Vancouver – September 13, 2026 -- Century Lithium Corp. has submitted its Mine Plan of Operations and Nevada Reclamation Permit Application for the 100%-owned Angel Island lithium project in Esmeralda County, Nevada, starting the federal environmental review clock on one of the largest known sedimentary lithium deposits in the United States.
Company files 5,379-acre plan with U.S. Bureau of Land Management
The Plan of Operations was submitted September 3, 2026, to the BLM's Battle Mountain District, Tonopah Field Office, by wholly owned subsidiary Cypress Holdings (Nevada), Ltd. The document, prepared under 43 CFR Subpart 3809 and Nevada's NAC 519A regulations, will serve as the basis for the BLM's National Environmental Policy Act analysis. The Project Area covers 5,379 acres of BLM-administered public land, with approximately 2,364 acres of proposed disturbance.
Staged output ramps from 8,300 to 16,500 tons per day
Angel Island, located in Clayton Valley roughly six miles east of Silver Peak, will mine lithium-bearing claystones via six shallow open pits with no drilling or blasting required. Initial production is set at approximately 8,300 tons per day for the first four years, scaling to a maximum of 16,500 tpd from years five through 40. Ore will be processed on-site through agitated tank leaching, direct lithium extraction and crystallization into battery-grade lithium carbonate, using a closed-loop water system.
Chlor-alkali plant to supply reagents and sell surplus sodium hydroxide
A chlor-alkali plant will generate hydrochloric acid and sodium hydroxide for the process circuit, with surplus sodium hydroxide sold into the open market. Support infrastructure includes two waste rock storage facilities, two low-grade ore stockpiles, a dry-stack tailings facility, and a warehouse, office, shop and laboratory complex.
Project requires up to 106 MW of grid power and a 12-inch water pipeline
Grid power needs are set at 53 MW in Phase 1, rising to 106 MW in Phase 2, with the Company's preferred connection tying into the new Esmeralda substation on the NV Energy Greenlink West corridor. Process water will be sourced from an existing water right roughly 11 miles south of the site, delivered via a buried 12-inch pipeline across BLM land. The operation is expected to employ approximately 275 full-time workers, with a construction peak of about 450.
Federal Permitting Dashboard targets February 2028 completion
Angel Island holds Transparency Project status under the FAST-41 program, with the BLM as lead agency and progress tracked on the federal Permitting Dashboard, which currently lists an estimated environmental review completion date of February 4, 2028. The BLM will now conduct a 30-day completeness review of the Plan before a third-party NEPA contractor begins environmental analysis, developing Supplemental Information and Environmental Reports ahead of an Administrative Environmental Impact Statement, public scoping, and an eventual Record of Decision.
President and CEO Bill Willoughby called the filing "a substantial milestone" that reflects multiple years of baseline data collection, engineering and agency coordination, with Century Lithium's focus now shifting to supporting the BLM and NEPA contractor toward final project approval.
In parallel, the Company is advancing Nevada state and local permitting, including preparation of its Water Pollution Control Permit application, alongside continued metallurgical test work on the Angel Island flowsheet.
