August 6, 2024 – Vancouver, Canada – Century Lithium Corp. (TSXV:LCE) (OTCQX: CYDVF) (Frankfurt: C1Z) (Century Lithium or the Company) is pleased to report the successful addition of a lithium carbonate stage at the Company’s Lithium Extraction Facility (Pilot Plant) in Amargosa Valley, Nevada, USA, part of the Company’s 100%-owned Angel Island Mine (the Project). Prior to this addition, concentrated lithium solutions from the Pilot Plant were treated by Saltworks Inc. at their facility in Richmond B.C. where samples of battery quality lithium carbonate were produced. During the first days of startup of the lithium carbonate stage, Century’s team at the Pilot Plant successfully treated 200 liters of concentrated lithium solution and produced 20 kg of high-grade lithium carbonate onsite.
“At this point in time, the ability to make lithium carbonate at our Pilot Plant is an important step forward, in line with recommendations from our recently completed Feasibility Study” commented President and CEO Bill Willoughby. “The drop in lithium prices over the last year has taken a toll on the share price of all lithium companies. Despite the downturn, domestic production is still key to the security of supply in the U.S. While it is becoming well known that a vast amount of lithium is contained within the claystone deposits of Nevada, the benefit in unlocking these resources is the ability to produce a battery quality lithium product onsite and thereby reducing or eliminating the need for downstream processing.”
The Company continues work at the Pilot Plant, utilizing the Company’s patent-pending process for chloride leaching combined with Direct Lithium Extraction (DLE) to generate data as the Company works to identify further technological breakthroughs to make the extraction of lithium from clay more economic. Adding the lithium carbonate stage at the Pilot Plant is one of the recommendations made in the Feasibility Study, not only to further demonstrate that battery quality lithium carbonate can be made, but to better understand and minimize the recycle streams from the DLE stage through to final product in the process. With the assistance of engineers from Hargrove Engineers and Constructors, Century’s team configured equipment to run 40-liter batches of concentrated lithium solution though precipitation, washing and drying steps. Final assays on the lithium carbonate are pending.

July 23, 2024 – Vancouver, Canada – Century Lithium Corp. (TSXV:LCE) (OTCQX: CYDVF) (Frankfurt: C1Z)
Century Lithium (or the Company) announces it has changed the name of its 100%-owned Clayton Valley Lithium Project in Nevada, USA to the Angel Island Mine (the Project). In April 2024, the Company announced a positive Feasibility Study for the Project, making it one of the few advanced lithium projects being developed in the United States. As the Company now continues to work towards permitting the Project, regulators encouraged a name change for clarity in the permitting process. The Angel Island name distinguishes it from other mining and energy projects in the area by using the name of a topographical feature from the Project.
ABOUT ANGEL ISLAND
Angel Island is named for the ridge of older metavolcanic and clastic rocks bordering the west side of Century’s lithium clay deposit. The name itself dates to the 1800’s, one of three landforms in Clayton Valley named for islands in San Francisco Bay (Alcatraz and Goat islands being the other two). Of the three landforms, Angel Island is the largest, rising to a height 400 meters above the valley floor. Its presence on the east side of the valley, separating Century’s lithium clay deposit from the lithium brine operation of Albemarle Corp., is owed to uplift along a major northeast trending normal fault located along the western base of the ridge. Although not directly related to the formation of Century’s deposit, uplift of Angel Island along this fault was responsible for elevating the clay deposits east of the fault and bringing them to the surface where they are now accessible for mining. The harder rocks in the ridge also likely acted as a physical barrier protecting Century’s lithium clay deposit from erosion.

