Pacific Potash Corp Provides an Update on its Claims in Amazonas Basin

Vancouver, British Columbia - October 12th , 2012 - Pacific Potash Corp Acquires Brazilian Subsidiary and Completes Option Agreement (TSX-V: PP; OTCQX: PPOTF; FSE: P9P, "the Company") is pleased to provide an update on its Amazonas Potash Project in Brazil. The Company has an option to acquire an 80% interest in Western Potash Corp. (TSX: WPX) Amazonas Basin claims, as previously announced via press release dated June 13, 2012.

Representatives from the company traveled to the property in late August and conducted a site visit, property tour and compiled historic and new information on the property and surrounding basin from various government and private sources. All information was compiled and analyzed extensively by company officials, management and Qualified Persons as defined by NI 43-101.

The Company used four basic criteria to review and prioritize its extensive land package;

Environmentally sensitive areas, natural reservations, and indigenous lands

Accessibility (including logistically challenged areas, flooded ground, etc...)


Geomorphology

Geological potential

Based upon this review and prioritization, the Company has reduced its claims in the Amazonas Basin from 1,474,208 hectares to 805,834 hectares. A map outlining the updated property outline may be found at the bottom of the news release. The reduction in the size of the property will focus the Company's exploration efforts on the areas with the highest geologic potential, and significantly reduce the annual government taxes/fees required to maintain the property in good standing. The Company has also commenced an NI 43-101 qualifying report on the Amazonas Potash Property. Pacific Potash is also investigating potential commercial offers form local and international strategic partners to earn an interest on a portion of the Property.

Dean Pekeski, P.Geo and Director of Pacific Potash stated 'Our review, prioritization, and reduction in size of the Amazonas Property has allowed us to define three target areas. These areas will be further studied and poriortized, and we will develop approprite potash exploration programs accordingly. The reduction in the size of the block will save the Company significant amounts of government fees. We can now direct these funds to our exploration program. Our goal remains to identifty significant potash resources within our updated claim block."

Randy Wright of Pan American Fertilizer (CNSX: PAF), the Company's merger partner commented "The new tenement package, the large amount of work being conducted by other Potash companies in the immediate area and the indefinite moratorium on new claims being offered by the Brazilian government in the basin bode well for the future exploration and development of Pacific's Amazonas basin potash property." Further information on the proposed merger can be found in the Company's new release dated September 21st 2012.

About Pan American

Pan American is a Canadian company dedicated to providing fertilizer to a growing global market. The company is focused on the extraction of a specific type of fertilizer called calcium sulphate (also referred to as "Agricultural Gypsum"). To ensure long term development and increase shareholder value, Pan American currently plans to significantly expand its current operational objectives while expanding its asset base by acquiring additional calcium sulphate and other fertilizer related assets.

When used as a fertilizer and as a soil remediator, calcium sulphate is a soft sulfate mineral composed of calcium sulfate dihydrate which is extremely rich in sulphur and calcium. When dissolved in water, the mineral becomes calcium and sulphate sulphur ions, both of which are required nutrients for plants. Calcium sulphate plays a vital role in establishing and maintaining good chemical balance in soil, water and plants, specifically with healthy root development. Ultimately, calcium sulphate increases overall crop quality and yields.
