The Mozambique rare earth sector gained significant Western backing in February 2026 when the US Trade and Development Agency (USTDA) committed a $1.875 million grant to fund the pre-feasibility study for the Monte Muambe project in Tete Province — the most advanced rare earth development on Mozambican soil. The agreement positions Monte Muambe explicitly as a Western supply chain asset, with no Chinese offtake arrangements in place.
As of April 2026, Mozambique has no operating rare earth mine. The country’s critical minerals profile has been built on coal, natural gas, graphite, and titanium mineral sands. Monte Muambe represents the first credible attempt to add rare earth elements to that list.
Mozambique Rare Earth Geology — Monte Muambe Carbonatite
Monte Muambe is a carbonatite-hosted REE deposit located in Moatize District, Tete Province, northwestern Mozambique. The carbonatite intrusion hosts mineralisation over 260 metres of strike, 230 metres of width, and an average thickness of 46 metres — geometry suited to open-pit extraction.
The maiden mineral resource estimate stands at 13.6 million tonnes at 2.42% total rare earth oxide (TREO). Target elements are neodymium (Nd), praseodymium (Pr), dysprosium (Dy), and terbium (Tb) — the four magnet rare earths that drive demand from EV motors, wind turbine generators, and defence systems. Co-products include fluorspar (1.63 million tonnes at 19% fluorite grade) and identified gallium, adding optionality to the project economics.
The deposit is developed by Altona Rare Earths PLC, a London-listed junior, through its Mozambican subsidiary Monte Muambe Mining Ltda (MMM), established in Maputo in 2019. MMM is majority-owned by Altona; the remaining interest is held by Mozambican partners Pedro Jeremais Manjate and Rogerio Paulo Samo-Gudo.
For context on current market values for the target elements, see the neodymium price tracker and dysprosium price tracker.
Monte Muambe — Scoping Study Economics and Project Status
A scoping study completed in October 2023 outlined the following headline economics: post-tax NPV of $283.3 million at an 8% discount rate, post-tax IRR of 25%, and a payback period of 2.5 years from first production. Life-of-mine EBITDA is projected at $1.67 billion over an 18-year mine life. These are Class 5 estimates — the least precise in the feasibility hierarchy — and are subject to material revision at pre-feasibility and definitive feasibility stage.
The proposed production target is 15,000 tonnes per year of mixed rare earth carbonate (MREC). The process route moves from open-pit mining through comminution and flotation at a beneficiation plant, then into a hydrometallurgical plant using weak acid gangue leach, REE leaching, and purification to produce MREC. Capital expenditure is estimated at $276.3 million at scoping level. Logistics rely on road transport from Tete Province to the Port of Beira for export.
No pre-feasibility study has been published as of April 2026. No definitive feasibility study exists. No final investment decision has been made and no construction timeline has been set. The USTDA grant — with proposals from US engineering firms due by 4 May 2026 — marks the beginning of the pre-feasibility phase, not its conclusion.
US Government Backing and Mozambique Rare Earth Strategy
The USTDA agreement, signed 27 February 2026, funds the pre-feasibility study through a grant to Monte Muambe Mining Ltda. The study will be carried out by a US firm selected through an RFP process. Its objective is to de-risk the metallurgy and process engineering and evaluate the technical, economic, and financial viability of producing Nd, Pr, Dy, and Tb at commercial scale.
Thomas R. Hardy, USTDA Deputy Director, stated that “securing access to rare earths is essential for America’s defense industrial base and our technological edge.” MMM Director Cedric Simonet described the grant as “a powerful external validation of the Monte Muambe project’s strategic quality.” The project has no Chinese offtake and is explicitly framed as a contribution to Western rare earth supply chain security — a posture consistent with the broader supply chain risks driving US critical minerals policy.
The USTDA’s involvement in Monte Muambe sits within a wider US push to secure African critical mineral supply. The same strategic logic has driven US backing for the Lobito Corridor rail infrastructure project across the DRC, Zambia, and Angola. In Mozambique, USTDA activity extends beyond rare earths to energy and infrastructure development.
Elsewhere in Mozambique, MRG Metals (ASX-listed) has submitted licence applications for exploration areas in Sofala Province, with early-stage sampling work indicating REE presence. No resource estimate has been confirmed for the Sofala discovery; it remains at exploration sampling stage and should not be treated as a development-ready project. Its relevance is as a signal of broader industry interest in Mozambique’s REE geology beyond a single deposit.
Mozambique Rare Earth Outlook
The honest near-term picture for Mozambique rare earth development is one of early-stage promise rather than imminent production. Completion of the pre-feasibility study is the immediate milestone; a definitive feasibility study and final investment decision would follow, likely placing any production several years away at minimum. The pace depends on metallurgical results from the PFS, financing conditions, and market prices for magnet rare earths at the time of FID.
Tete Province offers a meaningful infrastructure advantage: the province is Mozambique’s established mining heartland, with coal extraction infrastructure and road access to the Port of Beira already in place. Monte Muambe’s location is geographically distant from the Cabo Delgado instability that has affected Mozambique’s northern gas fields — a distinction relevant to project risk assessment.
Benchmark Mineral Intelligence has included Mozambique among eight African projects expected to contribute to 9% of global REE supply by 2029. At pre-feasibility stage, Monte Muambe’s contribution to that timeline remains aspirational rather than confirmed.

Does Mozambique have rare earth deposits?
Yes. The Monte Muambe carbonatite in Tete Province holds a maiden mineral resource of 13.6 million tonnes at 2.42% TREO, targeting neodymium, praseodymium, dysprosium, and terbium. MRG Metals has also identified early-stage REE mineralisation in Sofala Province, though no resource estimate has been confirmed there.
What is the Monte Muambe rare earth project?
Monte Muambe is a carbonatite-hosted REE deposit in Moatize District, Tete Province, developed by London-listed Altona Rare Earths PLC through its Mozambican subsidiary. A 2023 scoping study outlined a post-tax NPV of $283.3 million and a production target of 15,000 tonnes per year of mixed rare earth carbonate over an 18-year mine life. The project is at pre-feasibility stage as of 2026.
Who is backing Mozambique’s rare earth development?
The US Trade and Development Agency (USTDA) signed a $1.875 million grant agreement in February 2026 to fund the Monte Muambe pre-feasibility study, to be carried out by a US engineering firm. Altona Rare Earths PLC is the London-listed project developer; there are no Chinese offtake arrangements in place.
When will Mozambique start producing rare earths?
No production date has been set. As of April 2026, Monte Muambe is at pre-feasibility stage with no published PFS, no definitive feasibility study, and no final investment decision. Production remains several years away at minimum, subject to metallurgical results, financing, and market conditions at FID.
Where is Monte Muambe located in Mozambique?
Monte Muambe is in Moatize District, Tete Province, northwestern Mozambique — the same province as the country’s established coal mining operations. Road access to the Port of Beira is in place. The project is geographically separate from the Cabo Delgado instability affecting Mozambique’s northern gas fields.
