A Brazilian court suspended all environmental permits for Sigma Lithium subsidiary Sigma Mining. This ruling halts operations at the Grota do Cirilo project.
The court issued an emergency injunction following a request from the Kinlombola indigenous community. The group alleges Sigma misrepresented the project's proximity to traditional lands.
Grota do Cirilo represents one of the world’s largest hard rock lithium deposits. The suspension threatens Sigma Lithium’s production timelines and revenue.
Sigma Lithium recently listed on the Australian Securities Exchange (ASX) to fund future growth. The company intended this capital for the expansion of the now-halted project.
