WASHINGTON (April 7, 2026) – The Federal Permitting Improvement Steering Council (Permitting Council) is pleased to announce the latest mining project to gain FAST-41 Transparency status–the Antimony Ridge Project. Added to FAST-41 in response to President Trump’s Executive Order on Immediate Measures to Increase American Mineral Production, the project is expected to produce a critical supply of antimony, essential to addressing vulnerabilities in the U.S. supply chain.
“I am thrilled to welcome the Antimony Ridge Mine project as the 56th FAST-41 mining project,” said Emily Domenech, Permitting Council Executive Director. “Establishing a reliable domestic supply of antimony is vital to U.S. competitiveness and will help reduce dependence on foreign adversaries. I look forward to working with project sponsor Resolution Minerals Ltd to ensure a transparent, responsible, and efficient permitting process for this critical project.”
“Antimony is a key component in the production of defense weaponry and energy technology,” said U.S. Congressman Russ Fulcher. “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.”
Located in Valley County, Idaho, the project aims to restart a past-producing antimony mine that was active during World Wars I and II. Project sponsors intend to provide a near-term domestic supply of antimony to support federal efforts to secure a domestic source of critical metals. Developers anticipate extracting a minimum of 500 tons of high grade antimony ore from the historic pit area.
“Antimony Ridge is a high-priority development project for antimony, a key critical mineral, urgently needed for US military and industrial applications,” said Craig Lindsay, Resolution Minerals’ CEO - US Operations. “It is located in a friendly, tier-one jurisdiction in the center of Idaho, USA. The Project’s inclusion on the Federal Permitting Dashboard means Antimony Ridge is well positioned to advance efficiently through permitting. Resolution Minerals is grateful for the Permitting Council’s selection, which provides enhanced transparency and a public timeline for federal environmental reviews and authorizations. Once Resolution’s Plan of Operations is approved, we plan to immediately commence a significant bulk sampling program of high-grade Antimony ore and conduct an extensive drilling program. Antimony Ridge is expected to be a cornerstone of Resolution’s strategy to supply critical metals, including Antimony, Tungsten and Gold, from central Idaho in the USA.”
The U.S. Forest Service serves as the federal permitting lead for this project. Learn more about this project on the Federal Permitting Dashboard.
About the Permitting Council and FAST-41
Established in 2015 by Title 41 of the Fixing America’s Surface Transportation Act (FAST-41), the Federal Permitting Improvement Steering Council (Permitting Council) is a federal agency charged with improving the transparency and predictability of the federal environmental review and authorization process for certain critical infrastructure projects. The Permitting Council is composed of the Permitting Council Executive Director, who serves as the Council Chair; 13 federal agency Council members; and the Chair of the White House Council on Environmental Quality and the Director of the Office of Management and Budget. The Office of the Executive Director coordinates federal environmental reviews and authorizations for projects that seek and qualify for FAST-41 coverage, which are in turn entitled to comprehensive permitting timetables and transparent, collaborative management of those timetables on the Federal Permitting Dashboard.
