PERMITTING COUNCIL SUPPORT EXPECTED TO ACCELERATE AGGRESSIVE EXPLORATION AND DEVELOPMENT PROGRAM ACROSS ENTIRE GOLDEN GATE TARGET AS RESOLUTION CONTINUES TO DEVELOP ITS INTEGRATED IDAHO ANTIMONY-TUNGSTEN-GOLD CRITICAL METALS PLATFORM

June 17, 2026 (Source) — HIGHLIGHTS

This is the second FAST-41 status granted to Resolution Minerals, demonstrating the high calibre of the Golden Gate asset and its strategic value as a potential source of U.S. domestic tungsten supply, and highlights the level of engagement RML has with the U.S. Government and the Permitting Council, and the attention Resolution’s projects are receiving from the highest levels of the current Administration.
FAST-41 is a special permitting framework being utilised by the Trump Administration to accelerate permitting and the development of critical U.S. infrastructure projects and to provide solutions for U.S. national security.
RML’s Golden Gate Project was added to the FAST-41 Transparency Dashboard in response to President Trump’s Executive Order on Immediate Measures to Increase American Mineral Production¹, to reduce reliance on foreign adversaries for the supply of critical minerals, especially during times of war.
RML has been working closely with key Federal agencies and Administration leadership, including the Permitting Council, which has reviewed RML’s U.S. assets and has recognised their strategic importance to addressing the United States’ critical metals supply deficit and lack of domestic production.
With RML’s Antimony Ridge Project receiving FAST-41 Transparency status in April 2026, both of the Company’s primary development targets at the Horse Heaven Project, Antimony Ridge and Golden Gate, have been prioritised by the U.S. Government for streamlined permitting.
The Golden Gate and Antimony Ridge targets are within RML’s 15,000-acre Horse Heaven Tungsten-Antimony-Gold Project located in Idaho, USA, directly adjacent to Perpetua Resources’ recently permitted ~A$3.5 billion Stibnite Gold Project.
A Plan of Operations for Golden Gate has been submitted to, and accepted by, the US Forest Service for an exploration and development program that will include construction of new roads between Golden Gate North and Golden Gate South and allow up to 340 drill holes and 2,000 feet of trenching.
The Golden Gate Project includes the past-producing Golden Gate Tungsten Mine, which operated intermittently between the period from approximately 1952 to 1980, with reported tungsten production grades ranging between 1.5% and 2.0%.
The combination of Golden Gate and Antimony Ridge positions Resolution to pursue an integrated critical metals development pathway spanning exploration, metallurgy, and potential downstream processing in a tier-one U.S. jurisdiction.
FAST-41 status is expected to fast-track permitting, enhance investor visibility and support engagement with potential strategic partners and funding sources aligned with the U.S. critical minerals policy.
FAST-41 status bodes extremely well for the Company’s upcoming NASDAQ listing.

Resolution Minerals Ltd (ASX: RML; OTCQB: RLMLF) (“Resolution” or the “Company”) is pleased to announce that its Golden Gate Project in Idaho, USA has been selected for inclusion in the U.S. Federal FAST-41 Permitting Transparency Program.

FAST-41 designation is expected to accelerate permitting timelines through enhanced inter-agency coordination, transparent milestone tracking and dedicated federal oversight. The Program provides Resolution with a clear pathway to advance its proposed bulk sampling and drilling activities at Antimony Ridge, a high-grade, past producing antimony project, located within the Company’s 100% owned Horse Heaven Project.

Importantly, FAST-41 selection supports Resolution’s broader strategy to develop a U.S.-focused critical mineral platform. Golden Gate is one of several advancing components within Horse Heaven Project, which also includes:

A recently acquired processing mill and infrastructure known as the Johnson Creek Tungsten Mill.
Historical tungsten stockpiles located adjacent to the Golden Gate Tungsten Mine portal and at the Johnson Creek Mill with potential near-term development optionality.
A fully funded, ongoing Phase 2 drilling program at Golden Gate, comprising up to 45 holes targeting resource definition.

Together, these assets position Resolution to pursue an integrated development pathway spanning exploration, metallurgy and potential downstream processing of antimony, tungsten, and gold in a tier-one U.S. jurisdiction.

Golden Gate is located immediately adjacent to Perpetua Resources’ Stibnite Gold Project, highlighting the region’s growing importance as a strategic hub for U.S. critical minerals. With the United States seeking to secure domestic supply of key metals such as antimony, Resolution is well placed to contribute to supply chain resilience while advancing multiple near-term development catalysts.

The inclusion of Golden Gate in the FAST-41 program follows closely on the designation of RML’s Antimony Ridge Project as a FAST-41 project. It is the intention of the US Forest Service to permit both the Antimony Ridge Plan of Operation and the Golden Gate Plan of Operation under one NEPA process, helping to streamline ongoing permitting at both projects.

Craig Lindsay, Resolution’s CEO – US Operations, commented:

“We are very pleased that Golden Gate has been selected for FAST-41 Transparency Coverage. We now have two separate development targets within the Horse Heaven Project under the FAST-41 program. Interestingly, I am not aware of any other critical metals company with two FAST-41 projects, which I believe is a mark of the potential importance of Horse Heaven in the US achieving its goal of developing domestic supplies of both antimony and tungsten.

Golden Gate represents a key piece of Resolution’s broader strategy to develop a 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 Projects and the Permitting Council

The Washington, DC-based Permitting Council was established by Congress in 2015 under Title 41 of the Fixing America’s Surface Transportation Act (FAST-41) to improve the efficiency, transparency and accountability of the federal permitting process.

The Council coordinates environmental reviews and authorisations across multiple federal agencies, acting as a central project manager across for qualifying projects. FAST-41 projects benefit from structured inter-agency coordination, defined permitting timelines and public tracking via the Federal Permitting Dashboard.

The Permitting Council is comprised of the Executive Director (Chair), and 15 other members, including the Deputy Secretary (or equivalent) from 13 Federal agencies, the Chair of the Council on Environmental Quality (CEQ), and the Director of the Office of Management and Budget (OMB). The Office of the Executive Director (OED) executes on the actions of the Council, and Permitting Council statutory authorities, programs, and initiatives. The Office of the Executive Director coordinates federal environmental reviews and authorisations for projects that qualify for FAST-41 coverage, which are in turn entitled to public permitting timetables and transparent, collaborative management of those timetables on the Federal Permitting Dashboard.

More information on the Permitting Council and FAST-41 can be found at www.permitting.gov.

Next Steps

Resolution will work closely with its primary permitting authority, the US. Forest Service, to advance the Golden Gate Plan of Operations through the FAST-41 process.

Following approval, the Company intends to commence a significant drill campaign intended to both increase the drill coverage of the Golden Gate North and Golden Gate South targets and confirm whether the gold and tungsten mineralization is linked geologically (the area between North and South have never been drilled, but RML has developed a geologic model that suggests the potential for both targets to be one large contiguous body of mineralisation).

On a parallel basis, RML is continuing to implement its ongoing 13,700 metre (45,000 foot) drill program at Golden Gate, with 22 holes currently completed and initial results for the first several holes expected by the end of July.
