An emergency supply disruption hit the lithium battery industry chain over the weekend: A court in Minas Gerais, Brazil, issued an emergency injunction freezing all environmental approval permits for Sigma Lithium's Grota do Cirilo mine, forcing a full shutdown of the mining operation, and the mineral processing plant simultaneously lost its raw material supply. The company has the right to appeal, but must complete the traditional community consultation process, **the resumption time is highly uncertain**, and it cannot quickly resume production by paying fines for rectification.

Core Production Capacity Data

• Nominal capacity of the first-phase lithium concentrate: 270,000 tons/year, 2026 production guidance is 240,000 tons of lithium concentrate, equivalent to approximately 34,000-38,000 tons LCE
• Global share: Accounts for approximately 3% of global lithium concentrate trade volume, just over 1% of global total lithium supply; accounts for approximately 60% of Brazil's lithium output, most of which flows to the Chinese market
• Incremental expansion plan: Originally planned to expand the second phase to 520,000 tons of lithium concentrate, as an important global lithium supply increment in 2027, the current expansion process is blocked by Sigma Lith...

Core Reasons for the Shutdown

This judicial lawsuit was initiated by the local indigenous Kiriri community, not an ordinary environmental protection penalty. The plaintiff accused the company of falsifying the distance between the mining area and the traditional territory in the environmental assessment materials. The measured distance of 2.7km falls within the 8km mandatory community consultation impact scope stipulated by Brazilian law, and the mining has damaged local water sources and ecology. The court froze all environmental permits based on this. The mine has received multiple environmental and labor penalties in 2026, and was temporarily shut down for rectification in July, with long-standing compliance risks in the project.

Objective Market Judgment: Emotional Catalyst, Hard to Reverse the Overall Supply and Demand Pattern

1. Spot supply gap can be hedged: Existing lithium mines in Australia and Africa have idle capacity to increase production, and the physical supply gap can be replaced. Domestic smelters have diversified raw material sources, and no single manufacturer is highly tied to this mine, so the actual supply impact is limited.
2. The market trend is an event-driven pulse: The event amplifies the vulnerability of overseas hard-rock lithium mine supply, raising expectations for a rebound in lithium concentrate and lithium carbonate prices; the market is highly anchored to the appeal outcome. If a settlement and resumption of production are reached quickly, the disturbance will subside rapidly; if the shutdown lasts for a long time, the impact will mainly be reflected in the **contraction of 2027 supply increments**, rather than the current spot fundamentals.
3. Industrial chain differentiation: Assets with high self-sufficiency in lithium resources will benefit relatively; smelting enterprises that highly rely on imported Brazilian lithium concentrate face pressure on rising raw material costs. The community and ESG compliance risks of South American lithium mines have been repriced, and the logic of domestic lithium resources being independently controllable has been strengthened.

Key Follow-up Points

① Submission of the company's appeal, court hearing and ruling result; ② Progress of negotiations on traditional community consultation; ③ Changes in spot lithium concentrate prices; ④ Whether the second-phase expansion plan will be adjusted.
