Direct Lithium Extraction: Pilot Test Results
The Company, through its ownership in Hub City Lithium, has successfully completed a large-scale pilot using the ILiAD DLE Platform developed by EnergySource Minerals ("ESM"), a privately held process technology company focusing on DLE in North America. The pilot, which processed 87,000 litres of brine from the Viewfield project area, successfully recovered 8,300 litres of concentrated eluent with an average lithium concentration of 1,430 mg/L (representing a 7.5x concentration from the feed brine provided). An average lithium recovery of >
Production of Battery Grade Lithium Carbonate
Hub City Lithium has confirmed successful production of
Saltworks Technologies Inc. ("Saltworks"), a global leader in designing and delivering industrial wastewater treatment and lithium refinement solutions, saw brine sourced from wells in Hub City Lithium's Viewfield project area refined into battery grade lithium carbonate. The Viewfield lithium-containing brine represents the highest concentrations of lithium discovered in Canada to date with minimal pretreatment requirements.
After direct lithium extraction, the eluent was refined into battery-grade chemicals at Saltworks' headquarters in British Columbia. This work was executed with Saltworks' proprietary concentrating, refining, and converting technology and expert technical team, employing novel technology that lowers the cost and greenhouse gas impact of lithium chemical production.
This project tested and de-risked the end-to-end flow sheet, resulting in multiple samples of battery-grade lithium carbonate, which have been analyzed and validated by an independent 3rd party laboratory. The captured data enables the acceleration of a full-scale plant design and dispatch. Details below.

Viewfield Field Pilot
Hub City Lithium is currently undergoing a Treatability Study ("Study") with Koch Technology Solutions ("KTS") to test 1,000 litres of feed brine from the Viewfield project area. The Study is in preparation for a DLE field pilot (one of the first in Saskatchewan) on the Hub City Lithium well that previously tested 258 mg/L of Lithium. The pilot, scheduled to begin in Q1 2024, will treat Viewfield brine and convert it into a highly concentrated lithium chloride eluent. It's expected to run for 3 to 4 months and will operate 24/7, processing approximately 6,500 - 9,000 litres of feed brine per day.
Viewfield Acreage Purchase
At the November 2023 Crown Public Offering Hub City Lithium increased its land holdings in its Viewfield project area by 4,065 net acres (
Hub City Lithium currently holds greater than 196,000 net acres (79,300 net hectares) of Subsurface Dispositions and numerous strategic wellbores in Southern Saskatchewan.
Preliminary Economic Assessment Update
The PEA, which focuses on a Phase 1 development at Viewfield, is nearing completion with anticipated final approvals and release in January 2024. The release delay can be attributed to capital and operating cost adjustments within the PEA, a result of the ongoing Viewfield brine testing and processing with multiple DLE vendors.
