WPX reports composite thickness of 24.4m of potash mineralization with a grade of 18.2% wt K2O on fourth well at Milestone, SK
Western Potash Corp. (the “Company”) (TSX.V: WPX, FSE: AHE) is pleased to announce that it has received the complete results from its first phase drill program on the Milestone property in southern Saskatchewan. Gamma ray results have been reported in previous news releases for the four wells drilled in the initial exploration phase and potash assay results for the first well were reported in a June 15th, 2009 company release. Highlighted in the fourth well is a 24.4 m composite intersection of potash mineralization with a weighted average grade of 18.2 wt % K2O across three potash members.
The 100% owned Milestone property, comprising 500 square kilometers, is located 30 kilometers southeast of Regina, and southeast of Mosaic’s Belle Plaine Mine, one of the largest producing potash solution mines in the world. The potash mineralization encountered within the Patience Lake and Belle Plaine potash members in this drill program is similar in grade and thickness to those reported at the operating Belle Plain mine.
The Milestone-003 well is the fourth well drilled on the Milestone property and is located approximately 12.5 km and 7.5 km to the southeast of the first and second well sites reported previously. A summary of the results from this well are presented in Table 1.

|Potash Member||From (KB, m)||To (KB, m)||Interval (m)||K2O Wt %||MgO Wt %||Insoluble Wt %||Best Intercept|
|Patience Lake||1715.55||1729.45||13.90||18.38||0.09||11.32||21.34 wt% K2O over 6.1m|
|Belle Plaine||1731.45||1736.3||4.85||18.37||0.09||3.78||20.11 wt% K2O over 3.6m|
|Esterhazy||1756.15||1761.75||5.60||17.75||1.57||3.96||30.17wt% K2O over 1.7m|
Note: Total intervals noted in this release are composites. All drill intercepts noted in this release are considered the true thickness of the mineralization; as the salt beds are relatively flat-lying and down-hole directional surveys indicate the hole was essentially vertical upon intersecting the salt and potash sequences. The core recovered from this hole was logged, photographed, split, and sampled at the Company’s secure core storage facility on the property. All samples were handled in accordance with the Company’s Chain of Custody procedures. The half-split core samples from the wells were analyzed at the Saskatchewan Research Council (SRC) Laboratory in Saskatoon. The Laboratory has been certified by the Standards Council of Canada (SCC) to conform to the requirements of ISO/IEC 17025:2005 (CAN-P-4E).
The Company is very pleased with the potash grades intersected in the Patience Lake and Belle Plaine potash members reported for the Milestone-003 well, as these are considered particularly exceptional. In addition, these potash hosting members have very low carnallite and low insoluble contents, which is also very encouraging as they are critical factors for developing a solution mine. The grades reported from the Esterhazy member are lower in comparison to grades reported from the same member in previous wells. Also, the carnallite content within the Esterhazy potash member is considered too high for effective economic extraction of potash in a solution recovery process.