The effective date of the Mineral Reserve Estimate is December 15, 2022. The QP for the estimate is Ms. Terre Lane, MMSA, an employee of GRE and independent of Century. The Mineral Reserve estimate was prepared in accordance with CIM) Definition Standards (CIM, 2014) and the CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines (CIM, 2019). Mineral Reserves are reported within the final pit design at a mining cut-off of 900 ppm. The cut-off grade considers a mine operating cost of $1.98/t, a process operating cost of $14.27/t milled, a G&A cost of $0.65/t milled, process recovery of 83% and a long-term lithium carbonate price of $20,000/t. The cut-off of 900 ppm is an elevated cut-off selected for the mine production schedule as the elevated cutoff is 4.5 times higher than the break-even cut-off grade. Mineral Reserve figures have been rounded. One tonne of lithium = 5.323 tonnes lithium carbonate. Mineral Resources are inclusive of Mineral Reserves.
PROCESS METALLURGY & CHLOR-ALKALI PLANT
Metallurgical testing through 2020 focused on using sulfuric acid (H2SO4) to extract lithium from the clay. In late 2020, testing shifted to hydrochloric acid (HCl) for its improved compatibility with the deposit’s chemistry. These benefits included higher lithium extractions, lower reagent consumptions, significantly better filtration of solids, and the ability to utilize certain DLE technologies in the recovery and concentration of lithium from the leach solutions.
A key component of the Project with chloride-based leaching is a chlor-alkali plant. The chlor-alkali plant provides the ability to produce the key reagents HCl and NaOH on-site from the electrolysis of a sodium chloride (NaCl) solution. A chlor-alkali plant represents a greater capital investment relative to that of a sulfuric acid plant but has important environmental and economic benefits for the sustainability of the Project. These benefits include replacing the purchase and transportation of sulfur with regionally sourced salt, and a reduction in emissions and the physical footprint of the operation with dryer, non-sulfate tailings.
Additionally, the chlor-alkali plant will generate significant quantities of NaOH surplus to the Project’s operational needs and therefore available for sale. The chlor-alkali plant will utilize modern electrochemical cell technology thereby producing membrane grade sodium hydroxide without the energy consumption and environmental problems of older technologies. The surplus amounts of NaOH are inherent to the operation of the plant and the sales represent a significant offset to the Project’s operating costs.
PILOT PLANT
In 2021, Century Lithium constructed a Pilot Plant in Nevada to leach one tonne per day of lithium clay and produce a high-grade lithium chloride solution which is processed off-site at Saltworks Technologies, Inc. (Saltworks), at their Richmond, British Columbia processing plant to make battery-quality Li2CO3. To maximize lithium recovery, the Company purchased the license rights and pilot-stage equipment to DLE an ion-exchange-based process and incorporated it into the Pilot Plant. The DLE license is held in perpetuity and royalty free by the Project.
Throughout its Pilot Plant program, the Company has sought improvement in its process methods. The Company obtained a provisional patent in 2023 with the U.S. Patent and Trademark Office, U.S. Department of Commerce. The provisional patent is titled System and Method for Extracting Lithium from Clay and Other Materials in a Chloride Solution Using Individualized Pretreatments. The patent pending process encompasses the Company’s flowsheet and protects its methods of leaching lithium-bearing solids and handling solutions, precipitates, and residues.
LITHIUM EXTRACTION, RECOVERY & Li2CO3 PRODUCTION
A lithium recovery of 78% is used in the Feasibility Study, based on the data collected in over two years of operations at the Pilot Pant.
Feed material grades averaged 1,100 ppm
Leach solution samples varied from 200 to 320 ppm Li
Lithium extractions averaged 88% and varied from 80 to 95%
DLE lithium recoveries were typically above 90%
10% of the lithium in solution is retained in the moisture remaining in the tailings
Extraction rates do not account for losses downstream and are only indicative of the potential overall recovery. Work at the Pilot Plant continues to focus on reducing losses of lithium to tailings. A small loss of lithium from processing the DLE product solutions into Li2CO3, and the recycling of process solutions to the DLE and leach areas is anticipated.
During 2022 and 2023, Saltworks processed the DLE product solutions from the Pilot Plant and made battery-quality Li2CO3 at greater than 99.5% purity. Modifications at the Pilot Plant in mid-2023 increased lithium solution grades to over 14 grams per liter which simplified the flowsheet and eliminated the evaporation stage for production of Li2CO3.
PRODUCTION PLAN
The Project’s production plan comprises three equal phases of production rate increases, Phase 1 and Phase 2 production rates are maintained over five years each and Phase 3 is maintained for 30 years. This approach was selected to reduce capital exposure and risk by dividing the Project’s production schedule into realistic phases of construction and equipment installation. The plan fully utilizes the Project’s Mineral Reserve.
Phase 1 includes all work required to implement the Initial Project Plan including all necessary mining and processing infrastructure. The Phase 2 cost estimate focuses on an expansion within the footprint of Phase 1. Phase 3 development includes an additional processing plant and facilities not built in the previous phases and allows for a fourth phase of expansion.
LITHIUM CARBONATE AND SODIUM HYDROXIDE SALES PRICES
A price of $24,000/t of Li2CO3 is used in the Feasibility Study as the Project base case. This price is selected as a conservative mid-point between current market prices which are under $20,000/t Li2CO3 and forecast prices obtained from Benchmark Mineral Intelligence which are in the range of $23,000 to $39,000/t Li2CO3 during Phase 1 and $29,000 to $31,000/t Li2CO3 thereafter (Benchmark Mineral Intelligence, Lithium Forecast Q1 2024). The sales price is free on board (FOB) the Project site for battery quality Li2CO3.
NaOH is a product of the chlor-alkali process and a sales price of $600/dmt FOB the Project is used in the Feasibility Study as the Project base case. Based on the material mass balance, it is expected that surplus NaOH will be available for sale at rates of 120,000 to 360,000 dmt per annum, depending on Project Phase. This price is based on a February 2023 market study by Global Exchange and Trading, Inc. where it was determined the Project’s surplus NaOH can be readily sold in the western U.S. which currently relies heavily on imports arriving at west coast ports.
CAPITAL COST ESTIMATE
The basis for the capital cost estimate follows AACE Class 3 for feasibility studies. Contributors to the estimates are GRE (mining), Wood (process plant and infrastructure), ThyssenKrupp Nucera (chlor-alkali plant) and Century Lithium (property information and owners’ costs). The capital cost estimates by phase are summarized as follows.

