We review the company’s operating profile, including all-in sustaining costs near $600 per tonne, historical production levels of 220–270kt per year, and management’s view that the operation remains profitable across a wide range of lithium price scenarios. We also examine several key developments: • Transition from contract mining to owner-operated mining and the potential impact on safety, productivity, and margins• Plant performance and recoveries (~70% DMS)• Monetization of high-purity fines inventory as an incremental revenue stream• Status of Phase 2 expansion, with most civil works completed and remaining equipment capex outlined• Funding strategy, including cash flow, development bank financing, and customer prepayments/offtakes• The depth of Sigma’s technical and operational team as it scales production Our goal in this discussion is to clarify what has changed operationally, what risks remain, and how management is approaching capital discipline and growth in the current lithium market.
