MONTREAL, QUEBEC--(Marketwired - Jan 11, 2018) - Dundee Sustainable Technologies Inc. ("DST or the Corporation") (CSE:DST)(CSE:DST.CN)(CNSX:DST) is pleased to announce a piloting test program with eCobalt Solutions Inc. ("eCobalt") (TSX:ECS) on a 3-ton bulk mineralized sample from the Idaho Cobalt Project ("ICP"). This testing is planned to test the successful removal of arsenic on a pilot level to less than 0.5% from ICP concentrates using DST's pyrolysis approach, as demonstrated in previous bench scale testing (see January 8, 2018 news release).

The results of this additional testing is expected to provide eCobalt with feasibility level detailed engineering data to assist in costing and sizing of equipment to produce a clean cobalt concentrate with <0.5% arsenic using DST's pyrolysis approach at eCobalt's proposed Cobalt Production Facility. The piloting work will be conducted at DST's facilities in Thetford Mines, Quebec, where previous laboratory work on ICP mineralized material identified that the it is amenable to pyrolysis to produce a clean, low arsenic, cobalt concentrate.

Mr. Brian Howlett, the President and CEO of the Corporation stated, "DST is very pleased with the progress of the work results to the pilot scale testing with eCobalt on this important project. Arsenic removal, handling and safe disposal is important for most known North American sourced primary cobalt and represents a new opportunity for the Corporation's arsenic technology beyond the gold and copper projects that we are pursuing."

Mr. Jean-Philippe Mai, P. Geo., is the Qualified Person who has reviewed, prepared and approved the content of this news release.
