US Critical Minerals Fast-Track: What 10 FAST-41 Mining Projects Mean for Copper, Lithium, and Inves

 The US government has granted FAST-41 status to 10 mining projects as part of a new push to accelerate critical minerals production on American soil. The centrepiece is Resolution Copper in Arizona, jointly owned by Rio Tinto (55%) and BHP (45%), which could supply up to 25% of total US copper demand for the next 40 years. That is roughly 450,000 tonnes per year from a single deposit. For investors tracking the critical minerals supply chain, this is the most significant permitting signal out of Washington in a decade.

The projects span copper, lithium, gold, antimony, potash, and coal. They were submitted to the Federal Permitting Dashboard on 4 April 2025 and formally added on 18 April 2025, following President Trump’s Executive Order 14157, signed on 20 March 2025, directing immediate measures to increase American mineral production. The initial 10 have since expanded to over 50 projects receiving FAST-41 coverage, but this first batch sets the tone.

What Is FAST-41 and Why Does It Matter for Mining Permits

FAST-41 was established in 2015 under the Fixing America’s Surface Transportation Act. It creates a structured, transparent permitting process for critical infrastructure, managed by the Federal Permitting Improvement Steering Council. Projects that receive FAST-41 coverage get coordinated permitting timetables, interagency accountability, and public tracking on the Federal Permitting Dashboard.

For mining, the relevance is straightforward. The average time to permit a mining project in the United States has historically been around 29 years. FAST-41 does not guarantee faster approval, but it forces agencies to coordinate and creates public visibility on delays. That matters to project sponsors who need financing certainty, and to investors who need to model when production revenue begins.

The Trump administration’s use of FAST-41 transparency authority for mining is a first. Prior administrations used the framework primarily for energy and transport infrastructure. Applying it to critical minerals is a direct policy response to US import dependence, particularly on China, which controls approximately 60% of global copper processing capacity.

Resolution Copper: The Anchor Project in the US Copper Supply Strategy

Resolution Copper is the flagship of this fast-track cohort for good reason. The deposit sits between 1,500 and 2,130 metres below the surface near Superior, Arizona, with an estimated average grade of 1.5% copper. If developed, it would become North America’s largest copper mine, producing approximately 18 million tonnes of copper over a 40-year mine life. Rio Tinto has indicated all output would be allocated for US consumption.

The project was discovered in 1995 beneath the old Magma Mine. Congress approved a land exchange in 2014 as part of a defence spending bill, but the environmental review and legal challenges have stalled progress for over a decade. The US Forest Service issued a 60-day notice of intent to republish the final environmental impact statement in April 2025, signalling meaningful progress.

The legal fight is not over. Apache Stronghold, a tribal advocacy group, has petitioned the Supreme Court (Apache Stronghold v. United States, No. 24-291) arguing that mining at Oak Flat violates tribal religious rights and federal preservation laws. The outcome of that case will shape the limits of executive authority to fast-track resource projects on contested land.

For investors, the tension is real. This is a world-class deposit that directly addresses US copper import dependence (the US imported roughly 890,000 tonnes of refined copper in 2024, a 16% year-on-year increase). But the legal and social licence risks remain material.

The Full List of Fast-Tracked Projects and What They Signal

The initial 10 FAST-41 transparency projects cover a deliberately broad commodity mix:

• Resolution Copper Project (Arizona) – Rio Tinto / BHP – Copper
• Stibnite Gold Project (Idaho) – Perpetua Resources – Gold and antimony
• Warrior Met Coal Mines (Alabama) – Warrior Met Coal – Metallurgical coal
• McDermitt Exploration Project (Oregon) – Jindalee Lithium – Lithium
• South West Arkansas Project – Standard Lithium / Equinor – Lithium
• Caldwell Canyon Mine Project – P4 Production – Phosphate
• Libby Exploration Project (Montana) – Hecla Mining – Silver and copper
• Lisbon Valley Copper Project (Utah) – Lisbon Valley Mining – Copper
• Silver Peak Lithium Mine (Nevada) – Albemarle Corporation – Lithium
• Michigan Potash Project (Michigan) – Michigan Potash & Salt Company – Potash
• 
  

The inclusion of antimony (Stibnite) is notable. Antimony is a critical defence input with near-total US import reliance on China. Perpetua Resources’ Stibnite project has since completed federal permitting, making it one of the early success stories of the FAST-41 transparency programme.

