Western Potash Corp. Executes Crown Subsurface Mineral Lease, Files Scoping Study Executive Summary

WESTERN POTASH CORP., (the 'Company?) (TSX Venture: WPX) is pleased to
announce that the Province of Saskatchewan has granted the Company a
subsurface mineral lease on its 100% owned Milestone property in
southern Saskatchewan. The lease was granted by Special Agreement under
Section 4(b) of The Crown Minerals Act, and contains more than 87, 500
acres of Crown held mineral leases. The renewable, twenty one year lease
was granted by Ministerial order and provides the Company with the full
and exclusive power and right to mine Crown owned subsurface minerals,
including potash, contained within the lease area, subject to the
provisions outlined by The Saskatchewan Subsurface Mineral Regulations,
1960. The granting of this lease is one of the key steps towards the
development of the Milestone Potash Project.

The Company is also pleased to announce that further to its news release
dated September 20, 2010, it has filed today with the Canadian
securities regulators, a summary (the 'Summary') of the work and results
of the Milestone Potash Project Scoping Study (the 'Study?) dated
September 2010. The Study was prepared exclusively for Western Potash by
AMEC Americas Limited ('AMEC?). The Study was based on, and supported by
the, 'NI 43-101 Technical KP 408 and KP 409, Saskatchewan?, dated July
12, 2010, and filed on SEDAR on July 16, 2010 (the 'Report?) prepared by
Agapito Associates Inc. and was reported in the Company′s news release
dated June 3, 2010. The Summary was compiled by Western Potash Corp.,
and will be available on SEDAR at www.sedar.com
on November 2, 2010 and also on the Company's website at www.westernpotash.com.

This Study confirmed that the Milestone resource shows significant
positive economics and that the asset is of sufficient size and grade to
support solution mining for more than forty years at a production rate
of 2.5Mt/yr.

Highlights of the Study include:

• 
  High formation temperatures at Milestone (60 to 65⁰C)
  reduce operating costs by 8.5% when compared with other solution
  mining projects in Saskatchewan that access lower (50 to 55⁰C)
  formation temperatures.
  
• 
  Long Term Potash Gate Price: The CRU Group provided yearly potash
  price estimates for the 2015 to 2025 period. The resulting average
  price of $US 511/t was then assumed for the 2025 to 2055 period.
  
• 
  Other assumptions: Assumes a flat US$ exchange rate. Construction is
  assumed to take place over a two year period, production beginning in
  project year three. CAPEX based on 100% equity. Tax and royalties were
  calculated using a flat rate of CAD$28.90/t.
  
• 
  Since the analysis is based on a cash flow estimate, it should be
  expected that actual financial results may vary from these
  predictions. An accuracy assessment of the cost estimates was
  completed as part of this study and is estimated to be  ±35%.
  

The Study recommends immediate commencement of a Pre-Feasibility study
based on the attractive economic assessment presented.

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.

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.
