SIGMA LITHIUM ANNOUNCES COMPLETION OF
CRUSHING CIRCUIT AND PUMP WATER SYSTEM
COMMISSIONING, REMAINS ON TRACK FOR PRODUCTION IN
APRIL, STARTS DETAILED ENGINEERING FOR PLANT
EXPANSION FROM 270,000 tpa TO 760,000 tpa
HIGHLIGHTS OF GREENTECH PLANT COMMISSIONING
• Concluded the crushing circuit (“dry module”) commissioning successfully by producing a
continuous sequential batch of crushed lithium material.
o Timeline on schedule as announced on December 20, 2022 and on January 23, 2023 at
the start of commissioning the dense medium separation circuit (“DMS”) of the
production plant (the “Greentech Plant”).
o Lithium material crushing footage can be viewed at HERE and HERE.
• Sigma Lithium also concluded the commissioning of the system that will pump water from Rio
Jequitinhonha 6km away to the sewage treatment plant to clean the water of its solid residues,
making it suitable for the Greentech Plant.
o Timeline on schedule as announced on December 20, 2022 and on January 23, 202 3.
• Commissioning of the Greentech Plant continues ahead of schedule and on budget.
• The Company remains on track to commence commercial production in April 2023 , and expects
to start generating cash flow in the second quarter of this year, producing battery grade high
purity environmentally and socially sustainable lithium concentrate (“ Battery Grade Sustainable
Lithium”).
HIGHLIGHTS OF GREENTECH PLANT CAPACITY EXPANSION (PHASES 2 & 3)
• Sigma Lithium also announces the commencement of detailed engineering and Capex FEL-3
costing of the Greentech Plant expansion from 270,000 tpa to 766,000 tpa of Battery Grade
Sustainable Lithium.
VANCOUVER, CANADA – (February 13, 2023) – SIGMA Lithium Corporation (“Sigma Lithium ” or the
“Company”) (NASDAQ: SGML, TSXV: SGML), dedicated to powering the next generation of electric vehicles with
Battery Grade Sustainable Lithium, today announced the production of continuous sequential batches of crushed
lithium material and completion of commissioning of its crushing circuit of the Greentech Plant, on schedule and
in line with guidance provided previously on December 20, 2022 and on January 23, 2023.
Additionally, the Company is pleased to announce the commencement of Greentech Plant expansion (Phase 2 &
3) detailed engineering and capital expenditure costing at FEL-3 precision by obtaining firm quotes from suppliers.
The Greentech Plant expansion is expected to increase run-rate production from 270,000 tpa to 766,000 tpa of
Battery Grade Sustainable Lithium.
“Reaching this critical milestone of concluding commissioning of the crushing module of the Greentech Plant is a
tremendous achievement of our execution team. What drives us at Sigma Lithium is the larger purpose to leave a
legacy of prosperity at Vale do Jequitinhonha in Brazil. We are inserting Brazil in the global battery materials supply
chain through the front door, producing an environmentally and socially sustainable lithium that will be building the

next generation of electric vehicles with materials produced with the same ethos of its customers ” said Ana
Cabral-Gardner, Sigma Lithium CEO and Co-Chair.
“Our community, neighbours and the municipalities at Vale do Jequitinhonh a have been our stalwart supporters
since inception. The Minas Gerais Government and the Federal Government have been driving progress in the
country and the state by creating a modern regulatory environment for lithium and for environmental licensing ,
comparable to the best countries in the industry such as Australia. As a result, more than seven new lithium
exploration publicly traded companies, adhering to Australian or Canadian high standards of governance have
been established in the region last year, mentioning Sigma Lithium as their beacon. Ushering a new era for Vale
do Jequitinhonha and transforming it into the Vale of Lithium”. She adds.
