A list of rare earth mining companies is only useful if it tells you which ones actually produce. A company with a promising drill result and a company shipping separated oxide often sit side by side, and nothing on the list says which is which. A buyer who treats a drill result as supply can wait years for oxide that never ships. The companies below are grouped by region. It is not a ranking, and nothing here is a buy list. For the full American roster, see the REEx guide to US rare earth companies.

What makes a rare earth mining company a producer?
A rare earth mining company becomes a producer when it sells something a manufacturer can use, which in this industry usually means separated oxide. Rare earths come out of the ground mixed together in the same ore. A mine that ships concentrate leaves separation to someone else, and separation is the hardest and most valuable step.
For decades, the companies doing that separation have mostly been in China. The useful question for any company is how far down the chain it reaches on its own: mine, concentrate, separated oxide, metal, magnet. The further it reaches, the more it controls price and customers. A company that has not built its plant is a developer, whatever its press releases call it.
Each step in that chain is a different business with different risks:
- Mining and concentration. Digging ore and upgrading it into a concentrate. Many deposits never reach this stage, because permitting and financing a mine takes years.
- Cracking and separation. Dissolving the concentrate and pulling individual elements apart through long chains of solvent extraction stages. This is the step REEx calls the messy middle.
- Metal and alloy making. Turning oxides such as neodymium and praseodymium into metal for magnet plants.
- Magnet making. Pressing and sintering NdFeB magnets for motors, wind turbines and defense systems. Heavy rare earths like dysprosium and terbium keep those magnets working at high temperatures.

Australia: producers and builders
Australia's rare earth companies sit at very different stages. Government money funds most of Iluka's refinery, and Arafura's project is waiting on government-backed equity and debt.
Lynas Rare Earths (ASX: LYC)
Lynas Rare Earths is the reference point for what a non-Chinese producer looks like. It mines at Mt Weld in Western Australia, processes concentrate at Kalgoorlie and separates oxides in Malaysia, including the heavy rare earths dysprosium and terbium. Japanese partner JARE is both its anchor customer and a lender. REEx covers Lynas's quarterly sales and pricing.
Lynas's biggest risk is its Malaysian license. A license condition sets a deadline to change how the plant handles residue, and the license could be revoked for non-compliance.
Iluka Resources (ASX: ILU)
Iluka Resources is a mineral sands miner. Its Eneabba refinery in Western Australia is designed to turn a large monazite stockpile into separated oxides, including heavy rare earths. Most of the money comes from a non-recourse Australian government loan, which makes Eneabba as much a policy project as a commercial one.
The cost estimate and future feed are its two risks. Part of that feed is meant to come from other companies' mines, so Eneabba depends on projects it does not control. REEx tracks that risk in its Eneabba refinery and heavy rare earth coverage.
Arafura Rare Earths (ASX: ARU)
Arafura Rare Earths owns the Nolans project in the Northern Territory. The project puts a mine and a plant that makes separated NdPr oxide on one site. REEx covered the start of works at Nolans.
Arafura's test is closing its project debt, because its cornerstone equity is expected to complete at that same step. Arafura has also said it will stop naming offtake customers unless the name itself is material. That makes its customer book harder to check from outside.
China: the state-owned groups that set the market
China's rare earth industry has been consolidated into a few state-controlled groups. Beijing allocates annual mining and smelting quotas to designated producers, and these groups are the ones reported to receive them. Beijing no longer publishes those quotas, so Chinese supply is hard to read from outside. Chinese supply also sets the benchmark price that most contracts reference.
China Northern Rare Earth (SSE: 600111)
China Northern Rare Earth processes ore from the Bayan Obo deposit in Inner Mongolia. Its sister company Baotou Steel, under the same state-owned parent, supplies that ore. It covers every step from separation through metals and magnets.
Depending on a related-party ore supplier is China Northern's structural weak point. REEx follows its results and output.
China Rare Earth Group (unlisted)
China Rare Earth Group is a central state-owned group formed from several producers. Its core is the southern ionic clays, historically China's main domestic source of heavy rare earths. The group itself is unlisted but controls listed subsidiaries. It reports little capacity or permit data, a gap REEx flagged in its coverage of the group's integration.
United States: rare earth miners and processors
Most of these US rare earth mining companies have federal money or a federal customer, and each faces a different test:
- MP Materials (NYSE: MP): mines and separates at Mountain Pass, California, and makes magnets in Texas. The Department of War is its shareholder, price guarantor and future magnet buyer, so US policy shapes MP's revenue. Its Fort Worth magnet plant is contracted to supply GM and, later, Apple. Cost or delay at its magnet plants is the open risk.
- Energy Fuels (NYSE American: UUUU): a uranium miner that has separated NdPr at its White Mesa Mill in Utah and is developing mineral sands projects abroad. Its rare earth plan leans on government financing and its VAC magnet deal, so check the status of both before treating the plan as funded.
- USA Rare Earth (Nasdaq: USAR): a magnet plant in Oklahoma, the Round Top deposit in Texas and, through Serra Verde, a producing mine in Brazil. Its test is whether its magnet customer MOUs become binding contracts.
- NioCorp Developments (Nasdaq: NB): the Elk Creek niobium, scandium and rare earth project in Nebraska. Its test is construction financing.
- American Rare Earths (ASX: ARR): the Halleck Creek deposit in Wyoming, an early-stage project. Its estimated build cost is far above its cash, and its auditor has raised doubt that it can keep operating. REEx covered both in Halleck Creek recovery and funding risks.
The full US list, including the separators and magnet makers left out here, is in US rare earth companies: who actually mine, separate, and make magnets.
Canada, Brazil and Europe: separators, magnet makers and a Brazilian mine
Ucore Rare Metals (TSXV: UCU)
Ucore Rare Metals is a Canadian company whose separation plant is in Louisiana. The plant runs on Ucore's own RapidSX solvent extraction technology, and US defense funding has paid for part of the early work. Its Alaska rare earth property is held for later.
Ucore's own risk disclosures say RapidSX may not perform at commercial scale as expected. Feedstock contracts are the other gap. REEx reported on the RapidSX scale-up test.
Neo Performance Materials (TSX: NEO)
Neo Performance Materials runs a rare earth separation plant at Sillamäe in Estonia and a sintered magnet plant at Narva nearby. That puts separation and magnet making under one owner. REEx covered the start of commercial magnet production at Narva.
Its risks are operating cash outflows, which Neo attributes partly to inventory and a patent settlement, and, as REEx has reported, Silmet's reliance on Russian feedstock.
Serra Verde
Serra Verde, owned by USA Rare Earth, operates the Pela Ema ionic clay mine in Goiás, Brazil. The US government backed it with DFC financing as a Western-aligned source of rare earths, including heavy rare earths.
Its output goes to a buyer backed by the US government under a long-term take-or-pay contract with price floors. That contract is only as strong as the buyer's ability to fund it.
How should you judge a rare earth mining company's announcements?
Judge a rare earth mining company by the verbs in its filings, because headlines rarely carry the qualifiers. A "conditional commitment" still needs due diligence and final documents. A "letter of interest" or "letter of support" from a lender is not a loan.
A "final investment decision" means construction can start, while the money may still be waiting on contractual close. "Nameplate capacity" is what a plant was designed to make, which is different from what it produces in a quarter. An MOU or a cooperation framework is usually non-binding, and a take-or-pay offtake is among the strongest customer commitments a developer can show.
Four checks catch most overstatement:
- Is the financing closed or only approved? Find the words "drawn," "closed," or "executed" before treating money as real.
- Is the offtake binding? Look for take-or-pay terms, a named counterparty, and a start date.
- Does the company have its own feedstock? A separator with no contracted feed has a plant with nothing to run through it.
- Who sets the price? A government price floor protects revenue only as long as the policy behind it lasts.
For the elements themselves, start at the rare earth elements hub.

