SÃO PAULO, Dec. 27, 2023 -- Sigma Lithium Corporation ("Sigma Lithium" or the "Company") , a leading lithium producer dedicated to powering the next generation of electric vehicles with carbon neutral, Quintuple Zero Green Lithium concentrate, is proud to cap off an incredible year for the Company by loading one last shipment of 22,000 tonnes of concentrate to Glencore at the Port of Vitoria. Sigma Lithium's fifth shipment is expected to leave port by year-end.

Glencore will prepay 50% of the fifth shipment's value upon completion of loading. The 50% prepayment reflects a provisional premium price for the Company's unique Quintuple Zero Green Lithium concentrate.

Sigma Lithium has completed an incredible journey over the past twelve months, having gone from commissioning the crushing unit in December of 2022 on schedule and on budget, to sustaining nameplate production levels at its Greentech lithium concentrate plant in December 2023. Operating rates at these levels would support a monthly shipment cadence of roughly 22,000 tonnes through the course of 2024, annualizing approximately 270,000 tonnes of Quintuple Zero Green Lithium concentrate.

Sigma Lithium CEO, Ana Cabral-Gardner commented, "We have a relentless, resilient team who has been working for years on a mission that has become our collective legacy: supporting the electric vehicle revolution by delivering the most sustainable lithium material in the world. In the process we became a better version of ourselves, transforming the lives of the people around us by providing economic empowerment, inclusion, citizenship. We are laying the foundation for common prosperity where metals, mining and metallurgical industries are fully embraced by communities as the drivers of technological and environmental innovation as well as positive social change. Our team has rarely set a foot wrong, nor missed our operational deadlines. We delivered on our promises, including those that seemed impossible at the time, such as achieving Carbon Neutrality / Net Zero 27 years ahead of the metal and mining industry."

Ligia Seca, Director of Institutional Relations: "We carry an enormous sense of mission and purpose on our shoulders: There are over 13,000 people in our communities who are benefitting from Sigma Lithium's investments and growth. We continue to invest heavily in technology to be able to beneficiate our lithium concentrate in harmony with nature: Producing what has now become the most sustainable lithium in the world, honoring all the high expectations placed upon us by our country and our people. As a result, we have opened a whole new set of opportunities for Brazil to become a key participant in the most coveted global sustainable supply chains for battery materials."

Matthew DeYoe, EVP of Corporate Affairs & Strategic Development: "Sustaining production at nameplate capacity was the final step in gaining confidence that Sigma's operations have completed the ramp process. Our team overcame incredible challenges to deliver something that has never been done before, a dry-stack tailing process with zero net carbon and 100% water reuse in the production circuit. I am incredibly proud of the work the site-team has done over the past year and I look forward to keeping the momentum going into 2024." 

Sigma Lithium is a leading global lithium producer dedicated to powering the next generation of electric vehicle batteries with carbon neutral, socially and environmentally sustainable chemical-grade lithium concentrate.

Sigma Lithium has been at the forefront of environmental and social sustainability in the EV battery materials supply chain for six years and it is currently producing Quintuple Zero Green Lithium from its Grota do Cirilo Project in Brazil. Phase 1 of the project is expected to produce 270,000 tonnes of Quintuple Zero Green Lithium annually (36,700 LCE annually). If it determines to proceed after completion of the detailed engineering study, Phase 2 & 3 of the project are expected to increase production to 766,000 tonnes annually (or 104,200 LCE annually). The project produces Quintuple Zero Green Lithium in its state-of-the-art Greentech lithium plant that uses 100% renewable energy, 100% recycled water and 100% dry-stacked tailings.
