Enertopia Acquires Mildred Peak, Arizona Property

Vancouver, BC—Enertopia Corporation (ENRT-OTCBB) (TOP-CNSX) (the "Company" or "Enertopia") announces the definitive agreement for the Mildred Peak, Arizona project has been completed.

The Mildred Peak property is located approximately 65 miles south west of Tucson, Arizona. The property covers approximately 6,220 acres. Historic work on the project has included surface sampling, trenching and drilling of both high grade gold / silver targets and lower grade bulk tonnage potential gold / silver targets. The Property was drilled by Golden Arch Resources in 2004 and 2006. Below are summary results from three diamond drill holes from one area which appears to be open in all directions:

(Note: the historic drilling results have not been verified and the true thickness of the zone is not known.)

Surface rock chip and trench sampling by Golden Arch Resources between 2003 and 2005 from three separate zones in the project area has returned values of copper, silver and trace gold as summarized below:

Note: The historic rock chip samples in Area A were taken from the area south east from Mildred Peak in rolling topography along with the 60 meters of trenching. Rock chip samples from Area B were taken from the western project area covering 500 meters by 250 meters. The historic surface trenching of 180 meters was taken inside a larger area of 300 meters’ x 500 meters and is along a hill slope in the property’s south western quadrant. The trench sampling was confirmed by Enertopia personal during a May 2011 site visit and the sampling results released by Enertopia on August 12, 2011 have confirmed the historic sample numbers.

Area B and C are separated by a distance of 1,000 meters running NE to SW and Area A is 800 meters to the ENE of Area B.

Historic work at Mildred Peak goes back to the late 1800’s. The property has multiple historic exploration pits where high grade gold and silver were mined in the past. The Jupiter and Gold Bullion mines at the northern end of the project area were the two main producing mines with limited production of high grade gold-silver material. Past work had focused on sourcing additional high grade deposits.

Enertopia believes there are near term opportunities to potentially identify ounces in the ground from several large areas of near-surface, bulk tonnage style mineralization. Mineralization varies from the north east areas where gold, copper and silver is associated with pervasive siliceous alteration in felsic conglomerates and argillites to the south west areas where mineralization is mainly copper associated with iron and manganese oxides in argillites and felsic volcanics.

The terms of the agreement are as follows: Enertopia has previously paid $15,000 and is obligated to make $866,000 in additional cash payments staged over 5 years. Enertopia will also issue 1,000,000 common shares in payments over a 4-year period. In return, Enertopia will acquire a 100% interest in the Mildred Peak property, subject only to a 2.5% Net Smelter Returns Royalty.

“We are excited about signing the definitive agreement on Mildred Peak. Our due diligence has confirmed multiple targets for the discovery of potentially significant gold, copper, and silver mineralization,” said Robert McAllister, President. “We will initially focus on the potential for bulk tonnage mineralization by following up the historical surface sampling an initiating a comprehensive drill program.”
