Northair Sampling at El Reventon Returns Significant Results

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 12, 2007) - International Northair Mines Ltd. (TSX VENTURE:INM) is pleased to provide an update on the El Reventon Project, located in the state of Durango, Mexico. The property was acquired in 2006 following the discovery of the Reventon Breccia, where sampling included 52 metres of 166.5 g/t silver with associated lead and zinc. Exploration crews have been working on the project continuously since last fall, and have discovered numerous other potentially significant silver and base metal occurrences within the property.

Additional reconnaissance sampling has been completed in the La Estrella Zone, located two kilometres to the southwest of the Reventon Breccia. The seven samples in the following table were taken from sparse outcrops of veining and silicified andesite up to approximately 100 meters east of previous sampling.

These results are very significant, and have extended what appears to be a high-grade vein system to a defined strike length of at least 180 meters. It remains open in both directions. Previously announced results from 23 samples taken from the zone reported an average of 372 g/t silver, 0.780 g/t gold, and 2.10% zinc from low sulfidation vein systems. These samples included a six-metre interval (estimated true width of four metres), which returned 740 g/t silver, 0.785 g/t gold, and 2.44% zinc. Of particular interest is the presence of gold, which is absent at the Reventon Breccia and Los Alisos zones.

Two additional zones were recently discovered approximately 400 meters east of the main La Estrella workings. The La Plomosa and El Colorin zones are stockwork and vein systems that may have significant size and grade potential. Samples taken from these zones range between 40.9 and 1185 g/t silver over sample widths ranging from 0.9 to 3.0 metres. Both zones were traced for approximately 100 meters on surface, and are open in both directions. Additional exploration activities, which will include hand trenching, are clearly merited.

Mechanical trenching was recently completed at the Los Alisos Zone with subsequent sample results including 15 metres of 88 g/t silver. The zone appears to be open to the north and east. Los Alisos occurs in diorite porphyry, approximately 500 meters south of the Reventon Breccia. Further exploration will be necessary to determine the ultimate size of the two zones. All of the area between the two targets is covered by post-mineral volcanics, agglomerate and conglomerate. The two zones are geochemically similar, and may be related to the same intrusive.

In March of this year the Company announced they had submitted a solicitude for an additional concession to the west of the project area. Subsequent research at the Direction of Mines in Durango revealed that several individuals had staked a smaller concession in this area prior to Northair. This claim in part lies internal to Northair's additional concession and the Company will need to complete a legal survey to determine the total area acquired.

The Company's exploration program continues to focus on evaluating the entire project area in order to prioritize potential drill targets. The Reventon Breccia remains a high priority target; however, the exciting results from zones such as La Estrella indicate that the project may have several other substantial targets needing further assessment.

Exploration programs in Mexico are supervised by Mr. Jim Robinson, Vice President of the Company, who is a Qualified Person as defined by National Instrument 43-101. The Company maintains a quality control program using best industry practices consistent with NI 43-101.
