Sigma Lithium Corporation continues to add experienced top talent to senior leadership roles as it becomes one of the world’s largest lithium producers.

Matthew DeYoe will join as the Company’s Executive Vice President for Corporate Affairs and Strategic Development, based in the United States. This appointment, effective immediately, seeks to enhance Sigma Lithium’s direct personal interface with global investors, maximizing the value of Sigma Lithium’s common shares listing on the Nasdaq Stock Exchange, where the Company’s public float currently trades.

DeYoe is joining the company from Bank of America, where he was the leading coverage research director for lithium and chemical companies over the past four years.

Growth strategy and new market opportunities

Mr. DeYoe will also advise the management team on its growth strategy and new market opportunities. Before Bank of America, he held positions on the buy-side at hedge funds where he specialized in chemical, lithium, and energy investments. DeYoe holds a Bachelor of Science degree in Business Administration from Georgetown University and is a CFA charter holder.

Sigma Lithium is also augmenting its world-class environmental team by hiring Alexandre Mattos as Environmental Director. Mr. Mattos has 18 years of experience running every operational environmental aspect of a large producer in metals and mining. He joins Sigma Lithium from Kinross Mineração Brazil, which has over 1,700 people at its operating site in Brazil. He served there for over 10 years and oversaw a team of 53 full-time employees and an additional 30 contractors.

Mattos’ role extended across Kinross’ largest mining operations as well as its hydroelectric plants. His oversight encompassed various critical areas, including environmental controls, biodiversity preservation, water resources, integrated management systems, and licensing. His responsibilities also included work safety, occupational hygiene, emergency preparedness and management, and critical risk mitigation. Mattos is an environmental engineer and holds a master’s degree in Land Planning and Environmental Management from Universitat de Barcelona, Spain. He also holds a postgraduate degree in Occupational Safety from PUC in Brazil as well as an MBA in Environmental Studies from Fundação Getulio Vargas in Brazil.

He will be based at Sigma Lithium headquarters at Vale do Jequitinhonha, where he will work alongside Sigma’s general managers and senior operating team.

Investor relations

Matthew DeYoe commented, “Sigma Lithium appealed to me as a company that is executing at a high level. The team at Sigma has delivered on its commitments time and again. With a low-cost position and significant opportunity for growth, it is easy to see Sigma becoming a market leader in the lithium supply chain. The company is also doing it the right way. Sigma’s commitment to sustainability and carbon neutrality makes it a force for good in a world which often sacrifices these issues.

“I look forward to contributing my experience to Sigma Lithium’s Canadian and Brazilian investor relations teams to unlock significant shareholder value as the company has transitioned to a producer and cash flow generator,” he continued.

Commenting on the appointment, Co-chairperson and CEO Ana Cabral said, “Sigma Lithium has delivered on every operational and sustainability milestone on time. Matt’s willingness to lend his expertise and experience is a testament to his belief in our execution expertise and vision to join the select group of global lithium super majors: large-scale and low-cost producers. We are now shipping over 20,000 tonnes a month, reaching over 90% of ramp-up capacity, and annualizing 270,000 tonnes a year. Several of our exceptionally driven teams will be further bolstered by the appointment of Matthew DeYoe, with his depth of knowledge and experience in the lithium industry. He has hit the ground running, visiting our Greentech Plant and production site and teams in Brazil this week, and will join me in Sydney, Australia at our investor event during the International Mining and Resources Conference (IMARC).”
