SIGMA LITHIUMCEO ANA CABRAL NAMED “MINING PERSON OF THE YEAR” DURING LONDON METAL EXCHANGE WEEK 2023

SAO PAULO, BRAZIL – (October 12, 2023) – Sigma Lithium Corporation (“Sigma Lithium” or the “Company”) (NASDAQ:SGML, BVMF: S2GM34, TSXV: SGML), a leading global lithium producer dedicated to powering the next generation of electric vehicles with carbon neutral, socially and environmentally sustainable chemical-grade lithium concentrate, is honored to announce that CEO and co-founder Ana Cabral has been named “Mining Person of the Year” for 2022 by The Northern Miner.

Ana received the prestigious award for “Mining Person of the Year” at the Canadian Mining Symposium 2023 during London Metal Exchange Week in London, U.K., where she also shared her thoughts on the role critical minerals will play in shaping the Green Energy Transition.

The “Mining Person of the Year” award is selected each year by the Northern Miner Group for outstanding and timely contributions to the field of mining. This acclaimed award signifies Cabral’s outstanding leadership and impact on both Sigma Lithium and the broader mining industry.

Over six years of her leadership, she has shaped the culture of Sigma Lithium as an inclusive meritocracy, where talented individuals of all genders, ages and races are rewarded for their performance and commitment to execute according to the ESG-centric purpose of the company.

Ana has been a leading executive director of Sigma Lithium since its inception as a small junior explorer in 2012. She joined the management team full time in 2016 as a co-leader, turning the company around from bankruptcy into one of the world’s largest lithium producers, delivering the pioneering “Triple Zero Lithium”: Zero Carbon, Zero Tailings, Zero Hazardous Chemicals, reusing 100% of the water.

Commenting on the award, CEO Ana Cabral said, “I am honored to have been selected by Canada’s The Northern Miner as ‘Person of theYear’ (a woman from Latin America). We are just getting started as a producer but have already reached the consistency and cadenceof shipments that are the hallmarks of established producers in scale.”

“We haveworked incredibly hard to earn this recognition, often against market cycles, deploying proprietary capital for many years to make SigmaLithium a reality and execute on our vision.”

“Thisaward is the result of the collective effort of a resilient, resourceful, and relentless team which has worked hard over more than adecade to transform our vision into reality. In our industry where ideas abound, success in execution is determined by commitment tostrategy and brutal hard work. And more importantly, we firmly believe that success is always a result of a 360-degree view of how theCompany is integrated for minimal impact on the natural ecosystems around it; and how it integrates for maximum positive impact on neighboringcommunities.”

“I amvery proud of the deep bench of talent at Sigma, incredibly dedicated to deliver impeccably on our shared mission. We started small andregionally: our hope was to transform our Vale do Jequitinhonha into a much better place than it was when we started to invest therein 2012.”

“As wegrew our business into a ‘Global Force for Good’ in the lithium sector, we were able to demonstrate to the wider industrythat our success was certainly due to our sustainability ethos. Hence it is very rewarding to witness the change we have been helpingcatalyze in the way our metals & mining industry takes to a higher level its positive contributions to society and communities.”

Alisha Hiyate, Editor-in-Chief of The Northern Miner, commented, “We believe Ana's leadership was essential in Sigma Lithium's rise from IPOin 2018 through construction and commissioning of the Grota do Cirilo mine, and first production in 2023. As a co-founder, then co-CEOand most recently as CEO, she has been key to the company's ability to obtain financing in each stage, and the company's impressive shareprice rise since early 2022. Under Ana's leadership, the company committed to developing Grota do Cirilo with the lowest possible environmentalimpact, targeting end-user and consumer concerns. And she has been a driving force behind Sigma's first-mover status, opening up Brazilas a significant new lithium mining jurisdiction. This is why we named her our ‘Mining Person of the Year’ for 2022.”