The Phase 2 capital costs represent the expansion of the process facilities and infrastructure established in Phase 1. The Phase 3 capital costs support an additional processing plant and facilities not built in the previous phases. In the Project schedule, a 2-year period is allocated for the time to construct and commission each phase.
Sustaining capital over the life of the Project is estimated at $315 million for tailings facility expansion and equipment replacements. These costs are in addition to the expansion capital costs shown above.

Lithium carbonate sales are the average over each Phase including ramp up to the stated production rate. Gross sales are revenues from Li2CO3 and NaOH sales are before operating costs and after royalty. Before-tax Cash Flow is gross sales minus operating costs. Taxes are applied at federal, state and county rates after allowances for amortization, depletion, and depreciation only. Possible tax credits under the U.S. Inflation Reduction Act or other programs are not included.
The Project base case generates a 17.1% after-tax IRR and NPV-8% of $3.01 billion. These results are sensitive to changes in operating assumptions including the sales price of Li2CO3.
At 75% of the base case, or $18,000/t LCE, the after-tax NPV@ 8% is $1.52 billion, and the after-tax IRR is 12.9%.
At 125% of the base case, or $30,000/t LCE, the after-tax NPV@ 8% is $4.47 billion, and the after-tax IRR is 20.9%.
For every $1,000/t change in the price of lithium carbonate, the after-tax NPV@8% changes by about $250 million.

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.

An enormous lithium deposit estimated to hold up to 40 million metric tons has recently been discovered in the United States underneath an ancient supervolcano straddling the Nevada-Oregon border. This lithium trove, the largest known supply in the world, could provide major opportunities for lithium companies and boost renewable energy efforts as demand for lithium batteries is projected to skyrocket.
Lithium, an extremely light metallic element, is an essential component of rechargeable lithium-ion batteries used in electric vehicles, grid storage, smartphones, laptops and other key technologies. With electric vehicle adoption accelerating globally and increasing need for batteries to store solar and wind energy, lithium is becoming integral to a clean energy future.
For lithium companies, this huge deposit represents a potentially massive new source of supply to power growth. Lithium exploration and mining companies will likely ramp up operations in the region to benefit from burgeoning demand. Those able to cost-effectively extract lithium from the volcanic crater could be poised to reap sizable revenues.
Access to substantial lithium resources located within the US rather than relying heavily on imports could also help enhance energy security as the country moves away from fossil fuels. Domestic supply could additionally stabilize lithium prices and support US-based jobs.
The lithium deposit was uncovered within Oregon’s McDermitt Caldera, the remnants of an ancient supervolcano that exploded around 16 million years ago. With lithium demand expected to expand fivefold or more by 2030, this huge supply could be a game-changer, diversifying and elevating global lithium sources to meet increasing battery requirements.
For lithium companies and renewable energy companies alike, this deposit represents a monumental opportunity. Responsible extraction will be key to unlocking the full potential of this transformative mineral discovery.
Take moment to look at companies Lithium Bank and Century Lithium who are focused on exploration, development, and production of 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.

