西钾公司截获高达21.07% 品位K2O无光卤石钾盐矿床

Vancouver, April 22, 2010 - Western Potash Corp. (the “Company”) (TSX.V: WPX, FSE: AHE) is pleased to announce that it has received results from the final well completed as part of the expanded 5 well, $8.5 million CAD resource definition drill program on the Milestone property in southern Saskatchewan.  The Milestone-006 well reported a 16.65 m composite intersection of potash mineralization with a weighted average grade of 21.07 wt % K2O across three potash members.  A summary of the results from this well is presented in Table 1. Results from this well were delayed as the samples were submitted for engineering tests prior to being submitted for geochemical analysis.

Well 1 Potash Member From (KB,m) To (KB,m) Interval(m) K20 Wt% Mg0 Wt% Insoluble Wt%
Milestone-006 Patience Lake 1707.85 1714.1 6.25 20.9 0.1 12.43
  Belle Plaine 1717 1721.6 4.6 17.23 0.08 3.83
  Esterhazy 1739.35 1745.15 5.8 24.29 0.08 3.74
  Total     16.65 21.07 0.09 7.03

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).

Results from this well confirm that very little or no carnallite is evident in any of the three potash members. Management regards the absence of carnallite in the Esterhazy member in this area as highly encouraging, as additional resources will be brought into the resource calculation models which were not included in the initial resource calculation.

The Company wants to emphasize that the presence, thicknesses and grade of the potash beds in this well is similar in tenor and as encouraging as those seen in the previously reported eight wells.  This indicates a remarkable continuity of the potash beds in the region. 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.

The objective of this resource definition drill program is to define the grade, thickness, and extent of the higher grade potash zone around well 003, which reported a composite thickness of 24.4m of potash mineralization with a grade of 18.2% wt K2O within the Patience Lake, Belle Plaine and Esterhazy members.  The Company is currently compiling this information to update the NI 43-101 resource calculation that was announced on February 2, 2010.  The initial resource estimate consists of 32 million tonnes of indicated potash resource, as well as, 230 million tonnes of inferred potash resource (contained KCl).

The Company is also pleased to announce that the three dimensional (3D) seismic program designed to aid in upgrading the initial resource estimate reported in its February 2, 2010 news release, has now been completed.  Boyd PetroSearch of Calgary, Alberta, a global geophysical consulting firm providing an integrated approach to managing geophysical projects around the world, with expertise on potash projects was contracted to complete this survey.  Three dimensional (3D) seismic surveys are highly effective subsurface analytical tools, aiding in the identification and estimation of the extent of salt loss, solution-collapse anomalies, void-space mapping and other subsurface geological conditions.  The 3D seismic data provides a more detailed representation of the subsurface stratigraphy between drill holes on the property, and allows for a larger radius of influence to be used when estimating mineral resources.  The survey covered a total area of over 98 km2 and consisted of 410 km of source lines and 405 km of receiver lines.  Boyd PetroSearch will now oversee the data processing and interpret this seismic data.  The initial seismic interpretations are expected to be available within two to three weeks.

Agapito Associates Inc. of Golden, Colorado has now been provided with the well data and will continue to prepare and update an NI43-101 compliant resource calculation. The report based on the results of the nine well drill program, as well as, the 2D and 3D interpreted seismic survey data is expected to be completed during the second quarter of 2010.
Western Potash Corp. is a mineral exploration company engaged in the evaluation, exploration and development of potash mineral properties in Western Canada. The Company intends to define and develop a world-class potash deposit in an ecologically sustainable, economically efficient and socially responsible manner.
