Passport Potash Retains ERCOSPLAN to Complete Initial Resource Estimate on Holbrook Basin Project

VANCOUVER, BRITISH COLUMBIA–(Marketwire – Nov. 28, 2011) – Passport Potash, Inc. (the “Company”) (TSX VENTURE:PPI)(OTCQX:PPRTF) is pleased to announce that it has engaged ERCOSPLAN Ingenieurgesellschaft Geotechnik und Bergbau (ERCOSPLAN) to complete its initial resource estimate on its Holbrook property holdings. All drilling completed to date as well as historical drilling will be reviewed and the Company anticipates an initial resource estimate to be completed in Q1 2012. Subsequently ERCOSPLAN will incorporate all new drill data and seismic work currently ongoing on Passport’s east side holdings in an updated resource estimate by Q2 2012.

ERCOSPLAN is recognized by international financial institutions and regulators around the world for their potash exploration and development expertise. ERCOSPLAN’s experts are members in good standing of relevant professional organizations and have extensive experience in the potash industry. ERCOSPLAN’s clients include some of the largest potash exploration and mining companies in the world. As the successor to the former Kali-Ingenieurbüro Erfurt, ERCOSPLAN is a specialist consulting and engineering group whose core activities include project management in all aspects of the extraction and processing of industrial potash and mineral salts.

“We are delighted to have ERCOSPLAN assist us in completing our initial resource estimate. Should the initial resource estimate justify further work, we would anticipate a working relationship that will involve ERCOSPLAN in further development of the Property. ERCOSPLAN’s experience in the potash space is unrivalled and we look forward to working with them to develop our Holbrook Basin Project”, states CEO Joshua Bleak.

The Company would also like to announce that it will no longer be working with SRK Consulting on the Holbrook Basin project. SRK was unable to commit the resources to complete the initial resource estimate in a timeframe that was acceptable to the Company. The Company thanks SRK for completing the NI-43101 Technical Report dated November 1, 2011, which can be viewed online at www.sedar.com.
