The package includes:

| Senior debt facility | Up to $500M |
| Government purchase commitment | At least $300M |
| Total | $1.55B |
The investment is tied to Serra Verde's Pela Ema mine in Brazil, which produces four strategically important rare earths: neodymium, praseodymium, dysprosium and terbium.
US SIIE is expected to purchase 100% of Serra Verde's Phase 1 production under a long-term offtake agreement.
Why these four elements matter
Neodymium and praseodymium are key inputs for high-performance permanent magnets. Dysprosium and terbium improve their performance at high temperatures.
These magnets are used in:
- missiles and guidance systems;
- fighter aircraft;
- submarines;
- satellites and drones;
- electric vehicles;
- wind turbines;
- industrial motors.
The project gives the U.S. access to a non-Asian source of materials critical to both defense and advanced manufacturing.
The U.S. is guaranteeing demand, not just funding supply
The structure goes beyond a conventional mining investment. The government has committed to purchase at least $300 million of rare-earth products over five years, while the associated offtake agreement includes take-or-pay provisions and price floors.
This reduces two major risks for rare-earth producers: volatile prices and uncertain demand.
The Serra Verde project has also received a $565 million financing commitment from the U.S. International Development Finance Corporation to support expansion and optimization of the Pela Ema operation. Combined, the measures give Washington influence over both production and where the material ultimately enters the supply chain.
The strategic objective
The U.S. does not need every rare-earth mine to be located domestically. It needs reliable access to material that can feed processing and magnet manufacturing outside China's supply chain.
Brazil provides the upstream production. U.S. investment and purchase commitments secure the output. Domestic processing and magnet capacity provide the downstream link.
The $750 million investment is therefore primarily a supply-security transaction: Washington is using government capital to lock in long-term access to neodymium, praseodymium, dysprosium and terbium before expanding the U.S. mine-to-magnet chain.
