Sigma Lithium signs deal to supply sustainable lithium to Glencore

Sigma Lithium (“Sigma Lithium” or the “Company”) a global lithium producer dedicated to powering the next generation of electric vehicles with carbon neutral, socially and environmentally sustainable chemical-grade lithium concentrate, announced that it has successfully prepared 22,500 tonnes of battery-grade, carbon neutral, zero hazardous chemicals and zero tailings sustainable lithium (“Triple Zero Green Lithium”) at Vitoria Port to be shipped to Glencore.
The shipment is part of an agreement with Glencore that aims to build a low carbon, environmentally and socially
sustainable global lithium supply chain for electric vehicles.
“We are delighted to partner with Sigma Lithium, as we continue to offer our customers responsibly produced,
low carbon lithium,” said Robin Francois, Lithium Trader at Glencore. “This partnership also underpins our
ambition to become a partner of choice for the provision of such a critical mineral to the battery and EV industry,
thereby supporting the energy transition.”
“Sigma Lithium and Glencore are building an EV supply chain that is focused on providing lithium materials that are
responsibly sourced in an environmentally and socially sustainable manner,” said Ana Cabral, Sigma Lithium CEO
& co-Chairperson. “Given the critical role of EVs in reducing the carbon footprint of the transportation sector,
Glencore and Sigma Lithium’s joint efforts are fully aligned with our clients’ approach to responsible sourcing and
supply chains built in line with the ethos of the consumer of the EV.”

“At Sigma Lithium, we believe that businesses have a critical role to play in combating climate change, particularly
in the mass transition to electric vehicles. Our Triple Zero Green Lithium set a high standard of sustainability to
fully support the electric vehicle industry in reducing its environmental footprint. By successfully achieving net
zero carbon production, we have proven that our industry can effectively embrace sustainable practices and
pave the way towards a greener future,” she added.
Sigma Lithium’s Triple Zero Green Lithium: The foundation of a globally sustainable supply chain
Sigma Lithium effectively lowered its carbon footprint with a series of pioneering initiatives, paving the way
forward for the metals & mining sector.
The Company’s Triple Zero Green Lithium is produced at its state-of-the-art Greentech lithium plant at its Grota
do Cirilo Project in Brazil, the first lithium project in the world without a tailings dam. With 100% dry-stacked
tailings and the absence of hazardous chemical products for processing lithium, the Company is preventing
water and soil contamination and contributing to the preservation of rivers and forests in the region.
The Company’s main achievements towards abating its carbon footprint include:
• Zero tailings: 100% dry stacked tailings, with all by-products eliminated through sales or upcycling to pave
roads.
• Zero hazardous chemicals: Utilizes Dense Medium Separation (“DMS”) at the Greentech plant, which
does not utilize hazardous chemicals.
• Water efficiency: Utilizes 100% sewage water for its plant, fully recirculated.
• Water preservation: Preserved 100% of the Piaui Creek source of drinking water for the communities
living around Sigma Lithium.
• Clean renewable energy: Utilizes 100% clean renewable energy for its Greentech Plant via “behind the
meter” supply agreements.
• Biodiesel: Utilizes biodiesel fuel in some of its trucking fleet, with plans to increase to up to 50% by 2025.
• Explosives / ANFO: Decreased explosives load with computerized load simulation strategies.

Further, due to the low carbon content of Sigma Lithium’s products, as well as its environmentally sustainable
production methods, the Company’s carbon footprint was offset with carbon credits purchased from
Carbonext (which are verified through Verra Verified Carbon Standard), making the shipment carbon neutral.
