Century Lithium produces first LiOH at demo plant

Executive Summary

• Century Lithium Corp. has successfully produced its first batch of high-purity lithium hydroxide at its demonstration plant in Amargosa Valley, Nevada.
• The lithium hydroxide was derived from lithium carbonate sourced from the company’s 100%-owned Angel Island lithium project, marking a significant technical milestone in expanding the product portfolio beyond lithium carbonate.
• The production utilized the company’s patent-pending alkaline leach and direct lithium extraction (DLE) process, followed by conventional liming conversion to achieve 99.5%+ purity.

Key Details

• Production Milestone: First-time production of lithium hydroxide at the Amargosa Valley demonstration plant.
• Feedstock Source: Lithium carbonate derived from the Angel Island lithium project (lithium claystone deposit) near Silver Peak, Nevada.
• Process Technology:
  • Utilized Century Lithium’s patent-pending alkaline leach and direct lithium extraction (DLE) process.
  • Produced on-site in a batch process using conventional liming conversion with calcium hydroxide.
• Product Specifications: High-purity lithium hydroxide with a purity of 99.5% or greater.
• Strategic Context:
  • Demonstrates the ability to supply lithium hydroxide (essential for NMC/NCA batteries) in addition to lithium carbonate (essential for LFP batteries).
  • Positions the Angel Island project as a potential key contributor to U.S. energy independence and domestic battery supply chains.
• Future Process Development: The company is pursuing a direct lithium conversion (DLC) process to produce lithium hydroxide directly from lithium chloride solution, which would bypass the lithium carbonate intermediate stage to simplify operations and reduce energy/operating costs.
• Project Status: Angel Island is in the permitting stage for a three-phase feasibility-level production plan.
• Projected Production: Estimated life-of-mine average of 34,000 tonnes per year of lithium carbonate over a 40-year mine-life.
• Qualified Person: Todd Fayram, MMSA, QP, Senior Vice-President, Metallurgy, approved the technical information.

Notable Quotes

• "The lithium hydroxide samples produced by our team represent another important milestone for the company... By producing high-purity lithium hydroxide, we show that Angel Island can supply another major lithium product for the domestic market." — Bill Willoughby, President and CEO
