Kachi

• Phase 1 DFS Addendum completed in August 2025 • Potential Phase 2 – construction of second plant with additional total capacity of 25 ktpa (including additional expansion in subsequent phases) • Completion of FEED marks achievement of critical derisking milestone for grid power • Lilac continues to mark important achievements including unveiling its Gen 5 ion exchange DLE technology, completing construction of commercial scale manufacturing facility and signing a binding offtake agreement • Estimated timeline for EIA final approval is 1H2026 • Continued engagement with YPF Luz on Northern Power Line option • Ongoing effort to explore alternative power solutions

Direct Lithium Extraction (DLE) using ion exchange (Lilac technology), without evaporation ponds and with brine reinjection.

25,000 tpa of LCE.

• Total Resources: 11.1 Mt LCE (Measured and Indicated: 8.2 Mt LCE & Inferred: 2.9 Mt LCE)

Kachi is a top tier project, backed by a significant resource and strong economics positioning it competitively within the growing lithium market.

Total resource is estimated at 10.6 Mt LCE4, a globally significant resource.

25-year mine life supported by maiden Ore Reserve statement.

Phase One targets production of 25 thousand tonnes per annum (ktpa) over the LoM to meet the growing demand and specifications of the battery market.

The DLE step employs a novel ion-exchange media and system developed by Lilac Solutions to extract lithium from the brine and elute the extracted lithium with hydrochloric acid solution. DLE process is tailored to mitigate impact on the local community with minimal disruption to land, freshwater table, and water usage.

The project targets production of consistent battery grade lithium carbonate (>99.5% purity) at site without the need for further refining or processing.
