Dundee Sustainable Technologies Inc. Innovates in Nickel Extraction

MONTREAL, QUEBEC -- (Marketwired) -- 05/23/14 -- Dundee Sustainable Technologies Inc. ("DSTI" or the "Corporation") (CSE:DST), the developer and owner of proprietary technologies to serve the natural resource sector with environmentally friendly procedures, is pleased to announce an innovation in the nickel extraction.

The Corporation is pleased to report the successful application of its patented proprietary process for nickel extraction from laterites for the production of nickel sulfate. This new concept was applied on laterites from Guatemala, Cuba and the United States, and achieved a nickel extraction ranging from 95% to 97%, at ambient pressure and moderate temperature, over a short period of time.

This approach has greatly simplified the collection of nickel from laterites as per the following table:

About Dundee Sustainable Technologies, a company controlled by Dundee Corporation

The cyanide and mercury free gold extraction process developed by DSTI, has been recognized as a "green technology" for which DSTI 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 in mid-January 2015.

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. An engineering study completed within the last 12 months supports DSTI's claim of having operated a pilot plant showing a gold extraction yield higher than 90% using a closed-circuit chlorination process.
