MONTREAL, QUEBEC--(Marketwired - Feb. 13, 2018) - Dundee Sustainable Technologies Inc. ("DST or the Corporation") (CSE:DST)(CSE:DST.CN)(CNSX:DST) is pleased to announce that it has entered into an agreement with the National Research Council of Canada ("NRC") for research services for the analytical characterization of auriferous arsenic-bearing mineral samples (the Service). The Service will provide valuable additional information to DST pursuing its technical work on arsenic-bearing mineralized materials such as arsenopyrite and cobaltite. DST is being provided $99,900 from NRC-IRAP in support of this work.

The goal of the Service to be performed is the in-depth technical characterizations on mineralized materials that have been processed by DST in view of expanding the applications of the Corporation's arsenic vitrification technology. The Services shall be rendered in the first quarter of 2018 at the NRC's Energy, Mining and Environment Research Centre in Ottawa, Mr. Brian Howlett stated, "This program is a logical step in strengthening our approach to arsenical materials and more fully integrate arsenic-removal processes with our arsenic vitrification technology. The Corporation is currently working on development projects in the arsenopyrite and cobalt spaces that will benefit from this work. We would like to thank the National Research Council for their support in a Canadian-developed technology."
