08:42 AM EDT, 08/18/2025 (MT Newswires) -- Revival Gold ( RVLGF ) on Monday provided "promising" results from a program of metallurgical testing undertaken in collaboration with Dundee Sustainable Technologies (DST), a unit of Dundee Corporation (DC-A.TO).

The company said "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.

"DST's Glasslock Process offers Revival Gold ( RVLGF ) the opportunity to produce a direct-to-smelter saleable gold concentrate from a potential second phase underground sulphide operation following the planned open pit heap leach phase at Beartrack-Arnett," said Revival Gold ( RVLGF ) Chief Executive Hugh Agro.

A 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 company said results from DST metallurgical testing will be presented by its, Vice President, Engineering & Development, John Meyer, at the upcoming Nevada Mineral Processors Division annual meeting taking place August 20-22, in Reno, Nevada.

Shares of the company closed down 0.9% to $0.525 on the TSX Venture Exchange.
