In December 2024, Americas consolidated full ownership of the Galena Complex, increasing its stake from 60% to 100% in a transaction with Eric Sprott, who remains the company's largest shareholder with an approximate 20% interest. Led by Chairman and CEO Paul Huet, Americas maintains a fully funded balance sheet to execute its growth strategy focused on becoming a leading North American silver and antimony producer.

The company's engagement with Lot Sixteen represents a strategic initiative to advance domestic antimony production capabilities at a time when supply chain security for critical minerals has emerged as a national priority. For investors evaluating Americas Gold and Silver, the combination of existing production capacity, government engagement through experienced advisors, and the strategic importance of antimony positions the company as a potential beneficiary of federal support for domestic critical minerals development.

Strategic Government Relations Partnership

Americas Gold and Silver has formalized an agreement with Lot Sixteen LLC to support engagement with federal government agencies regarding antimony production and processing capabilities. Lot Sixteen brings specialized expertise in advancing domestic critical minerals projects, providing counsel on natural resource policy matters, and securing federal funding for clients operating in the mining and energy sectors.

The consultancy will support Americas' efforts to advance antimony processing infrastructure development in Idaho's Silver Valley. This engagement strategy reflects the company's recognition that government support may prove instrumental in developing domestic processing capabilities for antimony, which maintains status as a federally-recognized critical mineral.

The timing of this partnership aligns with broader federal initiatives focused on reducing dependence on foreign sources for minerals deemed critical to national security and economic competitiveness. Antimony's applications span defense manufacturing, energy storage systems, and industrial production, creating multiple stakeholder constituencies with interest in secure domestic supply.

Galena Mine Complex: Current Production & Historical Context

The Galena mine complex operates in Idaho's Silver Valley, a historic mining district that has produced metals for over a century. Americas currently extracts silver-lead-copper-antimony concentrate from the 100%-owned facility. The site holds the distinction of being the only producing antimony mine in the United States, a position that provides Americas with unique leverage in discussions regarding domestic critical minerals supply.

Production of antimony at Galena extends back more than eight decades, with the mine having produced antimony continuously since the 1940s. This operational track record differentiates Americas from potential competitors or new entrants that would need to establish production from greenfield projects.

Paul Andre Huet, Chairman and CEO, stated:

"Americas Gold and Silver's Galena Mine in Idaho is already the sole and largest antimony producer in the United States. Our Galena mine has been producing significant amounts of antimony since the 1940's, and our test work this year has clearly reconfirmed the viability of extracting saleable antimony products from tetrahedrite concentrates currently produced."

The company's recent metallurgical testing has validated the technical feasibility of extracting marketable antimony products from the tetrahedrite concentrates generated through current operations. This confirmation supports the technical foundation for potential expansion of antimony processing capabilities at the site.

Proposed Antimony Processing Facility

Americas is evaluating the construction of a dedicated antimony processing plant in Idaho's Silver Valley. The proposed facility would process concentrate from the Galena mine's current production operations. The company has indicated that subject to capacity considerations, the plant could potentially accept feedstock from additional sources beyond Galena's own production.

This approach would position the facility as a potential regional hub for antimony processing, aggregating material from multiple sources to achieve economies of scale. The hub concept could provide processing services for other antimony-bearing materials that currently lack domestic processing options.

The design phase for the proposed processing facility is currently underway. Technical specifications, capital requirements, and timeline projections for the facility have not been disclosed in the company's announcement. The feasibility and ultimate construction of the facility may depend on factors including technical validation, economic analysis, permitting requirements, and potential government support mechanisms.

Huet commented:

"We are currently underway with the design of a new antimony processing facility for our Galena concentrate and are very pleased to engage Lot Sixteen to assist in our ongoing discussions with the United States Government. With the strong support of government and industry stakeholders, we believe Idaho can become the centerpiece of a resilient domestic supply chain for this critical metal."

