VANCOUVER – USA News Group News Commentary – Western defense stockpiles face a critical shortage as Pentagon spending surges past $1 billion to rebuild antimony reserves following Chinese export restrictions that slashed shipments by 97%[1]. Antimony prices have climbed above $40,000 per ton as governments scramble to secure this defense-critical metal essential for ammunition, night vision systems, and nuclear weapons[2]. This supply crisis has elevated Western antimony developers to strategic national security assets, spotlighting companies positioned to capitalize on unprecedented government support like RUA GOLD Inc. (TSXV: RUA) (OTCQB: NZAUF), Nova Minerals Limited (NASDAQ: NVA), Americas Gold and Silver Corporation (NYSE-American: USAS) (TSX: USA), Maxum Mining Inc. (CSE: MAXM), and Perpetua Resources Corp. (NASDAQ: PPTA) (TSX: PPTA).

Market analysts project the global antimony market will expand from $2.15 billion in 2025 to $3.17 billion by 2035, driven by defense stockpiling and battery applications[3]. With Montana's only operating antimony smelter expanding capacity 400%[4] and multi-million dollar government contracts flowing to domestic producers, Western antimony miners are capturing strategic value as supply chain security trumps traditional commodity economics.

RUA GOLD Inc. (TSXV: RUA) (OTCQB: NZAUF) is positioning itself as a critical player in Western antimony supply at a pivotal moment for global mineral security. As China tightens export controls on approximately 60% of the world's antimony production, and New Zealand formally designates the metal as critical, the company's gold-antimony projects in the historic Reefton Goldfield are drawing heightened institutional interest.

The company's recent drilling at Auld Creek delivered exceptional intercepts, including 17m at 9.8g/t AuEq (3.6g/t Au & 1.5% Sb) and 8m at 8.9g/t AuEq (6.2g/t Au & 0.6% Sb), significantly expanding the mineralized system. The September results extended the deposit vertically from 160m to over 300m depth and along strike from 350m to 620m. Surface samples have yielded over 40% antimony, while multiple drill holes exceed 8% Sb—grades uncommonly encountered at this exploration stage.

"These drill results from Auld Creek have significantly expanded the scale and potential of the project and put us well on the way to growing the resource base as we announced last month," said Robert Eckford, CEO of RUA GOLD. "Importantly, the mineralized system has been extended both vertically and along strike and remains open in all directions."

RUA GOLD recently announced a major program expansion, deploying a third rig to drill over 4,000 metres at Auld Creek with the goal of pushing the antimony resource above 15,000 tonnes by year-end (valued at US$600 million using a $40,000/t antimony price). A third rig is also testing high-priority regional targets identified through the company's VRIFY AI targeting process. Regional exploration has already uncovered promising mineralization, with rock chip samples at the Bell Hill permit—30km south of Reefton—grading 14.3g/t gold. The strike length of the known mineralisation in Reefton is over 60 kilometers.

The antimony component carries strategic weight beyond typical exploration economics. This defense-critical metal is essential for ammunition, flame retardants, and advanced battery applications. New Zealand's critical mineral designation for antimony positions RUA GOLD's assets within a national security framework that could expedite permitting and development pathways as Western nations seek supply alternatives.

Throughout October, management completed an extensive investor roadshow spanning six conferences across three continents, including the Munich Mining Conference, Metals & Mining Virtual Investor Conference, Hidden Gems Conference in New York, the International Mining and Resources Conference in Sydney, the West Coast Minerals Forum in New Zealand, and the Swiss Mining Institute Conference in Zurich.

"We're excited to showcase RUA GOLD on this global stage and connect with some of the top minds in mining investment," said Eckford. "With antimony supply tightening and gold reaching further record highs, RUA GOLD is positioned to be the next explorer transitioning to developer in New Zealand."

The Reefton Goldfield historically produced over 2 million ounces of gold at grades reaching 50 g/t up to the 1940’s. They also pulled up antimony but left it on surface as they didn’t have the know how to process it back then. RUA GOLD now controls approximately 95% of the district—120,000 hectares—and has confirmed stacked mineralized shoots at Auld Creek. Two rigs are actively drilling the Bonanza shoot in the north and Fraternal shoot in the south, with surface geochemistry confirming a 2.5km strike length.

On the North Island, drill permits have been submitted for the Glamorgan project in the Hauraki Goldfield, which neighbors the 10 Moz Martha mine. The project's 4km gold-arsenic anomaly has been refined using VRIFY's DORA AI engine, with Q4 drilling expected.

With $14 million in treasury and a leadership team behind US$11 billion in past mining exits, RUA GOLD is funded to advance discovery growth across both islands. The dual-commodity profile—combining high-grade gold potential with strategic antimony exposure—creates a compelling value proposition as both metals command premium investor attention globally.

