VANCOUVER, BC, Sept. 8, 2026 /PRNewswire/ -- American News Group News Commentary - Antimony spent decades as an industrial afterthought, a flame retardant additive and a battery alloy that almost nobody outside the chemicals trade thought about. It is now a national security line item. Future Market Insights values the global antimony market at roughly US$2.5 billion in 2026 and projects approximately US$4.5 billion by 2036, a compound annual growth rate of about 6.2%. Capital has already responded, with governments and lenders putting billions behind Western supply. What money cannot buy is time, and the constraint on replacing Chinese antimony is not funding. It is how long it takes to permit a mine.
Active Companies from around the markets with current developments this week include: RUA GOLD Inc. (OTCQX: NZAUF) (TSX: RUA) (NZX: RGI), Perpetua Resources Corp. (Nasdaq: PPTA), United States Antimony Corporation (NYSE: UAMY), Americas Gold and Silver Corporation (NYSE American: USAS), and Nova Minerals Corp. (NYSE American: NVA).
Forecasters size the category differently but agree on direction. Emergen Research puts the market at about US$1.31 billion in 2025 rising to roughly US$2.5 billion by 2035, a compound annual growth rate of around 6.6%. The variance between houses reflects what each counts as antimony revenue rather than any disagreement about demand.
The reason the metal repriced sits in Beijing. In August 2024 China introduced export licensing on six antimony product categories, including antimony ore, antimony metal, antimony oxide and, pointedly, gold-antimony smelting and separation technology. In December 2024 it banned antimony exports to the United States outright. Antimony metal prices roughly doubled in the aftermath. China accounts for roughly half of global output, and the United States imports more than 85% of what it consumes.
Washington responded the way governments respond to a supply shock in a metal that goes into ammunition primers, armour-piercing rounds, night vision equipment and hardened alloys. Antimony was formally designated a critical mineral by both the United States and Canadian governments, and the Defense Logistics Agency announced plans to stockpile it. The practical difficulty is that there is no quick fix. The United States has no operating primary antimony mine, and a deposit takes years to permit and build no matter how urgent the need.
What follows is that the sector has split into distinct strategies for attacking the same clock. Some are buying scale with federal money and accepting the wait. Some are bolting antimony recovery onto ground that is already permitted and already producing. Some are trying to reach pilot output from a standing start. And a narrow category sits apart: antimony deposits already inside a permitting process, in jurisdictions aligned with Western supply chains, carrying enough gold alongside the antimony to be economic on their own terms. There are not many of them anywhere in the world.

RUA GOLD Inc. (OTCQX: NZAUF) (TSX: RUA) (NZX: RGI) reported on September 8, 2026 the highest-grade drill results to date from its Auld Creek gold-antimony project in the Reefton Goldfield on New Zealand's South Island. The headline number is unusual by any standard: hole ACDDH119 returned 0.6 metres grading 82.9 grams per tonne gold together with 24.80% antimony.
A single narrow intercept, however striking, is not a deposit. What gives the release its weight is that the high grades sit inside a wider pattern. ACDDH112 returned 2.85 metres at 9.29 g/t gold and 13.71% antimony, including half a metre at 40.5 g/t gold. ACDDH107 returned 1.9 metres at 10.1 g/t gold with 5.88% antimony, and ACDDH086 returned 2.75 metres at 15.4 g/t gold with 3.60% antimony. Alongside those, ACDDH104 cut 32 metres at 2.11 g/t gold and ACDDH108 cut 11.3 metres at 6.11 g/t, which is the kind of width that matters for a mine plan rather than a headline.
The Company describes the Auld Creek resource as extending over 1,000 metres in length and to more than 500 metres in depth, and says it remains open in all directions. Drill targeting was guided by structural mapping of the Fraternal Fault zone, which the Company reports at an overall orientation of 186 degrees dipping 84 degrees west, with intersecting shears and breccias oriented at 354 degrees on a moderate plunge. Drilling against those structural guides has demonstrated strong continuity of mineralization and what the Company characterises as a high success rate against planned targets.
