Northair Provides Update on the El Reventon Project, Mexico

October 31, 2012

International Northair Mines Ltd. (TSXV: INM) (the "Company" or "Northair") is pleased to announce that Focus Ventures Ltd. (TSX.V: FCV) ("Focus") has reported to Northair its initial results from channel sampling recently completed at the El Reventon Property, located in the State of Durango, Mexico. Prospecting and sampling by Focus has confirmed high-grade silver mineralization associated with multiple zones of hydrothermal breccias in areas of strongly anomalous silver-in-soil geochemistry.

The Chicle Zone lies approximately 250 metres west of the Estrella Mine and 2 kilometres southwest of the drilled Reventon Breccia and appears to be one of several mineralized epithermal structures in addition to those sampled at La Estrella, El Taco and Cordon. Recent work along a pronounced north-west trending ridge has revealed a +20 metre wide zone of hydrothermal brecciation in sericitized and chloritized andesites. Initial rock sample results which range from trace to 610 g/t silver and trace to 0.68 g/t gold have validated the strong silver-in-soil geochemical anomaly. The silver mineralization is associated with quartz and arsenopyrite. At El Taco, located 100 metres to the south-east of the La Estrella Mine, sampling along the walls of an old pit assayed 165 g/t silver, 0.32 g/t gold over 8.9 metres. Maps and plans related to these results are available on the Focus Ventures website: www.focusventuresltd.com.

Follow-up trenching of a soil anomaly some 100 metres south of the Bellota occurrence by Focus has outlined a new northeast trending mineralized zone in weakly silicified andesite that assayed 98.3 g/t silver over 24 metres. Focus reports that it believes these results likely represent satellite mineralization to the Reventon breccia where drilling in 2007 and 2008 by Northair cut breccia-hosted silver, zinc and lead in the majority of holes drilled, including 155.4m @ 71.3 g/t silver, 0.46% lead and 0.61% zinc (Hole RC-08-8) and 22.9m @ 287 g/t silver, 1.39% lead and 3.48 % zinc (Hole RC-08-13).

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 will 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$139,000. 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 to Northair.

Sampling Quality Analysis and Quality Control

Rock samples were prepared at ALS Chemex's preparation facility in Zacatecas and analyzed in Vancouver, Canada. Silver was determined by multi-acid digestion and ICP-AES, with fire assay gravimetric finish. Gold was assayed by Atomic Adsorption Spectrometry with fire assay gravimetric finish. Lead and zinc were determined by ICP with Atomic Absorption with volumetric finish. ALS Chemex's quality control system complies with International Standards ISO 9001:2000 and ISO 17025:2005. Analytical accuracy and precision are monitored by the analysis of reagent blanks, reference material and replicate samples. Quality control is further assured by Focus's own QA/QC program which involves the insertion by Focus personnel of blind certified standards and blanks into the sample stream at regular intervals in order to independently assess analytical precision and accuracy of each batch of samples as they are received from the laboratory.
