Felix Gold has started open-cut extraction of high-grade antimony ore in Alaska and incorporated a US refining platform, moving closer to establishing a domestic ore-to-metal supply chain targeting operation by end 2027.
- Bulk sample extraction commenced at Bundtzen Vein
- Frontier Antimony Refinery Corp. established for US refining
- Smelter feasibility and site selection progressing materially
- Near-surface gold mineralisation expanded at NW Array
- Cash balance decreased to $9.6 million after exploration and acquisition spend
Bulk Sample Extraction Underway at Treasure Creek
Felix Gold (ASX:FXG) has begun open-cut extraction of massive stibnite ore at its Bundtzen Vein in Alaska, marking a significant operational milestone. The ore is being hand-sorted, graded, and bagged into one-tonne bulk bags, with stockpiles now positioned in Seattle for potential toll treatment. This extraction is authorised under a permit allowing up to 1,600 tons through December 2029, notably without federal regulatory hurdles such as NEPA, streamlining the approval process.
Selected samples from these veins have previously returned ultra-high antimony grades, with assays up to 71.9% Sb, although these are from select samples and not necessarily representative of the entire vein system. The Alaska Department of Natural Resources has accepted Treasure Creek into its coordinated permitting process, advancing mine engineering and permitting for expanded operations materially during the quarter.
Frontier Refinery Corp. Established to Anchor US Metal Production
To complement ore extraction, Felix Gold has incorporated Frontier Antimony Refinery Corp. in Delaware as its wholly-owned US refining, metal production, and marketing platform. Frontier is tasked with purchasing ore from Felix Gold and is actively assessing the feasibility of constructing a dedicated US smelter. Site selection and feasibility work have progressed materially, building on prior assessments by the Worley Group.
Negotiations for toll treatment with third-party processors continue, although no binding agreements have been reached yet. The corporate structure of Frontier is designed to facilitate access to US capital markets and government funding programs, aligning with the strategic importance of antimony to US national interests.
Exploration Expands Gold and Antimony Potential
Drilling at the NW Array prospect continues to reveal a shallow, flat-lying oxide gold system near surface. Final assays from 2025 include 29.26 meters at 2.16 g/t gold from 13.41 meters depth, including a higher-grade zone of 21.03 meters at 2.83 g/t gold. Earlier results reported 37.65 meters at 2.02 g/t gold, highlighting consistent mineralisation within the same structural corridor as antimony.
This dual commodity potential; gold and antimony coexisting within one project area; offers a strategic advantage by leveraging a single permitting and engineering effort for two products. The JORC Inferred gold resource remains steady at 831,000 ounces, with the Kinross Fort Knox mill located just 30 kilometers by road, subject to commercial arrangements.
Corporate Developments and Cash Position
Ernst & Young was appointed as auditor during the quarter to fill a casual vacancy, pending shareholder approval at the next general meeting. The board also approved a proposed grant of 6 million options to Executive Director Joseph Webb, subject to the same approval process.
Cash and cash equivalents fell by $4.5 million to $9.6 million by quarter-end. The outflows included $2 million on tenement acquisitions, $0.6 million on capital expenditure supporting the bulk sample program, and $3.4 million on exploration and evaluation activities. Operating cash outflows were $0.9 million, primarily covering corporate costs across Alaska and Australia. Financing activities contributed $2.5 million from option exercises.
Pathway to US Ore-to-Metal Supply Chain
Felix Gold aims to commence small-scale mining operations by the end of H1 2027, establishing the first US domestic supply chain for antimony ore to metal. The company targets the smelter to be operational by end 2027, creating a new critical minerals supply chain of strategic importance to the US government.
Workstreams advancing include expanding drilling footprints, progressing permitting documents such as the “Plan of Operation,” completing mine site feasibility studies, and continuing smelter site selection and feasibility. Engagement with US government bodies on offtake agreements remains ongoing.
While the company has no JORC-compliant antimony resources or economic studies yet, and production targets remain conceptual, these coordinated advances across extraction, refining, permitting, and exploration signal tangible progress toward Felix Gold’s ambitious US ore-to-metal vision.
Bottom Line?
Felix Gold is methodically building the infrastructure and regulatory groundwork for a US-based antimony supply chain, but execution risks around permitting, commercial agreements, and funding remain critical to watch.
Questions in the middle?
- Will Felix Gold secure binding toll treatment or smelter construction agreements in the near term?
- How might ongoing exploration results at NW Array influence the project’s economic profile and financing options?
- What level of US government support or funding could Frontier Refinery Corp. realistically access given antimony’s strategic status?
