focus”) has reported to Northair that an exploration program has commenced at the Company’s El Reventon Property (“El Reventon” or the “Property”), located in the State of Durango, Mexico.

The El Reventon Project was acquired by Northair in 2006, and subsequent exploration identified numerous precious metal occurrences throughout the Property including the Reventon Breccia and the Estrella Zone. Drilling in 2007 and 2008 was concentrated at the Reventon Breccia and returned significant results in silver and associated lead and zinc values.

The recent work carried out by Focus has been concentrated on the Estella Zone, located two kilometres to the southwest of the Reventon Breccia, where a total of 62 samples taken from old underground workings by Focus along a 400 kilometre strike have returned significant grades in silver and associated gold, lead and zinc values.

Additionally, Focus has commenced a detailed soil survey over a 6 x 8 kilometre grid at El Reventon to geochemically map and better define targets such as the Estrella Zone, and generate new targets for follow-up exploration. This technique has proved extremely successful in highlighting new mineralization at Focus’ adjacent Santa Cruz Property.

For details of the agreement between Northair and Focus please see the Northair press release dated April 10, 2012.

Northair also announces that it has executed a binding agreement with a private company to acquire an interest in a significant land position in the vicinity of its La Cigarra Project. The agreement allows the Company to acquire up to a 70% interest in a portion of the land position by paying $525,000 in cash, issuing 1.5 million Northair shares and spending $2 million in exploration over a 4 year period.

This agreement is subject to all necessary regulatory approvals, including the approval of the TSX Venture Exchange.
