DST Provides an Update on a Cobalt Testing

MONTREAL, QUEBEC, July 11, 2018 – Dundee Sustainable Technologies Inc. (“DST” or the “Corporation”) (CSE: DST) is pleased to announce an update on the pilot test program with eCobalt Solutions Inc. (“eCobalt” – TSX: ECS).  The work was performed on an eight (8) ton bulk mineralized sample from the Idaho Cobalt Project (“ICP”).  The goal of this testing was to identify the set of conditions for the successful removal of arsenic on a pilot level to less than 0.5% from ICP concentrate using a fluidized bed roaster.

Several pilot runs were executed at varying temperatures, oxygen content and duration in DST’s fluidized bed.  Given the limited amount of concentrate available for additional fluidized bed pilot scale runs, bench scale tests using a rotary kiln were conducted at Expert Processing Solutions (“XPS”), a DST partner laboratory using the defined set of conditions.  Additional pilot scale testing is scheduled for the third quarter of this year. 

The arsenic removed from the ICP concentrate during piloting was successfully stabilized using DST’s patented vitrification approach.  A glass product containing more than 20% arsenic (As) was produced and successfully met the requirements of the U.S. Environmental Protection Agency’s (“EPA”) Toxicity Characterization Leaching Procedure (“TCLP”, Method 1311) and the Synthetic Precipitation Leaching Procedure (“SPLP”, Method 1312).

Mr. Brian Howlett, the President and CEO of the Corporation stated, “The technical team at DST continues to work with eCobalt on the set of operating parameters that will result in a successful project that will combine arsenic removal with DST’s patented arsenic vitrification process.”

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