Mistango River Resumes Drilling at Omega Mine Project

Kirkland Lake, Ontario, June 26, 2012: Mistango River Resources Inc. (“Mistango” or the “Company”) (MIS: CNSX) (GLRAF: OTC) today announced it has completed its $2.5 million private placement with Queenston Mining Inc. (TSX: QMI); the Company has resumed drilling at its 100% owned Omega Mine Property located at Larder Lake, Ontario. Drilling has begun with one drill while a second drill is expected to arrive within a couple of weeks. The present drill program consists of 24 holes, approximately 11,515 metres, designed to complete the recommended infilling drilling around the potential open pit area so that a NI 43-101 resource estimate can proceed as well as the drilling of the down-plunge extensions of the Omega deposit and the Lake zone.

“The confidence in our Company, and the Omega project in particular, that Queenston Mining has demonstrated through its share investments is highly encouraging for us. The support Queenston has shown, and their willingness to offer their expertise as we develop a potentially commercial ore body at Omega, I believe, is a strategic advantage Mistango has over other area projects,” commented Robert J. Kasner, President and CEO of Mistango.

Exploration drilling will take place on the Lake Zone and geophysical surveys on the South West Zone. For more information on these two sites please see the news release of March2, 2012.

Earlier results from 2012 drilling that continued the 2011 campaign were reported in a news release on March 2 and April 30, 2012.

Some exploration will also be carried out on Mistango’s 100% owned Sackville property located west of Thunder Bay, Ontario which will comprise mostly stripping of previously outlined IP (induced polarization) conductors and till sampling sites that returned high values in zinc and gold.

The Sackville Property is a contiguous assembly of eight non-patented claims and one patented claim close to power and rail totaling 3,944 hectares and is easily accessed by all-weather roads. Mistango has been working the property for over 10 years with a combination of drilling programs, geophysical surveys and detailed till and soil sampling to try and locate the high grade Stares (Stares Boulder 12% Zn, 0.6 % Cu, 4.4% Pb, 359 g/t Ag and 5.52 g/t Au) and Calvert boulders (Calvert Boulder 12% Zn, 0.26% Cu, 1.70% Pb 214.3 g/t Ag, 3.51 and g/t Au) found on the property and just to the south of the property.

Fred Sharpley, P.Geo., is the Qualified Person, as defined by NI 43-101, for the Omega and Stares Properties and he has reviewed and approved the technical information presented in this news release.
