Phase 2 Development Progress
During the three months ended December 31, 2025, Sigma Lithium’s focus remained on mine development, aiming to allow the existing pit to feed both Phase 1 and Phase 2 Greentech Processing Plants for a period of 6 months starting from the beginning of the ramp-up of Phase 2 operations.
The Phase 2 expansion remains a transformative opportunity for the Company, with expected additional production capacity of 250,000 tonnes per annum of 5% lithium oxide concentrate. Together with Phase 1, this would bring the total annual production capacity at Grota do Cirilo to 520,000 tonnes of 5% lithium oxide concentrate.
The Company continues to leverage the synergies and learnings from Phase 1 to enhance the efficiency and sustainability of Phase 2 implementation. The aim is for long lead items to be ordered in the second quarter of 2026 and construction to commence in the second half of 2026.
