(DST.CN) develops and commercializes proprietary hydrometallurgical processes for the treatment of complex and refractory materials in the mining industry, focusing on environmentally friendly extraction of precious and base metals from ores, concentrates, and tailings as well as stabilization of contaminants. The company offers the CLEVR process, a cyanide-free technology using sodium hypochlorite to extract gold, silver, nickel, cobalt, copper, and zinc; the GlassLock process, which permanently stabilizes arsenic, antimony, and cadmium from sources including arsenopyrite, enargite, cobaltite, and flue dusts; and technical services to evaluate processing alternatives for mining customers. DST operates primarily in Canada and internationally, targeting mining companies seeking compliant, low-liability solutions; it was incorporated in 1997, changed its name from Nichromet Extraction Inc. in January 2014, and is headquartered in Thetford Mines, Canada, as a subsidiary of Dundee Corporation. Recent developments include the completion of a GlassLock detailed engineering mandate and the sale of non-strategic operations and assets in 2023; participation in an electronic waste material treatment development project announced in June 2023; milestone achievements in the electronic material treatment project in May 2024; and collaborations such as with ESGold on gold-silver green processing and Revival Gold on sulphide concentrate testing using GlassLock in 2025.
