PR Newswire (Canada)
TORONTO, May 9 /CNW/ -- 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. All scientific and

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. NEITHER THE TSX
