IC Potash Achieves Positive Results from Counter-Current Leaching - Potassium Recovery Rates Improve to 97% from 91% and are Expected to Result in Lower Operating Costs

TORONTO, May 9 /CNW/ - IC Potash Corp. ("ICP" or the "Company") (TSXV: ICP) (OTCQX: ICPTF) announced today very positive results of metallurgical testing focused on increasing the recovery of potassium sulphate from the polyhalite resource of the Company's flagship Ochoa project in New Mexico.

Conducted by Hazen Laboratories, one of the world's premier metallurgical and processing laboratories, the tests obtained 99% recoveries when using counter-current leaching.  The Company estimates that leaching recoveries of at least 97% will be obtained in an operating plant environment. Initial test results as announced March 21, 2010 had obtained 91% recovery rates.

"Our latest test results are significant on a number of levels," said Mr. Randy Foote, Chief Operating Officer. "They clearly demonstrate that a high recovery of potassium can be obtained through counter-current leaching. Just as important, because the recovery rate is higher than we anticipated, we expect our operating costs will be lower as a result."

Counter-current leaching occurs when fresh ore is leached with previously produced potassium sulphate solution and previously leached rock a second time with new water.

Test Results:

More than 80 individual leaching tests were conducted. Parameters that were studied included dissolution of the calcined ore, dissolution of side products, identification and quantification of the side products, ore to water ratios, and the effects of salt (halite) on the dissolution process and evaporation processes.  It was determined that leaching water containing no more than 1 per cent salt should be used.

These tests confirm previous U.S. Bureau of Mines work regarding the leaching of polyhalite to solutions of sulphate of potash and magnesium sulphate. This data is now being used to design a full-scale counter current leaching system. Additional testing using larger scale equipment will be completed this summer.

About IC Potash Corp
IC Potash intends to become a primary producer of Sulphate of Potash ("SOP") by mining its 100%-owned potash Ochoa property in New Mexico. SOP is a non-chloride based potash fertilizer that sells at a substantial premium over the price of Muriate of Potash ("MOP"), the most widely used fertilizer in the world. Typically SOP sells at a premium of 50% to MOP. ICP is focused on being the lowest cost producer of SOP in the world. The SOP market is six million tonnes per year.  SOP is a significant fertilizer in the fruit, vegetable, tobacco, potato, and horticultural industries, and for agriculture in saline and dry soils and soils in which there is much agriculture with varieties of crops.  Much of the agricultural soil in China, India, and the United States is salty.  ICP's Ochoa property consists of over 100,000 acres of federal subsurface potassium prospecting permits and State of New Mexico Potassium mining leases.
