The Preliminary Assessment confirms an inferred lithium resource of 1.15 million tonnes of lithium carbonate equivalent ("LCE") at a weighted average grade greater than 143 mg/l within Hub City Lithium's Mansur and Viewfield project areas. The Preliminary Assessment evaluates more than 300 wells within the region and evaluates 8 stacked zones of high lithium concentrations within the Duperow formation.
Importantly, the Preliminary Assessment also identifies an inferred resource of greater than 500,000 tonnes with concentrations above 198 mg/l with a cutoff grade of 140 mg/l applied. Hub City Lithium remains focused on areas of highest economic potential which combine high reservoir capacity and high lithium concentrations to create a value density that is expected to optimize development economics. Clearly, the Hub City Lithium projects are showing excellent value density, which combined with the relatively shallow 1,800m drill depths and no contamination from H2S or oil residue, is expected to improve project economics over the initial stages of development and during critical payout periods.
"The reservoir quality and high lithium concentrations of up to 259 mg/l have created an unusually high value density within our project areas. We certainly believe that this value density will lead to significant development advantages. We are excited to now be working with Sproule to develop a Preliminary Economic Assessment and outline the capital and lifting cost advantages of this project," commented

A follow up vertical well at Viewfield will be drilled and tested no later than Q3 2023 to provide additional test data and to provide a water disposal well for future flow testing of horizontal wells.
The initial phase of the PEA will only be evaluating a portion of Hub City Lithium's land, specifically 4,100 hectares (10,000 acres) which represents approximately 5% of its land holdings. Step by step expansion of the PEA into the offsetting land blocks will allow Hub City Lithium to expand its development program and the ultimate recoverable resource.
Selection of a direct lithium extraction ("DLE") technology provider is underway with large samples currently being sent for testing by multiple prospective DLE technology providers.
