VANCOUVER, BRITISH COLUMBIA, Feb 28, 2012 (MARKETWIRE via COMTEX) — International Northair Mines Ltd. (the “Company” or “Northair”) is pleased to announce assay results from eight core drill holes recently completed in the San Gregorio Zone at its La Cigarra silver project, located in north central Mexico.

Highlights of the Continuing Drill Program

 — Hole CC-11-045, drilled 200 metres southeast of hole CC-11-038 (33.75

metres of 101.1 g/t silver) intercepted 16.45 metres of 127.4 g/t silver

including 7.60 metres of 230.0 g/t silver and successfully extended the

southern projection of San Gregorio mineralization by 200 metres. Hole

CC-11-045, along with CC-11-046 are currently the most southern holes

drilled in the San Gregorio Zone;

— Holes CC-11-047 and 048 were drilled 50 and 100 metres northwest of CC-

11-035 and successfully extended the mineralized strike length of the

zone by 100 metres to the north. Hole 48 is currently the most northern

hole drilled in the San Gregorio Zone.

— Holes CC-11-041, 042 and 043 were all drilled to test the up dip

projection of known mineralization and provide further information for

the upcoming resource calculation. All of these holes were successful,

highlighted by:

— 24.80 metres of 59.5 g/t silver in hole CC-11-041;

— 26.45 metres of 39.3 g/t silver in hole CC-11-042; and,

— 26.90 metres of 56.0 g/t silver in hole CC-11-043.

— Hole CC-11-044, positioned between Hole CC-11-038 and CC-11-045,

intercepted 13.00 metres of 16.3 g/t silver and encountered (at the

bottom of the hole) a 1.00 metre high grade interval containing a

massive chalcopryrite vein returning 306.7 g/t silver and 5.3 % copper;

“We are very pleased by our drilling as results continue to expand the potentially surface minable mineralized system on the Property,” said Fred Hewett, President & CEO of Northair. “The San Gregorio and Las Carolinas Zones have now been drilled over a strike length totaling 1.9 kilometres. Exploration upside of this mineralized system remains excellent as both zones remain open along strike and down dip, providing the Company with significant potential to expand the mineralization for the upcoming resource calculation scheduled to be released in 2012.”

To date, Northair has reported 48 diamond drill holes completed at La Cigarra totaling 9,750 metres in length. Continued drilling on the Property will be focused on infill drilling within the San Gregorio and Las Carolinas zones and step out drilling to test the intervening prospective areas between the San Gregorio and Las Carolinas mineralized zones. Since drilling recommenced in 2012, the Company has completed an additional seven holes within the San Gregorio Zone. The results for all future drill holes will be reported once the Company has received and interpreted the results.

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 Chemex Labs in Chihuahua for drying, crushing and pulverizing; with the pulps sent airfreight by ALS Chemex to Vancouver B.C. for analysis. 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 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.
