Potash One Significantly Increases Potash Resources at Legacy Solution-Mining Project in Saskatchewan, Canada

Potash One Inc. (the "Company" or "Potash One") (TSX: KCL) announced today that it has significantly increased the potash resource estimate on the Company's Legacy Project - a planned solution mine in Saskatchewan, Canada, based on an updated technical report prepared pursuant to NI 43-101.

The report expands and upgrades the estimated resources on the 97,240-acre project to the following new levels:
- 29 million tonnes of Measured potash resource;
- 222 million tonnes of Indicated potash resource; and
- 852 million tonnes of Inferred potash resource.

Paul F. Matysek, President and Chief Executive Officer of Potash One, said that the results are a major advance for the Company.

"The updated Measured and Indicated resource estimate provides a sufficient potash resource foundation for a pre-feasibility study based on a projected production rate of 2.5 million tonnes per year. Subject to financing and a successful feasibility study, the Legacy Project could enter the potash marketplace as early as late 2013 and be the world's first greenfield potash mine since 1987."

The following table (Table 1) summarizes the updated resource estimate on the Legacy Project:

The Potash Resource is the estimated metric tonnes of refined potash product, taking into account the recovery by solution mining and processing losses (i.e. extraction factor, cavern recovery factor, geological anomaly factor, and processing losses). A cutoff grade of 15.8% KCl and a radius of influence from cored drill holes of 0.8, 1.6 and 8 km were used for the Measured, Indicated and Inferred areas respectively.

During the Resource Confirmation drilling program, Potash One drilled six holes totaling more than 9,000 metres. The Company also carried out approximately 271 linear kilometres of 2D seismic and approximately 73 square kilometres of 3D seismic surveys. The 2008-2009 Potash One drilling program and 3D seismic survey focused exclusively on the southern area of the KP-289 lease. The southern target area has the potential for expansion to the west, north, and east.

The updated resource estimate adds 29 million tonnes of Measured potash resource, 157 million tonnes of Indicated potash resource (a 242% increase) and 230 million tonnes of Inferred potash resource (a 37% increase) to the January 24, 2008, estimate.

The updated potash resource estimate is effective May 12, 2009, and was prepared by Dr. Michael Hardy, P.E., of Agapito Associates Inc., of Grand Junction, Colorado, and Steve Halabura, P. Geo., of North Rim Exploration Ltd., of Saskatoon, Saskatchewan. The resource estimate was prepared in accordance with the requirements of NI 43-101 of the Canadian securities regulators. As required by NI 43-101, a technical report supporting the resource estimate will be filed on SEDAR and be publicly available within 45 days following the date of this news release.

The updated NI 43-101 technical report is a key step toward completing the pre-feasibility study (PFS) for the Legacy solution-mining project. The PFS is being prepared by SNC Lavalin of Montreal, Quebec, and is expected to be completed early next month. In addition to the 2.5 million tonnes per annum study, SNC Lavalin is preparing a cost estimate addendum based on 800,000 tonnes per annum, which is targeted for completion in July this year. Note that mineral resources are not mineral reserves and do not have demonstrated economic viability.

The Technical Report being prepared by Agapito Associates et al. will include a summary of results of the Resource Confirmation programs conducted in 2008 and early 2009 (see Table 2), in addition to the original information contained in the January 24, 2008, NI 43-101 Technical Report Concerning Subsurface Mineral Permit KP 289, Findlater Area, Saskatchewan, prepared by the same authors.

A Mineral Resource is an inventory of mineralization that under realistically assumed and justifiable technical and economic conditions might become economically extractable; however, at this time the Mineral Resources do not have demonstrated economic viability. At this time, no part of the Mineral/Potash Resource can be claimed as a Mineral Reserve because a Preliminary Feasibility Study has not been completed. As noted above, a Preliminary Feasibility Study is in progress and will be released in June 2009. At that time, a further NI 43-101-compliant estimate of Mineral Reserves will be released.

Both individuals are Qualified Persons under NI 43-101 Rules and Policies and are the authors of the updated NI 43-101 Technical Report on which this news release is based.
