Aclara Resources is a rare-earth elements company with mining projects in Brazil and Chile and mineral processing projects in the United States. It is a publicly owned company whose major stakes are held by Hochschild Mining (55.9%) and CAP (10.1%).[2] It is listed on the Toronto Stock Exchange.[3]
The mines in Brazil and Chile are planned to supply a rare-earth separator plant that is under construction as of March 2026 in Louisiana in the US.[2] In 2025 the company claimed that by 2028 it expected to supply more than 75% of the US demand of dysprosium (Dy) and terbium (Tb).
The company traces its origins to 2018 when Hochschild Mining purchased 6.2% of the Chilean company BioLantánidos which was owned by the Minería Activa-administered FIP Lantanidos fund of LarrainVial.[7]
