VANCOUVER--(Business Wire)--
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.

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.

This news release contains Forward Looking Statements regarding our intentions
and plans. Forward looking statements in this news release include that results
from this well confirm very little or no carnallite is evident in any of the
three potash members, within a large area that surrounds five of the wells in
the resource definition area; that the absence of carnallite in the Esterhazy
member in this area is regarded as highly encouraging for management, as
additional resources will surely be brought into the resource calculation models
with the addition of the third potash bed, which was not included in the initial
resource calculation; that the presence, thicknesses and grade of the potash
beds in these 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: that the company feels 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; that the Company is currently compiling
this information to update the NI 43-101 resource calculation; that Boyd
PetroSearch with expertise on potash projects was contracted to complete the
interpretation of the 3D seismic survey; that the 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; that 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; that the data will be incorporated into
an updated resource estimate compliant with NI 43-101 standards; that initial
seismic interpretations are expected to be available within two to three weeks;
that 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 and report; that the report on the updated resource is expected to
be completed during the second quarter of 2010 subsequent to the delivery of the
seismic interpretation report from Boyd PetroSearch. It is the Company`s policy
not to update forward looking statements. Various factors may prevent or delay
our plans, including but not limited to, contractor availability and
performance, weather, access, mineral prices and success and failure of the
exploration and development carried out at various stages of the program.
Readers should review risk factors applicable to junior mining exploration
companies generally to understand the variety of risks that can affect the
Company.
