LPI Produces Battery Grade Lithium Carbonate With 99.92% Purity From Maricunga Project

HIGHLIGHTS

• Optimisations introduced to the production process of LPI’s Maricunga lithium project exceed industry standards, with 99.92% purity battery grade lithium carbonate being produced from samples of concentrated brine.
• Technical certification by IBZ Salzchemic GnbH & Co, under international standards, was conducted under the supervision of GEA Messo in Germany and LPI’s experts in Chile.
• Samples will now be sent to potential lithium buyers for analysis as part of LPI’s financing plans for mine construction at Maricunga.

A relevant test to measure the Loss of Ignition (“LOI”) was also conducted for 30 minutes at 500 °C,

showing an LOI of 0.2%. As a result, the purity after LOI was 99.72%.

As announced in the March 2022 Quarterly Report released to ASX on 29 April 2022, concentrated brine had been sent to LPI’s technological partner GEA Messo to further test production processes.

This work was executed by the independent certified laboratory, IBZ-Salzchemie GmbH & Co KG in Germany. This was done under the supervision of GEA, with the objective of producing up to 10kg of battery grade Li2CO3.

Lithium Power International’s Chief Executive Officer, Cristobal Garcia-Huidobro, commented:

“We are very pleased with these positive results from our latest testing activities. Not only do they confirm the high quality and consistency of our product, but also the sustainability of our process. We are confident that those results will be welcomed by potential off-takers participating in the financing process of the Maricunga project.”
