NEW YORK, Dec. 08, 2025 (GLOBE NEWSWIRE) -- While China still controls approximately 60% of global antimony production, other countries are expanding their market shares through strategic investments. Recent trade policies and sustainability concerns are accelerating this diversification. One recent report by IntelMarket Research said that: "The global antimony mineral market is experiencing significant growth, fueled by rising demand from flame retardant applications. With increasing fire safety regulations across industries such as construction, automotive, and electronics, antimony trioxide remains a critical component in halogenated flame retardants. While the compound accounts for approximately 65% of total antimony consumption globally, manufacturers are investing in advanced production techniques to meet stringent environmental standards without compromising performance. Recent developments in nanoparticle formulations are enhancing flame retardant efficiency while reducing overall material usage, creating new opportunities for market expansion amid growing sustainability concerns. The renewable energy transition is reshaping antimony demand patterns, particularly in lead-acid battery applications. While lithium-ion dominates electric vehicle markets, antinomial lead alloys continue playing a vital role in starter batteries and energy storage systems, constituting nearly 20% of global consumption. Emerging research into antimony-based anode materials for next-generation batteries could potentially unlock new high-value applications, though commercial viability remains limited by current technological constraints. Market participants are closely monitoring these developments while optimizing traditional battery-grade antimony production." Active Companies in the mining industry this week include Xtra Energy Corporation (OTCID: XTPT), United States Antimony Corporation (NYSE:UAMY), Perpetua Resources Corp. (NASDAQ:PPTA) (TSX:PPTA), Lithium Americas Corp. (NYSE:LAC) (TSX:LAC), MP Materials Corp. (NYSE:MP).

IntelMarket Research continued: "Geopolitical factors are prompting significant shifts in antimony supply chains, with China's dominant position facing challenges from emerging production hubs. While China still controls approximately 60% of global antimony production, countries like Tajikistan, Russia, and Australia are expanding their market shares through strategic investments. Recent trade policies and sustainability concerns are accelerating this diversification, with downstream manufacturers increasingly seeking traceable and ethically sourced materials. Environmental regulations in major producing regions are also driving technological upgrades, with cleaner processing methods becoming economically viable as carbon pricing mechanisms mature globally. Asia-Pacific dominates the global antimony mineral market, accounting for over 60% of global demand as of 2024. China stands as the epicenter of production and consumption, leveraging extensive domestic reserves and serving as the primary supplier to downstream industries. The region benefits from a robust manufacturing ecosystem for flame retardants, lead-acid batteries, and ceramics key applications driving antimony demand. While China leads in output, India and Southeast Asia are emerging as growth markets due to rapid industrialization, though they remain heavily reliant on imports."

American Antimony Corp. Signs Metallurgical Testing Agreement with Silver Opportunity Partners LLC, a Subsidiary of Sunshine Silver Mining & Refining Company (SSMRC) - American Antimony Corporation, operating as Xtra Energy Corporation (OTCID: XTPT), a U.S.-based mineral development company focused on domestic antimony resources, and Silver Opportunity Partners LLC, a subsidiary of Sunshine Silver Mining & Refining Company (SSMRC), are pleased to announce they have entered into a formal Metallurgical Testing Agreement (MTA) to evaluate antimony-bearing material from American Antimony's American Antimony Project, located in Bernice Canyon, Nevada.

Through the agreement, American Antimony will supply test shipments of high-grade antimony ore for evaluation under the terms outlined in a Scope of Work, which governs the sampling, testing, and analysis procedures. Under the Scope of Work, Silver Opportunity Partners will conduct a series of metallurgical tests designed to:

• Estimate antimony recoveries;
• Identify potential penalty or deleterious elements;
• Assess reagent consumption and processing compatibility; and
• Determine the overall suitability of the material for integration into the existing Sunshine Silver flowsheet.
  
  

Initial testwork will be performed through third-party laboratories in coordination with Silver Opportunity Partners and SSMRC's technical team. If results indicate compatibility, the parties may elect to expand the testing program under mutually agreed terms to confirm full-scale processing suitability.

"This agreement represents another important step in developing a fully integrated, American-controlled supply chain for antimony," said Mac J. Shahsavar, P.Eng., CEO of American Antimony Corp. "We're proud to collaborate with a respected domestic partner like Sunshine Silver. This work will not only help validate the processing characteristics of our Nevada-sourced material but also advance the broader goal of establishing U.S. refining capability for this critical mineral."

Both companies note that antimony—a federally designated critical mineral—is vital for defense systems, semiconductors, energy storage, and flame-retardant materials. With global supply dominated by China and limited domestic production, developing secure U.S.-based sources and refining capacity remains a top priority for industry and national policy leaders.