Three lithium projects in one cohort reflects the urgency around battery supply chains. McDermitt, operated by ASX-listed Jindalee Lithium, sits on one of the largest known lithium deposits in the United States. Standard Lithium’s Arkansas project, backed by Equinor, targets direct lithium extraction from brine, a technology play that could reshape domestic lithium economics.

The non-obvious read: the presence of metallurgical coal (Warrior Met) and potash (Michigan Potash) signals this is not purely an energy transition play. Washington is thinking about mineral security across agriculture, steelmaking, and defence, not just batteries and EVs.

What This Means for Mining Investment and Capital Allocation

The FAST-41 programme does not remove permitting risk. It structures it. For capital allocators, the distinction matters. A project on the Federal Permitting Dashboard has a public timeline that can be tracked, challenged, and priced. That is a material improvement over the opacity that has historically characterised US mine permitting.

The second-order effect is on project-level financing. Lenders and offtake counterparties have historically discounted US projects because of permitting uncertainty. A coordinated federal process, backed by executive order, changes the risk calculus. It does not eliminate it, particularly where legal challenges remain active, but it narrows the distribution of outcomes.

The broader portfolio signal: the US is serious about building a domestic critical minerals supply chain. The initial 10 projects have expanded to over 50 receiving FAST-41 benefits by late 2025. Companies with US-based projects in copper, lithium, antimony, rare earths, and uranium now have a clearer path, and a political tailwind, that did not exist 18 months ago

• The US granted FAST-41 status to 10 mining projects in April 2025, the first use of this transparency authority for critical minerals. Resolution Copper alone could supply 25% of US copper demand for 40 years.
• Legal challenges, particularly the Supreme Court case over Oak Flat, remain a material risk for the flagship project. Permitting acceleration does not equal permitting certainty.
• The commodity mix (copper, lithium, antimony, coal, potash) signals a whole-of-economy mineral security strategy, not just an energy transition play. Capital allocators should track the Federal Permitting Dashboard as a leading indicator of project timeline risk.

 What is the US critical minerals fast-track programme?

The US critical minerals fast-track programme uses FAST-41 transparency status to accelerate federal permitting for domestic mining projects. It was activated for mining in April 2025 following Executive Order 14157, signed by President Trump on 20 March 2025. Projects receive coordinated permitting timetables and public tracking on the Federal Permitting Dashboard, managed by the Federal Permitting Improvement Steering Council. The initial cohort included 10 projects spanning copper, lithium, gold, antimony, potash, and coal.

How much copper could Resolution Copper produce?

Resolution Copper could produce approximately 450,000 tonnes of copper per year over a 40-year mine life, totalling roughly 18 million tonnes. That output would meet up to 25% of annual US copper demand. The project is jointly owned by Rio Tinto (55%) and BHP (45%) and is located near Superior, Arizona. Rio Tinto has stated all copper produced would be allocated for US consumption.

Which mining companies have projects on the Federal Permitting Dashboard?

The initial 10 FAST-41 transparency projects include operations by Rio Tinto, BHP, Perpetua Resources, Warrior Met Coal, Jindalee Lithium, Standard Lithium, Equinor, P4 Production, Hecla Mining, Lisbon Valley Mining Company, Albemarle Corporation, and Michigan Potash & Salt Company. By late 2025, the programme had expanded to over 50 projects, adding companies across uranium, rare earths, nickel, and graphite.

Does FAST-41 status guarantee a mining project will be approved?

No. FAST-41 status does not guarantee project approval. It provides a structured, transparent permitting process with coordinated agency timelines and public accountability. Projects still face full environmental review, public consultation, and potential legal challenges. Resolution Copper, for example, remains subject to an active Supreme Court case (Apache Stronghold v. United States, No. 24-291) despite receiving FAST-41 status.
