Sigma Lithium starts processing plant commissioning, reports leadership changes

Sigma Lithium announced initiation of commissioning of its dense medium separation processing plant, one month ahead of schedule. It also announces certain leadership changes. Brian Talbot will continue to lead operations as COO of Sigma Lithium. Talbot has been working with the company since 2021, leading the operating team on site playing a role in the execution of project commissioning. He also serves on the company’s Technical Committee. Ana Cabral-Gardner, previously co-CEO, continues as CEO of Sigma Lithium. She will also continue as co-chair of the company’s board of directors. As part of the transition, Gary Litwack, currently Sigma Lithium’s lead independent board director, has been appointed non-executive co-chair of the board. Further, in preparation for evolving financial reporting responsibilities as the company transitions from developer to producer, Rodrigo Menck, who joined the company in 2022, has been named CFO of Sigma Lithium. Felipe Peres, former CFO, will continue to work closely with the finance team in the capacity of senior advisor to the company. Menck has roughly 30 years of experience in finance and capital markets. He has spent the last 15 years leading finance functions for large corporations, including most recently with Nexa Resources. Calvyn Gardner, who had been co-CEO and co-chair of the board, will remain on the board.
