Creso Announces Acquisition of Past Producing Mann Silver Mine, Milner Township, Ontario

MONTREAL, QUEBEC--(Marketwire - Sept. 1, 2011) - Creso Exploration Inc. ("Creso" or the "Corporation") (TSX VENTURE:CXT) (OTCQX:CRXEF) (FRANKFURT:C3X) is pleased to announce the acquisition of an option to purchase the Mann silver mine located in Milner Township. The property produced 178,000 ounces of silver from some 8,000 tons of ore for an average grade of over 21 ounces per ton (720.3 grams per tonne) of silver. The property has five shafts, the deepest of which (No. 3) is 200 vertical feet.

A ramp was also driven to the 210-foot level (from Report by L.J. Cunningham, Manridge Explorations Limited, February 11, 1985). The Corporation's objective at the Mann mine will be to confirm targets in the D-zone, which was partially mined and had intersections of up to 506 ounces per ton (17,356 grams per tonne) of silver over 9 feet, as well as 495 ounces per ton (16,978 grams per tonne) of silver over 7 feet, and numerous other veins reported.

The Corporation cannot yet confirm the grades and thicknesses reported in the historic literature. The Mann property is contiguous to the Corporation's claims in the Milner Township.

From 1968 to 1970, 8,096 tons of ore were treated at the Mann mine with an average grade of 21.5 ounces (609 grams) of silver per ton. From 1983 to 1984 1,000 tons of ore were processed from the ramp and produced approximately 30,000 ounces of silver. Operations ceased on December 1984. The Mann property is located "in the Gowganda Region of the famous Temiskaming Silver Area, from which 570,000,000 ounces of silver have been produced, including 60,000,000 ounces produced in the Gowganda Region. All of the silver production shows a close spatial and genetic relationship to the Nipissing diabase, which has intruded older rocks from a number of points to form a series of arches, basins and irregular forms. In the Gowganda Region over 95% of the silver produced has been obtained from the Nipissing diabase within basin structures. Elsewhere in the Temiskaming Silver area, much of the silver produced has been derived from intruded rocks".¹

The Purchase Option Agreement provides for the payment by the Corporation of $50,000 cash and the issuance of 500,000 common shares of the Corporation and a further payment of $50,000 cash and issuance of an additional 500,000 common shares six months later.
