Sigma Lithium Achieves Strong Production and Cost Reductions
Highlights from Sigma Lithium's Second Quarter Performance
Production and Revenue Growth
Sigma Lithium recorded production of 68,368 tonnes of lithium oxide concentrate in Q2 2025, representing a substantial 38% increase year-over-year, slightly surpassing its quarterly target of 67,500 tonnes. This achievement underscores the effectiveness of its operational strategies and market readiness.
The company's revenue for the quarter stood at $21.1 million, although it marked a decrease of 62% compared to Q2 2024. This downturn reflects a strategic decision to withhold product during a period of substantial price fluctuations, aimed at preserving pricing integrity and long-term profitability.
Cost Control and Efficiency
Sigma Lithium has continued to maintain cost efficiencies, with cash operating costs in China averaging $442 per tonne for Q2 2025, representing a 12% decrease from the target of $500 per tonne. The all-in sustaining cash costs also came in below target at $594 per tonne, 10% lower than the forecasted $660. This was accomplished through consistent economies of scale and stable operational practices.
By achieving these efficiencies, Sigma Lithium minimized costs even in a volatile market while maintaining strict safety standards—celebrating two years without accidents in its operations.
Construction and Capacity Expansion Plans
Progress continues on the Phase 2 expansion project at Sigma Lithium, with critical site preparation and procurement activities on track to increase overall production capacity to 520,000 tonnes per year. The aim is to leverage the lessons learned from Phase 1 to enhance sustainability and operational efficiencies in upcoming construction phases.
The anticipated outcome of this expansion is transformative for Sigma Lithium, and once fully operational, it will increase the company’s output, thereby consolidating its status as a significant player in the lithium production sector.
Financial Summary
As of June 30, 2025, Sigma Lithium's cash and cash equivalents stood at $31.1 million, demonstrating a commitment to maintaining liquidity despite operational expenditures. The company has made significant strides in reducing its short-term trade finance by approximately $6 million in Q2, addressing its balance sheet effectively.
The total debt was reported at $166.9 million, with a net interest paid of $0.8 million or approximately $12 per tonne of production, emphasizing the company’s focus on financial prudence while pursuing growth.
