Boardwalk Lithium Brine Project mineral title map highlighting the ‘Production Zone’<\/figcaption><\/figure>\nThe brine used in the DLE test work was collected in August 2021 from Well 100\/09-26-068-22WS\/OO located in the South Sturgeon Lake oilfield (see figure 1) within the ‘Production Zone’ and has a reported average grade of 73.8 mg\/L Lithium (as previously reported in LithiumBank news release dated June 28, 2022).<\/p>\n
LithiumBank first engaged Hatch in August 2021 to conduct a comparative study of a number of North American-based DLE technologies that could deliver a high purity Lithium Chloride (LiCI) concentrate on being used in commercial, battery-grade lithium chemical production from the Boardwalk brine. After an iterative process by Hatch, LithiumBank has narrowed the potential technology providers, with Conductive technology providing the most optimal results.<\/p>\n

The Boardwalk Leduc Formation Li-brine inferred resource, as of May 18, 2021, is globally estimated at 1,122,000 tonnes of elemental Li at an average lithium concentration of 67.1 mg\/L Li in 16.7 km3<\/sup> of formation brine volume (Table 2). The global (total) lithium carbonate equivalent (LCE) for the inferred mineral resource is 5,973,000 tonnes of LCE at an average grade of 67.1 mg\/L Li (as reported May 31, 2022).<\/p>\nMineral 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. While bench-scale and demonstration pilot plants operated by companies other than LithiumBank are reportedly having success in the recovery of high-purity battery-grade lithium from subsurface confined aquifers, DLE technology is in the development stage and has not yet been proven at a commercial scale.<\/p>\n","protected":false},"excerpt":{"rendered":"
