MONTREAL, QUEBEC, November 17, 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.

Following the successful testing of the ore received in October 2014 from a South American gold mining operation, DST will be receiving 10 to 20 tonnes of ore for testing in its pilot plant in order to establish the feasibility of processing the material through its demonstration plant.

The sample furnished to DST for testing contained the following:

Au (g/t) Ag (g/t) ST (%) Fe (%) Ca (%) Cr (%) Mn (%) Pb (%) Ti (%) Zn (%)
445 19 0.15 58.7 0.44 0.08 0.24 0.05 1.64 0.07

Initial testing, using DST’s extraction process on the material, achieved gold recoveries in excess of 99%. This material may be processed by DST, at a rate of 15 tonnes per day, once the demonstration plant becomes operational in March 2015.
