Advancing A New Discovery
In The Parral Silver District, Mexico

International Northair Mines Ltd. (TSXV: INM) (the "Company" or "Northair") is pleased to announce that, in compliance with National Instrument ("NI") 43-101, it has filed on SEDAR the Technical Report for the maiden resource estimate, as released on February 26, 2013, for its La Cigarra silver project located in north central Mexico. The Technical Report titled "San Gregorio / Las Carolinas Resource Technical Report, La Cigarra, Chihauhua, Mexico" was completed by JDS Energy and Mining Inc. with the resource estimate by Arseneau Consulting Services ("ACS") and is available on the Company's website by clicking the following link:

Resource Estimate

The resource estimate contained in the Technical Report was calculated based on results from 143 of 154 holes totaling 25,576 metres drilled along the open ended La Cigarra mineralized system which has a drilled strike length of at least three (3) kilometres. The 143 holes included in this initial resource estimate were positioned within a potentially surface minable mineralized area comprised of the San Gregorio and Las Carolinas mineralized zones, which combined form a total strike length of 2.1 kilometres within the known three (3) kilometres. The mineral resource estimate was constrained by a Whittle™ pit shell at an economic cutoff grade of 30 g/t of silver and metallurgical recoveries of 84% silver. Highlights of the mineral resource estimate are as follows:

• Measured and Indicated mineral resources of 50,494,000 ounces of silver within 20,755,700 tonnes at an average grade of 76 g/t silver;
• Inferred mineral resource of 3,515,900 ounces silver within 1,780,000 tonnes at an average grade of 61 g/t silver;
• Higher than average grade zones outcrop, which could improve the assumed project economics in the early years;
• Significant by-products include 40,100 ounces of gold in the measured and indicated categories as well as appreciable lead and zinc values, as provided in mineral resource estimate tables noted below.

A summary of the mineral resource estimate contained in the resource shell as calculated by ACS at a 30 g/t silver cut-off grade and metallurgical recoveries of 84% silver is listed below:

Note:* Mineral resources are reported in relation to a conceptual pit shell at a 30 g/t silver cut-off. Mineral resources are not mineral reserves and do not have demonstrated economic viability. All figures are rounded to reflect the relative accuracy of the estimate. All composites have been capped where appropriate.

The mineral resources of the La Cigarra Project are sensitive to cut-off grade. To illustrate this, the block model quantities and grade estimates within the conceptual pit are presented in the following table at different cut-off grades.

Note: Figures presented in this table for cut-off values below 30 g/t silver should not be misconstrued with a Mineral Resource Statement. The figures are only presented to show the sensitivity of the block model estimates to the selection of cut-off grade.

The development of the comparative tables has relied on the work of experts as described in this release. The following factors should also be noted:

• Mineral resources were estimated in conformance with the CIM Mineral Resources definitions referred to in National Instrument 43-101, Standard of Disclosure for Mineral Properties;
• The resource estimate considered the results of 154 drill holes totaling (25,576 metres) and was calculated by using 143 of these holes;
• Mineral resources were estimated by ordinary kriging in 10x10x10 metre blocks. Grades were capped to 500 g/t silver in the high grade portion of the mineralization:
• Mineral resources were classified as Measured if at least three (3) drill holes were found within a 75 x 50 x 25 metre search radius. Blocks were classified as Indicated if two (2) drill holes were found within a 75x50x25 metre search radius and blocks were classified as Inferred if at least three (3) drill holes were found within a 100x75x30 metre search radius;
• The "reasonable prospects for economic extraction" requirement generally implies that the quantity and grade estimates meet certain economic thresholds and that the mineral resources are reported at an appropriate cut-off grade taking into account extraction scenarios and processing recoveries. In order to meet this requirement, ACS considers that major portions of La Cigarra mineralization are amenable for open pit extraction;
• In order to determine the quantities of material offering "reasonable prospects for economic extraction" by an open pit, ACS, with the assistance of JDS, used Whittl™ pit optimization software and reasonable mining assumptions to evaluate the proportions of the block model (Measured, Indicated and Inferred blocks) that could be "reasonably expected" to be mined from an open pit;
• The optimization parameters, found in the table below, were selected based on experience and benchmarking against similar projects. The reader is cautioned that the results from the pit optimization are used solely for the purpose of testing the "reasonable prospects for economic extraction" by an open pit and do not represent an attempt to estimate mineral reserves. There are no mineral reserves on the La Cigarra Project. The results are used as a guide to assist in the preparation of a mineral resource statement and to select an appropriate resource reporting cut-off grade.

Immediate Resource Expansion Potential

Immediate exploration potential at La Cigarra exists within and adjacent to the current resource area (between sections 6+00S in Las Carolinas and 3+50N in San Gregorio) at a 30 g/t silver cut-off as presented in the table below. The potential silver quantity and grade is conceptual in nature as there has been insufficient exploration to define a mineral resource and it is uncertain that further exploration will result in the target being delineated as a mineral resource. This exploration quantity and grade was determined based on a single drill hole within the 100m search ellipse.

Immediate Exploration Potential adjacent and within the San Gregorio/Las Carolinas Zones, La Cigarra Project

		Potential In-Situ Grade				Potential Contained Metal
Category	Tonnes (000)	Ag (g/t)	Au (g/t)	Pb (%)	Zn (%)	Ag (oz)
Exploration Potential	3,000 to 4,500	65 to 75	~0.06	0.09 to 0.1	0.13 to 0.14	6,000,000 to 10,000,000

The long section (shown below) covering the San Gregorio and Las Carolinas zones demonstrates the meaningful drill intersections that encountered mineralization below and adjacent to the optimized pit, which were not included in the calculation of the resource estimate.



Furthermore, considerable resource exploration potential exists along the open continuous six (6) kilometre long La Cigarra mineralized system. This potential is in part supported by soil sampling along trend of the system, comprising the La Borracha Zone to the north (where nine (9) drill holes have intercepted significant silver mineralization) and the Las Venadas Zone to the south (which has returned surface silver values of up to 233 g/t silver over 2.5 metres). The defined target zone at Las Venadas covers an area of approximately 230 metres by 90 metres.

In addition, numerous other target areas within the remaining 32,000 hectare land package could host significant mineralization as evidenced by a cluster of historic workings and mineralized grab samples obtained from preliminary prospecting.

About International Northair Mines Ltd.

Northair is a mineral exploration company engaged in the acquisition and development of gold and silver properties in Mexico. The Company is currently focused on advancing its La Cigarra silver project located in the state of Chihuahua, which hosts a robust NI 43-101 compliant silver resource estimate that also contains appreciable lead, zinc and gold values. Excellent exploration potential exists to the north of the deposit within the La Borracha Zone (where nine (9) drill holes have intercepted significant silver mineralization) and to the south where the extension of the La Cigarra structure has demonstrated a strong mineralized system with numerous drill targets. The permissive geology and attractive surface sampling results present a compelling opportunity to expand the known resource. The Company is presently prioritizing target areas for an expected 2013 drill program.
