VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 26, 2013) - Passport Potash Inc. (News - Market indicators)(OTCQX:PPRTF) ("Passport" or the "Company") is pleased to announce that it has received an updated independent CSA National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") mineral resource estimate for its Holbrook Basin property in Northern Arizona. The report, which also includes mineral resources from the Hopi properties, was completed by ERCOSPLAN IngenieurgesellschaftGeotechnik und BergbaumbH ("ERCOSPLAN"), a consulting and engineering firm, specialized in the potash and salt industry, headquartered in Erfurt, Germany. The resource was calculated by Dr Henry Rauche and Dr Sebastiaan van der Klauw members of the European Federation of Geologists.

The mineral resource estimate of the combined properties includes measured and indicated mineral resources totaling 397.94 million tonnes of mineralized material with an average grade of 14.65% (equivalent to 58.35 million tonnes of KCl). For the indicated category of the combined properties, 363.17 million tonnes of mineralized material with an average KCl grade of 14.68% (equivalent to an indicated mineral resource of 53.35 million tonnes of KCl) have been estimated. For the measured category of the combined properties, 34.77 million tonnes of mineralized material with an average KCl grade of 14.38% (equivalent to a measured mineral resource of 5.00 million tonnes of KCl) have been estimated. Potash mineralization consists of sylvinite and carnallite.

The inferred mineral resource of the combined properties consists of 790.73 million tonnes with an average KCl grade of 12.99% (equivalent to an inferred mineral resource of 102.74 million tonnes of KCl).

Measured mineral resources occur within a radius of 300m of an investigated drill hole, indicated mineral resources within 1,000m of an investigated drill hole minus any measured mineral resources in this area. Inferred mineral resources occur within 2,000m of an investigated drill hole minus any measured and indicated mineral resources in this area.

A summary of the measured and indicated mineral resources included in the updated mineral resource report are presented in Table 1. A summary of the inferred mineral resource included in the updated mineral resource report is presented in Table 2:

ERCOSPLAN has opined that the investigated part of the Passport property contains sufficient resources to publish a Preliminary Economic Assessment and justifies further expenditures of funds to expand the mineral resource.

Passport's President and CEO Joshua Bleak commented, "We are very excited to have this first look at the combined resource with the Hopi tribe, which is very encouraging. Our project has never been in as strong a position as it is today, and we are confident that the PEA that will be released within the next two weeks will make it even stronger."

About the Holbrook Potash Project

Passport Potash Inc. is a publicly traded corporation engaged in the exploration and development of advanced potash properties with its major focus on a previously explored potash property in Arizona. Passport has acquired a strategic position in the Holbrook Basin with land holdings encompassing over 121,000 acres. Passport has entered into a joint exploration agreement with the Hopi Tribe to work towards developing about 13,000 acres of contiguous privately held Hopi land.

Quality Assurance and Quality Control

The standard operating and quality assurance procedures followed by Passport Potash employees have been instituted to make sure that all sampling techniques and results meet international reporting standards. Coring starts when the first significant gypsum interval (Upper Supai Formation) is intersected. Information about the drill holes and the on-site core descriptions are conducted according to international standards (depth intervals, recovery %, lithology, structure, alteration, rock type, weathered profile, sample intervals, remarks). Onsite field geologists collect the cuttings, bag and label them and place a small sub-sample into a chip tray for further treatment. Directly after being retrieved the cores are measured, cleaned, filed logged, packed in plastic poly sheeting and placed into sequentially numbered and labeled core boxes. Material is temporarily stored prior to transfer to the core facility in Apache Junction, Arizona, where significant intervals are dry cut in half. Half core samples are then bagged and carefully packed into boxes and shipped to the Saskatchewan Research Council in Saskatoon.

Passport is utilizing SRC's Potash ICP Analysis package designed for multi-element analysis of potash samples. SRC includes blanks, duplicates and their internal potash 003/004 standards in the analysis. SRC's analytical procedures have been more fully detailed in the NI 43-101 Technical Report, dated 30 March 2012, prepared for Passport Potash by ERCOSPLAN IngenieurgesellschaftGeotechnik und BergbaumbH. SRC is an ISO/IEC 17025:2005 certified facility.

Tim Henneberry, P.Geo., Advisor, and a Qualified Person as defined in National Instrument 43-101, has reviewed and approved the technical content of this news release.
