Resolution Minerals Ltd (ASX: RML; OTCQB: RLMLF) has secured inclusion of its Antimony Ridge Project in Idaho, USA in the U.S. Federal FAST-41 Permitting Transparency Program, a significant milestone expected to accelerate permitting timelines and enhance development certainty.
FAST-41 is a special permitting framework designed to streamline approvals for critical infrastructure projects deemed strategically important to U.S. national security. Antimony Ridge was selected following a U.S. Executive Order aimed at increasing domestic mineral production and reducing reliance on foreign supply chains for critical minerals.
The designation highlights the strategic importance of Antimony Ridge as a potential domestic source of antimony, a critical metal used in defence, energy and industrial applications. The United States currently faces constrained supply of antimony and tungsten due to geopolitical tensions and export restrictions.
Resolution’s inclusion in FAST-41 is expected to deliver enhanced inter-agency coordination, defined permitting timelines and transparent milestone tracking, providing a clear pathway to advance bulk sampling and drilling activities at the project.
The Company has already submitted a Plan of Operations targeting bulk sampling of near-surface high-grade antimony mineralisation and a drilling program of up to 250 holes to define the scale of the system.
Antimony Ridge forms part of Resolution’s broader Horse Heaven Project, which includes recently acquired processing infrastructure at Johnson Creek, historical tungsten stockpiles, and a fully funded Phase 2 drilling program at Golden Gate comprising up to 45 holes. Together, these assets support an integrated development strategy spanning exploration, metallurgy and potential downstream processing in a tier-one U.S. jurisdiction.
The project is located adjacent to Perpetua Resources’ Stibnite Gold Project, reinforcing the region’s growing importance as a hub for U.S. critical minerals.
U.S. Congressman Russ Fulcher commented:
“Antimony is a key component in the production of defense weaponry and energy technology. I am pleased to see the Antimony Ridge Project receive FAST-41 transparency status. Ensuring we have a strong domestic supply of this natural resource – sourced right here in Idaho in an environmentally friendly way – is vital to U.S. national defense and economic security.”
Craig Lindsay, Resolution’s CEO - US Operations, commented:
“FAST-41 selection is a significant step forward for Antimony Ridge and reinforces the strategic importance of this project within the United States.
This designation provides a clear and more efficient pathway through permitting, allowing us to progress bulk sampling and drilling activities with greater confidence and transparency.
Antimony Ridge is a key part of Resolution’s broader strategy to develop U.S.-based critical minerals platform. With exploration, processing infrastructure and multiple development pathways now coming together at Horse Heaven, we believe the Company is uniquely positioned to capitalise on strong demand for antimony, tungsten and gold.”
FAST-41 status is also expected to support Resolution’s upcoming NASDAQ listing and enhance engagement with potential strategic partners and funding sources aligned with U.S. critical minerals policy.
Next steps
Resolution will work closely with the U.S. Forest Service to advance the Antimony Ridge Plan of Operations through the FAST-41 process. Following approval, the Company intends to commence bulk sampling alongside an extensive drilling campaign.
In parallel, Resolution is preparing to begin a major Phase 2 drilling program at Golden Gate in May 2026, comprising up to 13,700 metres of diamond drilling designed to expand known mineralisation and support progression toward a maiden Mineral Resource Estimate
