LithiumBank Resources has completed bulk brine sampling at its Boardwalk lithium project in northwest Alberta, Canada, marking a key step toward potential commercial production of battery-grade lithium chemicals.
The company said it collected approximately 150m³ of brine from its 10-6 well between March 21 and April 8, 2026. The material will be used for long-cycle testing of Direct Lithium Extraction (DLE), process optimisation, and conversion into battery-grade lithium carbonate.
In addition to process validation, the sampling campaign is intended to support hydrogeological modelling of the Leduc formation reservoir, which underpins the Boardwalk project. Samples taken during the campaign have been sent to multiple laboratories for assay analysis, with quality control overseen by an independent qualified person in line with NI 43-101 standards.
LithiumBank said the work fulfils a key milestone tied to funding support from Emissions Reduction Alberta, which is backing the project. Completion of this stage enables partial reimbursement of project costs and advances the company toward further milestones, including extended DLE testing and a full feasibility study.
The company is also preparing for additional drilling at a second well (1-12), targeting the Leduc formation. A downhole pressure monitoring system has already been installed in the 10-6 well to improve reservoir modelling and inform future flow testing.
Under the Boardwalk
Boardwalk and the nearby Park Place asset together represent what the company describes as the largest known lithium brine resource in North America, with both projects reporting high-grade resource estimates under NI 43-101. LithiumBank holds more than 1.2 million acres of brine-hosted mineral licences across Alberta and Saskatchewan.
The company has previously piloted multiple DLE technologies and signed a development agreement with Schlumberger(SLB) covering licensing for an integrated extraction process, as it works toward a modular, lower-capex pathway to commercial lithium production.
Results from the current sampling programme, including lithium concentrations and impurity profiles, are expected once laboratory analysis is complete.
