AUSTIN, TX / ACCESS Newswire / January 21, 2026 / American Antimony Corporation (OTCID:XTPT), operating as Xtra Energy Corporation, in collaboration with Western Frontier Exploration & Mining, an exploration-to-production mining contractor, is pleased to announce the successful completion of a comprehensive field site visit across the Company's flagship Nevada antimony asset. The visit included advanced drone surveys and the commencement of detailed operational planning aimed at establishing long-term, consistent domestic antimony supply.

Western Frontier has extensive experience in the rehabilitation and modernization of historical mines, technical mine planning, engineering, portal collaring, ramp development, bulk sampling programs, and full-scale mine production. American Antimony Corp. is currently engaged in discussions with Western Frontier regarding the potential revival of its flagship Nevada antimony project.

Management and technical teams from American Antimony and Western Frontier Exploration & Mining conducted on-site inspections across multiple historic and active targets within the district, including Antimony King, King Solomon, Arrance, IHX, and surrounding prospects. The visit focused on validating historical workings as production targets, collecting ore for testing, mapping surface expressions of mineralization, confirming access routes, and identifying priority development areas.

As part of this initiative, Western Frontier deployed advanced drone photogrammetry to capture high-resolution terrain models across the project area. The data is currently being processed into detailed 3D topographic surfaces to:

• Quantify historical stockpiles and waste dumps
• Identify structural controls and vein orientations
• Optimize future drill targeting
• Support mine planning and permitting strategies
• Improve logistics planning and communication with government agencies

Operational Planning & Supply Strategy

Following the successful delivery of the Company's 400 kg super sack of high-grade antimony ore under its recent MTA agreement, American Antimony Corporation has now entered the next phase: scalable operations planning.

Current workstreams may include:

• Mine access and drift rehabilitation planning
• Stockpile characterization & bulk sampling
• Equipment logistics & staging
• Production sequencing models
• Long-term supply consistency frameworks
• Metallurgical optimization pathways

The objective is to transition from exploration success to repeatable, domestic antimony production - addressing the United States' estimated 75%+ supply deficit for this critical defense metal.

Strategic Importance

Antimony remains classified as a critical mineral by the U.S. government, essential to:

• Defense systems
• Flame retardants
• Semiconductors
• Battery technology
• Advanced alloys

American Antimony is positioning itself to become one of the only domestic producers capable of supplying U.S. markets with secure, exclusively U.S.-sourced antimony.

Management Commentary

"This marks another major point of progress for American Antimony. We've moved from proving the mineral system through drilling to executing real-world logistics - including ore shipments and now detailed mine planning," said Mac J. Shahsavar, P.Eng., Chief Executive Officer of American Antimony Corp.

"Western Frontier's drone program provides unprecedented visibility across our assets. We are now building a clear roadmap toward sustainable production. Our goal is simple: deliver consistent, high-grade American antimony supply."

"Sean-Rae Zalewski, in his advisory capacity to XTPT and in the spirit of collaboration with Sidney Resources Corporation, as Chief Executive Officer, supported this initiative as part of a collaborative effort to advance operational planning and strengthen domestic antimony supply," said management.

As previously disclosed, Mr. Zalewski's collaboration with XTPT was referenced in the Company's January 2025 press release announcing the retention of strategic support from Sidney Resources Corporation following its $8 million financing.
