EV Resources (ASX: EVR) doubles down on U.S. critical minerals with Milton Antimony acquisition

Why did EV Resources acquire the Milton Antimony Project in Nevada and how does it fit into its U.S. critical minerals strategy?

EV Resources Limited (ASX: EVR) has taken another decisive step in building a cross-border critical minerals business with the acquisition of the Milton Antimony Project in Nye County, Nevada. The announcement, made on September 26, 2025, positions the company at the center of U.S. efforts to secure non-Chinese supply of antimony, a mineral listed by the U.S. Department of the Interior as critical to defense, energy storage, and advanced manufacturing.

The deal expands upon EVR’s recent purchase of the Dollar Antimony Project, also located in Nevada near the Hawthorne military storage facility. Together, Milton and Dollar form a dual-asset base in one of the world’s most stable mining jurisdictions, offering the company both credibility and strategic positioning at a time when Washington is actively encouraging domestic sourcing of critical minerals.

What makes the Milton Antimony Project a high-potential acquisition for EV Resources?

The Milton Antimony Project lies on the western flank of the Shoshone Range and covers 3.6 square kilometers through 18 mapped lode claims. Historically, the project was productive, with records showing around 30 tons of ore shipped in 1939 averaging an impressive 40 percent antimony content. More recent geological assessments have identified high-grade assays from historic workings and stockpiles, including samples grading up to 20.77 percent antimony. Other workings recorded values of 12.57 percent, while U.S. Geological Survey records confirmed mineralization at levels up to 3 percent.

The project area is characterized by structurally controlled stibnite oxide mineralization hosted in Triassic limestone, with silver and gold credits present. Historic mine workings include shafts extending up to 64 meters in depth, adits, and shallow subsurface operations that demonstrate a well-developed vein system. Importantly, these mineralized veins remain open both along strike and at depth, suggesting further exploration could unlock additional resources.

This combination of high-grade historical production, credible assays, and clear geological potential makes Milton an attractive addition to EVR’s portfolio. The presence of silver and gold credits also adds optionality for future resource development.

How does the Nevada expansion complement EV Resources’ antimony assets in Mexico?

While the U.S. acquisitions strengthen EVR’s North American footprint, its flagship Los Lirios Antimony Project in Puebla, Mexico, remains central to the company’s near-term production strategy. Los Lirios has already seen progress in trenching, mapping, and metallurgical testing, with road access completed and several mineralized structures mapped. These developments provide the foundation for EVR to begin concentrate production in the near term.

The company’s plan is to link production at Los Lirios with processing and downstream development at its Nevada projects. This integrated model would allow concentrate from Mexico to flow into U.S. markets, thereby creating a fast-to-market supply chain. By structuring operations across allied jurisdictions, EVR is positioning itself as a reliable partner for the U.S. Department of Defense, Department of Energy, and downstream manufacturers seeking secure and non-Chinese antimony supply.

How much is EV Resources paying for the Milton Antimony Project and what could the deal mean for shareholder value?

EV Resources will acquire Strategic Minerals Inc., the entity that holds the 100 percent interest in Milton, from Nevada-based MineMaker LLC. The consideration involves a cash payment of AUD 150,000 due within 15 days of the agreement, a further AUD 350,000 in EVR common shares to be issued upon completion, and a two percent net smelter return royalty on all production from the project.

The royalty agreement provides the vendor with long-term upside while aligning incentives with EVR’s development success. Completion of the acquisition is contingent on the vendor finalizing legal title to the claims within 50 days. If this condition is not met, the agreement can be terminated.

For shareholders, the acquisition terms are relatively modest compared to the potential upside. The limited upfront cash component preserves EVR’s balance sheet, while the scrip and royalty elements ensure that the vendor remains invested in the project’s success.

How are investors responding to EV Resources’ growing U.S. portfolio?

The market’s immediate reaction to the Milton acquisition was positive. On September 26, EVR’s shares rose 10.71 percent to AUD 0.016, marking a new 52-week high and taking the stock’s one-year return to a staggering 238.17 percent. Trading volume surged above 20 million shares, well above the stock’s daily averages.

With a market capitalization of AUD 38.17 million and 2.46 billion shares on issue, EV Resources remains a speculative small-cap. However, investor sentiment has clearly shifted as the company builds a portfolio aligned with Western government priorities. Institutional sentiment appears cautiously optimistic, as the integration of Nevada assets alongside Mexico provides credibility and geopolitical relevance. For retail investors, the sharp rise in share price reflects enthusiasm for exposure to the antimony theme, even though execution risk remains high.

What are the key risks and regulatory challenges facing EV Resources?

Despite the high-grade assays and strong strategic rationale, risks remain. The Milton project, located within the Toiyabe National Forest, will require close coordination with the U.S. Forest Service and adherence to federal land management regulations. Any delays in permitting could impact timelines.

The company is also exposed to the risks inherent in early-stage exploration. Historic assays confirm prospectivity, but resource definition drilling is needed before economic viability can be established. Financing requirements represent another challenge, as the transition from exploration to development often demands significant capital.

Commodity price volatility is also a factor. Antimony prices, influenced by Chinese supply dominance, can fluctuate sharply. While this creates upside opportunities in tight supply conditions, it also poses risks if demand weakens or alternative supply emerges.

What are the next steps for EV Resources following the Milton acquisition?

EV Resources has outlined a multi-pronged work program. The company will begin confirmatory sampling and mapping at Milton, integrate both Nevada assets into a cohesive development strategy, and continue advancing Los Lirios toward drilling and resource definition. At the same time, EVR plans to engage with U.S. end-users and government agencies to secure offtake agreements and explore strategic funding opportunities.

This roadmap reflects the company’s ambition to evolve from an exploration player into a supplier of processed antimony concentrate to the United States and allied markets.

What does this acquisition mean for the broader critical minerals sector?

The acquisition of the Milton Antimony Project highlights a growing trend in the junior mining sector, where companies are seeking assets in Tier 1 jurisdictions aligned with Western critical minerals strategies. For EV Resources, the move underscores the importance of integrating projects across borders to provide supply security.

More broadly, the deal reflects how mid-tier and junior miners are positioning themselves in anticipation of sustained demand for critical minerals. Governments across the U.S., Europe, and Australia are emphasizing resource security, creating opportunities for companies like EVR that can align projects with policy priorities.

What are the final takeaways on EV Resources’ strategy and its future role in the global antimony supply chain?

The Milton Antimony acquisition strengthens EV Resources’ case as a small but strategically significant player in the global antimony supply chain. With assets spanning Mexico and the United States, the company has carved out a position that is not only geologically promising but also geopolitically relevant.

For investors, the stock’s sharp rise and expanding U.S. presence demonstrate momentum, but execution risk should not be ignored. The company must translate its portfolio into tangible production pathways while navigating regulatory, financial, and operational hurdles.

Nevertheless, EV Resources’ strategy of building a fast-to-market, non-Chinese antimony supply chain aligns squarely with Western policy goals. In an industry where timing and jurisdiction matter as much as grade, the company has moved early to secure projects that could prove pivotal in the years ahead.
