Mistango River Resources Drills 94m of 0.946 g/t Gold at Omega;

Company Adds Market Liquidity Program through CHF Investor Relations

Kirkland Lake, Ontario, April 30, 2012: Mistango River Resources Inc. (?Mistango? or the ?Company?) (MIS: CNSX) (GLRAF: OTC) today announced more Diamond drill results from ten holes from this year?s drilling at its 100%-owned Omega Gold Project, located in the Kirkland Lake mining district of Ontario on the Cadillac fault system.

Drill Intercept Highlights:

• OM-12-76:  0.946 g/t gold over 94 metres (including 18 metres of 1.360 g/t gold)
• OM-12-72:  1.177 g/t gold over 59 metres (including 34 metres of 1.834 g/t gold)
• OM-12-70:  0.997 g/t gold over 54 metres (including 10 metres of 2.421 g/t gold)

?The wide widths of gold mineralization we?ve intersected this year in the potential open pit area are very encouraging since they are certain to add resources there to the deposit?s geological model. We have now completed 90 holes and the last eleven holes all are in the potential open pit area. Once those assays have been received we will proceed to a 43-101 resource estimate,? commented Robert Kasner, President and CEO of Mistango.

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

Regarding the recently announced joint venture agreement between Bear Lake Gold Ltd. (TSXV: BLG) and Gold Fields Limited (NYSE: GFI), one of the world?s largest gold producers, CEO Kasner added, ?Of course we?re thrilled to see the attention that this major gold mining company has taken in the property that curves around the historic Omega mine site area on three sides. We are not surprised that the Cadillac/Larder Lake fault system would be singled out by them; their nearby presence adds confidence, another level of credibility really, to what we?re seeing at Omega.?

Assays are pending for the remaining eleven holes in the 2012 Omega Gold Project?s drill program.
