The Treasure Creek discovery and Felix Gold’s new direct smelting claim matter for national security and American industry, and this piece explains how a simpler ore-to-metal path for antimony could speed production, support ammunition and battery supply chains, and revive domestic mining while preserving Alaska’s landscapes.
Felix Gold Company Ltd. says it has found a way to shorten the route from ore to metal for antimony at the Treasure Creek project north of Fairbanks. The company reports that hand-sorted stibnite from the NW Array target can meet or exceed U.S. military-grade concentrate specifications right out of the ground, which changes the economics of small-scale, high-grade operations. That potential means quicker turnaround from extraction to usable metal and fewer processing steps that traditionally add cost and vulnerability to supply chains. For a nation that wants secure, homegrown sources of strategic materials, that matters in practical, Republican terms: less dependence on foreign suppliers and more resilience at home.
Reminiscent of the Fairbanks, Alaska-area mines that supplied high-grade antimony during the World Wars, Felix Gold Ltd. is evaluating a direct shipping ore approach at its Treasure Creek project north of Fairbanks.
Recent test work carried out at independent labs indicates that hand-sorted stibnite from the NW Array target can exceed typical military-grade concentrate specifications and be processed into high-purity antimony metal through either direct smelting or hydrometallurgical methods.
“Start with the ore. It can be excavated, hand-sorted, and delivered as high-grade feed, now shown to exceed U.S. military-grade concentrate specifications as direct ore,” said Felix Gold Executive Director Joseph Webb. “There are no known sources, to the company’s knowledge, of military-grade antimony concentrate in the Western world – and this exceeds that threshold straight out of the ground.”
Antimony is a quiet but essential metal: it strengthens lead for batteries, stabilizes flame retardants, plays roles in semiconductors and alloys, and even figures into certain explosive formulations. The supply chain for these inputs has been thin for years, and reliance on overseas producers introduces strategic risk. A domestic source that can be processed with fewer steps reduces logistical complexity and improves the timeline for putting metal into defense and industrial use. For voters who care about manufacturing jobs, energy independence, and national readiness, a faster path from mine to market is the sort of practical development they can get behind.
Felix Gold said it has secured regulatory permission to take a 1,600-ton bulk sample to test the concept at scale, and mobilization is underway to extract and hand-sort high-grade material. That kind of sampling is a standard, cautious way to validate lab results before any larger build-out, and it gives regulators and local communities a clear window into operations. A focused, small-footprint operation aimed at selectively shipping high-grade ore is different from large open-pit extraction, and the company frames this as a targeted activity that can be done responsibly. If the tests hold up, the model could be replicated at other deposits, offering a template for strategic mineral production across the country.
Work on the direct smelting route is in motion, and the graphic explanation of the process helps make the technical case clear to non-experts. Simplifying steps between extraction and metal production reduces both capital intensity and the time required to produce finished antimony. That matters when defense suppliers need material on predictable schedules and manufacturers need feedstocks without geopolitically risky supply chains. A domestic capability also helps support American jobs, local economies in areas like Interior Alaska, and the broader industrial base that undergirds national power.
Developing domestic antimony is not just an abstract policy win; it affects everyday products and military readiness. Lead-acid batteries still matter for many vehicular and industrial applications, and antimony’s role in alloys and flame retardants touches sectors from construction to electronics. Having Western sources that meet military specifications reduces the chance that strategic inventories will be held hostage by distant governments or fragile logistics. From a Republican perspective, that is sound common-sense policy: strengthen domestic production, protect supply chains, and keep jobs and power at home.
This approach could enable development of a relatively small-scale operation at NW Array, about 15 miles north of Fairbanks, focused on selectively mining and shipping high-grade material for processing into antimony used in ammunition, batteries, flame retardants, semiconductors, and other applications.
To advance this concept, Felix recently secured a 1,600-ton bulk sampling permit from the Alaska Department of Natural Resources (see related story in the current edition of North of 60 Mining News). The company is mobilizing equipment and crews to begin extracting and sorting high-grade stibnite, with work expected to begin in the coming weeks.

Alaska’s vast landscapes offer both pristine scenery and valuable resources, and responsible development can reconcile those priorities. Modern mining techniques combined with selective, small-scale operations can provide strategic minerals without wholesale industrialization of sensitive areas. That balance is exactly what proponents argue for: conservation of scenic and ecological values alongside smart resource development that supports American industry and defense. If managed well, these projects can deliver material benefits while keeping the environment and local communities in view.
