Resolution Minerals (ASX:RML) Eyes Nasdaq as US Antimony Demand Surges: Time to Buy?

Resolution Minerals: Nasdaq bid and antimony upside

Resolution Minerals (ASX: RML) is making a bold play for US investors, filing a registration statement with the SEC as the first step toward a Nasdaq dual listing. The company has also set up a Level 1 ADR facility on the OTCQB market, allowing American investors to buy shares in US dollars. For a small-cap explorer, this is an ambitious move. But with antimony prices soaring and the US scrambling to secure domestic supply, the timing could hardly be better.

The key question for investors is whether Resolution Minerals can deliver on its promise or whether this remains a high-risk punt on exploration success.

Why Nasdaq and Why Now

The strategic backdrop here is crucial. The United States has not mined any antimony since 2001, leaving it almost entirely dependent on imports for minerals essential to ammunition, night vision goggles, and flame retardants. China controls nearly half of global antimony mine production and has implemented a restrictive export licensing system for 2026-2027, with only 11 companies permitted to export antimony and 15 for tungsten, sending prices for both metals to record highs.

This supply crisis has created a rush for domestic antimony projects. Resolution’s Horse Heaven project sits directly next to Perpetua Resources’ Stibnite Gold Project, a development that has attracted US$1.8 billion in potential financing from the US Export-Import Bank. Perpetua now carries a market cap of approximately US$3.4 billion.

We believe a Nasdaq listing could significantly raise Resolution’s profile with US institutions and potentially unlock access to government funding programs. The company has engaged Washington-based advisers to pursue the FAST-41 designation, the federal program that streamlines permitting for critical minerals projects. Perpetua’s Stibnite was the first mining development accepted under FAST-41, and Resolution hopes to follow suit.

The Horse Heaven Project Shows Exceptional Grades

Resolution’s flagship Horse Heaven project covers over 5,644 hectares in Idaho, just 6 to 12 kilometres from Perpetua’s Stibnite deposit. The project hosts past-producing antimony, tungsten and gold mines, including the Golden Gate Tungsten Mine, which operated from the 1950s through 1980. Recent surface sampling at the Antimony Ridge target has returned grades that are genuinely eye-catching.

Peak results from the Antimony Ridge target include grab samples assaying up to 48.7% antimony and 890 grams per tonne silver. For context, the largest antimony mine in China typically operates below 10% grade, and a nearby Idaho mine reports grades under 0.5%. Finding material with nearly 50% antimony exposed at the surface is rare anywhere in the world.

The company has also made a gold discovery at the Golden Gate North prospect, with Phase 2 drilling now funded following the AUD 2.2 million sale of its non-core 64North project in Alaska. Resolution Minerals has appointed a veteran geologist who worked at the Golden Gate Tungsten Mine during its last production period to accelerate tungsten exploration, with drilling planned for June 2026. Metallurgical testing is underway at the Antimony Ridge target, a critical step towards understanding whether these grades can be commercially processed.

The Investor’s Takeaway for Resolution Minerals

Resolution Minerals remains a pre-revenue explorer, which means this is a speculative opportunity suitable only for risk-tolerant investors. There is no resource estimate yet, no feasibility study, and the company will need continued exploration success and capital raises to advance toward production.

However, several factors make this worth watching. The exceptional surface grades suggest the potential for high-grade direct shipping ore. The proximity to Perpetua could provide infrastructure advantages and geological validation. And a successful Nasdaq listing could drive a re-rating as US investors gain easier access.

For those comfortable with early-stage exploration risk, we believe Resolution offers an interesting way to gain exposure to the US antimony and tungsten thematic at a fraction of Perpetua’s valuation. Watch for drilling results, FAST-41 progress and the Nasdaq listing as key catalysts.
