Feasibility study expected shortly. Century’sClayton Valley lithium project is among the most advanced pre-permitted lithium projects in North America. In2023, the company focused on pilot plant operations with the results of a project feasibility study (FS) expected to be released within the next couple of weeks. The full report will be available approximately 45 days later. While production is expected to be consistent with the earlier preliminary feasibility study (PFS), we expect a phased approach to full scale production.
Feasibility study expectations. While weexpect the feasibility study to reflect higher capital and operating costs, the economics may improve relative to the PFS due to several factors. These include: 1) a higher base case pricing assumption for lithium carbonate equivalent that could be in the range of US$22,000 to US$30,000 per tonne compared to US$9,500 per tonne used in the PFS, 2) a potential economic benefit from the by-product sales of sodium hydroxide, 3) the leaching process will be based on using hydrochloric acid instead of sulfuric acid, and 4) the project will likely incorporate lower cost renewable power.

By-product sales of sodium hydroxide. Clayton Valley uses locally sourced sodium chloride brine which is treated by electrolysis in a chlor-alkali plant to produce the leaching and neutralization reagents needed for the process on-site. In the chlor-alkali plant, sodium hydroxide is produced as a by-product. Pilot plant testing has generated a significant surplus of sodium hydroxide which may be sold as a by-product. The western United States is largely dependent on imports of sodium hydroxide for water treatment and other industrial uses. A market study, to be incorporated in the feasibility study, will reflect the potential for revenue from sodium hydroxide sales.

December 11, 2023 – Vancouver, Canada – Century Lithium Corp. (TSXV:LCE) (OTCQX: CYDVF) (Frankfurt: C1Z) (“Century Lithium” or “the Company”) is pleased to report progress and further developments at its Lithium Extraction Facility (“Pilot Plant”) in Amargosa Valley, Nevada.
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-ProTM 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.

December 6, 2023 – Vancouver, Canada – Century Lithium Corp. (TSXV:LCE) (OTCQX: CYDVF) (Frankfurt: C1Z) (“Century Lithium” or “the Company”) is pleased to provide an update on its ongoing Feasibility Study for its Clayton Valley Lithium Project (“Project”) in Clayton Valley, Nevada, and has commenced a market study on sodium hydroxide as a soluble by-product.
Highlights
Feasibility Study continues with work on options for a phased approach to production
Market study on sodium hydroxide as salable by-product to be included in the Feasibility Study
Throughout the year, Century Lithium remained focused on the development of its Clayton Valley Lithium Project. The work included ongoing testing of lithium extraction at the Pilot Plant and continuing work on the Feasibility Study for the Project, with reviews of capital and operating cost estimates with consultants Wood PLC, Global Resource Engineers, thyssenkrupp nucera USA, Saltworks Technologies Inc., and WSP USA Environment & Infrastructure Inc. This comprehensive study covers all areas of the lithium extraction process from shallow surface mining of lithium-bearing clay to on-site production of battery-grade lithium carbonate. Target production for the study follows that of the project’s earlier Pre-Feasibility Study, which was based on a mill feed of 15,000 tonnes per day and average annual output of 27,000 tonnes per year of lithium carbonate equivalent.
To date, the Company has worked with its Feasibility Study team to revise and update estimates based on optimization. Given volatility in the lithium market, the Company is examining a phased approach to full scale production to provide prospective parties with a lower risk alternative in financing. The Company is working with its consultants to determine viable phases and underlying schedules.
The scope of the Project is multi-faceted in its approach to processing, and includes clay leaching and filtration, ion-exchange based direct lithium extraction (“DLE”) from leach solutions, and the production of battery-grade lithium carbonate from the DLE product solutions via concentration, purification, and precipitation. The process is driven by locally sourced sodium chloride brine (salt solution) which is treated by electrolysis in a chlor-alkali plant to produce all the leaching and neutralization reagents required for the process on-site.
In the operation of the chlor-alkali plant, the neutralizing reagent generated is sodium hydroxide, also commonly known as lye, caustic soda, or simply caustic. In the plant, sodium hydroxide is produced as a by-product of the generation of the leaching reagent, hydrochloric acid, in an amount that is slightly greater than the production of hydrochloric acid. The acid and base are both produced in liquid form at concentrations in the range of 30-37%, The hydrochloric acid is fully utilized in the leaching process. Sodium hydroxide is used at various points in the operation for neutralization and removal of impurities.
Pilot plant testing has shown a significant amount of the sodium hydroxide will be surplus to the production process and therefore available as a by-product for potential sale. The western United States is largely dependent on imports of this essential chemical for water treatment and other industrial uses. A market study, to be incorporated in the Feasibility Study, recognizes the potential for revenue from sodium hydroxide sales, tapping into the need for a domestic supply of sodium hydroxide.
In order to properly evaluate the alternatives and incorporate economic benefits of by-product sales, described above, the Company anticipates completion of the Feasibility Study in Q1 2024.

