The company’s flagship asset is the Grota do Cirilo hard‐rock lithium deposit in the state of Minas Gerais, which is one of the world’s highest‐grade, large‐scale spodumene deposits. Sigma Lithium aims to produce battery‐grade lithium concentrate to supply the growing demand for electric vehicles and energy storage systems. Through its vertically integrated operations, Sigma Lithium oversees all stages of the lithium production process, including exploration, mine development, processing, and logistics. The Grota do Cirilo site features a fully permitted processing plant that employs gravity and flotation circuits to concentrate spodumene ore. Once processed, the lithium concentrate is shipped to battery and chemical producers across North America, Europe and Asia for further refinement into lithium carbonate or lithium hydroxide. Environmental stewardship and social responsibility are central to Sigma Lithium’s operating philosophy. The company has implemented water recycling programs, tailings management systems and renewable energy initiatives to minimize its carbon footprint. It also engages with local communities around its Brazilian operations to support infrastructure improvements, education and job creation. Sigma Lithium regularly publishes sustainability reports outlining its progress against key environmental, social and governance (ESG) metrics. Founded by a team of mining and finance professionals, Sigma Lithium began consolidating the Grota do Cirilo property in 2018 and advanced to commercial production in 2022. The company is led by CEO Paulo Castellari, who has over two decades of experience in mineral project development.
