ThermoPotash Compares Favourably with KCl in Nutrient Availability Test

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".
