Working on this basin for five years gave me strong understanding of the drilling program logistics, drilling methods, stratigraphycal correlations, depositional environments, structural constraints, mineralization spatial distribution and seismic correlations. This knowledge will be important to achieve positive potash intercepts and consequently advancing to the next stages. All the efforts will now be focused on the upcoming drilling program in order to confirm and evaluate the potash mineralization to be found on Pacific Potash claims that would be developed into potash resources on this new and already confirmed world class potash basin."

Mr. Costa's vast knowledge of a previously almost non-explored basin will be invaluable to the Pacific Potash team. Over the last five years in the Amazonas basin, Mr. Costa has been instrumental in compiling historic data, unlocking the potash sequences and basin geometry for Potash Brazil. He has overseen the drilling of over 20 potash wells in the basin, supervised the compilation of data for Potash Brazil's technical reports, and from a potash exploration perspective, he is one the most knowledgeable individuals regarding the basin.