In other industry developments and happenings in the market include:

Perpetua Resources Corp. (NASDAQ: PPTA) (TSX: PPTA) has broken ground on early works construction at its Stibnite Gold Project in Idaho after posting $139 million in financial assurance and receiving formal construction approval from the U.S. Forest Service. The project hosts America's only reserve of the critical mineral antimony and represents the nation's direct response to China's export restrictions on this defense-critical material.

"Today, we break ground on the Stibnite Gold Project," said Jon Cherry, President and CEO of Perpetua Resources. "As America's answer to China's antimony export bans, we are focused on swiftly and safely bringing our antimony and gold project into development. After nine years of permitting, Stibnite can once again serve this country's national interest."

The project anticipates more than 950 direct jobs during construction and 550+ during operations, with approximately 450,000 ounces of annual gold production over its first four years alongside strategic antimony output. Perpetua has received a preliminary project letter and indicative term sheet from the U.S. Export Import Bank for $2 billion in debt financing, with final board consideration expected by spring 2026.

Americas Gold and Silver Corporation (NYSE-American: USAS) (TSX: USA) has announced antimony production results for the first time under new management, reporting 447,466 pounds of antimony and 615,817 pounds of copper produced during the first three quarters of 2025 from its Galena Complex—the only currently producing antimony mine in the United States. The operation maintains a consistent antimony-to-copper ratio of approximately 0.73:1 from its high-grade silver tetrahedrite ore, which serves as the primary host for both critical metals.

"Highlighting Galena as the only producing antimony mine in the United States, I am thrilled to announce both antimony and copper production from our Galena Complex," said Paul Andre Huet, Chairman and CEO of Americas Gold and Silver. "With our recently announced breakthrough of 99%+ antimony extraction from flotation concentrate grading approximately 19% antimony, and the potential to realize on commercial recovery and marketable antimony products that can be produced using proven metallurgical processes, we are in a very strong position to be a major supplier of critical metals that the United States needs."

The antimony production has been delivered while the company makes investments into several growth projects at Galena to scale silver production materially by several multiples, with concurrent increases in antimony output expected as the company focuses on increasing production of high-grade silver tetrahedrite ore. Quarterly production showed strong consistency with Q2 2025 delivering 173,393 pounds of antimony alongside 239,949 pounds of copper.

Nova Minerals Limited (NASDAQ: NVA) has commenced procurement of critical mining and processing equipment for its Estelle starter antimony operations in Alaska, targeting first production of military-grade antimony trisulfide by 2026/27 with support from a US$43.4 million U.S. Department of War award. Equipment purchases include mining fleet, crusher and screening plant, and two ore sorters following successful test work that achieved 60.3% antimony recovery in a single pass, upgrading feed grade from 15.2% to 35.2% antimony—a 2.3-fold improvement.

"Nova is rapidly progressing to become a fully-integrated domestic producer of military-grade antimony," said Christopher Gerteisen, CEO of Nova Minerals. "Fuelled by a non-dilutive US$43.4 million award from the U.S. Department of War, we are currently procuring mining and processing equipment expected for delivery in January 2026. Bolstered by Port Mac district commercial industrial-zoned land, unwavering federal, state and local government support, and surging demand from partners offering us further feedstock, we believe that Nova is well positioned to be a leader as one of the nation's antimony producers."

The company maintains access to approximately A$83.0 million in funding comprising A$17.5 million in cash and the DoW award, providing a robust foundation to advance its strategic antimony and gold development programs. One ore sorter will be installed at the Whiskey Bravo camp to process stibnite ore stockpiled during the current field season, with the second ore sorter located at the proposed Port MacKenzie refinery site to potentially upgrade feedstock from other prospective antimony offtake sources currently under discussion.

Maxus Mining Inc. (CSE: MAXM) (FRA: R7V) has highlighted high-grade antimony potential at its Alturas West Project in British Columbia, where the historic Alps-Alturas Mine shipped approximately 95 tonnes of high-grade antimony-bearing material averaging 57.2% antimony, including 24.5 tonnes grading 50-60% antimony. Recent historical grab samples confirmed exceptional grades including 69.98% antimony, 67.96% antimony, and 49.98% antimony, while historic surface rock chip sampling in 1990 outlined a 1.7-kilometre antimony trend along the major shear zone with samples exceeding 1,000 ppm antimony.

"The identification of a 1.7-kilometre antimony trend through historic sampling marks an important milestone for our team," said Scott Walters, CEO of Maxus Mining. "This discovery positions the Project as a compelling opportunity within Canada's growing critical minerals landscape, and we look forward to advancing exploration to define the full scope of this mineralized system."

The 899-hectare property is road accessible and strategically located in the historically significant Slocan Mining Division north of the past-producing Silvana Mine, with surface samples returning over 40% antimony and several drill holes exceeding 8% antimony—grades rarely seen this early in a project's development cycle. The Alturas West Block covers more than two kilometres of a significant east-west trending reactivated shear zone hosting disseminated pyrite and argentiferous tetrahedrite with minor stibnite and chalcopyrite, with Equinox Resources recently discovering massive stibnite in quartz veins along this largely untested structural trend.