Near-term weakness presents an opportunity. Lithium stocks have been weighed down by a decline in lithium spot prices this year driven mainly by factors in China. The recent price of battery grade lithium carbonate was ~US$23,300 per tonne. We think it presents an opportunity for longer-term investors based on favorable intermediate and long-term lithium fundamentals supported by growth in the North American electric vehicle market. While commodity spot prices tend to be volatile, long-term supply contracts will likely account for market volume growth as electric vehicle industry participants seek to secure their own lithium sources.
North American lithium projects have gained traction. With critical minerals supplies subject to geopolitical risk, lithium projects in North America benefit from a variety of funding options as battery manufacturers and car makers seek to secure supplies to de-risk their own long-term objectives. General Motors’ investment and offtake agreement with Lithium Americas to advance the Thacker Pass lithium project in Nevada validates the commercial potential of similar projects. Another example is the U.S. Dept. of Energy’s commitment to lend up to US$700 million to develop Ioneer’s Rhyolite Ridge project in Nevada coupled with US$490 million of conditional financing from Sibanye-Stillwater and binding offtake agreements with Ford, Toyota/Panasonic, and EcoPro.

Collaboration with Koch. Century Lithium is collaborating with Koch Technology Solutions (KTS) in the application of Koch’s proprietary Li-Pro equipment for the direct lithium extraction (DLE) portion of Century’s pilot plant where lithium is recovered from leach solution. Work continues within the DLE section to further increase lithium grades in solution and potentially eliminate a major evaporation step from the process.
Li-Pro leads to significant improvements. With the introduction of KTS’ Li-Pro system into the DLE stage of the pilot plant, the grades of the intermediate lithium solution produced at the pilot plant have increased while unwanted elements have been reduced. Lithium grades improved from 1,430 parts per million lithium to 6,780 parts per million lithium resulting in an increase in the ratio of lithium to total dissolved solids from 0.018 to 0.085 and a reduction in sodium from 25,580 parts per million sodium to 8,220 parts per million sodium. Preliminary internally assayed lithium solution grades have exceeded 8,000 parts per million lithium.

August 21, 2023 – Vancouver, Canada – Century Lithium Corp. (TSXV:LCE) (OTCQX: CYDVF) (Frankfurt: C1Z) (Century Lithium or the Company) is pleased to report testing results at Saltworks Technologies, Inc. (Saltworks) in Richmond, Canada, and additional production of high-purity lithium carbonate (Li2CO3) using product solutions from the Company’s Lithium Extraction Facility (Pilot Plant) in Amargosa Valley, Nevada, USA. The solutions tested at Saltworks were derived from leaching of claystone from the Company’s 100%-owned Clayton Valley Lithium Project (Project) in Nevada; and processed at the Pilot Plant via direct lithium extraction (DLE) to produce an intermediate concentrated lithium solution (DLE eluent).
“It is very positive to see consistency in our high-purity, 99.87%, lithium carbonate product grades from our Pilot Plant this year” stated Bill Willoughby, President, and CEO of Century Lithium. “The highlight though, is the almost five-fold increase in lithium grade in the concentrated lithium solution generated at the Pilot Plant. This was achieved through collaboration with Koch Technology Solutions and their Li-ProTM system, and its integration into Century Lithium’s chloride-based leaching process.”
Highlights
Repeated production of high-purity (99.87%) battery-grade lithium carbonate
Improved lithium concentrations in DLE eluent
Reduced volume of solution in downstream treatment and recycling
Potential to eliminate evaporation from the post DLE process flowsheet
Active testing underway to further improve DLE eluent grade
Lithium Carbonate Assay Results
Saltworks has once again produced battery-grade lithium carbonate (Li2CO3) from the DLE eluent produced at the Pilot Plant. The table below is a comparison of Saltworks’ 2023 results for Li2CO3, DLE eluent Batch 2, with the previously reported results from DLE eluent Batch 1 (see May 25, 2023 news release). Also shown are the constituent levels for battery grade Li2CO3, as published by two major producers. The assays results were finalized by Saltworks and independently assayed by SGS Canada, Inc. These results show consistency in composition of both the DLE eluent produced by the Pilot Plant earlier in the year and the resulting Li2CO3 product produced by Saltworks, achieving 99.871% content versus 99.875% reported previously.

