*REVISED* EPM Mining Ventures Inc. Announces Initial Resource Estimate of 29.5 Million Tonnes of K2SO4 Equivalent (Measured + Indicated) at Sevier Dry Lake Property

/NOT FOR RELEASE OR DISTRIBTUION IN THE UNITED STATES OR FOR DISSEMINATION TO U.S. NEWS WIRE SERVICES./

TORONTO, May 22, 2012 /CNW/ - EPM Mining Ventures Inc. (TSXV: EPK) ("EPM" or the "Company") is pleased to announce the receipt of a National Instrument 43-101 ("NI 43-101") Mineral Resource Estimate (the "Estimate") for its Sevier Lake property in Utah. The Estimate was prepared by Norwest Corporation ("Norwest") and is effective as of May 1, 2012. The Estimate indicates that the in-situ brines in the Sevier Lake contain the mineral equivalent of approximately 29.5 million tonnes of measured plus indicated potash resource, and approximately 9 million tonnes of inferred potash resource; all as K₂SO₄ equivalent.

Lance D'Ambrosio, Chief Executive Officer of EPM, said; "We are very pleased with the results of this estimate, which demonstrate that we have an extensive potash deposit. We are very gratified with these findings and look forward to taking the next steps towards building our sulfate of potash project."

A total of 414 holes were drilled on the Sevier Lake property using a variety of drilling methods. The following brine resource parameters were acquired from drill hole sampling of brine and host sediments:

• Gravimetric moisture content in weight percent
• Specific Gravity of brine and solid host sediments
• Cation in mg/l brine for Mg²⁺, Na⁺, and K⁺
• Anion in mg/l brine for Cl^- and SO₄^2-

The geometry of the brine aquifer was determined from the correlations of drill hole lithogic descriptions, penetrometer results, and moisture content measurements. The estimations of moisture content and brine grade (cations and anions) and specific gravity inputs into the 3D block model were influenced by the results of geostatistical analyses of the source drill-hole sample data. The estimated brine resource and associated major dissolved cations and anions for the brine aquifer are listed in a table below. Given that sufficient sulfate is present in the brine to utilize all potassium ions, the mineral equivalent tonnages of K₂SO₄ and other salt compounds that could be created using the available cations and anions in the brine resource are listed below as well.

A summary of the in-situ brine Mineral Resource and major dissolved cations and anions within the Sevier Lake is presented in the table below:

Peak Minerals Inc ("Peak"), an indirect wholly-owned subsidiary of EPM, owns a 100% leasehold interest in federal potassium leases comprising about 95,802 acres. The leases grant full rights of access and rights to utilize the surface for leasehold mining activities. The term of the leases is 20 years from the date of issuance, April 5, 2011, and for so long thereafter as Peak complies with certain rental, minimum royalty, and minimum annual production requirements, as well as other terms and conditions of the leases.

The same lease terms described above apply to the approximately 22,010 acres of federal potassium leases in which record title is held by LUMA Resources Inc. ("LUMA"). Peak will have development and operational control of these leases under the terms of its Cooperative Development Agreement dated July 15, 2011.

The 6,409 acres of State of Utah SITLA potash leases owned 100% by Emerald Peak Minerals, LLC ("Emerald Peak") grant full rights of access and rights to use the surface and subsurface for uses "reasonably incident to the mining of leased substances". Peak Minerals owns 40% of the membership interest in Emerald Peak and also has the contractual commitment from Emerald Peak to enter into a Unit Agreement or similar agreement and a Unit Operating Agreement that will be entered into by Peak, LUMA, and Emerald Peak. It is anticipated that these agreements will name Peak as Unit Operator and give Peak the sole right to develop and operate the SITLA Leases along with the Federal Leases.
