Company Dundee Sustainable Technologies Inc.

Dundee Sustainable Technologies Inc. is engaged in the development and commercialization of technologies for the treatment of materials in the mining industry. Through the development of proprietary processes, the Company extracts precious and base metals from ores, concentrates and tailings, while permanently stabilizing contaminants, such as arsenic, antimony and cadmium. Its main focus is the commercialization of its two processes (the Technologies). As part of the commercialization process, it has branded these technologies as the CLEVR Process (cyanide-free gold extraction) and the GlassLock Process (permanent arsenic sequestration in glass). The CLEVR Process is an advanced process for the extraction of precious and base metals using sodium hypochlorite to provide a cyanide-free alternative for the exploitation of gold deposits. The GlassLock Process is a method for the permanent stabilization of arsenic from numerous sources, such as arsenopyrite, enargite, cobaltite and others.
