VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 13, 2012) - Pacific Potash Corporation (TSX VENTURE:PP)(OTCQX:PPOTF)(FRANKFURT:P9P) ("Pacific Potash" or the "Company") is pleased to announce that it has signed an arms-length letter of intent ("LOI") with Moonraker Acquisition Corp. ("Moonraker") effective June 8, 2012, relating to an acquisition by Pacific Potash of all the issued and outstanding securities of Moonraker from the shareholders thereof (the "Transaction"). Moonraker holds an option to acquire Western Potash Corporation's (TSX:WPX) ("Western") Brazilian potash assets.

Potash Exploration in the Amazonas Basin (Brazil)

The property comprises several claim parcels (Figure 1, Western's Claims) that extend from the Amazon River to the centre of the Amazonas Basin, in the same area where Potassio do Brasil, Petrobras, and Vale, among others, are exploring for potash deposits. There has been a large amount of capital and investor interest in the Amazonas Basin area and Brazil recently.

Rio Verde announced in a news release dated May 25^th, 2012, that they had set up a non-brokered private placement for aggregate gross proceeds of up to $15-million. The proceeds from the financing are planned to finance exploration and pre-feasibility studies at its Sergipe Potash Project, to continue exploration of its portfolio of phosphate prospects, for development of the Fosfatar Phosphate Project, and for working capital purposes.

In a news release dated May 31^st, 2012 Potassio do Brasil announced that they had completed a US$58.66 million capital raising to further the exploration for potash at their Amazon Basin Project, which is adjacent to Petrobras' Fazendinha and Arari Potash deposits. Potassio do Brazil, which currently has contracts with two Brazilian drilling companies, has indicated that it will continue drilling until a potash resource of sufficient size to merit economic studies has been outlined. Once this is completed, a pre-feasibility study will be undertaken, which will be followed by a definitive feasibility study. It is the intention of Potassio do Brazil to raise between $300 to $500 Million for their IPO on BOVESPA (Brazilian Exchange) in Q1, 2013.

Two deposits owned by Petrobras-Arari and Fazendinha-are located 20 and 40 km west of the property being optioned by Pacific Potash. These two deposits have reported historic resources as follows*:

Fazendinha - 520 Mt @ 28.8% KCl

Arari - 659 Mt @ 17.7% KCl

NI 43-101 Disclosure

Jody Dahrouge, P.Geol., a qualified person for the purposes of NI 43-101 supervised the preparation of the technical information in this news release.

* The resource estimates for Fazendinha and Arari potash deposits are historic in nature and are not considered National Instrument 43-101-compliant resource estimates. Resource estimates were disclosed by Redstone Resources (J. Orestes Santos, 2009). Although the resource estimates are relevant, they have not been verified. A qualified person has not done sufficient work to classify the historic estimates as current mineral resources. Pacific Potash is not treating the historic estimates as current mineral resources and therefore the historic estimates should not be relied upon.
