American Antimony

What American Antimony does

American Antimony Corporation (operating as Xtra Energy Corp., OTC: XTPT) is a U.S.-based critical minerals exploration and development company focused on establishing domestic antimony supply to reduce U.S. reliance on foreign sources, primarily China. The company controls approximately 4,153 acres (201 claims) in the historic Bernice Canyon antimony district of Churchill County, Nevada, encompassing the Antimony King, Arrance, King Solomon, and IHX mines, and expanded its footprint in July 2025 with the 1,240-acre Stibium Creek Project acquisition in Lander County. Headquartered in Austin, Texas, the company is publicly listed on OTC Markets with approximately 219 million shares outstanding and a market capitalization of approximately $60 million as of June 2026, supported by 1-10 employees and a leadership team led by CEO & Chairman Mac J. Shahsavar, President Dan Paulsen, and EVP Engineering Aarya Shahsavar (appointed August 2025).

The company's core technology is conventional flotation processing for antimony ore concentration. Metallurgical testing by ALS Metallurgy on Antimony King Mine bulk samples produced 63% Sb concentrate at 97% recovery from 30.3% Sb head-grade material, with grades materially above the 5-10% Sb industry norm. Phase 1 reverse circulation drilling completed in 2025 confirmed a world-class 87-meter (285 ft) continuous mineralized intercept grading 1.46% Sb (up to 5.59% Sb) with exceptionally low arsenic (<50 ppm) within a minimum 3.2 km felsite dike corridor. The company has identified approximately 20,000 tonnes of near-term exploitable surface stockpiled material.

American Antimony is pre-revenue and pursuing a sales-led go-to-market motion focused on near-term commercial sales of stockpiled material to metallurgical processors and end-users. Distribution is through direct sales relationships, anchored by a Metallurgical Testing Agreement (December 2025) with Silver Opportunity Partners LLC, a subsidiary of Sunshine Silver Mining & Refining Company, for processing validation and potential large-scale offtake. Revenue is expected to come from direct sales of high-grade antimony ore and concentrates to defense, semiconductor, energy storage, and industrial end-markets, with the Small Mine Permit process initiated in April 2026 to enable a limited five-acre operational footprint at the Antimony King Mine.

Core offering

American Antimony Corporation (operating as Xtra Energy Corp.) is a critical minerals exploration and development company advancing its flagship American Antimony Project in Nevada's Bernice Canyon district. It produces high-grade antimony ore and concentrates (63% Sb at 97% recovery) targeting domestic U.S. defense, energy storage, and industrial supply chains.

Product overview

American Antimony Corporation (operating as Xtra Energy Corporation) operates as a critical minerals mining and development company with two primary asset categories: the flagship American Antimony Project in Bernice Canyon, Nevada (4,153 acres, 201 claims) which is advancing toward domestic antimony production, and the Stibium Creek Project (1,240 acres) as a secondary exploration asset. The company produces high-grade antimony concentrates (63% Sb at 97% recovery) from its Nevada operations, targeting the U.S. defense, semiconductors, energy storage, and industrial sectors. The company is not currently in commercial production but is advancing through staged development including exploration drilling, metallurgical testing, and permitting activities.

Direct peers

• Perpetua Resources: Developer of the Stibnite Gold Project in Idaho, which contains a large antimony byproduct stream alongside gold. Directly competes for U.S. federal critical-minerals support and antimony offtake with a more advanced permitting/financing position, making it the closest strategic peer for North American antimony supply.
• Mandalay Resources: Mid-tier miner with the Costerfield mine in Australia, one of the world's largest antimony-producing operations alongside gold. Comparable antimony-gold mining profile, providing a relevant benchmark on antimony mine economics, processing flowsheet design, and antimony-byproduct valuation.
• United States Antimony Corporation: The only listed pure-play U.S. antimony producer, currently mining and processing antimony at operations in Montana/Mexico. Directly comparable as a U.S.-focused antimony miner; American Antimony is following a similar commercialization path with higher-grade ore but is earlier-stage and pre-revenue.

Emerging players

• Trilogy Metals: Junior developer of the Upper Kobuk Mineral Projects in Alaska (Ambler Mining District) with copper-zinc-lead-silver-gold-antimony mineralogy. Comparable as a small-cap critical-minerals developer seeking federal and permitting support for U.S. domestic supply.
• Sunshine Silver Mining & Refining Company: Parent of Silver Opportunity Partners and operator/developer of the Sunshine Mine in Idaho, a major domestic silver-antimony refining complex. Both a partner to American Antimony (via the MTA) and a potential downstream competitor/acquirer if domestic antimony concentrate processing consolidates.
• Idaho Strategic Minerals (formerly Idaho Champion)/Other U.S. antimony juniors: U.S.-listed junior explorers with antimony exposure seeking similar critical-mineral positioning. Comparable stage, regulatory pathway, and end-market exposure; competitive for capital, permits, and offtake contracts in the emerging U.S. antimony sector.

Others

• Boise Cascade / U.S. antimony refining capacity operators: Downstream customers and infrastructure operators in the U.S. antimony/flame-retardant supply chain. Relevant as buyers of American Antimony's concentrate and as reference points for the eventual expansion of U.S. processing capacity.

Regional players

• Lake Resources / Middle Island Resources (Australian antimony exposure): Australian-listed junior with historical antimony mining exposure (Hillgrove gold-antimony project). Comparable antimony metallurgy and mine-planning benchmarks, although based in Australia and not a direct competitor for U.S. contracts.
