DST Initiates Gold Project and files new patents in China

  December 18, 2018

MONTREAL, QUEBEC, December 18, 2018 – Dundee Sustainable Technologies Inc. (“DST or the Corporation”) (CSE: DST) is pleased to announce the filing of new patents in China and the commencement of a metallurgical test program with a Chinese gold processing company (the “Chinese Co.”) on high-grade gold and arsenic bearing material.

Mr. Brian Howlett, President and CEO commented, “Management of DST recently returned from a trade mission to China in cooperation with the Government of Canada and the Mining Suppliers Trade Association. During this trip management met with numerous miners, mineral processors and engineering companies in the gold and base metals sectors. During these meetings we were constantly reminded that the environment is front and center for the Chinese mining industry and we are confident that there will be significant interest in the Corporation’s patented gold extraction and arsenic stabilisation technologies. Senior representatives of every company we met used the term Green Mountains and Clean Rivers.”

As a result of these meetings, DST initiated preliminary lab scale test work with a Chinese Co. from which it has received high-grade gold and arsenic bearing samples (“Project Material”) to test the efficacy of the Corporation’s cyanide-free gold extraction and arsenic vitrification technologies.

The Project Material  has been received at DST facility located in Thetford Mines, Quebec. The Project Material consists of two (2) distinct samples.  The first sample is representative of an arsenical dust product which requires to be permanently stabilized by the Chinese Co. and the second sample is a high-grade gold calcine material which requires an efficient and cyanide-free gold recovery process. The material contains grades ranging from 5% to 10% arsenic for the dust product and between 50 g/t to 60 g/t of gold for the calcine material. This test work is part of a phased development approach and is intended to determine the amenability and applicability of DST’s arsenic and gold processes on the Project Material. Results are expected early in 2019.

DST has recently filed patents for the treatment of arsenic bearing material in China: Patent application entitled “Method for Vitrification of Arsenic and Antimony.”, Patent application entitled “Arsenic Glass and Method of Fabrication Thereof”. These patent applications will become the foundation for protection and development of DST’s arsenic vitrification IP in China.

DST has been issued similar patents in the USA and has filed patent applications for this Technology in Canada, Argentina, Australia and several countries through the Patent Cooperation Treaty (PCT).

DST’s gold extraction and arsenic vitrification technologies are becoming attractive techniques worldwide for the treatment of material considered to contain too much arsenic to be exploited using conventional approaches or for companies seeking cyanide alternatives.

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