Sigma Lithium Corporation reports developments tied to its lithium oxide concentrate production business and its Grota do Cirilo operation in Brazil. Company news commonly covers earnings releases, production guidance, sales of high-grade lithium oxide concentrate, commercialization of high-purity lithium fines, offtake agreements, and working-capital or bank-guarantee arrangements.
Updates also describe the Greentech Industrial Plant, including dry stacking, water reuse, zero use of toxic chemicals, and renewable electricity, along with capacity-expansion activity. Recurring themes include operating cadence, mine optimization, customer deliveries, and the role of Sigma Lithium's concentrate in the electric battery materials supply chain.
Sigma Lithium (SGML) temporarily suspended all mining and industrial production on September 30, while maintaining its fiscal 2027 production guidance. The company continues to expect 330,000 tonnes of lithium oxide concentrate in fiscal 2027, but will postpone its 12-month guidance of 240,000 tonnes by three months.
Commercial and recycling operations will continue, including sales of high-purity lithium fines and recycling of 100% of dry-stacked tailings. These activities generate cash flow, and Sigma Lithium expects to continue self-funding during the suspension. The company remains focused on expansion and plans to resume its Phase 2 expansion in 2027, designed to increase annual production capacity to 580,000 tonnes. A planned Phase 3 expansion would increase annual capacity further to 830,000 tonnes.
