Rare earth elements (REEs) are crucial for technologies like smartphone cameras and defense systems.
A select few from the group of 17 are also vital to the expanding electric vehicle industry — neodymium and praseodymium are used in permanent magnet synchronous motors used in EV drive trains.
China’s dominance in rare earth production and reserves has prompted countries like the US, Canada and Australia to boost their own mining and processing efforts to secure their supply chains. The pressure on these nations to establish strong supply chains is likely to grow when a US tariff on imports of Chinese rare earth magnets begins in 2026.
The 25 percent tariff, announced by the US government in May 2024, aims to both protect American industries from China’s trade practices and support domestic production. One form of magnets the tariffs will affect is sintered neodymium-iron-boron (NdFeB) magnets, crucial for electric vehicle motors and wind turbines.
This marks the first time rare earth magnets are included in Section 301 tariffs, signaling a significant move in the US-China trade conflict. The initiative is part of broader efforts to bolster US energy and national security.
Meanwhile, the EU is also seeking to reduce its reliance on Chinese rare earths through a new law enacted in May, which aims to significantly boost domestic production of critical minerals, including rare earths, by 2030.
In early July, China’s State Council introduced new regulations to tighten control over the country’s rare earth resources and secure its supply chain. Taking effect on October 1, 2024, these new rules impose strict oversight on the mining, smelting and trading of rare earth elements. They also ban the export of technology for extracting and separating rare earths as well as for making rare earth magnets.
US rare earths stocks
To circumvent Chinese tariffs, the US is striving to secure a stable domestic supply of REEs outside China. The US has vast rare earths reserves and is the second largest global REE producer thanks to its sole operating mine, Mountain Pass. However, it currently lacks sufficient processing facilities. American rare earth companies are working to address this imbalance, presenting investment opportunities for those looking to capitalize on the market’s growth potential.

1. MP Materials (NYSE:MP)
Market cap: US$2.9 billion
Share price: US$17.54
MP Materials, the largest producer of rare earths outside China, focuses on high-purity separated neodymium and praseodymium (NdPr) oxide, heavy rare earths concentrate, lanthanum, and cerium oxides and carbonates.
The company went public in mid-2020 after acquiring the Mountain Pass mine in California, the only operational US-based rare earths mine and processing facility. In Q3 2023, MP Materials began producing separated NdPr, marking a significant milestone. The company plans to increase rare earth oxide production by 50 percent within four years.
In April, MP Materials was awarded US$58.5 million to support the construction of the first fully integrated rare earth magnet manufacturing facility in the US. This funding, part of the Section 48C Advanced Energy Project tax credit, was granted by the IRS and Treasury following a selection process that evaluated around 250 projects based on their technical and commercial viability, as well as their environmental and community impact.
Located in Fort Worth, Texas, the facility will produce the NdFeB magnets crucial for EVs, wind turbines and defense systems. The company is targeting commercial production by late 2025. MP Materials will source raw materials from its Mountain Pass mine, creating an end-to-end supply chain with integrated recycling.
During the second quarter of 2024, MP reported that NdPr production more than doubled quarter-over-quarter to 272 metric tons. The company expects that output will increase a further 50 percent in the third quarter.
2. Energy Fuels (NYSEAMERICAN:UUUU,TSX:EFR)
Market cap: US$914.91 million
Share price: US$5.59
Energy Fuels is a leading US uranium and rare earths company that operates key uranium production centers including the White Mesa mill in Utah and the Nichols Ranch and Alta Mesa projects in Wyoming and Texas.
The company finished the construction of Phase 1 REE separation infrastructure at White Mesa in early 2024, and in June it reported the successful commercial production of separated neodymium-praseodymium that meets the specifications required for REE-based alloy manufacturing.
According to the company, it believes it is the first US company in decades to achieve commercial-scale, on-spec rare earths separation from monazite. The Phase 1 REE separation circuit was completed under budget and is now operating at full capacity. Energy Fuels anticipates commercial production of 850 to 1,000 metric tons of NdPr per year, making it one of the largest outside China.
Additionally, the mill will produce a heavy REE concentrate for pilot-scale tests to potentially develop commercial dysprosium and terbium separation facilities in the future.
Energy Fuels has also made moves to secure sources of monazite sand to process at its White Mesa mill. In 2023, the company acquired the Bahia project in Brazil to potentially supply 3,000 to 10,000 MT of REE-bearing monazite sand annually.
In early June 2024, Energy Fuels executed a joint venture with Astron (ASX:ATR) for Astron’s Donald rare earth and mineral sands project in Victoria, Australia, of which Energy Fuels now has the option to earn 49 percent. After garnering shareholder approval, the joint venture was finalised in late September. Donald is expected to begin production as early as 2026 and supply the White Mesa mill with 7,000 to 8,000 MT of monazite sand in rare earth concentrate annually in Phase 1, with plans to expand output in subsequent phases.
Adding to its rare earth roster, Energy Fuels announced plans to acquire Australian mineral sands company Base Resources (ASX:BSE) in September.
Commenting on the deal and the new assets, Energy Fuels CEO Mark Chalmers highlighted the rare earth portfolio potential. “The Toliara, Bahia and Donald projects are expected to become large-scale, world-class, and low-cost heavy mineral sand projects in the coming years, producing titanium, zirconium and rare earth minerals,” he said.
3. NioCorp Developments (NASDAQ:NB)
Market cap: US$77.32 million
Share price: US$2.00
NioCorp Developments is advancing its Elk Creek project in Nebraska, a leading critical minerals venture featuring North America’s highest-grade niobium deposit under development, with significant scandium production capacity. An updated 2022 feasibility study highlighted extended mine life, improved ore grades and enhanced economics for niobium, scandium and titanium.
Recent metallurgical testing has demonstrated the ability to produce high-purity magnetic rare earth oxides at a recovery rate of 92 percent or higher. These results will inform an updated feasibility study, expected in 2024, incorporating rare earth elements into the project’s mineral reserves.
In April, the company delisted from the TSX due to significantly lower trading volumes than its NASDAQ listing.
A day later, NioCorp announced plans to explore the feasibility of integrating the recycling of permanent rare earth magnets into its proposed Elk Creek critical minerals project in Southeast Nebraska. An assessment will be undertaken to better understand the technical and commercial viability of recycling post-consumer neodymium-iron-boron magnets back into separated rare earth oxides, which can then be utilized in the production of new NdFeB magnets.
The initial phase of this investigation will involve bench-scale testing, with potential progression to demonstration-scale testing based on results. Notably, this initiative will be conducted independently of NioCorp’s ongoing efforts to update its Elk Creek project’s feasibility study.
In May, the company shared the results of a scoping study focused on using a Railveyor system to electrify the Elk Creek mine, which the study found could cut costs, shorten the timeline to full commercial production and lower the mine’s carbon footprint. The system would deliver ore to processing facilities using a narrow-gauge light rail system.
In the preliminary fiscal year financial results released on August 26, NioCorp reported a net loss of US$11.395 million, or US$0.30 per share. The results for the period ending June 30, 2024, marked a year-over-year improvement compared to the previous fiscal year’s loss of US$40.08 million, or US$1.34 per share.
