CENTURY LITHIUM FILES TECHNICAL REPORT ON THE FEASIBILITY STUDY FOR THE ANGEL ISLAND LITHIUM PROJECT, NEVADA

MWN-AI** Summary

Century Lithium Corp. has filed a comprehensive technical report concerning the feasibility study of its wholly-owned Angel Island Lithium Project located in Nevada. This report, effective January 3, 2026, is designed to enhance the company's disclosure efforts following its earlier news release from February 23, 2026. The study was prepared by leading mining and engineering firms and complies with National Instrument 43-101 (NI 43-101).

The feasibility study outlines a robust economic framework for the Angel Island Project, highlighting an after-tax Net Present Value (NPV) of $4.01 billion and an Internal Rate of Return (IRR) of 27.4%, based on lithium carbonate priced at $24,000 per tonne. The project boasts a substantial long-term mine life exceeding 60 years, supported by significant proven and probable reserves of lithium. With an integrated processing system that includes hydrochloric acid leaching and Direct Lithium Extraction (DLE), the operation is anticipated to produce about 26,500 tonnes annually of battery-grade lithium carbonate.

Moreover, the financial analysis indicates that the project will not only generate substantial lithium carbonate but also produce sodium hydroxide, which can reduce operational costs significantly. Phase 1 of the project is expected to require an initial capital investment of approximately $997 million, subsequently expanding operations in Phase 2 with an additional $660 million investment. Average operational costs are estimated at $22.45 per tonne of mill feed, which translates to around $4,389 per tonne of lithium carbonate.

Currently, Century Lithium is navigating the permit process for the project and aims to position itself as a key player in the burgeoning electric vehicle and battery storage markets. The company's developments align with growing global demand for lithium amid an accelerated shift toward sustainable energy solutions.

MWN-AI** Analysis

Century Lithium Corp.'s recent filing of the feasibility study for the Angel Island Lithium Project underscores a pivotal moment for potential investors and stakeholders. The report reveals robust economic metrics, showcasing a staggering after-tax Net Present Value (NPV) of $4.01 billion at an 8% discount rate and an Internal Rate of Return (IRR) of 27.4%, based on lithium carbonate prices of $24,000 per tonne. These figures are particularly attractive, suggesting that the project could yield substantial returns even in volatile market conditions.

The Angel Island project is strategically positioned in Clayton Valley, home to one of the largest known sedimentary lithium deposits in the United States. With proven and probable reserves exceeding 1.7 million tonnes of lithium carbonate equivalent, the potential for long-term production is significant. The feasibility study indicates a projected mine life of over 60 years, with an anticipated average production capacity of 26,500 tonnes annually. This longevity can provide stability in supply for battery manufacturers, aligning well with the relentless growth in the electric vehicle (EV) and renewable energy sectors.

The integration of innovative processing techniques, including Direct Lithium Extraction (DLE) and chlor-alkali processing, not only enhances operational efficiency but also potentially lowers overall production costs. The project is expected to generate a co-product, sodium hydroxide, which will further bolster revenue streams and mitigate the financial impact of rising operational expenses.

However, while the data appears promising, potential investors should remain cautious. The capital costs for both phases of development are substantial, with initial Phase 1 estimates at nearly $997 million and an additional $660 million for Phase 2. The permitting process and market dynamics for lithium can also pose risks. Given these elements, investors are encouraged to conduct thorough due diligence, analyzing both macroeconomic trends and the nuances of Century Lithium's operational strategies, before making investment decisions.

(TSXV: LCE) (OTCQX: CYDVF) (Frankfurt: C1Z) ("Century Lithium" or "the Company") is pleased to announce the filing of the report for the Company's 100%-owned Angel Island Lithium Project ("Angel Island", a.k.a. "Clayton Valley"), "UPDATED NI 43-101 TECHNICAL REPORT ON THE FEASIBILITY STUDY OF THE CLAYTON VALLEY LITHIUM PROJECT Esmeralda County, Nevada, USA", with effective date January 3, 2026 ("Feasibility Study" or "Report"), to support the disclosure in the Company's news release dated February 23, 2026. The Report was prepared in accordance with National Instrument 43-101 (NI 43-101) by Mineral Property Development ("MPDI"), Global Resource Engineering, Ltd. ("GRE") and SRK Incorporated ("SRK").

All currency amounts in this news release are presented in US dollars.

The Feasibility Study incorporates the results of continued metallurgical testing, engineering optimization, refinement of the mine plan, and updated capital and operating cost estimates for Angel Island. Using a base case price of $24,000/tonne ("t") of lithium carbonate, Angel Island's estimated after-tax cash flow has a 27.4% Internal Rate of Return ("IRR") and a $4.01 billion Net Present Value ("NPV") at an 8% discount rate.

Feasibility Study Highlights

  • After-tax NPV (8% discount rate) of $4.01 billion based on price assumptions of $24,000/t for lithium carbonate and $750/dry metric tonne for sodium hydroxide
  • After-tax IRR of 27.4%
  •  Integrated patent-pending processing flowsheet, incorporating hydrochloric acid leaching, Direct Lithium Extraction ("DLE"), chlor-alkali processing, and on-site production of battery-grade lithium carbonate, validated through four years of pilot plant operations in Nevada
  • Large, long-life US-based lithium development project, with Proven and Probable Reserves supporting a mine life exceeding 60 years
  • Economic analysis based on a 40-year production schedule, with a life-of-mine average production of approximately 26,500 tonnes per annum ("tpa") of battery-grade lithium carbonate
  • Phase 1 throughput of 7,500 tonnes per day ("tpd"), expanding to 15,000 tpd in Year 5 (Phase 2)

Capital and Operating Costs

  • Phase 1 estimated capital cost of $997 million
  • Phase 2 estimated expansion capital of $660 million
  • Average estimated operating cost of $22.45/t of mill feed, equivalent to $4,389 per tonne of lithium carbonate
  • Project revenues from surplus sodium hydroxide equivalent to $5,393/t of lithium carbonate produced. When treated as a co-product credit, this would result in a net operating cost below zero

Mineral Resource and Reserve

  • Measured and Indicated Mineral Resources of 1.138 billion t at 966 parts per million ("ppm") lithium, containing 5.852 million t lithium carbonate equivalent ("LCE")
  • Proven and Probable Mineral Reserves of 287.65 million t at 1,149 ppm lithium, containing 1.759 million t LCE
