Cerium Project Pipeline

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

Bayan Obo Mine

Northern Rare Earths/Baotou Steel

Production
Country: China Capacity: ~50,000+ tonnes REO/year

Worlds largest rare earth mine producing massive volumes of bastnasite and monazite; cerium is the most abundant output element at ~50% of light REE content

Mt Weld

Lynas Rare Earths

Production (expanding)
Country: Australia Capacity: ~10,500 tonnes REO/year

Highest-grade rare earth deposit globally; cerium oxide is a major product of the LAMP processing facility in Malaysia

Mountain Pass

MP Materials

Production (building downstream)
Country: United States Capacity: ~43,000 tonnes concentrate/year

Sole active US rare earth mine; building Stage II and III processing to produce separated cerium and other rare earth oxides domestically

Government Support and Strategic Initiatives

Recognizing the strategic importance of Cerium, 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, Cerium 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 Cerium projects within the EU and partner nations.

Key Industry Developments

Recent developments affecting the Cerium project landscape:

2010-2011

Chinas rare earth export quota crisis drove cerium oxide prices from ~$5/kg to over $80/kg before crashing back as quotas were lifted and demand destroyed

2015

WTO ruled against Chinas rare earth export quotas; China replaced quotas with resource taxes, stabilizing the market

2019

China threatened to restrict rare earth exports during US-China trade tensions, causing temporary cerium price spike

2023

China imposed export controls on rare earth processing technologies, affecting the ability of Western nations to build independent cerium processing

2024

Cerium oversupply persisted as a challenge for miners; cerium's low value relative to other rare earths made it a drag on project economics for NdPr-focused operations
