Dundee Sustainable Technologies Inc. ("DSTI") (CSE:DST) the developer and owner
of proprietary technologies to serve the natural resource sector with
environmentally friendly procedures, is pleased to announce an update on its
cyanide and mercury-free gold extraction processes. 


Demonstration Plant

The Company commenced the building of a $27 million demonstration plant located
in Thetford Mines in the Province of Quebec in June 2013 and expects the plant
to be commissioned before the end of the current year. Using the DSTI
proprietary cyanide-free gold extraction process. The demonstration plant will
handle concentrates at a rate of 15 tonnes per day These DSTI technologies have
been recognized as a "green technologies" for which DSTI has been awarded
$5,700,000 in grants to date for the construction of the demonstration plant of
which $700,000 has been provided by the Government of Quebec and $5,000,000 by
the Government of Canada through the Sustainable Development Technology Fund.


Successfully Demonstrated

DSTI's cyanide and mercury-free gold extraction process was successfully
demonstrated in its Thetford Mines laboratory and pilot plant. A great variety
of ores and concentrates from 22 different countries, totalling over 100 Tonnes
of material and over 1 000 hours of operation, were tested. Gold recoveries were
above 90% in all cases and above 95% in most cases.


DSTI's technology as utilized in its pilot plant have established, as supported
by engineering studies, a gold extraction yield higher than 90% using a
closed-circuit Bromine-assisted chlorination process."

(i) Flotation concentrates requiring pre-treatment by oxidation

The pre-commercialization demonstration plant will have a capacity of 15 tonnes
per day in order to asses on a pre-industrial scale DSTI's chlorination
extraction technology under continuous operating conditions. The demonstration
plant will serve as a reference for the establishment of full scale plants
operating with the same technology.


About DSTI

Over the last ten years DSTI has tested over 50 different gold deposits, both
oxide and sulfide ores at the lab level and at its pilot plant. These tests
have, consistently achieved gold recoveries in excess of 90%, using chlorination
instead of cyanide. In addition, the tailings from the process are inert from
toxic substances and as result meet environmental norms. 


To date the Company has obtained 25 patents in 19 countries for its technologies
for the extraction of precious metals and base metals as well as the
neutralization of arsenic and production of fertilizer and has 14 pending patent
applications worldwide for its technologies.
