Northair Intersects 170.4 g/t Silver Over 17.9 Metres at La Cigarra Project, Mexico

September 18, 2012

International Northair Mines Ltd. (TSXV: INM) (the "Company" or "Northair") is pleased to announce the assay results from nine core holes completed in the San Gregorio Zone at its La Cigarra silver project, located in north central Mexico.

"The latest infill drill results from the San Gregorio Zone continue to be positive and provide important data to the Company for the Resource calculation currently in progress," said Fred Hewett, President & CEO of Northair. "We are particularly encouraged by the drill results located at the northern end of the zone, which indicate the continuation of an open robust mineralized system trending northwest towards the La Borracha Zone.

Drill Highlights from the San Gregorio Zone Infill Program:

  • Hole CC-12-082A intercepted 18.60 metres of 22.0 g/t silver. This hole was an attempt to complete Hole CC-12-082 which was lost due to heavy faulting before reaching the target zone. Drilling once again did not reach the intended depth, but did encounter mineralization prior to stopping short of the target zone.
  • Hole CC-12-085 intercepted 57.00 metres of 34.2 g/t silver including 26.10 of 57.5 g/t silver;
  • Hole CC-12-086 intercepted 38.90 metres of 88.2 g/t silver including 17.90 meters of 170.4 g/t silver;
  • Hole CC-12-087A intercepted 9.00 metres of 29.1 g/t silver and 1.30 metres of 106.0 g/t silver;
  • Hole CC-12-088 returned three intercepts of 3.70 metres of 140.9 g/t silver, 15.50 metres of 73.8 g/t silver and 18.30 metres of 55.2 g/t silver;
  • Hole CC-12-090 returned three intercepts of 3.00 metres of 44.2 g/t silver, 3.50 metres of 34.0 g/t silver and 11.55 metres of 127.4 g/t silver including 5.55 metres of 249.5 g/t silver;
  • Hole CC-12-092 returned four intercepts of 8.10 metres of 29.6 g/t silver, 2.80 metres of 27.7 g/t silver, 11.60 metres of 24.8 g/t silver and 9.00 metres of 46.8 g/t silver;
  • Hole CC-12-094 returned three intercepts of 27.55 metres of 69.3 g/t silver, 8.55 metres of 65.8 g/t silver and 10.90 metres of 46.2 g/t silver;
  • Hole CC-12-095 intercepted 13.10 metres of 35.1 g/t silver.

Northair has now completed the first portion of its 2012 core program at La Cigarra. Results have been released for 99 of 118 core holes with all of the drilling thus far reporting appreciable mineralization over significant widths. Assays for the remaining 19 core holes (all completed in the Las Carolinas Zone) will be released once results are received and interpreted. Since the first drill program was carried out on the property in 2010, the Company has completed 133 drill holes totalling 21,953.5 meters, including 15 reverse circulation holes and 118 HQ sized core holes. Further drilling is anticipated to commence in the fall after the rainy season to continue to test the San Gregorio and Las Carolinas zones, as well as targets generated from the current field program.

Exploration Update

Northair is currently conducting a field program at La Cigarra while it awaits the end of the rainy season. The program includes geological mapping, soil sampling and reconnaissance outcrop sampling over prospective areas of the property to expand the geological knowledge and provide additional drill targets. The Company also continues to compile data from the recently completed core drill program into order to calculate a 43-101 compliant Resource Estimate within Q4 2012.

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,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.
