LithiumBank finds largest known lithium brine in North America

The mining company says it has found the highest resource grade in Alberta, Canada.

The miner estimates more than 10Mt of inferred lithium carbonate equivalent (LCE), at a grade of 79.4mg/L lithium within the Leduc Formation.

It also estimates more than 11.6Mt of inferred LCE at 80.9mg/L of lithium within the Swan Hills formation aquifer, underlying its 100%-owned Park Place lithium brine project in west-central Alberta.

The assessments were prepared using 3D static modelling, mining workflows.

The total inferred mineral resource for the Park Place project is over 21.6Mt of LCE between the two formations and a combined average grade of 80.2mg/L of lithium.

The company has spent the past five years cosolidating Park Place brine-hosted mineral licences and has culminated in this 100% ownership.

LithiumBank CEO Rob Shewchuk says, 'We believe this can be expeditiously achieved as we can make use of our knowledge gained from our Boardwalk Preliminary Economic Assessment...located approximately 50km to the north, in which the Leduc Formation brine is similar in chemistry, depth of resource, porosity and permeability.

'Park Place brine will be chemically and metallurgically evaluated at the company's, exclusively licensed, 10,000L/day direct lithium extraction pilot plant in Calgary following a bulk brine sampling programme in H2 2024.'
