ICP IC Potash Corp.

TORONTO, March 21 /CNW/ -- TORONTO, March 21 /CNW/ - IC Potash Corp. ("ICP", or the "Company") (TSXV: ICP, OTCQX: ICPTF) announced today successful metallurgical testing results from Hazen Laboratories, Inc. ("Hazen"), one of the world's premier metallurgical and processing laboratories. These tests concluded liquor concentrations averaging 10.4 grams of Sulphate of Potash ("SOP") per 100 grams of water, with recovery rates of up to 91 percent SOP can be produced. The Hazen leaching procedures produced Sulphate of Potash concentrations consistent with previous work carried out by the United States Bureau of Mines during the 1930's and pilot studies by Potash Corporation of America during the 1950's. The prior testing is described in the Canadian National Instrument 43-101 compliant Preliminary Economic Assessment Technical Report entitled "NI 43-101 Technical Report on the Polyhalite Resources and Updated Preliminary Economic Assessment of the Ochoa Project". This report was filed on January 17, 2011 and can be viewed at www.sedar.com. The next phases of testing at Hazen will establish further data required to select and size the equipment for each processing step, including grinding, calcination, leaching, centrifugation, and filtration.  Randy Foote, Chief Operating Officer stated "These results are very encouraging as they confirm the work done by the Bureau of Mines, which forms the basis of our processes. These recent findings also closely match earlier results on the first metallurgical tests performed. This indicates that the processes are simple, predictable, and robust." Test Results:   1. Minus 10 mesh polyhalite was heated to complete calcination at 480 degrees Centigrade for 15 minutes. Calcination is the procedure established by the USBM for making polyhalite easily leachable. Leaching was used by Potash Corporation of America in their pilot testing. 2. Using 2 per cent salt leaching solution, liquor concentrations averaging 10.4 grams of SOP per 100 grams of water were obtained, with 91 per cent recovery of SOP. This is consistent with the USBM work where concentrations of 10.0 to 10.4 grams of SOP per 100 grams of water were obtained with recovery ranging from 92 per cent to 95 per cent. 3. Using pure water for leaching, liquor concentrations averaging 8.8 grams of SOP per 100 grams of water were obtained, with 77 per cent recovery of SOP. This is also consistent with USBM work where 8.5 grams to 8.8 grams of SOP per 100 grams of water were obtained with recoveries ranging from 77 per cent to 80 per cent. 4. Typically higher brine concentrations produce lower recoveries with or without the presence of salt. This confirms the USBM work. Sidney Himmel, President and Chief Executive Officer of ICP, stated "It is our expectation that further detailed testing will continue to confirm historical work. These independent results are in line with management expectations, and represent a major milestone for our company."

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.
