U.S. Gold has selected Glencore Technology’s Jameson Cell flotation technology to enhance gold and copper recovery at its CK Gold Project in Wyoming.
The decision follows extensive engineering, optimisation, and trade-off studies conducted as part of the company’s definitive feasibility study and execution plan. Engagement with Glencore Technology began in late 2024, when the Jameson Cell—first introduced in 1986—was proposed as an upgrade to conventional flotation cells.
Subsequent testing on CK Gold Project ore confirmed the technology’s effectiveness, showing higher gold and copper recovery rates than those reported in the February 2025 prefeasibility study. A trade-off study by Halyard Micon International further estimated that the Jameson Cell could lift the project’s net present value (NPV, 5%) by about $36 million over the mine’s life.
U.S. Gold president and CEO George Bee said:
“Rigorous testing and trade-off studies confirm this technology’s clear advantages over conventional flotation cells, from increased metal recovery to lower power use and a smaller equipment footprint. This strategic decision strengthens the already strong economics of the CK Gold Project and supports our role in domestic strategic metals production. We thank Glencore Technology for its support and performance guarantee as we continue to optimise our project.”
To secure cost certainty, U.S. Gold has obtained a letter from Glencore Technology guaranteeing pricing on unused Jameson Cells—originally purchased for a cancelled project—through October 2025.
Separately, in November 2024, subsidiary Gold King received the final air quality permit for the CK Gold Project from the Wyoming Department of Environmental Quality.
