Freeport-McMoRan alone supplies roughly 70% of America’s refined copper, and it’s just one entry on a list of critical minerals companies USA policymakers and procurement teams are watching closely in 2026. Between the Inflation Reduction Act, Department of Energy loan guarantees, and a wave of Defense Production Act grants, Washington has put more capital behind domestic mining and processing in the past three years than in the previous three decades combined. This ranking looks at the ten companies doing the most to rebuild that supply chain on US soil.
How We Ranked the Top 10 Critical Minerals Companies USA
Rankings weight three factors: scale of current US production or committed capital, strategic importance to a mineral where America is import-dependent, and the strength of federal backing (DOE loans, DOD grants, EXIM Bank financing). Companies with operating US assets rank above development-stage projects with comparable federal support. Full rare earth element profiles are covered separately on Rare Earth Mining, CMN’s sister publication — REE-primary producers appear here only where their non-REE output is significant.
1. Freeport-McMoRan — Arizona & New Mexico (NYSE: FCX)
Freeport-McMoRan operates roughly 70% of US refined copper capacity from its Morenci, Bagdad, Sierrita, Chino, Safford and Miami sites across Arizona and New Mexico. Morenci alone produces over 900 million pounds of copper annually. The company is advancing a $4.3–4.5 billion 2026 capex program that includes early engineering on a Bagdad expansion targeting 200–250 million additional pounds of copper per year, with a final investment decision expected in the second half of 2026. See CMN’s copper price tracker for current market context. Risk: expansion economics depend on sustained copper prices above current cost-support levels.
2. Albemarle Corporation — Nevada & North Carolina (NYSE: ALB)
Albemarle operates Silver Peak, Nevada — currently the only active lithium-producing mine in the United States, running on brine extraction for over 50 years. The Bureau of Land Management approved an expansion of the site in February 2026, authorizing operations across 8,058 acres. Albemarle is separately pursuing a restart of its Kings Mountain, North Carolina spodumene deposit, with a DOE environmental assessment issued in March 2026, though the company has said the restart timeline has slowed given weak lithium prices, which remain down over 40% from year-ago levels. Risk: further price weakness could delay Kings Mountain indefinitely.
3. Lithium Americas Corp — Nevada (NYSE/TSX: LAC)
Lithium Americas is building Thacker Pass in Humboldt County, host to the largest known lithium resource in the world, through a joint venture with General Motors (62%/38% split). Phase 1 construction is backed by a $2.23 billion US Department of Energy loan; the company drew the first $435 million tranche in October 2025 and a second tranche in February 2026, with DOE holding warrants for a 5% equity stake as collateral. Phase 1 targets 40,000 tonnes per year of battery-quality lithium carbonate, with mechanical completion targeted for late 2027. Risk: the DOE deal was restructured in January 2026 specifically to protect taxpayer exposure, reflecting ongoing financing risk.
4. Piedmont Lithium — North Carolina (NASDAQ: PLL)
Piedmont Lithium is developing Carolina Lithium in Gaston County, roughly 20km along strike from the historic Hallman-Beam and Kings Mountain deposits. The company scrapped a separate Tennessee conversion facility in 2024 and consolidated that capacity into the Carolina project, aiming for integrated spodumene concentrate and lithium hydroxide production. Piedmont has cut its workforce and slowed spending amid the broader lithium price downturn affecting the whole sector. Risk: financing and permitting for Carolina Lithium remain unresolved, and the company has repeatedly revised its own timeline.
5. Graphite One — Alaska (OTCQX: GPHOF)
Graphite One is developing Graphite Creek on Alaska’s Seward Peninsula, the largest known natural graphite deposit in the United States, addressing a sector where America is 100% import-reliant. The project has drawn over $42 million in Department of Defense Title III and Defense Logistics Agency funding, completed a bankable feasibility study in Q2 2025, and became the first Alaska mining project added to the federal FAST-41 permitting dashboard, with a permitting decision targeted for September 2026. See CMN’s graphite price tracker for current market conditions. Risk: the plan depends on a separate Ohio processing facility that has not yet begun construction.
