Government of the Province of San Juan Signs a Decree for the Implementation of Dundee Sustainable Technologies Green Technologies in Argentina

MONTREAL, QUEBEC--(Marketwired - Nov. 11, 2014) - Dundee Sustainable Technologies Inc. ("DST") (CSE:DST) the developer and owner of proprietary technologies to serve the natural resource sector with environmentally friendly procedures, is pleased to provide further information on its progress to date.

On October 31^st, 2014, a decree was ratified in San Juan by the Governor of the Province of San Juan, M. Jose Louis Gioja, in view of implementing DST's proprietary cyanide-free technologies following the visit at DST's plant in Thetford Mines by the Minister of Mines of the Province of San Juan, Argentina and representatives of the University of San Juan.

San Juan Mining S.A. has announced that they will proceed to obtain the financing to build a processing facility using DST's environmentally friendly technologies, including the treatment of arsenic, in the Province of San Juan at an estimated cost of 100 M$. The processing facility shall have a capacity to process 200 Tonnes of concentrate per day (6,000 Tonnes of ore).

DST granted to San Juan Mining S.A. a non-exclusive license for the use of its technology for which DST would receive a 3% Net Smelter Return ("NSR") on all precious and base metals thus produced. San Juan Mining S.A., a private mining company, has a portfolio of over 15 highly prospective exploration properties in the Province's prestigious "Valle del Cura", host to several world class gold deposits.

About DST

The cyanide and mercury free gold extraction process developed by DST, has been recognized as a "green technology" for which DST has been awarded $5,700,000 in grants to date for a demonstration plant, presently under construction in Thetford Mines Quebec 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. The plant is scheduled to go into operation at the end of March 2015.

Over the last ten years DST 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. An engineering study supports DST's claim of having operated a pilot plant showing a gold extraction yield higher than 90% using a closed-circuit chlorination process
