TORONTO, ONTARIO--(Marketwire - Aug. 11, 2010) - Amazon Mining Holding Plc (TSX VENTURE:AMZ) ("Amazon" or the "Company"), is pleased to provide encouraging results from nutrient availability tests completed on its proposed ThermoPotash product. ThermoPotash is shown to provide similar availability of potassium nutrient (K2O) as muriate of potash (KCl) in both clayey and sandy soils. In addition, tests showed that ThermoPotash is also a source of calcium and magnesium, two essential macronutrients not available in KCl.
The tests were performed by Dr. Gaspar Korndorfer at the University of Uberlandia, Minas Gerais, Brazil, in accordance with a recognized industry measure of nutrient availability in soils. Tests were completed using equal amounts of contained potassium (K2O) from ThermoPotash, muriate of potash (KCl) and verdete, the unprocessed source rock for ThermoPotash. Samples were prepared to replicate fertilizer distribution of 200 kg/ha and 400 kg/ha of K2O in clayey and sandy soil, samples were left for 90 days in a closed system and levels of K2O available to plants were measured using a Melich 1 acid mixture. Melich 1 extractor is often called the double acid test. It uses a dilute mixture of hydrochloric (0.05N HCl) and sulfuric acids (0.025N H2SO4), to retrieve the nutrients in the soil.

The tests show that KCl and ThermoPotash are statistically equivalent in making potassium available to plants as a fertilizer. Verdete unprocessed was not able to impact potassium levels in the soil, showing that our process work is both necessary and effective. Levels of other essential macronutrients for plant growth, calcium and magnesium, were also measured. ThermoPotash was also very effective in delivering these nutrients, which are not present in KCl. Full results with statistical variances will be made available on SEDAR.
In addition, a nutrient leaching test being conducted at the University of Uberlandia will compare how much potassium fertilizer is washed away by regular rainfall.
Commenting Agronomist Dr. Gaspar Korndorfer, "We are encouraged by this result; it shows that the pyrometallurgical process has been effective at liberating the nutrients for plant uptake, showing ThermoPotash can be an effective multi-nutrient fertilizer. We will conduct more tests to support the slow release claims of the proposed product".