6. Energy Fuels Inc — Utah (NYSE American: UUUU)
Energy Fuels operates White Mesa Mill in Blanding, Utah — the only fully licensed conventional uranium processing facility in the United States and, since 2018, the country’s only primary vanadium producer. The mill also produces separated rare earth oxides from monazite feedstock; construction began in July 2026 on an expansion for commercial-scale heavy rare earth oxide output. CMN covers Energy Fuels’ uranium and vanadium role here; for the company’s rare earth and magnet supply chain position, see the full profile on Rare Earth Mining. Risk: three revenue streams sharing one facility increases operational complexity.
7. U.S. Strategic Metals — Missouri (private)
U.S. Strategic Metals operates the former Madison Mine site near Fredericktown, Missouri, producing cobalt and nickel sulfate alongside lithium carbonate, copper cathode and antimony sulfide from a mix of mined ore, tailings, and recycled lithium-ion battery material. The company has raised close to $500 million, including a $230 million financing package from Appian Capital in 2024 and federal EB-5 program approval, positioning it as one of the few vertically integrated domestic cobalt and nickel processors in North America. Risk: USSM faces an unresolved federal Clean Water Act lawsuit tied to the Fredericktown site, filed in January 2024.
8. NioCorp Developments — Nebraska (NASDAQ: NB)
NioCorp is constructing Elk Creek in Johnson County, Nebraska, home to the highest-grade niobium resource in North America alongside significant scandium and titanium. The company has raised over $500 million since 2025, has 75% of planned niobium output under offtake and 12 tonnes per year of scandium contracted, and began mine portal construction in February 2026. NioCorp is pursuing a $780 million loan from the US Export-Import Bank, with an updated bankable feasibility study expected mid-2026. Risk: Elk Creek remains pre-revenue, and full project financing has not yet closed.
9. MP Materials — California (NYSE: MP)
MP Materials operates Mountain Pass, the only integrated rare earth mine and processing site in North America, and received a $400 million Department of Defense equity investment in 2025 tied to a 10-year magnet offtake agreement. Given the lane this list focuses on, MP Materials’ full rare earth and magnet supply chain story is covered in CMN’s own MP Materials DoD deal profile rather than repeated here.
10. Coeur Mining — Idaho (NYSE/TSX: CDE)
Coeur Mining reported record Q2 2026 revenue of $1.1 billion following its first full quarter with the newly acquired New Afton and Rainy River operations, producing 11.4 million pounds of copper alongside record gold and steady silver output. Full-year 2026 guidance stands at approximately 45 million pounds of copper. See CMN’s full Coeur Mining Q2 2026 results coverage for detailed guidance and project updates. Risk: the company trimmed nine-month production guidance even as full-year figures held, pointing to near-term ramp-up risk at the Canadian assets.

The Outlook for Critical Minerals Companies USA in 2026
The pattern across this list is consistent: nearly every company here is leaning on federal capital — DOE loans, DOD Title III grants, EXIM Bank financing — because private markets alone haven’t closed the funding gap for domestic mining and processing. That dependence cuts both ways. It has de-risked projects like Thacker Pass and Graphite Creek that might otherwise have stalled, but it also means financing timelines for critical minerals companies USA-wide are now tied to federal budget cycles and loan office throughput as much as to commodity prices. Watch for Graphite One’s September 2026 permitting decision and NioCorp’s EXIM Bank outcome as the next signals of whether that federal-backing model scales. For the global picture, see CMN’s Top 10 Critical Minerals Mining Companies 2026 ranking.
Production figures and financing amounts reflect company and federal agency disclosures current as of August 2026 and are subject to revision. This article is for informational purposes only and does not constitute investment advice.
Which is the largest of the critical minerals companies USA has today?
By share of domestic production, Freeport-McMoRan is the largest, supplying roughly 70% of US refined copper output from its Arizona and New Mexico operations.
What criteria determines this ranking?
Rankings weight current US production scale, strategic importance for import-dependent minerals, and the strength of federal financial backing through DOE, DOD or EXIM Bank programs.
Why isn’t MP Materials ranked higher given its DoD deal?
MP Materials’ rare earth and magnet supply chain role is significant, but CMN covers that story in depth in a dedicated profile rather than duplicating it here; this list weights companies whose primary output falls outside the rare earth lane.
Which of these companies has no operating US production yet?
Lithium Americas, Piedmont Lithium, Graphite One and NioCorp Developments are all pre-production, advancing projects toward construction or first output rather than running active US mines.
What could change these rankings in 2026?
Graphite One’s September 2026 federal permitting decision and NioCorp’s EXIM Bank loan outcome are the two most likely near-term catalysts to reshape this list.
