Northair Intersects 39.3 Metres of 205.3 g/t Silver at La Cigarra Project, Mexico
International Northair Mines Ltd. (TSXV: INM) (the "Company" or "Northair") is pleased to announce assays results from three diamond drill holes recently completed in the San Gregorio Zone at its La Cigarra silver project, located in north central Mexico.
Drill highlights include:
- 39.3 metres of 205.3 g/t silver in Hole CC-11-009;
- 77.80 metres of 61.4 g/t silver in Hole CC-11-007; and
- 27.20 metres of 50.0 g/t silver and 10.65 metres of 0.303 g/t gold in Hole CC-11-008.
Northair is currently expecting assays from two additional holes drilled in the San Gregorio Zone. While the Company awaits the assays from these holes, drilling continues at the Las Carolinas Zone located 1,000 metres southeast of the San Gregorio Zone. Four holes are immediately planned at Las Carolinas to test along strike and down dip from hole CC-11-005, which returned 48.05 metres of 140.6 g/t silver.

The results from the current drill program clearly demonstrate that significant further drilling at La Cigarra is warranted. The Company plans to continue with an aggressive open-ended diamond drill program to further test the San Gregorio and the Las Carolinas zones; and initiate the first diamond drilling of the La Borracha Zone.
Drilling Summary
Holes CC-11-007, CC-11-008 and CC-11-009 were drilled in the San Gregorio Zone to test for continuity of the silver bearing zone along strike and to depth.
Hole CC-11-007 was drilled on section 1+50S as a 50 meter step out to the southeast from past drilling. The hole intersected a broad mineralized zone highlighted by two intervals of silver-bearing druzy quartz veining and stockwork associated with dyking similar to that noted elsewhere in the zone. This hole has extended the zone 50 meters to the southeast where it remains open along strike.
Hole CC-11-008 was drilled below reverse circulation drill hole CRC-10-011 on section 0+50N to test for continuity of the silver bearing zone to the northwest. This hole was collared within the zone and therefore did not intersect the upper portion of the zone seen along strike to the southeast. The hole intersected druzy quartz veining and stockwork in predominantly bedded siltstones and argillites containing significant silver mineralization in its upper section. In the lower part of the hole a 22.60 meter interval returned elevated gold values including a 10.65 meter interval at the end of sampling which graded 0.303 g/t gold. Similar elevated gold values were also noted in multiple intervals in hole CRC-10-011, including 19.81 meters grading 0.305 g/t gold and 3.04 meters (end of the hole) grading 0.221 g/t gold. This silver and gold zone remains open on strike to the northwest.
Hole CC-11-009 was drilled below CC-11-002 on section 0+00 to test for continuity of the silver bearing zone to depth. This hole was drilled as a 50 meter step-out down dip from CC-11-002, and returned multiple zones with significant druzy quartz veining and stockwork associated with dyking in siltstones between 68.55 and 187.5 meters. The zone remains open to depth, and is the deepest mineralization encountered to date on the property.
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 mineral system with three identified zones along a three kilometre trend. Grupo Northair de Mexico, S.A. de C.A., a subsidiary of Northair, can acquire a 100% property ownership by making payments over a 5 year period totaling US$445,000 with no royalties.
