Overview

Western Potash Corp. (TSX:WPX) is a junior potash development company based in Vancouver, British Columbia. The company’s 100%-owned Milestone property is located approximately 30 kilometres Southeast of Regina, Saskatchewan, Canada. The Company is planning to build a solution mine at Milestone by 2015, with lower expected capital costs and a shorter timeline to production than conventional underground mining entails. Western potash now has the most advanced production programs amongst the last few potash juniors left in Saskatchewan. The Company is one of the last public junior potash pure plays with high-quality assets in Saskatchewan, with close proximity to some of the world’s largest potash mines and land holdings.

Investment Highlights

• The company has delineated a significant potash resource
• Macroeconomic indicators support increased fertilizer use in the future
• Excellent infrastructure, close to markets
• The milestone project is located adjacent to known potash producing properties
• The political risk is minimal due to its location in Canada
• The company has begun discussions with strategic partners
• Advanced engineering company involved in the feasibility process

Company Objectives

• Identify and purchase land for plant construction
• Choose the most appropriate water source option for the solution mine
• Arrange financing to build the mine
• Complete Pre-feasibility Study by August 2011
• Complete Feasibility process by late 2012
• Submit an environmental assessment study to the Government
• Begin mine construction by2013
• Begin potash production by 2015

Key Property

Milestone, Saskatchewan

The company’s flagship property, Milestone, is located 30 kilometers southeast of Regina, Saskatchewan, and about 50 kilometers from the world’s largest potash solution mine (Mosaic’s “Belle Plaine” Mine).

Size of Property

The Milestone property originally consisted of two mineral permits (KP408 and KP 409) encompassing a total of 157,400 acres (See map above).

The mineral permits have now progressed to a mining lease (KLSA 008) of which crown leases cover 85,262.5 acres and private mineral leases cover 27,057 acres, additional private mineral leases held outside the original permits add another 30,030 acres for a total lease area of 142,350 acres.

Mineral Resource

On April 26^th 2011, the Company announced an updated NI 43-101 compliant mineral resource estimate for its Milestone property totalling 244 million tonnes of measured and indicated potash resource. This resource estimate was prepared by Agapito Associates Inc. (“AAI”) of Grand Junction, Colorado, and increased the original Milestone resource by an average of 40%.

History

The company completed a two phase exploration program on the Milestone Property in 2009-10 and has now progressed to the feasibility and mine development stage.

Phase one consisted of 179 line kilometers of 2D seismic geophysics and purchased 284 line km of regional 2D seismic data. Additionally, four exploratory wells totaling 7,198 meters were completed, representing the first drilling completed on the permit. Phase one ended with the initial NI 43-101 resource calculation being delivered.

Phase two consisted of a 3D Seismic Survey as well as an additional five exploratory wells. Phase two ended with the delivery of an NI43-101 resource calculation totalling 174 million tones of measured and indicated resource.

An additional two wells were drilled to obtain information for the feasibility process resulting in the delivery of an updated NI43-101 resource calculation totaling 244 million tones of measured and indicated resource. The updated and expanded resource calculation will now be incorporated into the solution mining plan, part of the integrated feasibility process (“PFS + FS”) currently being completed by AMEC Americas Limited.

Current Program

AMEC has been engaged as the Lead Engineering Consultant for the Feasibility Study Process on the Company’s Milestone Potash Project.  This process begins with the commencement of a Prefeasibility Study (the “PFS”). The Company, AMEC, as well as, other consultants, will each contribute expertise to specific elements of the PFS. This includes all the facilities required for the development of a new potash solution mining operation. The PFS scope incorporates prefeasibility level engineering for all facets of the project required in order to reach the target plant capacity. The exact plant capacity for the feasibility study is not yet established, but, will be reflective of the most profitable throughput possible for a plant with two optimized trains of evaporation and crystallization. Both primary and secondary cavern production will be included in the solution mining methodology. The integrated Feasibility process remains on schedule and on budget, with an estimated “PFS” completion date sometime during the Third quarter 2011. The Feasibility Study (“FS”) has an expected completion date of the fourth quarter 2012.

In addition to the initial water source delivery option from Buffalo Pound Lake through the Saskatchewan Water shed authority; the company has signed a Memorandum of Understanding (“MoU”) with the City of Regina for a second potential water supply option for the Company’s Milestone Potash Project. As a result of this MoU, the Company will include new water supply options in its feasibility study process, which underscores the substantial environmental, as well as, economic benefits for both the Company and the City of Regina.

Golder Associates Ltd. of Saskatoon, Saskatchewan continues to assist the Company with environmental baseline studies and the preparation of an Environmental Impact Statement (“EIS”) for the Milestone project. This work remains on schedule and on budget, with an anticipated EIS submission date of Q3 2012.
