The Northair GroupINMNews Releases
Drill Program to Begin at Sierra Rosario

International Northair Mines Ltd. (TSXV:INM) has been informed that Sparton Resources Inc. (TSX-V, SRI) has signed a drill contract with Energold International Drilling Services for a minimum 1000 metre drill program to begin testing high priority targets at the Company’s wholly owned Sierra Rosario precious metal project in northern Sinaloa State, Mexico. The drilling equipment is currently being mobilized to the property and operations are expected to start in the third week of April. Sparton is earning an interest in the approximately 1100 hectare Sierra Rosario property from the Company and has previously completed an extensive geological, geochemical and geophysical work program which identified several excellent high grade silver-gold and base metal targets for drill testing. The La Josca and San Rafael zones represent the highest priority mineralized features located so far on the concessions.

La Josca Zone

Due to logistical constraints and the availability of drilling water supply at this time of the year the initial drill program will focus on the La Josca Zone located in the south central part of the property. Sparton’s 2005 field program traced the La Josca shear zone for approximately 1100 metres with coincident soil, rock chip and geophysical (VLF and magnetic) targets which are anomalous in silver, gold, and base metals values (see news release dated November 9, 2005). The gossaneous shear structure occurs in lower series volcanic rocks, varies from 8 to 30 metres in width, and is only partially exposed along this strike length. There are two short underground tunnels from historic mining activities accessing parts of the zone in the east-central part of the structure.

Mineralization sampled at La Josca returned values of up to 105g/t gold, 1.8% copper and 148g/t silver over true widths of 20cm to 7 metres. Six holes are planned in the initial program to test the La Josca Zone along a strike length of approximately 600 metres. Additional drilling will be dependent on the results of the initial program.

San Rafael Zone

The San Rafael Zone, located in the northern part of the property will be tested later this year when a local water supply is available for drilling. Access to the target area will be upgraded during the current drill program. Mineralization at San Rafael occurs in several styles including skarn contact mineralization and structurally controlled vein systems associated with a rhyolite body intruded into limestones and tuffaceous rocks of the upper volcanic series. The exposed alteration area near the intrusive has dimensions of approximately 250 metres by 120 metres, but the magnetic anomaly associated with the mineralized area and intrusive body is over 400 metres by 200 metres in size. A mine dump near the old workings averaged 146 g/t silver, 0.71 g/t gold and 0. 2% copper from a total of 105 samples taken by Sparton in the 2005 work program.

Results of the current drilling program will be reported when available.

Sparton can earn a 51% interest in the property by paying Northair $130,000 (Cdn.) in cash, issuing 275,000 common shares and incurring $800,000 (Cdn.) in exploration expenditures over a four year period.

Sparton’s exploration program in Mexico is being carried out under the direct supervision of A. Lee Barker, P.Eng., P. Geol., the Company’s President and CEO who is a Qualified Person under National Instrument 43-101. Analyses were done by ALF Chemex’s Laboratories in Hermosillo, Mexico using Induced Coupled Plasma (ICP) techniques for a 34 element group, and Atomic Absorption (AA) methods for gold and silver. AA/Gravimetric Finish method was used for higher grade samples.
