NORTHAIR INTERSECTS 7.5 METRES OF 179.3 G/T SILVER AT SIERRA ROSARIO PROJECT, MEXICO
International Northair Mines Ltd. is releasing assay results from six core holes completed in the San Rafael zone at its Sierra Rosario silver-gold project, located in Sinaloa state, Mexico.
During the month of June, six diamond drill holes, totalling 1,392.15 metres, were drilled in the northwestern section of a coincident induced-polarization geophysical anomaly and silver/gold geochemical soil anomaly. The holes were designed to test only 30 per cent of the anomalies as well as a small portion of the area which had returned encouraging silver and gold values from trench sampling.
The most significant drill results were obtained in hole SR-003, where a 7.5-metre interval returned 179.3 grams per tonne silver and 0.287 gram per tonne gold, and a 4.9-metre interval assayed 66.7 grams per tonne silver and 0.614 gram per tonne gold. In hole SR-005, located approximately 400 metres to the southeast of hole SR-003, a 3.35-metre interval returned 84.1 grams per tonne silver, 0.102 gram per tonne gold and 1.59 per cent lead.

Concurrent with the drill program, a follow-up soil-sampling program was completed which was designed to extend the existing soil sampling grid to the south and to the northeast. This open-ended silver/gold soil anomaly currently measures 1,400 metres in length and 1,300 metres wide. Three lines added to the southeast reported no significant results, but sampling to the northeast saw an expansion in this still-open direction. The company and its joint-venture partner are presently evaluating the results of the recent program in anticipation of completing further follow-up work on the property.
Sampling and quality assurance/quality control
All technical information for the Sierra Rosario exploration program is obtained and reported under a formal quality assurance and quality control program. Samples are taken under the direction of qualified geologists and stored in sealed bags. Samples are delivered by the company by courier to ALS Minerals in Chihuahua. The samples are dried, crushed and pulverized, with the pulps being sent air freight for analysis by ALS to Vancouver, B.C. 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.