Batches 1, 2 and 3 are DLE eluents produced during the first quarter of 2023. Li2CO3 production was carried out to completion in batches 1 and 2 but the processing of Batch 3 was put on hold due to its similarity to batches 1 and 2 and the improvements seen in the grades of batches 4 and 5. These improvements in lithium grade from 1,430 parts per million (ppm) to 6,780 ppm, increase in the ratio of lithium to total dissolved solids (TDS) from 0.018 to 0.085, and reduction in sodium from 25,850 ppm to 8,220 ppm all occurred with the introduction of KTS’ Li-ProTM system into the DLE stage of the Company’s Pilot Plant.
Implications for Lithium Carbonate Production
The increase in lithium (Li) grade and the Li:TDS ratio has positive implications for the size and costs of the lithium carbonate production portion of the lithium extraction process at the Project. Within the Saltworks flowsheet, these higher values equate to a lower volume of solution to be treated and a proportionate decrease in the amount of water that must be removed (evaporated) prior to lithium carbonate precipitation. This will also affect the recycled solutions within the lithium carbonate production stage by reducing the volume of solutions moved in this stage and other leaching areas of the processing plant.
The information derived from the Pilot Plant, including the test results from the combination of Century Lithium’s DLE process and KTS’ Li-ProTM system, and recent component changes at the Saltworks laboratory, is supplemental to the Feasibility Study for the project. The design basis for the Feasibility Study was established at a Li:TDS ratio of 0.02.
The Saltworks flowsheet targets a lithium grade of 10,000 to 20,000 ppm (10-20 g/L) for precipitation. Work with KTS at the DLE stage at the Pilot Plant has seen preliminary, internally assayed, lithium solution grades of over 8,000 ppm in the DLE eluent. Work is continuing within the DLE area to further increase lithium grades in solution, creating the scope to reduce solution volumes and the potential to eliminate a major evaporation step from the process flowsheet. As a supplement to the Feasibility Study, the Company is pursuing these potential cost and size savings with Saltworks.
Moving Forward
Work on the Feasibility Study continued throughout the six months ended June 30, 2023, with more than 20,000 consultant hours expended since its commencement. Following receipt of initial values from our consultants, Wood PLC and thyssenkrupp nucera, the Company is conducting internal reviews to assess optimization and cost reduction opportunities; work which is underway. In June 2023, the Company engaged Kiewit Industrial Group in Lone Tree, Colorado to assist with the review of project designs and estimates with attention to site development, material and supply costs, and construction methods. One optimization opportunity, reducing or eliminating the use of thickeners for tailings separation in the process configuration, was implemented and is under trial at the Pilot Plant.
The Company’s collaboration with KTS is underway, utilizing KTS’ Li-ProTM equipment in the DLE section of the Pilot Plant, where lithium is selectively recovered from the leach solution while deleterious elements are rejected. Testing with KTS is expected to continue through the 3rd quarter while KTS collects information to prepare an engineering design and cost estimate for a full-scale deployment of Li-ProTM system which will supplement the Company’s Feasibility Study.

Successful collaboration with Koch. Century Lithium is collaborating with Koch Technology Solutions (KTS) in the application of Koch’s proprietary Li-Pro direct lithium extraction (DLE) process. In April, Century installed equipment from KTS and has operated the equipment at the pilot plant with significantly improved results.
Li-Pro leads to a higher grade lithium concentrate. With the integration of KTS’s DLE process, the grades of the intermediate lithium solution produced at the pilot plant have increased to the highest levels to date with an average grade of 7.5 grams per liter or 7,500 parts per million lithium. Lithium concentrations are four times higher than previously produced and unwanted elements in the final solution have been reduced. The process has resulted in the complete removal of calcium and magnesium along with significant reductions of sodium and potassium.
