Terbium Project Pipeline

The following projects represent the most significant Terbium operations and development-stage assets worldwide:

Browns Range

Northern Minerals

Pilot
Country: Australia Capacity: ~20-40 tonnes Tb/year planned

One of very few heavy REE projects outside China with significant terbium content in xenotime ore

Government Support and Strategic Initiatives

Recognizing the strategic importance of Terbium, governments in major consuming nations have launched programs to support project development. These include direct financing, loan guarantees, streamlined permitting, and bilateral resource partnerships. As a USGS-listed critical mineral, Terbium projects are eligible for various U.S. government support mechanisms including the Defense Production Act Title III program. EU Critical Raw Materials Act provisions enable fast-track permitting and financing support for Terbium projects within the EU and partner nations.

Key Industry Developments

Recent developments affecting the Terbium project landscape:

2010-2011

Terbium prices surged from ~$500/kg to over $4,500/kg during Chinas rare earth crisis; one of the hardest-hit heavy rare earths

2022

Grain boundary diffusion technology using terbium (alongside dysprosium) gained traction for reducing total heavy REE content in EV magnets

2024

US Navy concerns about Terfenol-D supply chain led to DPA investments in magnetostrictive material production
