REA Heavy Rare Earths Exploration Expands in the US and Brazil

Rare Earths Americas

REA heavy rare earths exploration accelerates after a $16mn funding round. The company will develop high-grade assets in the US and Brazil. REA heavy rare earths exploration targets dysprosium and terbium supply growth. Grades at Georgia’s Foothills reach 41.3% TREO with rich monazite sands. Therefore, REA heavy rare earths exploration strengthens non-China supply optionality for magnets.

Portfolio spans US monazite and Brazil ionic clays

REA controls four projects across two countries. Foothills in Georgia hosts surface monazite with Dy and Tb. Brazil adds Alpha and Constellation ionic clays in Bahia and Minas Gerais. These clays total about 1bn tonnes of mineralization. All projects also contain neodymium and praseodymium. Homer in Goiás targets carbonatites with REE and niobium potential. As a result, REA balances near-surface sands with scalable clay resources.

Strategic value for dysprosium, terbium and NdPr supply chains

Heavy rare earths enable high-coercivity NdFeB magnets. Therefore, Dy and Tb access remains strategically critical. Ionic clays can enable simpler leaching routes at scale. Meanwhile, Foothills offers high grades and quick sampling cycles. NdPr credits improve project economics. Additionally, Homer’s niobium upside diversifies revenue. Offtake, permitting, and processing partners will define timelines.

The Metalnomist Commentary

REA’s mix of monazite sands and ionic clays hedges geology and processing risk. Success will hinge on low-impurity circuits and responsible leach management. Watch pilot metallurgy and early offtake signals through 2026.
