• After-tax NPV (using 8% discount rate) of $4.01 billion based on price assumptions of $24,000 per tonne (“/t”) for lithium carbonate (“Li₂CO₃”) and $750/dry metric tonne for Sodium Hydroxide (“NaOH”)
• After-tax internal rate of return (“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 U.S.-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 planned life-of-mine average production of approximately 26,500 tonnes per annum of battery-grade lithium carbonate
• Initial Phase 1 throughput of 7,500 tonnes per day, expanding to 15,000 tpd in Year 5 (Phase 2)
• Average operating cost of $22.45 per tonne of mill feed, equivalent to $4,389 per tonne of lithium carbonate, compared to $8,223 per tonne in the 2024 Study
• 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

 $7 MILLION FINANCING CLOSED 

Century Lithium completed the $7 million brokered offering in less than 24 hours, reflecting strong institutional demand and confidence in both the Company and the long-term potential of the Angel Island project. The offering was led by Alliance Global Partners and consisted entirely of institutional investors.

• March 10: Announced an initial placement of up to $5M at $0.47/unit
• March 11: Upsized to $7M on the back of strong investor demand

Proceeds are directed primarily toward the next phase of technical and permitting work at Angel Island, additional test work to evaluate potential byproducts (including rare earth elements) and improve process performance, with a portion supporting general working capital.

NEXT STEPS

Century Lithium will continue to advance Angel Island toward development through submission of plan of operations, permitting, detailed engineering, and engagement with interested parties as the Project progresses toward a construction decision. Integral to these key steps are:

• Recent appointment of Cormac O’Laoire, PhD to advise the Company in discussions with potential downstream partners and offtake interests. The Company continues to make inroads in Washington DC and Nevada to convey the importance of Angel Island for a secure North American supply chain.
• Further evaluation of the economic potential for rare earth elements (“REE”) recovery at Angel Island.
• Engagement of BMO Capital Markets to assist the Company in its efforts towards securing strategic interests and development funding.
• Addition, in 2025 to the US Federal Permitting Dashboard for FAST-41 transparency status. Inclusion to FAST-41 increases the Project’s exposure to federal agencies and stakeholders to accelerate the permitting process.
