Why I like RML's position, my article - Mining Reform Bill Could Accelerate Resolution Minerals’ Idaho Gold and Antimony Projects

U.S. Mining Reform Bill Could Accelerate Resolution Minerals’ Idaho Gold and Antimony ProjectsWritten 16:19, 02 Dec 2025 AEDT

IDAHO / SYDNEY — Resolution Minerals (ASX:RML) appears well-positioned to benefit from sweeping U.S. mining reforms advancing through Congress, as the company continues to deliver strong results from its Horse Heaven gold–antimony district in Idaho.

The proposed legislation, H.R. 4090 — the Critical Mineral Dominance Act — aims to fast-track domestic hard-rock mining by accelerating approvals, expanding access to Federal land and prioritising developments containing strategic minerals such as antimony and tungsten. Having cleared committee review, the bill has now been placed on the Union Calendar, making it eligible for floor debate.

Both the Golden Gate discovery and the Antimony Ridge target sit on Federal ground adjacent to Perpetua Resources’ well-known Stibnite project — placing RML’s assets squarely within the category of operations the legislation seeks to encourage.

Trading Commentary - My Stance: Bullish RML has experienced one of the more dramatic moves on the ASX resources board this year. The stock climbed from near-record lows of A$0.007 in early 2025 to a high of ~A$0.15 following strong Idaho drill results and rising interest in U.S. critical-mineral projects. The current pullback into the A$0.06 range reflects normal profit-taking after a multi-hundred-percent move, combined with broader volatility across junior miners.

Price action remains highly sensitive to drilling outcomes, U.S. policy developments, and macro sentiment. With no revenue and exploration-driven cash burn, the stock trades primarily on perceived future value rather than fundamentals — making it a high-risk, high-reward play aligned with catalysts such as H.R. 4090 and further results from Golden Gate and Antimony Ridge.

Golden Gate Continues to Build Scale

Resolution Minerals recently reported one of its most significant intercepts at Golden Gate: 253 metres at 1.5 g/t gold from surface, including 111.9 metres at 2.31 g/t, confirming a broad intrusion-related gold system (IRGS) with substantial vertical and lateral continuity.

Craig Lindsay, RML’s Head of U.S. Operations, said the scale emerging at Golden Gate has exceeded early expectations.

“What you’re looking at is about eighty million tons of rock there… and that’s only covering twenty percent of the target,” he said.

Current drilling has defined a mineralised zone stretching roughly 600 metres along strike, with mineralisation extending from surface down to nearly 300 metres. This represents only a portion of the broader three-kilometre structural corridor.

Lindsay noted:

“We’ve got these very thick intercepts with mineralization starting from surface and running down almost to three hundred meters in depth.”

He added that, when viewed alongside historical data, early results indicate substantial system potential:

“Based on what we’re seeing in this first six holes… I think there’s seven to ten million ounce potential at Golden Gate.”

Strategic Antimony Target Gains Importance

At Antimony Ridge, recent rock-chip sampling returned grades of 49.8% antimony, 1,420 g/t silver, and 3.12 g/t gold, confirming high-grade stibnite mineralisation at surface. With the United States heavily reliant on foreign antimony — primarily from China and Russia — domestic sources have become increasingly important for national-security and industrial supply.

RML has already submitted samples to Kingston Process Metallurgy in Canada for metallurgical characterisation, a key step toward assessing potential antimony product options.

Legislative Momentum Strengthens the Narrative

If enacted, H.R. 4090 would direct the Department of the Interior to identify mining projects suitable for expedited approval and prioritise those capable of bolstering U.S. critical-mineral supply chains. The legislation also calls for a review of regulatory bottlenecks and empowers the department to amend or rescind policies that hinder domestic mining.

In Idaho, where multi-agency approvals can stretch over several years, these reforms could significantly shorten development timelines.

Lindsay highlighted the geological and strategic parallels between Horse Heaven and the neighbouring Stibnite deposit — one of America’s foremost gold–antimony systems:

“We’ve got the exact same geology that they’ve got over at Stibnite… and what we’re seeing at Golden Gate is very similar to that system.”

Next Steps: Expanded Drilling Already Permitted

Resolution Minerals has secured approvals for 57 drill holes at Golden Gate, with 44 additional holes planned for 2026 to test the majority of the three-kilometre strike corridor.

As Lindsay explained:

“We’re permitted to drill fifty-seven holes at Golden Gate… and we have another forty-four holes to go next year to cover most of the three-kilometre strike.”

This work will be supported by the company’s agreement to acquire the Johnson Creek Mill — a past-producing local processing facility — positioning RML to accelerate both exploration and early-stage development options across the district.

Outlook

The Critical Mineral Dominance Act still requires full House consideration, Senate approval and presidential sign-off before becoming law. If designated a national-security priority, the bill could move rapidly through Congress — potentially within weeks — though competing legislative demands may extend the process into 2026.

If the legislation advances, analysts believe it could reshape operating conditions for US explorers, particularly those working on Federal land with exposure to strategic metals. Resolution Minerals sees this as a timely advantage, given the convergence of strong geological results, rising antimony importance, and favourable policy momentum as they move into their next phase of work.

In parallel, RML is progressing plans for a potential NASDAQ listing — a step that could expand access to U.S. capital markets at a moment when federal policy is increasingly aligned with domestic critical-mineral development. Historically, companies operating in priority districts and aligned with national-security mineral frameworks have attracted stronger institutional interest, and RML’s position within a recognised gold–antimony district strengthens that narrative.

Together, legislative tailwinds, district-scale exploration results and growing U.S. investor appetite for critical-minerals exposure may provide a more supportive backdrop for Resolution Minerals as it evaluates a dual-listing and advances its Idaho portfolio.
