Potash One Announces Sufficient Potash Reserves to Support Its Legacy Project for 47 Years

VANCOUVER, BRITISH COLUMBIA--(Marketwire - 10/18/10) - Potash One Inc. (the "Company" or "Potash One") (TSX:KCL - News) is pleased to announce that it has received a NI 43-101 Technical Report (the "Technical Report") upgrading the potash mineral resource to potash mineral reserves for the Company's Legacy Project located within the KP 289 permit area. The potash mineral reserve presented in the new technical report is based upon a 100 year mining plan prepared by Agapito Associates, Inc. and a 40 year comprehensive financial model prepared for the Legacy Project Feasibility Study by SNC Lavalin of Montreal, Quebec.The Technical Report upgrades previously reported indicated and measured resources to proven and probable reserves and recalculates indicated and inferred resources on the KP 289 permit area to the following new levels:

 

--------------------------------------------------------------
Recoverable Tonnes KCl
CATEGORY % KCl (Million Tonnes)
--------------------------------------------------------------
Proven Reserves 28.6 27.3
--------------------------------------------------------------
Probable Reserves 29.0 108.5
--------------------------------------------------------------
Total KCl Mineral Reserves 28.9% KCl 135.8 Million Tonnes KCl
--------------------------------------------------------------

--------------------------------------------------------------
Indicated Resource 27.1 80.1
--------------------------------------------------------------
Inferred Resource 26.9 859.4
--------------------------------------------------------------

The Potash Reserves and 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 23% KCl was used in the Esterhazy and Belle Plaine potash beds. A radius of influence from cored drill holes of 0.8 and 1.6 km were used for the Proven and Probable Reserves within the Mine Plan Area. A radius of influence from cored drill holes of 1.6 and 8 km were used for the Indicated and Inferred resource areas outside of the Mine Plan Area.The total proven and probable reserves of 135.8 Mt of KCl are sufficient to support mining at the annual rate of 2.86 Mt of KCl for 47 years. This reserve estimate is contained on the assigned crown lands (97,240-acres) and the leased freehold areas (3,680 acres) within the radius of influence of the six recently cored and assayed drill holes. When the exploration permit is converted to a mine lease area an additional 1,150 acres of land will become available from crown lands that were unassigned and within the exploration permit area and associated freehold lands that have mineral lease agreements in-place. The additional acreage has proven and probable reserves of KCl within 1.6 km of the cored drill holes of 24.5 million tonnes sufficient to extend the current mine life to 56 years.As commercial mining is initiated, the geological information from the ongoing well drilling for solution mining will be used to further define and expand the mineral reserves and the mineral resource. As the 859.4 million tonnes of Inferred Resource and the 80.1 million tonnes of Indicated Resource are further defined and reclassified, the KP-289 Permit area has the potential to support an ongoing mining operation well into the next century.The updated NI 43-101 technical report is a key step toward completing the Feasibility Study for the Legacy solution-mining project (the "FS"). The FS is being prepared by SNC Lavalin and is expected to be completed shortly.The updated potash reserve estimates, effective as of October 12, 2010, were prepared by Dr. Michael Hardy, P.E., and Dr. Doug Hambley, P.E. of Agapito Associates Inc., of Grand Junction, Colorado, and are based on the resource data presented in a earlier 2009 Technical Report authored by Hardy, Steve Halabura, P. Geo., and Debbie Shewfelt P. Geo. of North Rim Exploration Ltd., of Saskatoon, Saskatchewan. The reserve estimate was prepared in accordance with the requirements of NI 43-101 of the Canadian securities regulators. As required by NI 43-101, the Technical Report supporting the reserve estimate will be filed on SEDAR and be publicly available within 45 days following the date of this news release.This news release was reviewed by Dr. Michael Hardy P.E., of Agapito and Associates Inc. who is a Qualified Persons under NI 43-101 Rules and Policies and is the principal author of the Technical Report upon which this news release is based.ON BEHALF OF THE BOARD OF DIRECTORS,Paul F. Matysek, M.Sc., P.Geo., President and Chief Executive OfficerAbout Potash One Inc.:Potash One Inc. is a well-funded, TSX-listed Canadian resource company engaged in the exploration and development of advanced potash properties amenable to solution mining.
