VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 2, 2013) - International Northair Mines Ltd. (News - Market indicators)("Northair" or the "Company") is pleased to announce that Focus Ventures Ltd. (TSX VENTURE:FCV) ("Focus") has reported to Northair that a drill program has commenced at the Company's El Reventon silver-gold property ("El Reventon" or the "Property"), located in the State of Durango, Mexico.

The program, totalling 2,000 metres of core drilling, plans to test a number of targets. Drilling will commence in the Estrella mine area, where at least five mineralized breccias and veins have been discovered over an area of approximately 700 metres long x 250 metres wide. Surface and underground sampling by Focus at the Estrella mine ("Estrella") has shown significant grades of silver and gold including 687 g/t silver over 5.6 metres, with 0.2 g/t gold, 2.6 % lead and 1.3% zinc, and 8.9 metres of 165 g/t silver and 0.32 g/ gold, respectively.

Surface sampling of hydrothermal breccias at the Colorin and La Plomosa areas, located 400 metres east of Estrella, returned 12 meters of 176 g/t silver, 0.2 g/t gold, 3.1% lead and 0.8% zinc; and 6 metres of 78 g/t silver and 0.38 g/t gold, respectively. In addition, sampling at the Chicle Zone, one of several identified mineralized epithermal breccias located approximately 250 metres west of Estrella, returned 4.5 metres of 383 g/t silver and 0.6 g/t gold. 

Focus is also planning drill holes at the Reventon Breccia, where drilling in 2007 and 2008 by Northair returned significant intercepts of silver, zinc and lead within the majority of the completed holes; including 155.4 metres of 71.3 g/t silver, 0.46% lead and 0.61% zinc from hole RC-08-08 and 22.9 metres of 287 g/t silver, 1.39% lead and 3.48% zinc from hole RC-08-13.

Other targets developed by Focus include the Bellota area, where trenching of soil anomalies discovered a new trend of mineralization in altered andesites that assayed 98 g/t silver over 24 metres (see Focus news release October 30, 2012).

The El Reventon Property

El Reventon was acquired by Northair in 2006, and subsequent exploration by the Company 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.

Focus can earn a 65% interest in the El Reventon Project by incurring US$2,000,000 in exploration expenditures over three years, including a firm commitment of US$250,000 in the first year. Focus must also make cash payments to Northair totalling US$235,000 over two years, and maintain all underlying obligations of Northair by making cash payments under an existing option agreement to a property owner totalling US$105,000 (paid). Focus can earn an additional 15% interest by presenting a feasibility study of sufficient quality that would allow Northair to fund its share of the project, plus a cash payment of $100,000.
