Potassio do Brasil Intersects 39.94 % KCl at 843.08 m Confirming the World Class Potash Potential of the Amazon Basin-Brazil

BELO HORIZONTE, BRAZIL--(Marketwire - Aug. 19, 2011) -

Potassio do Brasil ("PBL" or the "Company") is pleased to announce the results of Hole BP-AT-11-09, which strongly supports the Company's view that the Amazon Basin contains multiple world class size potash deposits. The Project is located within the Amazon Basin, Amazonas State, Brazil and is adjacent to Petrobras' Fazendinha and Arari Potash deposits (see Figures 1 and 2 below).

Following on from previously announced results (8 September, 2010) from Hole PB-AT-10-02 which included 1.86 meters of sylvinite from 841.78 meters depth grading 32.59 % KCl, Hole PB-AT-11-09 has intercepted 1.82 m of sylvinite from 843.08 meters depth grading 39.94 % KCl.

Hole PB-AT-11-09 is located approximately 1.8 km South West from Hole PB-AT-10-02. Both of these holes are located approximately 10 km North of the Fazendinha Potash Deposit.

Helio Diniz, Managing Director of Potasio do Brasil, comments "The Company's Brazilian based technical team has been working systematically on the Amazon Basin since 2007. Their work concluded that there is potential for multiple potash deposits to be discovered in the basin. The Company embarked upon a drilling program commencing in 2010 to test the technical team's conclusions. The excellent results from Hole PB-AT-11-09 coupled with the earlier results from Hole PB-AT-10-02 validate the geological model and confirm the basin's enormous potash potential."

Hole PB-AT-11-09, located approximately 10 km North of the Fazendinha Deposit, has intersected 1.82 meters of sylvinite from 843.08 meters depth grading 39.94 % KCl. This intercept includes a higher grade zone with 1.59 meters grading 44.52 % KCl. Approximately 47 meters of halite and anhydrite were intersected below the potash horizon and the hole was stopped at 892.45 meters (see Figure 3). The results of PB-AT-11-09 are consistent with management's expectations based on the basin mapping and analysis.

Andre Costa, P.Geo. Project Manager states that, "Within these large basins the potash occurs in extensive sub basins where maximum salinity conditions are reached. We have clearly established that conditions prevailed in the Amazonas Basin similar to that of the Saskatchewan and Ural basins, such that multiple sub basins are developed in specific stratigraphic positions and BPC is in the process of delineating the most recently identified one. Based on the petroleum borehole data we are confident there will be other potash sub basins within the 400 km basin."

According to Helio Diniz "We now have two holes with higher grade potash intercepts than the 16 historic Petrobras drill holes which delineated the + 500 Million tonnes resource at the Fazendinha Deposit. In addition, PB-AT-10-02 and PB-AT-11-09 potash intercepts are located at depths 260 meters closer to the surface than the average depth of the Fazendinha Deposit (1,100 meters depth)."

The Company currently has contracts with two Brazilian owned drilling companies. The Company intends to increase the number of drill rigs on the project to accelerate the delineation of potash resources in the basin.

The Company 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 followed by a bankable feasibility study. If the studies are favorable and permitting proceeds, the project will be developed. The Company forecasts that the total investment in the project could be in the order of US$3.5-4.0 billion with a view to producing 4 million tonnes per annum of potash (KCl). It is the intention of the Company to list on BOVESPA by late in 2012.

Helio Diniz, commented "Brazil is highly dependent upon imported potash to meet the country's fertilizer needs. The development of this basin over time can change Brazil from a net importer of potash to a net exporter of potash. The supply of potash for Brazilian farmers from this project will be accomplished in part through off-take agreements already signed between the Company and two of Brazil's largest Agricultural Co-operatives, CCAB and Coonagro."

All environmental permits and access agreements with surface land holders are in place. The Company employs a best practice policy with respect to maintaining the highest environmental standards and each drill site is progressively reclaimed upon completion.

About Potassio do Brasil Ltda.

Potassio do Brasil Ltda. is a private Brazilian potash exploration company with offices located in Belo Horizonte and Autazes, Brazil, which supports the work being carried out on its project in Amazonas State. Potassio do Brasil has no operating potash mines and has no direct or indirect association with any of the current potash producers either in Canada or elsewhere in the world. The Company holds key mineral rights in the 400-kilometer long Amazon potash basin. Geological, seismic and borehole surveys indicate the basin has similar scale and geological properties as the Saskatchewan basin in Canada.
