Century Lithium Corp. ( TSXV: LCE) (OTCQX: CYDVF) (Frankfurt: C1Z) ( Century Lithium or the Business) is delighted to report screening outcomes at Saltworks Technologies, Inc. (Saltworks) in Richmond Canada and extra production of high-purity lithium carbonate (Li 2 CO 3) utilizing item services from the Business’s Lithium Extraction Center (Pilot Plant) in Amargosa Valley, Nevada U.S.A.. The services evaluated at Saltworks were originated from seeping of claystone from the Business’s 100%- owned Clayton Valley Lithium Task (Task) in Nevada; and processed at the Pilot Plant by means of direct lithium extraction (DLE) to produce an intermediate focused lithium option (DLE eluent).
“It is extremely favorable to see consistency in our high-purity, 99.87%, lithium carbonate item grades from our Pilot Plant this year” specified Expense Willoughby , President, and CEO of Century Lithium “The emphasize however, is the nearly five-fold boost in lithium grade in the focused lithium option produced at the Pilot Plant. This was accomplished through partnership with Koch Innovation Solutions and their Li-Pro TM system, and its combination into Century Lithium‘s chloride-based leaching procedure.”
Emphasizes
- Repetitive production of high-purity (99.87%) battery-grade lithium carbonate
- Enhanced lithium concentrations in DLE eluent
- Minimized volume of option in downstream treatment and recycling
- Prospective to remove evaporation from the post DLE procedure flowsheet
- Active screening underway to more enhance DLE eluent grade
Lithium Carbonate Assay Outcomes
Saltworks has actually as soon as again produced battery-grade lithium carbonate (Li 2 CO 3 ) from the DLE eluent produced at the Pilot Plant. The table listed below is a contrast of Saltworks’ 2023 outcomes for Li 2 CO 3 , DLE eluent Batch 2, with the formerly reported arise from DLE eluent Batch 1 (see Might 25 , 2023 press release ). Likewise revealed are the constituent levels for battery grade Li 2 CO 3, as released by 2 significant manufacturers. The assays outcomes were completed by Saltworks and separately assayed by SGS Canada, Inc. These outcomes reveal consistency in structure of both the DLE eluent produced by the Pilot Plant previously in the year and the resulting Li 2 CO 3 item produced by Saltworks, accomplishing 99.871% material versus 99.875% reported formerly.

Lithium in DLE Eluent
As just recently reported (see August 9, 2023 press release ), Century Lithium teamed up with Koch Innovation Solutions (KTS), a Koch Engineered Solutions’ (KES) business, and incorporated KTS’ Li-Pro TM system into the DLE phase of the Pilot Plant. This work has actually increased the grades of the DLE eluent (intermediate lithium item option) a number of fold. These modifications are detailed in the table listed below, as reported by analyses from Saltworks.

Notes: DLE eluent for Batch 1 and 2 utilized to produce Li 2 CO 3 mentioned above. |
|||||
Batches 1, 2 and 3 are DLE eluents produced throughout the very first quarter of 2023. Li 2 CO 3 production was performed to conclusion in batches 1 and 2 however the processing of Batch 3 was postponed due to its resemblance to batches 1 and 2 and the enhancements seen in the grades of batches 4 and 5. These enhancements in lithium grade from 1,430 parts per million (ppm) to 6,780 ppm, boost in the ratio of lithium to overall liquified solids (TDS) from 0.018 to 0.085, and decrease in salt from 25,850 ppm to 8,220 ppm all accompanied the intro of KTS’ Li-Pro TM system into the DLE phase of the Business’s Pilot Plant.
Ramifications for Lithium Carbonate Production
The boost in lithium (Li) grade and the Li: TDS ratio has favorable ramifications for the size and expenses of the lithium carbonate production part of the lithium extraction procedure at the Task. Within the Saltworks flowsheet, these greater worths correspond to a lower volume of option to be dealt with and a proportional reduction in the quantity of water that should be gotten rid of (vaporized) prior to lithium carbonate rainfall. This will likewise impact the recycled services within the lithium carbonate production phase by decreasing the volume of services relocated this phase and other seeping locations of the processing plant.
The info originated from the Pilot Plant, consisting of the test arises from the mix of Century Lithium‘s DLE procedure and KTS’ Li-Pro TM system, and current element modifications at the Saltworks lab, is additional to the Expediency Research Study for the task. The style basis for the Expediency Research study was developed 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 rainfall. Deal with KTS at the DLE phase at the Pilot Plant has actually seen initial, internally assayed, lithium option grades of over 8,000 ppm in the DLE eluent. Work is continuing within the DLE location to more boost lithium grades in option, producing the scope to lower option volumes and the prospective to remove a significant evaporation action from the procedure flowsheet. As a supplement to the Expediency Research Study, the Business is pursuing these prospective expense and size cost savings with Saltworks.
Progressing
Deal With the Expediency Research study continued throughout the 6 months ended June 30, 2023 , with more than 20,000 expert hours used up given that its beginning. Following invoice of preliminary worths from our experts, Wood PLC and thyssenkrupp nucera, the Business is carrying out internal evaluations to evaluate optimization and expense decrease chances; work which is underway. In June 2023 , the Business engaged Kiewit Industrial Group in Lone Tree, Colorado to help with the evaluation of task styles and quotes with attention to website advancement, product and supply expenses, and building approaches. One optimization chance, decreasing or removing making use of thickeners for tailings separation at the same time setup, was executed and is under trial at the Pilot Plant.
The Business’s partnership with KTS is underway, using KTS’ Li-Pro TM devices in the DLE area of the Pilot Plant, where lithium is selectively recuperated from the leach option while unhealthy aspects are declined. Checking with KTS is anticipated to continue through the 3 rd quarter while KTS gathers info to prepare an engineering style and expense quote for a full-blown release of Li-Pro TM system which will supplement the Business’s Expediency Research study.
