Dundee Sustainable Technologies Enters into an Agreement for the Treatment of Arsenical Flue Dusts with a Major Copper Mining Company

  September 15, 2015

MONTREAL, QUEBEC, September 15, 2015 – Dundee Sustainable Technologies Inc. (“DST”) (CSE: DST) is pleased to announce that it has entered into an agreement with a major copper mining company (the “COMPANY”) for the treatment of arsenic-bearing flue dusts (the “Flue Dusts”) produced by the COMPANY’s operations, using DST’s proprietary Technology.

The objective of this Agreement is to establish a two-phase approach aimed, on a first phase, to demonstrate the DST process in a 1-Tonne per day plant (the “Plant”), with the ultimate goal of defining the terms for the treatment, in phase two, of the Flue Dusts on a commercial basis.

Arsenical Flue Dusts are produced through copper smelting of arsenical ores. During the smelting-converting process of copper most of the arsenic is volatilised and reports in the Flue Dusts as arsenic trioxide along with finely divided metal or metallic compounds.