Two features of the program are worth separating out. In certain shoots gold and antimony grades increase with depth, with visible gold observed in some intervals. In others, mineralized widths increase, with discrete hanging wall and footwall zones of higher antimony grade enveloping a broad zone running roughly 2 to 3 grams per tonne gold. The first pattern points to grade. The second points to tonnage. A deposit that shows both is a more flexible engineering problem than one that shows only one.
"These exceptional exploration results are informing the mine plan and reinforcing the significant development potential of the Auld Creek Project," said Robert Eckford, Chief Executive Officer of RUA GOLD. "The deposit continues to exceed our expectations and remains open in all directions. Our improved understanding of the orientation of the high-grade mineralized shoots will be crucial as we advance the next phase of drilling. The occurrence of visible gold is particularly encouraging and suggests that grades may improve with depth."
The timing is what connects this to the antimony backdrop. The 19,600 metre program was designed to improve resource confidence and to generate the geotechnical, hydrological and metallurgical data required for a pre-feasibility study, which in turn supports the Company's application under New Zealand's Fast-Track Approvals regime. Auld Creek was accepted as a listed project under that regime in July 2026, and the Company says it remains on track to submit its substantive application in October 2026 and publish the PFS in December 2026. Four rigs are to continue drilling through the fourth quarter, testing the deposit along strike and at depth.
RUA GOLD is the dominant landholder in the Reefton Goldfield with more than 120,000 hectares of permits, in a district the Company's technical report records as having historically produced over 2 million ounces of gold at grades of 9 to 50 grams per tonne. Its second project, Glamorgan, sits in the Hauraki District on the North Island, a region that has produced 15 million ounces of gold and 60 million ounces of silver. The Company also announced the appointment of Darren Prins as Interim Chief Financial Officer and Corporate Secretary. Filings are available on SEDAR+.
There are several risks associated with the Company's plans.
RUA GOLD is an exploration-stage company with no mineral reserves defined at Auld Creek and no production or revenue. Historical district production figures describe the Reefton Goldfield generally and are not indicative of what may be recovered from the Company's permits. Reported drill intercepts are selective results and are not necessarily representative of the deposit as a whole; the reported intervals are downhole widths and true widths are not known. Acceptance as a listed project under the Fast-Track Approvals regime does not guarantee that a mining permit will be granted, or granted on the timeline indicated, and the October application and December pre-feasibility study dates are the Company's stated targets rather than commitments. Advancing a project of this kind is capital intensive and may require financing that has not been secured, which could dilute existing holders. Antimony prices have been volatile and fell materially through 2026 after their post-export-control spike.
Across the rest of the antimony supply chain, the same clock is producing very different strategies:
Perpetua Resources Corp. (Nasdaq: PPTA) is developing the Stibnite Gold Project in Idaho, a gold deposit carrying antimony credits whose value is being unlocked by permitting rather than discovery. Stibnite is positioned to host the only domestic reserve of antimony in the United States.
On May 21, 2026 the Board of the U.S. Export-Import Bank unanimously approved a US$2.9 billion senior secured long-term loan for the project under EXIM's Make More in America Initiative, structured as a 13-year facility. President and Chief Executive Officer Jon Cherry described the loan as positioning the company to bring Stibnite to life and as a signal of a new day in American mineral independence. An updated Technical Report Summary published in March 2026 showed an after-tax net present value at a 5% discount rate of US$3.5 billion at a US$3,250 per ounce gold price, rising to US$6.1 billion at US$4,500 per ounce.
The instructive part for anyone reading the sector is what those numbers do not remove. Even the largest American antimony name in the public market, with nearly three billion dollars of federal lending behind it, still has years of permitting, financing and construction ahead of it before antimony is delivered to a customer. That is the timeline the whole category is working against.
