Cerium (Ce)
The most abundant rare earth element at the Guayana Highlands deposit, with an estimated 720,000 tonnes of probable reserves. The workhorse of the catalytic industry, precision optics, and energy storage technologies.
While less glamorous than neodymium, cerium's sheer volume of industrial consumption makes it irreplaceable. Over 70% of global production is concentrated in a single jurisdiction. Downstream processing into high-purity optical-grade oxide can increase per-unit value by 5-10x.
Reserve Valuation
At current oxide prices (~$2/kg for CeO₂), the 720,000 tonnes of probable cerium reserves at the Guayana Highlands REE deposit represent an estimated in-ground value of $1.44 billion USD. Downstream processing into high-purity optical-grade oxide can increase per-unit value by 5-10x.
Strategic Relevance
Cerium is the workhorse of the rare earth elements. While less glamorous than neodymium, its sheer volume of industrial consumption makes it an irreplaceable pillar of multiple value chains. Over 70% of global cerium production is concentrated in a single jurisdiction. The Guayana Highlands deposit offers a hemispheric alternative with 720,000 tonnes of probable reserves — enough to supply decades of Western industrial demand.
