SIGMA LITHIUM ACHIEVES RECORD PEAK PRODUCTION
OF 890 TONNES PER DAY, EQUIVALENT TO ANNUALIZED
320,000 TONNES PER YEAR
HIGHLIGHTS
Achieves Operational Targets
• Sigma Lithium announces that its Greentech Plant has reached record daily peak production
of 890 tonnes of Triple Zero Green Lithium, equivalent to annualized production of 320,000
tonnes
• The Company is on track to achieve annual 2023 production guidance of 130,000 tonnes
• The Company has exceeded the design utilization rate of 85%, running at 88%
• Greentech Plant’s throughput has evolved to 100% design capacity
•
SAO PAULO, BRAZIL – (Oct. 2 , 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, responsibly
sourced chemical grade lithium concentrate, announces that its Greentech Plant has reached record
daily peak production of 890 tonnes, equivalent to annualized production of 320,000 tonnes of Triple
Zero Green Lithium at battery grade with 5.5% of lithium oxide.
Therefore, as planned, the Company demonstrates it remains on track to achieve annual 2023
production guidance of 130,000 tonnes of Triple Zero Green Lithium.
Sigma Lithium has successfully ramped up its Greentech Plant to enable it to operate at 100% of
design nameplate throughput capacity of annualized production of 270,000 tonnes of Triple Zero
Green Lithium.
Achieved Operational Targets
Achieving these targets demonstrates the excellent performance of the Greentech Plant and its
tailings dry-stacked circuit in synchronicity with Dense Medium Separation (DMS).
• The Company has exceeded the design utilization rate of 85%, running at 88%.
• Throughput has evolved, as planned, from 75% throughput capacity at the end of July 2023
to 100% design capacity, as of Sept. 30, 2023.
o DMS cyclones operating consistently at 200 t onnes/hour (maximum capacity is 230
tonnes/hour)
• Greentech Plant global recoveries have been tracking in line with design.
o The Company has been calibrating “down” the concentrate grade from 5.9% Li2O
lithium concentrate.
Sigma Lithium’s state -of-the-art Greentech Plant is the first lithium plant in the world to produce
chemical grade lithium concentrate without a tailings dam and with 100% reuse of the water utilized
in the processing.
• With 100% dry -stacked tailings and the absence of hazardous chemical products in
processing the lithium, the Company is minimizing the risk of water and soil contamination.

• Actively contributing to the preservation of water and biodiversity (ecosystems of creeks,
and “caatinga” vegetation in the region).
Sigma Lithium has been demonstrating high adherence to the reserve reconciliation:
• Actual ore grade and volumes mined are in line with long term geological and mining models
reserves stated at the Company’s NI 43101 Technical Report.
Achievement of these milestones is due to the dedication and commitment of the on-site Sigma
Lithium team, led by Director of Mining Reinaldo Brandao and Director of Processing Keith Prentice.
Over the past three months of their on-site supervision, Reinaldo and Keith have led the operational
ramp-up of the Greentech Plant, including the re-engineering of the tailings dry-stacking/water
reusage circuit.
ABOUT SIGMA LITHIUM
Sigma Lithium (NASDAQ: SGML, BVMF: S2GM34, TSXV: SGML) 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 Triple Zero Green Lithium from its
Grota do Cirilo Project in Brazil. Phase 1 of the project is expected to produce 270,000 tonnes of Triple
Zero Green Lithium annually (36,700 LCE annually). If it is determined to proceed after completion of
an ongoing feasibility 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 Triple 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.

legislation, including but not limited to statements relating to timing and costs related to the general business and
operational outlook of the Company, the environmental footprint of tailings and positive ecosystem impact relating
thereto, donation and upcycling of tailings, timing and quantities relating to tailings and Green Lithium, achievements
and projections relating to the Zero Tailings st rategy, achievement of ramp -up volumes, production estimates and
the operational status of the Groto do Cirilo Project, and other forward -looking information. All statements that
address future plans, activities, events, estimates, expectations or developments that the Company believes, expects
or anticipates will or may occur is forward -looking information, including statements regarding the potential
development of mineral resources and mineral reserves which may or may not occur. Forward -looking information
