VANCOUVER, BRITISH COLUMBIA, Jul 23, 2012 (MARKETWIRE via COMTEX) — International Northair Mines Ltd. /quotes/zigman/186633 CA:INM +2.00% (the “Company” or “Northair”) is pleased to announce the results from six core holes completed in the San Gregorio Zone at its La Cigarra silver project, located in north central Mexico.

Drill Highlights from the San Gregorio Zone:

 — Hole CC-12-79 returned intercepts of 12.30 metres of 55.4 g/t silver and

5.25 metres of 19.9 g/t silver. This hole tested the up dip projection

of hole CC-11-033 which returned intercepts of 25.50 metres of 40.4 g/t

silver and 20.75 metres of 38.5 g/t silver;

— Hole CC-12-80 intercepted 52.25 metres of 167 g/t silver, which included

34.75 metres of 241.2 g/t silver. This hole extended the silver zone

approximately 50 metres down dip from hole CC-11-010 which returned

intercepts of 95.50 meters of 77.4 g/t silver and 40.80 metres of 37.4

g/t silver;

— Hole CC-12-081 returned an intercept of 10.60 metres of 30.3 g/t silver.

This hole tested the up dip projection of hole CC-11-007 which returned

intercepts of 5.80 metres of 23.0 g/t silver and 77.80 metres of 61.47

silver;

— Hole CC-12-083 returned intercepts of 56.00 metres grading 105.7 g/t

silver, which included 20.90 metres of 241 g/t silver and 6.20 of 84.3

g/t silver. This hole extended the down dip projection of hole CC-12-080

to a depth of approximately 300 meters;

— Hole CC-12-084 intercepted 39.90 metres of 52.1 g/t silver, testing the

up dip projection of hole CC-011-031 which returned 54.30 metres of 36.9

g/t silver.

“We continue to be very pleased with the exploration success at La Cigarra,” said Fred Hewett, President & CEO of Northair. “Holes CC-12-080 and 83 are among the deepest drilled to date on the property with the results confirming that significant silver mineralization exists upwards of 300 metres below surface. This area within the San Gregorio Zone remains open along strike and down-dip to the northeast where it extends beneath a large alteration zone mapped on surface.”

Background

The Company had originally intended to curtail drilling at the end of June in order to calculate its first resource calculation for La Cigarra. However, as a result of the continued drilling success, Northair has extended its drill program into July with the addition of 14 holes. The resource calculation is now scheduled for the 4th Quarter of 2012.

The San Gregorio and Las Carolinas zones have been the main focus of the current drill program at La Cigarra where drilling has identified a strong mineralized system along a 2,300 metre strike length that remains open along strike and down dip. To date, Northair has reported results from 83 of 117 core holes drilled. Results for completed holes will be reported by the Company once assays have been received and interpreted.

Sampling and QA/QC

All technical information for the La Cigarra exploration program is obtained and reported under a formal quality assurance and quality control (QA/QC) program. Samples are taken under the direction of qualified geologists and stored in sealed bags. Samples are delivered by the Company via courier to ALS Minerals (“ALS”) in Chihuahua and Inspectorate America Corporation (“Inspectorate”) in Durango City. In both cases the samples are dried, crushed and pulverized with the pulps being sent airfreight for analysis by ALS to Vancouver B.C. and by Inspectorate to Vancouver B.C. or Reno, Nevada. Systematic assaying of standards and blanks are performed for precision and accuracy. Analysis for silver, zinc, lead and copper and related trace elements was done by ICP four acid digestion, with gold analysis by 30 gram fire assay with an AA finish.

About the La Cigarra Silver Project

The La Cigarra Project is located in the 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 vein system with three identified zones forming a three kilometre trend.
