Operated by Sigma Mineração S.A, Grota do Cirilo is a lithium mineral project located in Minas Gerais, Brazil. In 2014, Sigma acquired the lithium rights across a large and previously productive area of the Eastern Brazilian Pegmatite Province. Several historic mines and pegmatites exist across the tenements. Construction of a staged open pit mining and processing operation commenced in late 2021. Output is expected to reach 440ktpy of 6% spodumene concentrate in 2025.
