International Northair Mines Ltd. (the "Company" or "Northair") is pleased to report that it has completed a surface trenching program as part of its ongoing surface exploration program at its La Cigarra silver project (the "Property"), located in north central Mexico.
The trenching program was primarily designed to investigate the potential of the northern portion of the San Gregorio Zone where a number of very positive drill holes from the 2012 drill program were not included in the published resource calculation and are outside the NI 43-101 Whittle Pit (see press release #13-08 dated April, 11th, 2013). Trenching results as tabulated below are very encouraging and point to the significant potential to expand the resource with further drilling:
- Trench SG 4+00N returned intervals of 34.5 metres of 49.1 g/t silver including 7.1 metres @ 153.5 g/t silver, and 36.7 metres of 15.9 g/t silver;
- Trench SG 3+50N returned three intervals of 12 metres of 72.0 g/t silver, 5.4 metres of 22.8 g/t silver and 4.5 metres of 24.2 g/t silver;
- Trench SG 2+00N returned 63.1 metres of 49.6 g/t silver including 13.55 metres of 75.5g/t silver and 5.7 metres of 38.1 g/t silver;
- Trench SG 1+50S returned 6 metres of 125.8 g/t silver and 14.4 metres of 29.3 g/t silver.
Geological mapping was conducted in conjunction with the trenching program and identified a previously unrecognized intrusive rhyolite that hosts silver mineralization in its outer margin and could be one of the heat sources that produced the mineralized La Cigarra system.
During the mapping program, Northair geologists found a previously unknown underground adit north of trench SG 4+00N. Sampling of this adit returned intervals of 7.5 metres of 155.4 g/t silver and 16.2 metres of 46.8 g/t silver. Values occur in the intrusive and highlight the importance of the discovery.
The results from the surface mapping, trenching and sampling program clearly indicate that the silver mineralization in the San Gregorio Zone remains open at surface to the north and east outside the published resource and further drilling is warranted.
Resource Expansion Potential in San Gregorio and La Borracha Zones
In conjunction with the surface program, a complete review of all the 2012 drilling conducted in the northern part of the San Gregorio Zone was undertaken. The review revealed that a significant number of drill holes with positive results in the area were not included within the constrained pit of the current resource. Results from these drill holes are highlighted by the following intercepts:
- CC-12-135 on section SG2+00N intercepted 6.5 metres of 765 g/t silver, 13.10 metres of 32.2 g/t silver and 8.0 metres of 178.0g/t silver;
- CC-12-138 on section SG1+50N intercepted 24.2 metres of 150.9 g/t silver and 4.3 metres of 31.7g/t silver:
- CC-12-133 on section SG4+00N intercepted 3.0 metres of 61.8 g/t silver and 21.2 metres of 61.5 g/t silver.
The Company believes the potential to expand the current resource in San Gregorio to the north and to the east with further drilling is excellent.
In addition to trenching at San Gregorio, the Company also conducted surface work at the La Borracha Zone, located approximately one (1) kilometre to the northwest of San Gregorio. Positive results from this program are highlighted by trench SG 15+00N, which returned 4.5 metres of 119.5 g/t silver. These results show that the mineralized system remains open to the north at the presently known northwestern end of the La Borracha Zone. This trench along with nine (9) previous drill holes that have intercepted significant silver mineralization along the one (1) kilometre trend of the system in La Borracha support the expansion potential of the current resource estimate at La Cigarra.
Continuing Exploration at La Cigarra:
The Company continues with its field programs designed to expand the known open 6 kilometre mineralized trend and plan for additional drill programs along strike from the published NI 43-101 Resource. Exploration includes further geological mapping and sampling along with soil and silt geochemical surveys. Northair will provide updates of the programs as results become available.
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 Minerals ("ALS") in Chihuahua where they are dried, crushed and pulverized with the pulps being sent airfreight for analysis by ALS to Vancouver B.C. 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 International Northair Mines Ltd.
Northair is a mineral exploration company engaged in the acquisition and development of gold and silver properties in Mexico. International Northair Mines Ltd.is focused on advancing its La Cigarra silver project located in the state of Chihuahua, which currently hosts a NI 43-101 Resource estimate of 50.4 million ounces of silver in the Measured & Indicated categories grading 76 g/t silver and 3.5 million ounces of silver in the Inferred category grading 61 g/t silver constrained by a Whittle pit shell at an economic cutoff grade of 30 g/t silver (assuming metallurgical recoveries of 84% silver). The La Cigarra silver deposit also contains appreciable amounts of lead, zinc and gold.
