CHILEAN COBALT CORP. ENTERS OFFTAKE ARRANGEMENT WITH

GLENCORE ON LA COBALTERA AND EL COFRE PROJECTS

BERWYN, PA – (November 13, 2025) – Chilean Cobalt Corp. (OTCQB: COBA) (“Chilean Cobalt” or the “Company”) is pleased to announce that it has entered into an offtake arrangement, pursuant to a Deed of Undertaking, with a wholly-owned subsidiary of Glencore plc (LSE: GLEN) (together, with its subsidiaries, “Glencore”). The Company will provide Glencore with an irrevocable and exclusive right to purchase up to 100% of cobalt and/or copper containing products at and/or derived from the Company’s La Cobaltera and El Cofre projects in northern Chile, as well as any other materials, metals and/or byproducts produced and/or derived from the La Cobaltera and El Cofre projects (the “Materials”), for the life of mine.

Both parties anticipate that of any Materials sold to Glencore in the future, the majority of the cobalt and copper intermediate product stream will be shipped into the United States (“US”) for processing and refining.

“This marks a significant milestone for Chilean Cobalt as we advance the La Cobaltera and El Cofre projects and work to establish an Americas-focused cobalt supply chain,” said Duncan T. Blount, Chairman and CEO of Chilean Cobalt. “We believe that working with Glencore, one of the world’s leading producers and marketers of cobalt and copper, will satisfy a key condition precedent as we pursue strategic project financing, and positions us to accelerate project development, while supporting the growing demand for secure and responsibly sourced critical minerals.”

In addition, Glencore is expected to provide strategic support for development of Chilean Cobalt’s La Cobaltera Phase 1 cobalt-copper project, and to collaborate on new initiatives aimed at developing US-based processing and refining capabilities for metal products and/or battery materials.

Through this relationship, Chilean Cobalt will leverage Glencore’s global expertise and extensive network as one of the world’s leading producers and marketers of cobalt, with established extraction and processing operations worldwide.
