Northair Intersects 32.0 metres of 132.4 g/t silver at La Cigarra Silver Project, Mexico
International Northair Mines Ltd. (TSXV: INM) (the "Company" or "Northair") is pleased to announce assay results from the first 11 of 15 drill holes from its phase I drill program recently completed at the La Cigarra silver project, located in north central Mexico. The drill program, totaling 1,455 metres in 15 reverse circulation drill holes, was successful in testing the top two priority targets on the property; the Las Carolinas and San Gregorio Zones. Drill results for a lower priority zone identified along the 3 kilometer mineralized property trend, the La Borcha Zone, are pending and are expected to be released shortly.
Drill highlights of the program to date include 32 meters of 132.4 g/t silver in Hole CRC-10-06 at the San Gregorio Zone and 10.7 metres of 172.5 g/t silver in Hole CRC-10-01 at the Las Carolinas Zone. Drilling tested a 300 metre length in each zone and the zones remain open along strike and down dip. Drill holes were laid out to intersect the zones at close to an optimum angle, but reported mineralized widths are less than true widths.
"We are extremely pleased with the results from this initial drill test of our La Cigarra silver project," said Fred Hewett, President & CEO of Northair. "Significant further exploration will be necessary to ascertain the projects ultimate potential, but this is a very positive first step in that process."

*Holes CRC-10-7 and 8 did not adequately test the mineralized zone due to intersecting old workings.
A significant number of the reported intercepts also returned anomalous lead and zinc values, which further strengthens the project's possible geological similarities to the producers of the Parral region. Multi-element geochemical analysis from the drilling has confirmed that La Cigarra hosts classic low sulfidation silver-gold mineralization and associated trace element geochemistry. The silver-lead mineralization correlates strongly with antimony and to a lesser extend with lead, zinc, copper, barium, manganese and arsenic. Further analysis of the drilling data will be undertaken to ascertain zoning relationships between silver and its known associated trace elements; in order to focus on further exploration. Selected portions of certain drill holes were analyzed for gold and returned anomalous values and additional analysis will be carried out.

Drilling was carried out to confirm surface values, geology, and provide a framework to decide upon the future direction of exploration on the property. The drilling intercepted significant widths of altered and mineralized sediments of volcanics and follow up drilling is warranted.
Project Summary
The La Cigarra silver project is located in State of Chihuahua along the eastern fringes of the Sierra Madre Occidental in Mexico. Local topography is gentle with good road access to the major city of Parral, located 26 kilometres to the south east. The La Cigarra Project hosts a silver-rich, epithermal mineral system that is controlled by a northwest striking fault system that has localized silver (lead, zinc, copper and gold) mineralization hosted in sediments and related to rhyolite dikes and flows. La Cigarra has witnessed limited mining and prospecting with no previous apparent drilling along this northwest striking structural trend. Surface sampling from the Company during 2009 and 2010 was successful in highlighting three mineralized centers, and the recent reverse circulation drill program focused on these zones. Grupo Northair de Mexico, S.A. de C.A., a subsidiary of Northair, can acquire a 100% property ownership by making payments over a 5 year period totaling US$445,000 with no royalties.
The grades from the initial surface sampling reported at La Cigarra appear to be similar in scale to those of the Santa Barbara-San Francisco del Oro sub-districts of Parral that have produced over 440 million ounces of silver. Although La Cigarra has probably had very limited silver production, the Parral Region in total has produced over one billion ounces of silver and over one million ounces of gold, placing it in the top ten silver districts in Mexico.
All technical information for the La Cigarra drill program is obtained and reported under a formal quality assurance and quality control (QA/QC) program. Samples are taken by qualified geologists and stored in sealed bags. Samples are picked up on site by ALS Chemex Labs and taken to Chihuahua for drying, crushing and pulverizing; with the pulps sent by airfreight to ALS Chemex in Vancouver BC for analysis. Systematic assaying of standards and blanks are performed for precision and accuracy. Analysis for silver, zinc, lead and copper was done by ICP four acid digestion, with selected gold analysis by 30 gram fire assay with an AA finish.
