Sigma Lithium Corporation, a global lithium producer dedicated to powering electric vehicles (EVs), has reported its results for the second quarter ended in June with production of lithium concentrate totaling 68,368 tonnes.
The company has been at the forefront of environmental and social sustainability in the EV battery materials supply chain, and remains on track to meet its 2025 guidance of 270,000 tonnes from its Grota do Cirilo operation in Brazil.
“We maintained production cadence at 68kt and are comfortably on track to deliver on our annual production target of 270kt while preserving pricing power in a volatile market, while upholding some of the highest health and safety standards in the battery materials supply chain: we celebrated two years without accidents or fatalities,” shared Ana Cabral, Sigma Lithium co-chairperson and CEO.
Sales volumes in 2Q25 were 40,350 tonnes, down from the prior quarter and the same period last year, reflecting a decision to withhold product during periods of price volatility. Production volumes were 38% higher year-over-year.
Cost of sales for the quarter was $23.6 million, or $584 per tonne sold. CIF China cash operating costs averaged $442 per tonne, down from $458 in 1Q25 and below the company’s full-year target of $500 per tonne. All-in sustaining cost averaged $594 per tonne, also below the $660 per tonne target.
Summary of metrics.
Cash and cash equivalents stood at $31.1 million as of June 30, 2025, compared to $45.9 million at year-end 2024. Short-term trade finance was reduced to $45.5 million, with total debt of $166.9 million.
Phase 2 expansion
Sigma Lithium continued preparatory work for its Phase 2 expansion, which would add 250,000 tonnes per year of lithium concentrate capacity, bringing total nameplate output to 520,000 tonnes annually. Key site preparation is complete, and the company is reviewing procurement priorities and contracting timelines. Ramp-up is scheduled for 2026.