August 9, 2023 – Vancouver, Canada – Century Lithium Corp. (TSXV:LCE) (OTCQX: CYDVF) (Frankfurt: C1Z) (Century Lithium or the Company) is pleased to report successful progress in its collaboration with Koch Technology Solutions (KTS), a Koch Engineered Solutions (KES) company. As reported previously (see April 17, 2023, news release) Century Lithium and KTS are working together on the application of KTS’s Li-ProTM system at Century’s Lithium Extraction Facility (Pilot Plant) in Amargosa Valley, Nevada, USA.
“Century Lithium is delighted to see the progress made in our collaboration with Koch Technology Solutions” stated Bill Willoughby, President, and CEO of Century Lithium. “Our team, with KTS’s input has successfully incorporated and operated the equipment at our Pilot Plant with significantly improved results.”
Since October 2021, Century Lithium has been continuously testing the extraction of lithium from the claystone found at its 100%-owned Clayton Valley Lithium Project (Project) in Nevada utilizing a chloride-based leaching process. Testing of the Li-ProTM system was conducted to evaluate potential improvements in the direct lithium extraction (DLE) area of the Pilot Plant.
Adam Sackett, President of Koch Technology Solutions, added, “The steady state results generated onsite with the Koch Technology Solutions Li-Pro™ Direct Lithium Extraction process has hit all our key milestones for the Century pilot program. We are excited to move towards engineering and executing a Li-Pro™ installation with commercial process guarantees.”
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/liter (g/l) (7,500 parts per million) lithium. These lithium concentrations are four times higher than previously generated, with sodium concentrations almost an order of magnitude lower.
Highlights To Date
Successful installation and operation of Koch’s Li-ProTM DLE process
Li-ProTM plant achieved steady state using Century Lithium’s chloride leaching process
Manufacture intermediate solutions with lithium grades of 7 to 8 g/l concentrations with average lithium to sodium ratios of 0.9 to 1.1
No observed degradation of media or accumulation of deleterious elements
Operational Results
Since the installation of KTS’s DLE equipment, Century Lithium has focused on improvements related to the operational aspects of the Pilot Plant and adjustments to the final flowsheet. These improvements were well supported through the development and incorporation of KTS’s DLE equipment at the Pilot Plant.
Century Lithium, with the support of KTS, has identified techniques to improve lithium recovery within the DLE area while minimizing deleterious elements in the final solutions. Collaboration between Century Lithium and Koch staff is very productive, generating ideas and changes that have resulted in the complete removal of calcium and magnesium, and marked reduction of sodium and potassium in the product solutions.

Feasibility Study Update
A Feasibility Study on the Project (Study) began in February 2022, with the engagement of Wood PLC as independent lead author. The Study has progressed well, with contributions from Global Resource Engineers, WSP USA Environment & Infrastructure Inc., and thyssenkrupp nucera, and with the support of Century Lithium’s personnel and consultants.
Major areas of the Study are completed and estimates for capital and operating cost estimates received, including those for the chlor-alkali plant portion of the Project. Wood is in the process of consolidating the estimates and reviewing them with Century, along with evaluating further optimization and opportunities for cost reductions. This optimization work will extend beyond the previously estimated mid-year completion date for the Study. The Company continues to focus on the Study and will provide updates in due course.
At the Pilot Plant, the collaboration of Century Lithium and Koch Technology Solutions (KTS) is underway testing the KTS Li-Pro™ process for DLE. Century Lithium personnel are working closely with KTS in the testing program, which has now completed its third 7-day cycle of operation. Thus far, the KTS process equipment has operated exceptionally well, using feed solution from the Pilot Plant, and the Company is very pleased with its performance.
