Revival announces results from Dundee Sustainable Technologies collaboration

Revival Gold (RVLGF) announced results from a program of metallurgical testing undertaken in collaboration with Dundee Sustainable Technologies to evaluate the effectiveness of DST’s Glasslock Process on a high-grade sample from the Joss deposit at the Company’s Beartrack-Arnett Gold Project located in Idaho, U.S.A. Highlights: GlassLock Process testing on high-grade underground sulphide material at Beartrack-Arnett boosted the concentrate gold grade 31% and cut the arsenic content by 99% with almost no loss in gold. DST’s GlassLock Process has been successfully tested globally and used at an industrial scale at the Tsumeb smelter facility in Namibia. 3,900-meter core drilling program will be kicked off later this year to continue to test and expand on the high-grade underground potential at Beartrack-Arnett. The DST work was undertaken subsequent to Dundee Corporation’s purchase of a strategic stake in Revival Gold and followed up a previously reported flotation testing program on a 4.6 g/T gold composite from the Joss deposit that yielded a flotation concentrate grading 50 g/T gold, 23% sulphide sulphur and 13.5% arsenic. DST developed a similar arsenopyrite-rich concentrate from Joss samples and following their GlassLock Process the concentrate graded 66.1 g/T gold, 17.9% sulphide sulphur, and 0.19% arsenic. No measurable gold was lost during the GlassLock Process. The primary biproduct from the GlassLock Process is a stable, insoluble, arsenic-rich glass characterized as non-toxic using Environmental Protection Agency’s Method 1311 Toxicity Characteristic Leaching Procedure.
