Sigma Lithium (NASDAQ:SGML) Corp. is a Canada-based mineral exploration and development company focused on the sustainable production of battery-grade lithium from hard rock deposits. The company’s flagship asset is the Grota do Cirilo lithium project, located in the state of Minas Gerais, Brazil. Grota do Cirilo comprises a fully permitted, low-altitude spodumene mine and processing plant designed to produce high-purity lithium concentrate and downstream lithium hydroxide for the global electric vehicle and energy storage markets.
Since its founding in 2018, Sigma Lithium has pursued a vertically integrated approach, overseeing each stage of production from ore extraction and beneficiation to chemical conversion. The company emphasizes environmental stewardship and aims to minimize its carbon footprint through measures such as water recirculation, tailings dry stacking, and renewable energy use. In 2023, Sigma Lithium commenced commercial concentrate shipments, marking a key milestone in its strategy to become a reliable supplier of critical battery materials.
Headquartered in Vancouver, British Columbia, Sigma Lithium operates primarily in Brazil but serves customers and investors worldwide, including North America, Europe and Asia. Its leadership team is led by President and Chief Executive Officer Stefan Acker, who co-founded the company with Eduardo Ribeiro and brings extensive experience in mining development and project financing. Under their guidance, Sigma Lithium has raised capital through equity and strategic partnerships to advance its growth pipeline and future expansion initiatives.
As demand for electric vehicles and renewable energy storage continues to climb, Sigma Lithium positions itself as one of the first hard rock lithium producers in Latin America with commercial output. The company remains focused on optimizing plant performance, expanding production capacity and delivering battery-grade lithium products that meet the evolving quality and sustainability requirements of manufacturers worldwide.
