Felix Gold Limited’s latest tests achieved concentrates with up to 69% antimony and over 85% recovery. With high purity ore and prime Alaskan infrastructure, the company is advancing towards U.S. antimony production—an exciting opportunity for critical minerals investors.
Felix Gold Limited has released encouraging test results from its Treasure Creek Project in Alaska, demonstrating its ability to produce a high-grade antimony concentrate from samples collected at the NW Array and Scrafford prospects. The initial metallurgical test work revealed raw feed grades exceeding 28% antimony, with some samples reaching up to 58% antimony. Notably, the NW Array tests achieved an 85% recovery rate using a combination of gravity separation and flotation processes, resulting in a concentrate grade of up to 69.3% antimony. Meanwhile, tests at the Scrafford prospect produced concentrates in the 60–65% range, with certain heavy liquid separation results exceeding 84% recovery and reaching as high as 96.5% in some instances.
The technical work conducted at PMC Mineral Services Laboratory in British Columbia confirms that the antimony concentrate not only meets premium quality standards—with impurities such as arsenic maintained at or below 0.5% and lead, cadmium, and bismuth at negligible levels—but may also have potential for military-grade applications. This outcome is significant as industry standards typically see commercially traded antimony concentrates grading between 40% and 55% antimony. With recovery efficiencies above 85% and the ability to produce a product in the premium range, Felix Gold Limited is positioning its project to potentially address the growing U.S. need for critically important minerals amid supply chain concerns and rising geopolitical interest.
Beyond the laboratory successes, the project benefits from its strategic proximity to Fairbanks, Alaska, with established infrastructure, road access, and supportive U.S. permitting frameworks. The company is now moving forward with plans to collect composite samples for a comprehensive drill program, further metallurgical testing, and process plant design aimed at commercial antimony metal production via smelting and hydrometallurgical processes. Market engagement and testing to optimize recovery methods, including parallel assessment of gold extraction, underline Felix Gold’s commitment to advancing the project with the prospect of beginning production as early as late 2025.
From a bullish perspective, the exceptionally high-grade antimony concentrate results, efficient recoveries, and alignment with U.S. defense and critical mineral needs bode well for Felix Gold Limited’s strategic positioning. The simplified processing approach proposed could reduce both capital and operating costs, while the strong market tailwinds—as evidenced by record antimony prices and supply deficits—support positive sentiment about the project’s competitive advantage.
Conversely, the bearish viewpoint highlights the inherent risks associated with early-stage project development. The prospect of production remains dependent on favorable feasibility studies, obtaining requisite regulatory approvals, and securing appropriate funding. Delays in environmental studies or any unforeseen challenges during detailed process plant design and additional testing could temper near-term production timelines, adding a note of caution for beginner traders.
Overall, the announcement underscores a promising technical milestone for Felix Gold Limited, while the balance of technical success and project risks will ultimately shape investor sentiment as the project advances through its next stages.
