BERWYN, PA / ACCESS Newswire / June 26, 2026 / Chilean Cobalt Corp. (OTCQB:COBA) ("Chilean Cobalt" or the "Company") is pleased to provide an update on exploration, metallurgical development, engineering, permitting, and strategic partnership initiatives at the NeoRe Rare Earth Project ("NeoRe" or the "Project") in southern Chile, as the Company continues to advance an integrated development strategy focused on establishing a scalable Western supply chain for critical rare earth elements ("REE").

Through project operator, NeoRe SpA ("NeoRe"), the Company continues to advance resource definition, pilot-scale processing, engineering, permitting, and commercial development activities in support of further deployment of the Project's first Modular Extraction Plant ("MEP-1").

A significant milestone was recently achieved with the initiation of pilot plant commissioning activities and the successful production of NeoRe's first rare earth carbonate concentrate. This milestone represents an important step in validating the Project's metallurgical process flowsheet and advancing downstream processing capabilities within Chile.

In parallel, NeoRe is advancing its own rare earth separation pilot plant in Chile's Biobío region. The facility is designed to process heavy rare earth concentrate already being produced across NeoRe's project locations in the region. The NeoRe technical team has previously demonstrated the ability to produce high-purity rare earth concentrate and successfully separated REEs using solvent extraction ("SX") technology.
