U.S. Antimony Files 8-K With Nolan Creek Technical Report

U.S. Antimony Corporation (USAC) disclosed a technical report summary in a Form 8-K filing, providing an initial assessment and estimation of placer gold and lode antimony-gold resources at its Nolan Creek property in the Wiseman Mining District, Alaska. The document, titled "Initial Assessment and Estimation of Placer Gold and Lode Antimony-Gold Resources," was submitted to the company's headquarters in Dallas, Texas. Pacific Rim Geological Consulting, Inc., based in Fairbanks, Alaska, prepared the report and submitted it on October 2, 2026. The filing serves as Exhibit 99.1 to the Form 8-K, fulfilling regulatory requirements for disclosing material technical information to investors.

The technical report covers a comprehensive range of geological, engineering, and economic topics related to the Nolan Creek area. It includes detailed sections on property description and ownership, geology and mineralization, and the current status of exploration activities. The document outlines the development and operations history, as well as specific estimates for mineral resources and reserves. Mining methods, processing and recovery techniques, and capital and operating costs are also detailed within the report. An economic analysis is provided to assess the viability of the project, alongside discussions on infrastructure requirements and permitting needs. The report concludes with the qualified person's conclusions and recommendations regarding the project's future development.

The property description section identifies thirty-six federal claims purchased by USAC in January 2026 and forty-eight Alaska State Claims covering the Nolan Creek area in 2026. Accessibility to the property is described through topography and land description, with specific references to access features shown in location maps. The climate description includes vegetation and land use data, while infrastructure availability is assessed for required operations. The historical section reviews the mining history of the area, including drilling exploration summaries and historical production data from previous operations between 2005 and 2007.

Geological setting and mineralization are analyzed through regional geology, local property geology, alteration patterns, and deposit types. Exploration efforts are detailed for both heavy mineral placer deposits and lode antimony-gold deposits. Sample preparation, analysis, and security protocols are documented, including site sampling methods, laboratory procedures, and quality control programs. The qualified person provides an opinion regarding these analytical procedures. Data verification processes for exploration and mineral resource data are outlined, noting specific data limitations.

Mineral processing and metallurgical testing results are presented for both placer and lode deposits, including trace element content analysis of Nolan mineralization. Recovery estimates are provided based on these tests. Mineral resource estimates are categorized into measured, indicated, and inferred categories for lode antimony-gold resources at Nolan Creek. The report includes a discussion on mineral resource uncertainty and assumptions for multi-commodity estimates. The qualified person offers opinions on factors influencing economic extraction.

Further sections address mining methods, processing and recovery methods, and infrastructure status, including previous production infrastructure on the property. Market studies and environmental studies are reviewed, covering geotechnical-environmental studies, hydrological studies, environmental monitoring, water management plans, mine closure procedures, and permitting requirements. Plans, negotiations, or agreements with local individuals or groups are described, including commitments to ensure local hiring. Capital and operating costs are estimated, followed by an economic analysis. Adjacent properties are discussed in the context of other relevant data and information.

The interpretation and conclusions section summarizes findings on mineral resources, environmental permitting and social issues, mineral processing, and mineral reserves. Recommendations are provided for mineral resources, environmental permitting and social aspects, geotechnical considerations, mineral processing, tailings storage facilities, and mineral reserves. The report concludes with references and a statement on reliance on information provided by the registrant. Appendices contain additional supporting data.
