The PEA was completed by Ausenco Chile Limitada (“Ausenco”) in accordance with National Instrument 43-101 Standards of disclosure for Mineral Projects (NI 43-101). The assessment includes and demonstrates that the Arizaro project has the potential of a 25,000 tonnes per annum (“tpa”) commercial-scale operation to produce battery-grade lithium carbonate (“LCE” or “Li2CO3”).
Under the leadership of President and CEO,
Lithium Chile’s President,

SENSITIVITY
Sensitivity analysis that was conducted on the Arizaro project revealed that the project is most sensitive to changes in lithium carbonate price, and to a lesser extent to initial capital costs, operating costs and sustaining capital requirements.

Cautionary Statement: The reader is advised that the PEA summarized in this news release is intended to provide only an initial, high-level review of the Project potential and design options. The PEA mine plan and economic model include numerous assumptions and the use of both indicated and inferred mineral resources. Inferred mineral resources are too speculative to be used in an economic analysis except as allowed for by NI 43-101 in PEA studies. Mineral resources are not mineral reserves and do not have demonstrated economic viability.There is no certainty that the Arizaro project envisioned by the PEA will be realized.
UNIQUE PROJECT ADVANTAGES
The process selection considers the incorporation of a Direct Lithium Extraction (DLE) stage. DLE processes have shorter start-up and ramp-up times, mainly due to their smaller infrastructure requirements and the ability to be designed with a modular concept. This modularity allows for incremental expansion, enabling a faster ramp-up to meet increasing demand. Additionally, the crucial aspect of brine's chemical composition homogeneity further enhances the efficiency and effectiveness of the process. With consistent brine composition, DLE operations achieve more predictable and reliable lithium recovery rates, enabling better production capacity planning and meeting demand requirements with confidence. Overall, integrating DLE into the process proves to be a strategic choice, streamlining operations and ensuring a reliable supply of lithium.
Multiple opportunities to enhance project economics through optimization and further engineering have already been identified.
More than 60 technologies combination were studied during PEA and trade off permits to optimize main sustainability variables, water and energy usage, water basin balance, reagent usage and Capex and Opex.
Major discovery of lithium brines in the basin and major metallurgical testing including best possibilities for water and energy usage.
Unique Technical team with operation, projects and production experience.
Initial production water aquifer identified and permitting underway.
