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 . 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:



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.






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.






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.






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."

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.
