MONTREAL, QUEBEC – TheNewswire - July 13, 2023 – Dundee Sustainable Technologies Inc. (“DST” or the “Corporation”) (CSE:DST) is pleased to announce that its Board of Directors has approved the Corporation’s decision to divest from a portion of its operation and assets located at its Thetford Mines technical facilities. DST has entered into an agreement with Société Asbestos Corporation Limited (TSX-V: AB.H)(“SAL”), a Mazarin Inc. (TSX-V: MAZ.H) subsidiary, for SAL to purchase the remaining portion of a 3,800 tonne processing contract (see Press release April 1st, 2021) and its associated processing plant equipment and utilities (the “Transaction”).

As part of the Transaction, and via a dedicated asset purchase agreement (the “Agreement”) signed on July 13th, 2023, DST will receive an amount equivalent to eight hundred and forty-six thousand dollars (CA$846,500), in return for the operation contract and processing plant equipment. DST’s objective is to benefit from the sale of the processing contract and plant equipment and to allow for the Corporation to focus on the development and commercialization of its flag ship CLEVR™ and GlassLock™ Processes.  

“We would like to thank all of those that have contributed over the years to the creation of this successful processing operation at DST. This Transaction is part of DST’s strategy to divest from a portion of its operation and assets which are not directly associated towards the development and commercialization of the Corporation’s proprietary Technologies.” commented Mr. Jean-Philippe Mai, President and CEO.

As part of DST’s proprietary Technologies commercialization efforts, the Corporation has just initiated a detailed engineering mandate (the “Mandate”) with a gold mining company (the “Customer”). The Mandate consists in detailed engineering deliverables for a plant utilizing DST’s proprietary GlassLock Process™ (“GlassLock” or the “Technology”) for the stabilization of legacy arsenic bearing material at the Customer’s operating gold mine in West Africa (see Press release July 10th, 2020).

The Transaction allows for the Corporation’s full commitment towards the execution of the Mandate. The mandate is expected to last over a period of 4 months and will be conducted by DST’s engineering team in Thetford Mines.
