Calgary, Alberta. December 11, 2023 – LithiumBank Resources Corp. (TSX-V: LBNK) (OTCQX: LBNKF) (“LithiumBank” or the “Company”) is pleased to announce that the G2L Greenview Resources Inc. (“G2L”) Direct Lithium Extraction (DLE) pilot plant is now in transit to LithiumBank’s Calgary facility. Once completed, the facility will have capacity to process up to 10,000 L/d of brine and yield up to 3 kg/d LCE. Commencing in early 2024, several piloting campaigns are planned as the Boardwalk Project advances into its feasibility studies phase of development. The Company also anticipates that the facility will accelerate the development of the Company’s Park Place, Estevan, South, and Kindersley properties.
The pilot plant has been constructed in Australia by Clean TeQ Water on the behalf of G2L and is based on G2L’s Continuous Direct Lithium Extraction (cDLE®) technology. As seen in recent testwork results (Reported Nov. 22, 2023), the cDLE® process utilizes an ion exchange material (sorbent) designed to selectively extract lithium from the brine while rejecting most contaminants. In the context of the Boardwalk Project, the configuration of the pilot adsorption and elution stages has been purposefully designed to maximize extraction of lithium from the brine. Similarly, the selectivity of the sorbent and elution chemistry allows strong rejection of typical impurities in the brine such as sodium, calcium and chloride. This results in a clean, lithium-rich concentrate suitable for further refining.
At the facility in Calgary, the cDLE® process will demonstrate the cost and process advantages of using common industrial reagents such as quicklime and sulfuric acid. The operating cost benefits of this change in reagent suite will be quantified in an updated Boardwalk Project Preliminary Economic Assessment. Senior process engineers from G2L will head up the installation of the pilot and the first 100 hours of processing. G2L will continue to lend support throughout the entire piloting program which is intended to last up to 18 months following the first 100 hours of operation.
With a processing capacity of up to 10,000 L/d of brine, the Calgary facility will represent one of the largest DLE pilot plants in North America. The pilot plant represents an approximate 1:5,000 scale to the future, commercial production modules which is consistent with scale-up factors used in other hydrometallurgical processes. Within the pilot plant, sufficiently large ion exchange equipment has been installed to permit direct scale-up of these process steps to the commercial plant, accelerating the Boardwalk Project development.
During operation, the pilot plant will be targeting one of the industry’s highest lithium recoveries. This is seen as achievable for the Boardwalk project given the project’s careful staging of adsorption and elution contactors, along with the characteristics of the sorbent. Specifically, experiences from industrial ion exchange processes used for the recovery of precious (gold) and energy (uranium) metals have been leveraged in formulating the Boardwalk DLE flowsheet. This formulation included a trade-off assessment of lithium recovery and capital cost which was undertaken for the purposes of the upcoming updated PEA. As a result, the pilot plant will assess the performance of five contactor stages with results to follow in the PEA.
Furthermore, G2L’s experience in pilot testing of continuous ion exchange for recovery of other metals, including nickel and cobalt, at a similar scale in similar pilot equipment, provides confidence that recovery using counter-current adsorption contactors can be predicted from laboratory scale test work.
The cDLE® pilot plant in transit is a variation of a pilot plant that was designed and constructed by the Clean TeQ Water technical team to extract nickel and cobalt by ion exchange from acid leached lateritic ore in the Sunrise Energy Metals project. The plant was run over several campaigns and the data were subsequently used for a Bankable Feasibility Study (BFS) on the production of battery-grade nickel and cobalt sulfates. The Boardwalk Project cDLE® plant uses the same basic configuration, with critical design changes incorporated to ensure maximum lithium extraction from the brine, and the production of a high purity eluate containing a high lithium concentration.

Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no guarantee that all or any part of the mineral resource will be converted into a mineral reserve. The estimate of mineral resources may be materially affected by geology, environment, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues. A preliminary economic assessment is preliminary in nature as it includes a portion of inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized.
