International Northair Mines Intersects 51.45 Metres of 85.70 g/t Silver at La Cigarra, Mexico
International Northair Mines Ltd. (TSXV: INM) (the "Company" or "Northair") is pleased to announce assay results from five diamond drill holes recently completed at its La Cigarra silver project, located in north central Mexico.
San Gregorio Zone Drill Highlights:
Las Carolinas Zone Drill Highlights:
"Step out drilling continues to intersect silver values indicating a strong and potentially surface minable mineralized system comprised of the Las Carolinas and San Gregorio zones," said Fred Hewett, President & CEO of Northair. "The potentially economic mineralization encountered within both zones remains open along strike and down dip. In addition, with only 500 metres of untested ground remaining between the zones, it is highly likely that the two zones are part of the same mineralizing system, representing a continuous strike length of 1.7 kilometres. Good exploration potential also exists to the northwest in the un-drilled intervening ground between the San Gregorio and La Borracha zones; where a further 1.5 kilometres of the structure and a coincident silver soil geochemical anomaly has been identified and remains a priority drill target".
Assays for three additional holes (CC-11-024, 025 and 026) completed within the San Gregorio Zone are pending and will be reported when available.

Note 1: Intervals with silver values greater than 500 g/t reported as 500 g/t.
Note 2: Reported widths may contain intervals with values less than 10g/t silver.
Note 4: Some sections of mineralization carry appreciable lead and zinc values.
Drilling Discussion
San Gregorio Zone:
Holes CC-11-022 and CC-11-023 were drilled as 100 and 200 metre step-outs along strike and south of hole CC-11-007 (77.8 metres of 61.4 silver including 14.0 metres of 221.7 g/t silver) to test for a continuation of the San Gregorio system and associated silver mineralization to the south.
Hole CC-11-022, drilled at -50° on section 3+50S, intersected disseminated and druzy quartz stockwork hosted silver mineralization in siltstones cut by granodiorite to diorite dykes and sills. This geologic setting was similar to that seen in hole CC-11-023, drilled at -50° on section 2+50S.
These drill results confirm that the silver bearing San Gregorio Zone can be traced by diamond drilling on strike for approximately 425 metres (from 0+75N to 3+50S) with this zone remaining open down dip and along strike to the north (towards the La Borracha Zone) and south to the Las Carolinas Zone. The Company now believes that the structure hosting silver mineralization at San Gregorio can be projected under cover to Las Carolinas and both mineralized areas are part of the same large system. Additional drilling will be completed with the objective of joining the two zones.

Las Carolinas Zone:
Holes CC-11-019, 020 and 021 were drilled as step outs to the north of CC-11-016 and CC-11-017 to test a northerly trending silver soil geochemical anomaly.
Hole CC-11-019 was collared at the same location as CC-11-018 (92 metres of 25.8 g/t silver) on section 3+50N, but drilled at -70° to test for possible disseminated quartz stockwork associated silver mineralization below relatively unaltered calcareous siltstones. The hole successfully intersected a zone containing disseminated and druzy quartz vein hosted silver mineralization approximately 180 meters vertically from surface.
Holes CC-11-020 and CC-11-021 were collared in relatively unaltered calcareous siltstones 100 meters further north on section 4+50N. Hole CC-11-020 was drilled at -55° below a silver soil geochemical anomaly and successfully confirmed the continuation of silver mineralization to section 4+50N. Hole CC-11-021 was collared at the same location, but drilled at -70° to test for possible disseminated quartz stockwork mineralization. Similar to hole CC-11-019, silver values were obtained in a package of siltstones intruded by diorite sills measuring approximately 43 meters true thickness. The silver-bearing zone appears to be flattening to the north and east.
To date, drilling in Las Carolinas has identified a silver-bearing zone that can be traced by diamond drilling for approximately 550 metres (from 1+00S to 4+50N). This zone remains open to depth and along strike in both directions. The recent results from sections 3+50N and 4+50N suggests that the holes may have been collared too far east, and further drilling will be necessary in this area to identify a potentially higher grade section of the zone.

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 w ith 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.
