America’s Next Rare-Earth Bet Starts With Just $4.84 Million

The U.S. has committed $4.84 million to support a proposed $150 million rare-earth project in Madagascar. The early funding could help unlock a new supply chain for manufacturers across America and Europe.

A relatively small U.S. investment could help unlock a much larger rare-earth project in Madagascar.

The U.S. International Development Finance Corporation has committed up to $4.84 million to Harena Rare Earths’ Ampasindava project. The funding will support early work including laboratory testing, environmental programmes and the operation of a pilot plant.

Compared with the project’s estimated $150 million cost, the initial commitment is modest. Its importance lies in what could follow.

If the early development work is successful, Harena may become eligible for substantially larger financing as the project moves towards construction. That could help create a new source of rare earths for manufacturers in the U.S. and Europe.

Rare earths are a group of specialised materials used in permanent magnets for electric vehicles, electronics, wind turbines and advanced industrial equipment. Demand is rising, but building a reliable supply chain requires far more than opening a mine. The materials must also be separated, refined and converted into components manufacturers can use.

Ampasindava could provide an important starting point.

The project contains neodymium, praseodymium, dysprosium and terbium, four valuable rare earths used in high-performance magnets. Harena expects it could eventually produce around 4,000 tonnes of rare-earth oxides annually, including approximately 1,700 tonnes of high-value magnet materials.

Production is targeted for mid-2028, although several obstacles remain.

Harena still needs an exploitation permit, full construction financing and agreements covering where its output will be processed. The company is considering potential partnerships with U.S. and European groups, including MP Materials, USA Rare Earth and Solvay.

Those relationships could prove just as important as the mine itself. Extracting rare earths in Madagascar would create a new source of supply, but processing them elsewhere would be necessary to build a complete chain connecting the deposit with Western manufacturers.

For investors, the project shows how government support can help reduce the risks surrounding early-stage mining developments. Public funding for testing and environmental work can make it easier for private capital to assess whether a project is technically and commercially viable.

However, the $4.84 million commitment should not be mistaken for a guarantee. Mining projects frequently face permitting delays, rising construction costs and difficulties securing long-term buyers. Ampasindava must still prove that it can move from a promising deposit to a profitable operation.

The opportunity is nevertheless significant. If Harena secures the necessary approvals, partners and financing, a relatively small initial commitment could help establish a new rare-earth supply route stretching from Madagascar to processing facilities and manufacturers across the U.S. and Europe.

The mine itself may be located in Africa, but its potential value lies in the wider supply chain it could help create.