Antimony's Critical Mineral Status & Applications

Antimony maintains designation as a federally-recognized critical mineral, reflecting government assessment of its importance to economic and national security combined with supply chain vulnerability. The metal serves multiple industrial applications that underpin this strategic classification.

Defense sector applications represent a significant demand driver for antimony. The metal is used in ammunition production, night vision equipment, infrared sensors, and various munitions systems. These defense applications create a direct national security dimension to antimony supply availability.

Energy sector uses include flame retardants, batteries, and solar panel production. The expansion of energy storage systems and renewable energy infrastructure has increased industrial demand for antimony-containing materials. Manufacturing applications span a broad range of industrial processes including specialty alloys, semiconductors, and various chemical compounds.

Current U.S. antimony supply relies heavily on imports, with China representing the dominant global producer and processor. This concentration of supply in a single nation creates supply chain risk that has attracted attention from policymakers focused on critical minerals security. Americas' position as the only domestic producer provides potential leverage in accessing federal programs designed to support critical minerals development.

Ownership Structure & Financial Position

Americas' ownership consolidation of the Galena Complex in December 2024 simplified the corporate structure and provided full control over the strategic asset. The transaction increased the company's stake from 60% to 100% through an agreement with Eric Sprott, a prominent mining investor who continues to hold approximately 20% of Americas' outstanding shares.

This ownership structure aligns the interests of Americas' largest shareholder with the company's strategic direction on antimony development. Sprott's continued significant stake following the transaction may signal confidence in the company's growth trajectory and the value potential of the Galena asset.

Americas has indicated it maintains full funding to execute its growth plans. The company has not specified whether this funding position contemplates the full capital requirements for constructing the proposed antimony processing facility or whether additional capital would be required. Potential government support mechanisms could affect the company's capital requirements for the processing facility project.

Market Context & Competitive Position

Americas' status as the sole producing antimony mine in the United States provides a first-mover advantage in domestic supply development. No other U.S.-based antimony projects are currently in production, though several exploration and development projects exist at various stages of advancement.

The lack of domestic antimony processing capacity means that even Americas' current production must be shipped abroad for processing into refined products. This processing gap represents both a challenge for current operations and an opportunity if domestic processing capabilities can be established.

Global antimony markets have experienced volatility driven by supply disruptions, trade policy changes, and demand fluctuations across end-use sectors. China's dominant position in both mining and processing creates concentration risk that has prompted policy responses in consuming nations. The European Union and other jurisdictions have similarly identified antimony supply security as a strategic priority.

For Americas, the combination of existing production, processing facility development plans, and government engagement creates a differentiated positioning relative to earlier-stage antimony projects. However, the company faces execution risk in advancing the processing facility from concept through construction and commissioning.

For Investors

Americas Gold and Silver has positioned itself at the intersection of domestic critical minerals policy and operational reality through its ownership of Galena, the United States' only producing antimony mine. The engagement of Lot Sixteen to facilitate government discussions represents a proactive approach to accessing potential federal support mechanisms available for critical minerals development.

Investors evaluating Americas should consider several factors in assessing the company's antimony strategy. The existing production base provides tangible operational capacity rather than speculative development potential, differentiating Americas from earlier-stage competitors. The proposed processing facility would address a clear gap in the domestic antimony supply chain, potentially enhancing both margins and strategic value.

However, the processing facility remains in early design stages, with material uncertainties around capital requirements, timeline, government support, and ultimate economics. The company's broader business includes silver production from both Galena and Cosalá operations, providing diversification beyond antimony-specific exposure.

The critical minerals policy environment creates potential tailwinds for companies like Americas that can demonstrate domestic production and processing capabilities for strategically important metals. Whether these policy priorities translate into tangible benefits for Americas will depend on execution of the processing facility project, government support outcomes, and antimony market fundamentals. Investors focused on critical minerals exposure with existing production may find Americas' combination of current operations and development optionality relevant to portfolio positioning.