Frequently asked questions
Who are the biggest rare earth mining companies?
China Northern Rare Earth and China Rare Earth Group are the two state-owned groups reported to hold China's mining quotas. Beijing no longer publishes the quota figures, so their output can't be checked directly. Outside China, the comparison table on this page lists which companies separate rare earth oxides, with a dated status for each.
Which rare earth mining companies produce outside China?
Lynas Rare Earths, MP Materials and Neo Performance Materials separate rare earths outside China. Energy Fuels has produced separated NdPr in Utah, and Serra Verde mines an ionic clay deposit in Brazil. Iluka Resources and Arafura Rare Earths are developing plants in Australia, and the comparison table shows how far each has gotten.
Where are rare earths mined outside China?
Outside China, rare earth ore is mined at Mt Weld in Western Australia, Mountain Pass in California and the Pela Ema ionic clay mine in Brazil, among other sites. Mineral sands operations, such as Iluka's in Australia, also produce monazite, a mineral that carries rare earths. Many more deposits sit at the study stage.
Why is separation harder than mining?
Separation has to split chemically similar elements from one another to high purity, which digging ore never requires. That takes long chains of solvent extraction stages, careful process control and years of tuning before a plant runs to specification. It also produces chemical and radioactive residues that need permits. That is why a mine can run for years while its owner still ships concentrate to someone else for separation.
Why does government funding matter so much for rare earth companies?
Rare earth plants cost hundreds of millions to billions of dollars, and they compete against Chinese supply that sets the benchmark price. Commercial lenders hesitate, so Western governments have stepped in with loans, equity stakes and price floors. That support lowers a project's risk but ties the project to government policy.
