Electra Battery Materials Corporation Begins Testing North American Cobalt Feedstock

SEC Filing 6-K (0001171843-25-004894)

Electra Battery Materials Corporation (NASDAQ: ELBM; TSX-V: ELBM) has announced the start of metallurgical testing on cobalt feedstock from two strategic North American sources: the historic Cobalt Camp in Ontario and the Iron Creek cobalt and copper project in Idaho. This initiative aims to strengthen and diversify Electra’s cobalt refinery feedstock pipeline by integrating domestic sources alongside existing global supply partners. The program supports the development of a robust, flexible, and resilient North American critical minerals supply chain. Preliminary results from the North American feedstock program are expected by the end of 2025 and will inform potential front-end flowsheet modifications, such as the addition of a pressure oxidation (POX) circuit. Electra’s in-house laboratory is installing equipment to evaluate these new feedstocks, with bench-scale testing and analytical work to validate and refine proposed flowsheet enhancements. The company’s hydrometallurgical refinery is designed to process cobalt hydroxide feedstock from the Democratic Republic of Congo and convert it into battery-grade cobalt sulfate for use in lithium-ion batteries and energy storage. Electra’s refinery project is backed by a long-term offtake agreement with LG Energy Solution for up to 80% of output over the first five years.
