Northair Reports 34.8 Metres of 192 g/t Silver From Trenching at Sierra Rosario Project, Mexico; Drill Program Planned
International Northair Mines Ltd. (TSXV: INM) (the "Company" or "Northair") and Sparton Resources Inc. (TSX: SRI.V) are pleased to announce results from a recently completed trenching and surface sampling program at the Sierra Rosario Project located in the state of Sinaloa, Mexico. Highlights of the program include 34.8 metres of 192 g/t silver with 0.22 g/t gold; and 27 metres of 91.8 g/t silver with 0.15 g/t gold from the San Rafael Zone. Drilling of the zone is planned in the fall.
The Sierra Rosario Project is comprised of at least six significant zones of precious metal mineralization, including the San Rafael Zone and the recently discovered Descubriadora and Dulces Nombres Zones in the northern portion of the property.
An access road was recently constructed to the San Rafael Zone and the area of the other newly discovered zones. This road allowed mechanical trenching to be completed and will facilitate the fall drill program. A total of 321 samples were taken in 20 sample lines from outcrops in roads and trenches throughout the San Rafael Zone. Samples were generally continuous 3 metre chips, with results summarized below:

The San Rafael Zone contains a granodiorite porphyry intruding limestone and siltstone overlain by andesite volcanics. The porphyry is an irregular shaped body on surface measuring approximately 250 by 120 metres. Within the granodiorite are numerous moderate to high-angle faults that locally influence higher grades of mineralization. Mineralization occurs as veins, stockwork and dissemination throughout the porphyry and is also locally evident in both the volcanics and sediments. Of particular interest is Sample Line 1 (see Summary Table) in andesite volcanics, which returned 15 metres of 1.07 g/t gold. Skarn mineralization also exists approximately 175 metres to the southeast of the intrusive body, with 17 select panel and float samples returning values ranging from background to a high of 3.80 g/t gold and 882 g/t silver. There appears to be excellent potential that the San Rafael Zone could be far more extensive than the present surface exposure and drilling will be required to establish the grades and geometry of the intrusive at depth.
The project is being explored by a joint venture with Sparton Resources Inc. who has recently earned a 51% interest in the project by completing cash payments of $130,000, and issuing 275,000 common shares to Northair while incurring $800,000 in exploration expenditures. Northair is the manager of the program through the completion of a first phase of drilling, which is scheduled for the fall of 2008.
The current phase of the program is being supervised by Mr. Jim Robinson, Vice President of the Company, who is a Qualified Person as defined by National Instrument 43-101. Northair maintains a quality control program using best industry practices consistent with NI 43-101. Samples reported in this release were submitted to ALS Chemex Labs in Hermosillo, Mexico, with gold assayed by a 50 gram digestion with fire assay - atomic absorption finish. Silver and other elements were assayed by aqua regia acid digestion with ICP finish. Silver samples reporting over 100 ppm were re-assayed by atomic absorption finish.
