Northern Minerals (ASX: NTU) is developing Browns Range, one of the world’s most advanced heavy rare earth element (HREE) projects located outside China. The East Kimberley project hosts a JORC-compliant resource of 9.3 Mt at 0.62% total rare earth oxide (TREO), with dysprosium and terbium grades that place it among the highest-quality HREE deposits in Australia.
Company Overview
Northern Minerals was founded in 2006 and is headquartered in Perth, Western Australia. The company is listed on the Australian Securities Exchange under the ticker NTU, with its strategy focused exclusively on heavy rare earth elements — a narrower and more defensible position than peers targeting light REE (LREE) such as neodymium and praseodymium.
Ownership structure has drawn regulatory attention. Chinese-linked shareholders have previously held material stakes in Northern Minerals, prompting Foreign Investment Review Board (FIRB) scrutiny. In 2023, FIRB issued orders requiring Chinese investors to divest. The company has since worked to broaden its shareholder base among Western institutional investors, a strategic priority as Western governments tighten oversight of HREE assets.
Browns Range — Key Asset and Operations
The Browns Range project sits approximately 160 km southeast of Halls Creek in the East Kimberley region of Western Australia. The deposit is hosted in xenotime mineralisation — a phosphate mineral that concentrates heavy rare earths at grades rare in non-Chinese deposits.
The Wolverine deposit is the highest-grade zone within the broader Browns Range tenement package, with dysprosium and terbium grades significantly above global averages for hard-rock HREE deposits. The project’s JORC resource of 9.3 Mt at 0.62% TREO (as reported in company filings) contains meaningful concentrations of dysprosium oxide (Dy₂O₃), terbium oxide (Tb₄O₇), yttrium oxide (Y₂O₃), and holmium oxide (Ho₂O₃).
Northern Minerals completed a pilot plant campaign at Browns Range, processing ore through a conventional flowsheet of crushing, gravity separation, and flotation to produce a xenotime concentrate. Pilot plant results confirmed the processing route is technically viable. The company has indicated that a commercial-scale operation would require a dedicated separation circuit or an offtake arrangement with an established rare earth processor.
2026 Developments and Strategic Direction
Northern Minerals is advancing feasibility work for a potential commercial-scale operation at Browns Range, though a final investment decision has not been announced as of early 2026. The company’s near-term focus is on securing project financing and a binding HREE offtake agreement with a Western downstream customer — a prerequisite most lenders and government funders require before committing capital to greenfield rare earth developments.
Australia’s Critical Minerals Strategy and the Australian Critical Minerals Prospectus identify heavy rare earths as a national priority, positioning Browns Range as a potential beneficiary of federal support mechanisms. Northern Minerals has engaged with government stakeholders, though no binding funding commitments have been publicly confirmed.
The company’s ability to advance to a construction decision in 2026 depends on three variables: completion of a bankable feasibility study, resolution of project financing, and execution of an offtake agreement with a customer capable of processing xenotime concentrate into separated oxides.
Northern Minerals in the Global HREE Market
Heavy rare earth elements — particularly dysprosium and terbium — are essential additives in neodymium-iron-boron (NdFeB) permanent magnets. Both elements raise the operating temperature threshold of magnets used in EV traction motors and direct-drive wind turbine generators. Without dysprosium and terbium, magnet performance degrades under the thermal loads of high-power applications.
China accounts for the overwhelming majority of global HREE supply, with ionic clay deposits in Jiangxi province producing most of the world’s dysprosium and terbium. Projects capable of supplying these elements from outside China remain scarce. Browns Range is one of a small number of advanced-stage HREE projects in Western jurisdictions — a peer group that also includes ionic clay projects in Brazil and hard-rock deposits in Greenland and Canada, most of which remain at earlier development stages.
Current dysprosium prices and terbium prices reflect the supply concentration risk that makes Western projects like Browns Range strategically relevant to magnet manufacturers and their automotive and defence customers.

Northern Minerals enters 2026 with a technically de-risked processing route and a deposit that addresses one of the supply chain’s most acute gaps. The key variables to watch are the bankable feasibility study completion date, whether a Western offtake partner commits to a long-term xenotime concentrate agreement, and whether government financing support — under Australia’s critical minerals framework or allied nation programmes — bridges the capital gap to a construction decision.
What does Northern Minerals produce?
Northern Minerals is developing Browns Range to produce a xenotime concentrate containing heavy rare earth elements, primarily dysprosium, terbium, yttrium, and holmium. The company has completed a pilot plant campaign confirming the processing route. Commercial production has not commenced as of early 2026.
Where is Northern Minerals’ Browns Range project located?
Browns Range is located approximately 160 km southeast of Halls Creek in the East Kimberley region of Western Australia. The project is hosted in xenotime mineralisation, which concentrates heavy rare earth elements at grades rare outside China.
What is the Browns Range JORC resource estimate?
Browns Range has a JORC-compliant resource of 9.3 Mt at 0.62% total rare earth oxide (TREO), as reported in Northern Minerals’ company filings. The Wolverine deposit within the tenement package represents the highest-grade zone, with dysprosium and terbium grades above global averages for hard-rock HREE deposits.
Why are Northern Minerals’ heavy rare earths strategically important?
Dysprosium and terbium are critical additives in NdFeB permanent magnets used in EV traction motors and wind turbine generators. China supplies the majority of global HREE production. Advanced projects outside China capable of supplying these elements are scarce, making Browns Range strategically relevant to Western magnet manufacturers and defence supply chains.
What is Northern Minerals’ development timeline for Browns Range?
As of early 2026, Northern Minerals is advancing feasibility work toward a potential commercial-scale operation. A final investment decision has not been announced. Key milestones required before construction include completion of a bankable feasibility study, project financing, and execution of a binding offtake agreement with a downstream HREE processor or end-user.
