Vancouver, British Columbia - March 26th, 2013 - Pacific Potash Corporation (TSX-V: PP; OTCQX: PPOTF; FSE: P9P, "the Company") is pleased to announce the completion of an opinion by Agapito Associates, Inc. ("Agapito") on the feasibility of solution mining in the Amazon Basin. Their report discusses the known geology of the Amazon Basin including depth, grade and thickness of known potash deposits and occurrences and uses that information to develop an opinion on solution mining.

Highlights from the report include the following:

• -.The Nova Olinda Formation contains a cyclic sequence of marine limestones, sandstones, mudstones, and evaporites of varying thickness. In the upper third of the formation, there is a potash bed that contains sylvite, the mineral mined from the deposits found in Saskatchewan.

• -.Potash mineralization at the Fazendinha and Arari properties was identified by Petrobras in the 1970s and 1980s. Grades reported at Fazendinha range from 28% to 33% potassium chloride (KCl) over thicknesses ranging from 0.98 m to 4.58 m. The depth of the potash zone ranges from 1,000 to 1,100 m. At Arari the depth to the potash zone ranges from 995 to 1,300 m. Poorly soluble sulfate minerals were noted in the middle zone between the two sylvite horizons on these properties.

• -.Brazil Potash Corporation's drilling near Autazes, west of the Company's claims, has encountered potash in 13 wells. Potash grades ranged from 15% to 40% KCl, over thicknesses ranging from 1.35 m to 3.13 m. Two wells near Itapiranga, north of the Company's claims, encountered potash, with grades of 23% KCl over 2.20 m and 26% KCl over 4.84 m, respectively.

• -.Potash could possibly extend onto the Company's permits near Arari and Itapiranga. If so, the expected minimum depths of the potash in these areas would be approximately 1,100 m and 1,300 m, respectively.

• -.The ambient temperature at these depths could range from 41 degrees Celsius (?C) to 51 ?C based on average crustal heat flows and the local geology. This temperature range is comparable to the temperature encountered at the Belle Plaine solution mine in Saskatchewan.

• -.Based on the above, the Agapito report concludes that solution mining on the Company's permits is potentially feasible if potash is encountered during exploration drilling, provided that the true thickness of the potash bed(s) exceeds 2 m, and the grade of the potash exceeds 15% K2O (24% KCl). Solution mining of KCl is enhanced if the ambient formation temperature in the potash beds exceeds 40?C.

Dean Pekeski, Director of the Company states "the report from Agapito clearly speaks to the potash solution mining potential of the Amazonas Basin. Although there has been no drilling on the Company's permits to date, the report indicates that should we intersect potash beds of sufficient grade and thickness through our exploration drilling, they are likely to be found at depths amenable to solution mining."
