DST signs US$ 1,000,000 agreement for its GlassLock Process

  April 15, 2020

MONTREAL, QUEBEC, April 15th,  2020 – Dundee Sustainable Technologies Inc. (“DST” or the “Corporation”) (CSE: DST) is pleased to announce that it has entered into a commercial agreement (the “Agreement”) with a gold and copper producer (the “Client”) for the utilisation of its GlassLock ProcessTM  (“GlassLock” or the “Technology”).  As part of the Agreement, DST received a US$ 1,000,000 cash payment in return for a one (1) year exclusivity period for the application of its GlassLock ProcessTM on copper smelting operations. The Client maintains an option to renew the moratorium for an additional four (4) consecutive years upon payment of additional US$ 1,000,000 each year.

This decision was made by the Client following the completion of a successful on-site demonstration of the GlassLock in December 2019.  In addition, the Corporation received by the Client a request to submit a proposal to conduct engineering services to evaluate the full-scale implementation of its Technology at their smelter.

As per the Agreement, DST maintains all rights for the application of GlassLock on other precious and base metal projects (excluding copper smelters) associated with arsenic bearing minerals.  DST is currently developing several of these opportunities through testing or engineering studies with other strategic partners. 

The Corporation’s President and CEO, Mr. David Lemieux commented: “With the signature of this agreement, DST achieved a major and important milestone in its history.  After years of research and development, we are finally entering the commercial phase.  This new chapter is full of opportunities, particularly for gold arsenopyrite assets where our technology can make a difference.  This Agreement is sending a strong signal to the industry about the merits of DST’s Technology. We will continue working with our Client for the application of the Technology at their copper smelter, while continuing to develop these arsenopyrite bearing gold projects where the lower costs of GlassLock can generate additional value for our customers and shareholders.”
