Revival Gold Inc. (TSXV: RVG, OTCQX: RVLGF) has taken another significant step in unlocking the full potential of its Beartrack-Arnett Gold Project in Idaho. In partnership with Dundee Sustainable Technologies, a subsidiary of Toronto-based Dundee Corporation (TSX: DC.A), the company recently wrapped up a series of metallurgical tests that could have lasting implications for gold extraction, and handling problematic byproducts like arsenic, in the U.S. and beyond.
Revival Gold had plenty of reason to scrutinize high-grade samples from the Joss deposit at Beartrack-Arnett. Gold mining rarely progresses in straightforward chapters, needing both technical breakthroughs and solutions for complex environmental issues. The company’s collaboration with Dundee Sustainable Technologies (DST) offered just that, thanks to DST’s patented GlassLock Process™, already proven at industrial scale in other parts of the world where gold comes tied up with arsenic-rich material.
The results of the test program are compelling. DST’s GlassLock Process™ managed not only to boost the gold grade in concentrate from the Joss deposit by 31%, taking it to 66.1g/T, but also cut arsenic content by an eye-popping 99%, down to just 0.19%. This was achieved without any measurable loss of the precious metal. In mining, where both efficiency and risk mitigation are relentless focuses, seeing a one-third gain in gold content paired with a nearly complete elimination of arsenic is something worth talking about. The process also trimmed sulphide sulphur content by 24%, which bodes well for environmental management.
But it’s not just about what gets taken out of the ore; it’s also about what’s left behind. The GlassLock™ Process creates a stable, non-toxic glass containing arsenic, a byproduct that’s been rigorously tested using the Environmental Protection Agency’s standards to ensure it won’t leach toxins into the environment. For miners and regulators alike, this kind of outcome starts to look like the gold standard for responsible resource development.
This progress arrives on the back of Dundee Corporation’s strategic investment in Revival Gold, underscoring the conviction both parties have in the Beartrack-Arnett project, and in the role innovation can play in bringing difficult mineral deposits into productive, profitable use. It’s not lost on analysts that DST’s process stands among relatively few proven at commercial scale, notably at Dundee Precious Metals’ smelter in Namibia, which means Revival Gold isn’t merely conducting laboratory experiments. Instead, the team is employing solutions that have already demonstrated success when scaled up to industrial levels.
As Hugh Agro, Revival Gold’s President and CEO, put it, the DST partnership opens the door to producing a direct-to-smelter, saleable gold concentrate from what could become a second phase, underground sulphide mining operation at Beartrack-Arnett. This would follow the open pit heap leach phase already planned for the site, meaning Revival Gold is expanding its roadmap, not just inching closer to production, but broadening the possibilities for future growth.
The story isn’t just about metallurgy or corporate partnerships. The company plans to build on this momentum with a fresh 3,900-meter core drilling campaign later this year at Beartrack-Arnett, pushing to both test and potentially expand the high-grade underground portion of the project. It’s a move designed not just to validate the current approach, but perhaps to reveal more surprises in the geology.
For those tracking the project, more details about these DST metallurgical results will be unveiled during the Nevada Mineral Processors Division annual meeting in Reno from August 20-22, 2025. With technical oversight from Revival Gold’s Vice President, Engineering & Development, John Meyer, this project is benefiting from leadership with deep mining expertise and a focus on responsible growth.
With Revival Gold planning further drilling and public presentations, the Beartrack-Arnett project is shaping up as an early case study in the future of gold mining, one where technical innovation, environmental stewardship and commercial opportunity might actually coexist without compromise.
