Project Improvements - The DFS Addendum design basis was set at 249 mg/L of lithium concentration, enabling more efficient lithium extraction[11] - Lithium recovery rates increased from approximately 80% to 90% with the transition to Lilac Gen4 Ion Exchange (IX) technology[11] - The number of wells was reduced by approximately 22%, representing a 35% and 44% improvement in well Capex and Opex, respectively[11] Capital Expenditure (CAPEX) - CAPEX was reduced to US$1,157 million, representing an approximate US$220 million improvement from the Original DFS figures[10, 12] - This represents a 19% improvement from the inflation-adjusted baseline or a 16% improvement from the Original DFS[12] - A reduction of approximately US$98 million in savings was achieved due to the reduction in DLE modules, which reduced major equipment, civil works, and installation costs[23] Operating Expenditure (OPEX) and Financials - OPEX meaningfully improved to US$5,895/t LCE, representing a 3% improvement from Original DFS numbers[10, 12] - The estimated pre-tax NPV10 is US$1.5 billion, and the pre-tax IRR is 22.5%[10] - The plant design basis was updated to 249 mg/L to reflect improved lithium concentration[12] Resource and Risk Reduction - The measured resource increased from 3.0 Mt LCE to 4.2 Mt LCE, and the total resource increased from 10.6 Mt LCE to 11.1 Mt LCE[12] - The wellfield development plan represents less than 9% of the Measured & Indicated Mineral Resource[76] - The company expects Exploitation EIA final approval in 2025[12]
