CENTURY LITHIUM FILES TECHNICAL REPORT ON THE FEASIBILITY STUDY FOR THE ANGEL ISLAND LITHIUM PROJECT, NEVADA
Nevada Claystone Giant Validates Economics with $4 Billion NPV and Negative Net Operating Costs

The most recent news (March 09, 2026) confirms the filing of a definitive Feasibility Study (FS) Technical Report for the Angel Island Lithium Project in Nevada. This follows the February 23, 2026, summary announcement. Key highlights include an after-tax NPV of $4.01 billion (8% discount) and an IRR of 27.4%. The study outlines a 40-year production profile averaging 26,500 tonnes per annum (tpa) of battery-grade lithium carbonate. Crucially, the project utilizes a patent-pending chloride leaching and DLE flowsheet. Operating costs are estimated at $4,389/t LCE, but the company highlights that surplus sodium hydroxide (caustic soda) production could generate revenue of $5,393/t LCE, potentially driving net operating costs below zero.
The impact is Material - Positive. While the market was aware of the project's scale, the updated FS provides several "game-changing" economic refinements: - Economic Robustness: A $4B NPV is massive relative to the company’s current market cap (approx. 60x multiple), suggesting significant undervaluation if the project reaches FID. - Byproduct Synergy: The ability to sell surplus sodium hydroxide is a strategic masterstroke that hedges against lithium price volatility by potentially covering all cash operating costs. - Permitting De-risking: The news follows the project's inclusion in the federal FAST-41 program, which provides a coordinated and transparent timeline for NEPA compliance, a major hurdle for Nevada claystone projects. - Validation of Tech: Moving from "demonstration" to "feasibility" with a 91.6% DLE recovery rate (reported in 2025) validates the proprietary chloride-leach process over traditional sulfuric acid methods.
Century Lithium (formerly Cypress Development) owns 100% of the Angel Island Lithium Project in Clayton Valley, Nevada. It is a sedimentary (claystone) deposit adjacent to Albemarle’s Silver Peak mine. It is one of the largest lithium resources in the U.S., with 5.85M tonnes LCE in Measured & Indicated categories.
