TORONTO, Nov. 24 /CNW/ - Amazon Mining Holding Plc (TSX-V symbol: "AMZ") ("Amazon" or the "Company") is pleased to announce it has staked a large mineral occurrence of a potash bearing rock known as verdete slate ("Verdete"), which is believed to be uniquely suited to Brazil's fertilizer needs. The Cerrado Verde project ("Cerrado Verde") consists of 84 claims covering 165,069 hectares and is located on the western part of Minas Gerais state, in the heart of the country's agricultural region.

The Cerrado Verde development focus is to achieve the economic recovery of potash from sedimentary deposits of the Serra da Saudade Formation. The main potassium-bearing minerals of Verdete are glauconite (a hydrated potassium-iron silicate) and sericite (a monoclinic, basic potassium aluminosilicate of the mica group), with K(2)O contents ranging from 5% to 14%.

VALE (formerly CVRD) controls a significant block of exploration licenses adjacent to Cerrado Verde. VALE's properties were staked shortly after Amazon's claims. The accompanying map shows each company's titles holdings; Amazon's claims are labelled FVS for the Brazilian operating subsidiary. Amazon controls the majority of the Verdete outcrop.

Thermo-Potash and Agricultural History

Amazon is investigating the viability of applying a pyrometallurgical treatment process to deliver a semi-soluble thermopotash product or directly combining the Verdete with a phosphate rock to create thermophosphate potash. Pyrometallurgical treatment is commonly used in the production of high quality phosphate. Amazon has been able to access 25 years of agronomical and metallurgical studies from Brazilian Universities and Technological Centers that suggest thermopotash is the ideal fertilizer product for Brazil's nutrient poor, well drained acidic soils. Thermophosphate is a premium product in Brazil and one that has been successfully marketed locally for over 40 years. It is recognized for its long retention time in soils, which is important in an environment where heavy tropical rains often wash away, or significantly dilute, highly soluble product nutrients such as KCl (potassium chloride, most commonly used potassium mineral for fertilizer).

Research by Dr. Eichler (1983), Agronomic Engineer, showed that a mixture of 50% Verdete and 50% magnesian limestone, heated at 1,100 degrees C ("TKL") is an efficient source of potash. Importantly, TKL and KCl (which is imported into Brazil from international markets), had equivalent yield impacts despite the lower concentrations of potassium in the former. The thermopotash product also had a longer residual impact on crops over successive plantings.
