Century Lithium's Technical Breakthrough on Angel Island

In an exciting development for the lithium industry, Century Lithium Corp. has released a comprehensive update regarding its wholly owned Angel Island lithium project, situated near Silver Peak, Nevada. This recent announcement highlights significant advancements achieved through their Demonstration Plant located in Amargosa Valley, Nevada. As the demand for lithium grows, particularly in the electric vehicle sector, Century Lithium is positioning itself at the forefront of innovation in lithium extraction technology.

Bill Willoughby, Century Lithium’s President and CEO, emphasized that the company is dedicated to enhancing its extraction processes. The Demonstration Plant has allowed the team to test and refine their technologies vigorously. Notably, a collaboration with Amalgamated Research, LLC (ARi) has yielded promising results that surpassed initial expectations in various tests related to the Direct Lithium Extraction (DLE) process.

Advancements Achieved in Testing

The pilot testing conducted from November 2024 to January 2025 has produced remarkable results that could drastically improve the operational efficiency of the Angel Island project. The tests revealed a lithium feed concentration of 328 milligrams per liter, achieving an impressive 91.6% lithium recovery rate. Furthermore, the eluate grade was raised to 575 mg/L, boasting a low sodium-lithium (NaLi) ratio of 0.61. These figures are crucial as they indicate that the extraction process is not only efficient but also points toward potential cost reductions in capital and operating expenditures at Angel Island.

Additional testing demonstrated further technical progress, notably increasing the lithium concentration in the eluate to between 12 to 14 grams per liter using specialized membranes during the concentration phase following DLE. Continuing operations in the lithium carbonate circuit have also shown outstanding results, achieving a remarkable purity level of 99.87% in lithium carbonate (Li2CO3) samples.

These lithium carbonate samples are currently being evaluated by third-party entities for their effectiveness in producing lithium iron phosphate (LFP) batteries. LFP batteries are recognized for their high energy density and long lifespan, making them ideal for renewable energy storage systems and long-range electric vehicle applications.

Future Directions and Innovations

Moreover, Century Lithium is in the process of exploring the thermal pretreatment of clay from Angel Island, which holds the potential to significantly lessen the use of hydrochloric acid during the leaching stage of manufacturing. This innovative approach stands to further streamline the overall process and enhance sustainability—an increasingly vital aspect of modern mining operations.

The development at Angel Island is not merely about improving current methods. It is also about laying the groundwork for the future. With stringent efforts to innovate, the company is navigating the complex landscape of lithium production while adhering to environmental and safety standards. This balance is integral, as market demand for sustainable energy solutions accelerates.

With a life-of-mine average production estimate of 34,000 tonnes of lithium carbonate annually across a projected mine life of 40 years, the Angel Island project could emerge as a major contender for lithium supply in the U.S. as the country seeks to bolster its domestic energy solutions.

Implementing advanced technologies and refining extraction methods, Century Lithium Corp. is fast-tracking the development of the Angel Island project. As they continue to progress, stakeholders and potential investors are likely to keep a close eye on upcoming developments that could reshape the lithium landscape in North America.
