Lithium Power International Ltd Exceeds Industry Standard Specifications for Battery Grade Lithium Carbonate

Lithium Power International Ltd (ASX:LPI) produced 99.92% purity from the original concentrated brine from its trial evaporation ponds at the Maricunga Lithium project in Chile.

This greatly exceeds the industry standard specification for battery-grade lithium carbonate of 99.5%.

Samples will now be sent to potential lithium buyers for analysis as part of LPI’s financing plans for the construction of the mine at Maricunga.

“We are very pleased with the positive results of our latest testing activities,” said Lithium Power International Managing Director Cristobal Garcia-Huidobro.

“Not only do they confirm the high quality and consistency of our product, but also the sustainability of our process.

“We are confident that these results will be well received by potential buyers participating in the Maricunga project financing process.”

About testing

LPI entrusted the work to an independent certified laboratory, IBZ-Salzchemie GmbH & Co KG in Germany.

The tests were carried out under the supervision of LPI’s technology partner, GEA Messo, with the aim of producing up to 10 kilograms of battery-grade Li2CO3.

The chemical analysis and detailed composition of the impurities were as follows:

These results stem from the latest optimizations introduced to the Maricunga lithium production process in January 2022 in the project’s updated Definitive Feasibility Study (DFS).

A relevant test to measure the loss on ignition (LOI) was also carried out for 30 minutes at 500°C, showing an LOI of 0.2%. Accordingly, the purity after LOI was 99.72%.

About LPI and Maricunga

Lithium Power International is a pure-play lithium company with three distinct project regions to provide diversification. One is in the brine region of South America and three are in the spodumene hard rock regions of Western Australia.

The main objective is to develop Chile’s next high-grade lithium mine on the Maricunga Salar in an area known as the Lithium Triangle. LPI has also expanded its holdings of lithium exploration properties in Western Australia.

The Maricunga project is adjacent to the Chile-Argentina highway northeast of Copiapo and 25 kilometers from the port of Caldera. A 23 kV power line crosses the property and is connected to the Chilean 220 kV power grid.

It is a high quality resource with high brine grades, high flow characteristics and high drainable porosity and permeability.
