Felix Gold Limited has been selected by the U.S. Department of Energy (DOE) to enter award negotiations for a financial grant of up to US$18 million to support the Treasure Creek Antimony Pilot Processing Facility in Alaska.

The federal funding is non-dilutive and will be administered through the DOE Advanced Mining and Mineral Production Technologies Office under the Infrastructure Investment and Jobs Act Mines & Metals Capacity Expansion program. Felix Gold was selected alongside eight other projects nationally from a total pool of US$162 million.

The funding structure includes a proposed company cost share of 26.8%, amounting to approximately US$4.8 million, which will be provided in-kind through the delivery of ore from the Alaskan project.

“The U.S. Department of Energy has selected Felix Gold for up to US$18 million because of what we are building: U.S. ore to U.S. metal.”

— Joe Webb, Executive Director

The company established Frontier Antimony Refinery Corp. as a wholly owned Delaware subsidiary to act as a dedicated U.S. platform for antimony refining, metal production, and downstream development utilizing feedstock sourced directly from Treasure Creek.

Previous operations at the site saw the company extract approximately 30 tonnes of high-grade massive stibnite vein material in June 2026 under initial bulk sample permit operations. Felix Gold is actively continuing the extraction of massive stibnite mineralisation while targeting the award of a multi-year mining permit by June 2027.

The award negotiations with the DOE are expected to take up to 120 days from August 18, 2026. During this period, Felix Gold will work alongside the federal agency to finalise the specific scope of work, budget, and schedule for the pilot processing facility. The final funded scope will focus on the highest-value elements of the program following an indicated federal share adjustment to US$18 million.

The selection remains subject to the successful completion of negotiations, the implementation of designated mitigation measures by the DOE Office of Research, Technology and Economic Security, and the formal execution of a funding agreement by a DOE Grants Officer.
