CENTURY LITHIUM FILES MINE PLAN OF OPERATIONS FOR ANGEL ISLAND LITHIUM PROJECT IN NEVADA
Century Lithium (CYDVF) has submitted a Mine Plan of Operations and Nevada Reclamation Permit Application for its 100%-owned Angel Island lithium project in Esmeralda County, Nevada, to the U.S. Bureau of Land Management on September 3, 2026.
Rhea-AI Summary
Century Lithium (CYDVF) has submitted a Mine Plan of Operations and Nevada Reclamation Permit Application for its 100%-owned Angel Island lithium project in Esmeralda County, Nevada, to the U.S. Bureau of Land Management on September 3, 2026.
The Plan defines a shallow surface mine over six pit phases with no drilling or blasting anticipated, covering about 2,364 acres of disturbance within a 5,379-acre project area. Operations are outlined in two stages: an initial production rate of approximately 8,300 tpd for the first four years, increasing to up to 16,500 tpd from years five through forty. On-site processing is designed to produce battery-grade lithium carbonate using agitated tank leaching, direct lithium extraction, and a closed-loop water circuit, supported by a chlor-alkali plant that also yields saleable sodium hydroxide.
Planned support infrastructure includes waste rock and low-grade stockpiles, a dry-stack tailings facility, and grid power of 53 MW in Phase 1 and 106 MW in Phase 2, with water supplied via an 11-mile pipeline. The project, designated a FAST-41 Transparency Project, follows a federal permitting schedule currently targeting completion of environmental review and permitting by February 4, 2028, subject to adjustment as reviews proceed.

"The submission of the Mine Plan of Operations for Angel Island is a substantial milestone for Century Lithium," said Bill Willoughby, President and CEO of Century Lithium. "It defines the Project the BLM will analyze, starts the clock on the environmental review, and reflects multiple years of baseline data collection, engineering, and coordination with the agencies. With the PoO completed, our focus turns to supporting the BLM and the third-party NEPA contractor toward a final Project approval through a Record of Decision."
The PoO describes the mine, the processing plant, and the supporting infrastructure, and defines the process for reclamation of the land when mining is complete, and was submitted by the Company's wholly owned subsidiary, Cypress Holdings (
The Angel Island Lithium Project
Angel Island is an advanced-stage, sedimentary lithium project located in Clayton Valley,
Key elements of the proposed operation, as set out in the PoO, include (see 2026FS):
- Shallow Surface Mine. Lithium-bearing claystones allow mining in six pit phases with minimal overburden and low strip ratio. No drilling or blasting is anticipated; the ore will be ripped, loaded, and hauled to the processing facility.
- Staged Growth. A two-phase development, with an initial production rate of approximately 8,300 tons per day ("tpd") for the first four years of operation, increasing to a maximum of up to 16,500 tpd in years five through 40.
- On-site Processing to Battery-grade Lithium Carbonate. Processing by agitated tank leaching, solid/liquid separation, Direct Lithium Extraction ("DLE"), and crystallization to produce battery-grade lithium carbonate. The process circuit is closed-loop and designed to operate with recycled water.
- Salt-based Reagents. A chlor-alkali plant will produce hydrochloric acid and sodium hydroxide, both required by the process circuit, with surplus sodium hydroxide to be sold into the open market. Sodium hydroxide is a product of the processing circuit and is not derived from material mined from the Project.
- Support Facilities. Included are two waste rock storage facilities, two low-grade ore stockpiles, a dry-stack tailings storage facility, heavy- and light-vehicle roads, and a warehouse, office, shop, and laboratory.
- Grid Power. 53 MW in Phase 1 and 106 MW in Phase 2 are to be supplied by a transmission-voltage connection, with the Company's preferred route tying into the new
Esmeralda substation on the NV Energy Greenlink West corridor. - Water Supply. Process make-up water is to be obtained under the Company's existing water rights from a well approximately 11 miles south of the Project and delivered to site via a buried 12-inch pipeline on BLM land, for which biological and cultural baseline surveys were completed.
- Workforce. A workforce of approximately 275 full-time personnel is anticipated during operations, with a temporary peak of approximately 450 during construction.
Next Steps and Permitting Schedule
Angel Island is a Transparency Project under the Federal Permitting Improvement Steering Council's FAST-41 program, with the BLM as lead agency. FAST-41 status provides coordinated federal oversight, publicly tracked milestones, and schedule transparency through the Permitting Dashboard for Federal Infrastructure Projects. The Permitting Dashboard currently shows an estimated completion date for environmental review and permitting of February 4, 2028. As with any federal schedule, the timetable may be adjusted as the review proceeds, and updates are posted on the Permitting Dashboard.
With the PoO submitted, the BLM will complete a 30-day regulatory review of the Plan for completeness and adequacy. Once the Plan is deemed complete, the third-party NEPA contractor will begin environmental analysis of the Project and will develop the Supplemental Information Report ("SIR") and the Supplemental Environmental Reports ("SERs") to support the NEPA document. Once the SIR and SERs are completed, the Administrative Environmental Impact Statement ("EIS") can be prepared, after which the BLM is expected to publish a Notice of Intent in the Federal Register and initiate public scoping, ultimately leading to a Record of Decision ("ROD"). The anticipated sequence of milestones is summarized below.
Milestone | Target | Status / Notes |
PoO and Nevada Reclamation Permit Application submitted | September 3, 2026 | Completed |
BLM completeness review | Q4 2026 | In Progress |
Notice of Intent published in Federal Register initiating public scoping period | Q2 2027 | Estimated |
Additional baseline data collection | Q2 2027 | If required |
Notice of Availability for EIS, ROD, and PoO published in Federal Register | Q1 2028 | Anticipated |
Note: Target dates are anticipated dates based on the schedule prepared for the Project by the Company, BLM, and the third-party contractor. |
In parallel with the federal process, the Company continues to advance state and local permitting in
