Grota do Cirilo is a “Tier-1” project that is among the largest and highest-grade hard rock lithium deposits in the world, with excellent metallurgy and low impurities. Sigma Lithium is expected to be a top 5 lithium producer globally upon achieving full-scale commercial production at its Grota do Cirilo Project.
Grota do Cirilo is expected to deliver a unique coarse and high-quality lithium concentrate, which will deliver higher margins and operational efficiencies for Sigma Lithium’s end users. The coarse size of the concentrate has the potential to deliver 20 to 30 percent greater efficiency in the lithium hydroxide and carbonate chemicals production process.
Sigma Lithium is currently focused on constructing the Grota do Cirilo Project in a phased approach, with Phase 1 production to commence from the Xuxa deposit in 2023 (commissioning expected by year-end 2022). Production is expected to be approximately doubled by 2024 via a Phase 2 expansion through the development of the nearby Barriero deposit.
Sigma Lithium has conducted significant metallurgical testing at its Grota do Cirilo Project, conducting pilot plant production at site since 2018. Grota do Cirilo’s excellent metallurgy has been further validated by Sigma Lithium securing world-class offtake partners including LG Energy.
Sigma has tremendous exploration potential including over 200 identified pegmatites on its ~20,000 hectare land package (200 km2), representing 27 mineral rights.
