CENTURY LITHIUM'S ANGEL ISLAND MINE PLAN OF OPERATIONS DEEMED COMPLETE BY BLM, ADVANCING PROJECT TOWARD ENVIRONMENTAL REVIEW

The U.S. Bureau of Land Management (BLM), Battle Mountain District, Tonopah Field Office, has reviewed and determined that the mine plan of operations (PoO) and Nevada reclamation permit application for Century Lithium Corp.'s 100-per-cent-owned Angel Island lithium project in Esmeralda county, Nevada, United States, are complete. The determination advances Angel Island toward environmental review under the National Environmental Policy Act (NEPA).

"The BLM's completeness determination is an important milestone for Angel Island. It confirms that our project is ready to move into the environmental review phase of the process," said Dr. Bill Willoughby, president and chief executive officer of Century Lithium. "We've been focused on finishing the remaining baseline studies and are working closely with the BLM and the third party NEPA contractor as we move toward the environmental analysis part of the process."

BLM completeness determination

In a letter dated Nov. 3, 2026, the BLM notified Century Lithium that it has reviewed the plan and determined it to be complete under 43 CFR Paragraph 3809.411. The plan defines the components of the project and will serve as the basis for the BLM's environmental review and analysis pursuant to the NEPA. Upon completion of the NEPA analyses and the public scoping process, the PoO will be revised as necessary, at which point the BLM can officially approve the PoO.

Next steps toward environmental review

Completion of the remaining baseline studies related to the proposed water supply pipeline route is pending. At this stage, the BLM will issue a letter documenting completion and acceptance of all required baseline studies and reports and will determine the appropriate level of NEPA review for the project, either an environmental assessment or environmental impact statement. Now that the PoO has been deemed complete, the third party NEPA contractor will begin preparation of the supplemental information report (SIR) and the supplemental environmental reports (SERs) to support the NEPA document followed by the environmental analysis of the project. The company will provide updates on the review process and schedule once that determination is made.

Permitting timeline

Angel Island is a transparency project under the Federal Permitting Improvement Steering Council's FAST-41 program, with the BLM serving as lead agency. The permitting dashboard for federal infrastructure projects currently shows a target date of Feb. 4, 2028, for issuance of the record of decision for the project. As with any federal schedule, this timetable may change as the review progresses, and the company will provide updates as key milestones are reached.
