WPX Intersects 19.9% K20 over 22.25m with little or no carnallite, providing an update on expanded resource definition drilling and seismic program

Western Potash Corp. (the “Company”) (TSX.V: WPX, FSE: AHE) is pleased to provide results from the first two wells completed as part of the expanded 5 well, $8.5 million CAD resource definition program on the Milestone property in southern Saskatchewan. These wells are the fifth and sixth wells drilled on the property. Results from the Milestone-004 well returned a 23.35 m composite intersection of potash mineralization with a weighted average grade of 17.35 wt % K2O across three potash members, while the Milestone-005 well reported a 22.25 m composite intersection of potash mineralization with a weighted average grade of 19.89 wt % K2O across three potash members. Results from the Milestone-005 well are considered of particular interest as very little Carnallite was intersected in any of the three potash members, including the Esterhazy member. The presence of Carnallite in the Esterhazy member is not unusual in the region, but the absence of Carnallite in the Milestone-005 well does suggest that in some areas of the Milestone property parts of the Esterhazy member could be of economic interest.

The Milestone-004 and Milestone-005 wells, as shown in figure 1 are located approximately 3.0 km to the south and north respectively of the Milestone-003 well which reported a composite thickness of 24.4m of potash mineralization with a grade of 18.2% wt K2O in a press release dated August 24, 2009.  A summary of the results from the two most recent wells are presented in Table 1.

Anmerkung: 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. Alle Proben wurden gemäß der Aufbewahrungsmaßnahmen des Unternehmens gehandhabt. Die halbierten Bohrkerne wurden im Saskatchewan Research Council (SRC) Laboratory in Saskatoon analysiert. Das Labor wurde durch Standards Council of Canada (SCC) zertifiziert, um der Norm ISO/IEC 17025:2005 (CAN-P-4E) zu entsprechen.

The Company points out that the presence, thicknesses and grade of the potash beds in these fifth and sixth wells are similar in tenor and are as encouraging as those seen in previous wells and indicate a remarkable continuity of the potash beds in the region when comparing with the results reported for the first four wells. The Company feels that the thicknesses and grades obtained by geochemical sampling and down hole gamma ray logging are consistent with those mined at the Belle Plaine solution mine and that it has now demonstrated regional continuity of all three potash members, over 18 km of strike length, between the wells drilled to date.

It is also very important to note that information from the drilling to date confirms the presence of the heat anomaly that helped attract the Company to the project area. Temperature measurements from all the wells show minimum formation temperatures ranging from 60° C to 65,5° C. Temperature will be an important component of the economics of future mining on the property. The solubility of potash increases with temperature such that the higher the formation temperature, the higher the yield of potassium chloride in the brine solution to be processed for potash recovery. A solution mine, accessing a higher formation temperature resource, will produce more potassium chloride in solution than an operation tapping an equivalent resource at lower formation temperatures. The Company views formation temperature as a key parameter in solution mining economics, offering advantages in solution mass-balance and savings in capital, energy and processing costs.

Die ca. 500 km² große Milestone-Liegenschaft, die sich zu 100 % im Unternehmensbesitz befindet, liegt ca. 30 km südöstlich der Provinzhauptstadt Regina und südöstlich der Mine Belle Plaine der Mosaic Company. Diese Mine ist einer der größten produzierenden Solungs-Kalibergbaubetriebe der Welt.

Seismic Update and Resource Calculation

The Company is also pleased to announce that the 2D seismic program has now been completed. This seismic program was designed to assist with planning the expanded drilling and the upcoming 3D seismic program. This work has allowed the Company to plan three additional wells, with drilling commencing immediately. Permitting and licensing of the Company’s 3D seismic program is now well underway.

Agapito and Associates Inc. of Golden, Colorado continues to draft an NI43-101 compliant inferred resource calculation and report based on the results of the initial four well drill program. This report is expected to be completed during the fourth quarter of 2009. Agapito and Associates has also been engaged to complete an NI-43-101 compliant indicated and inferred resource calculation based on the results of the expanded 5 well resource definition drill program, 2D seismic, and 3D seismic surveys. This report is expected to be complete during early 2010, subject to the completion of the aforementioned drilling and seismic surveys.
