Highlights

• Further process improvements implemented at the Pilot Plant, resulting in lithium grades consistently exceeding 14 grams/liter in the intermediate solutions produced (up from 7.5 grams/liter reported in August 2023)
• Pilot Plant tests ongoing completing 23 months of safe operation
• Work with Koch Technology Solutions LLC (“KTS”) on direct lithium extraction (“DLE”) is ongoing; delivering repeatable results and exceeding expectations
• KTS to complete commercial design of a DLE installation for the Project in January 2024

On August 9, 2023, the Company reported achieving an increase of lithium grades in the intermediate solutions produced at the Pilot Plant to the highest levels to date, with an average grade of 7.5 grams/liter lithium. This increase in concentration was attributed to the integration of Koch Technology Solutions Li-Pro^TM equipment into the DLE area.  In mid-August, the Company added an osmotically assisted reverse osmosis (“OARO”) unit downstream of the DLE area. (Description of the process can be found at the Company’s technology partner Saltworks’ website: OARO—Saltworks Announces Osmotically Assisted RO Tech | Saltworks Technologies). With the OARO unit in operation at the Pilot Plant, Century has consistently achieved lithium grades exceeding 14 grams/liter in its intermediate solutions, accompanied by significantly reduced levels of impurities.

Century’s collaboration with KTS continued to produce exceptional results within the DLE area of the Pilot Plant. With nearly 3,000 operating cycles of the equipment completed since its installation in April 2023, results have exceeded target levels for both lithium extraction and rejection of impurities from leach solutions. With these positive results, the Company anticipates KTS completing its commercial design of a DLE installation for the Project in January 2024. 

Century’s team continues to innovate and improve its process flowsheet for the Project through testing equipment, reagents, and alternate configurations of its flowsheet at the Pilot Plant. This work will continue into the coming year as the Pilot Plant generates data to support and further de-risk the Project and addresses recommendations identified during the Feasibility Study.
