Production Beat and Operational Upgrades
Sigma Lithium reported that it produced 35,000 tonnes of lithium oxide concentrate in the second quarter, exceeding its prior guidance of 33,000 tonnes by 6%. The company attributed the strong performance to a comprehensive upgrade of its mining operations.

AdFollowing the successful operational upgrades, Sigma Lithium stated its team is prepared to support plans for a second Cleantech Industrial Plant, and potentially a third. The company provided updated cost and cash flow projections based on this potential expansion.
Key financial projections include:
- All-in sustaining costs (AISC): Projected at $710 per tonne for Phase 1, decreasing to $620 per tonne with Phase 2, and $610 per tonne with all three phases operational.
- Cash Flow: At a realized lithium price of $1,500 per tonne, the company forecasts cash flow of $130 million from Phase 1, rising to $327 million with Phase 2 and $493 million with all three phases.
These cost estimates, as noted by the company, exclude environmental, social, and financial expenses. Investors will be looking for more detailed results when Sigma Lithium releases its full second quarter 2026 financial and operating report, which is scheduled for August 14, 2026.
