VANCOUVER, CANADA -- (June 22, 2022) - SIGMA Lithium Corporation ("Sigma Lithium" or the "Company") (NASDAQ: SGML, TSXV: SGML), dedicated to powering the next generation of electric vehicles with environmentally and socially sustainable high-purity lithium, is pleased to announce an approximate 50% increase of its total estimated mineral resource to 85.7 million tonnes (from previous 58.9 million tonnes), further demonstrating the robust scale of the Project.
The Company completed an NI 43-101 mineral audit by SGS Geological Services (“SGS”) at its Phase 3 NDC deposit (“Phase 3 Deposit”) of the Project with 26.8 million tonnes of high grade 1.49% lithium oxide. NDC is an “open pit” deposit located close to the Project’s Phase 2 feasibility study stage Barreiro deposit.
The Phase 3 mineral resource estimate of 26.8 Mt is comprised of:
| · | 23.3 Mt of Measured and Indicated mineral resources grading at 1.49% Li2O; and |
| · | 3.5 Mt of Inferred mineral resources grading at 1.48% Li2O. |
“We are delighted to announce this substantial increase in the Company’s estimated mineral resource as a result of Phase 3, solidifying the Project’s significant scale as the largest mineral lithium project in the Americas. This 50% increase of its mineral resource underscores its robust organic growth profile. We have been advancing our construction of the Phase 1 operation at a rapid pace and remain focused on delivering Battery Grade Sustainable Lithium following the commissioning of our Greentech plant at the end of 2022. Phase 1 Plant construction continues to advance on schedule and on budget, with civil engineering under way and construction of key infrastructure items continuing in June”, says Calvyn Gardner, Co-CEO of Sigma Lithium.
Ana Cabral-Gardner, co-CEO of Sigma Lithium adds: “More importantly the high quality of the Phase 3 mineral resource might potentially enable Sigma Lithium to maintain high production yields utilizing a similar environmentally sustainable Greentech plant to the one currently in construction for Phase 1, while continuing to increase our production profile to help enable the electric vehicle revolution and broader energy transition. The scale of Sigma Lithium’s total mineral resources further highlights the Company’s strategic relevance.”

PHASE 3 MINERAL RESOURCE NI 43-101
The Phase 3 mineral resource estimate is based on 18,483 m of drilling completed during the final quarter of 2021 and first quarter of 2022. Additional drilling is expected to be completed at NDC in 2022 to conclude the pre-feasibility study and pursue the conversion of Measured & Indicated mineral resources into Proven & Probable mineral reserves and further increase the mineral resource estimate. NDC remains open to the north, south and at depth with the deepest drill hole reaching 350 m.
The NDC pegmatite is hosted in a biotite-quartz schist (similar to the Phase 2 Barreiro deposit) with a strike length of 1,600 m at a width of 200 m and thickness between 15 to 30 m.
A Phase 3 PEA is expected to be completed during the summer of 2022 to further evaluate the potential for a Phase 3 of production in addition to the 531,000 tpa (72,200 tpa LCE) of Battery Grade Sustainable Lithium estimated in the Phase 1 & 2 technical report announced on May 26, 2022.
Refer to Table 1 and 2 below for a breakdown of the maiden NDC mineral resource estimate and Sigma Lithium’s updated consolidated Project mineral resource estimate. On top of the NDC mineral resource, the combined table includes the 2019 mineral resource estimates of Xuxa, Lavra do Meio and Murial having an effective date on January 10, 2019 and the 2021 Barreiro mineral resource estimate having an effective date of June 2, 2021. The mineral resource estimates detail can be found in the most recent technical report posted on SEDAR on May 25th, 2022.

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 contained herein is based on certain assumptions regarding, among other things: general economic and political conditions; the stable and supportive legislative, regulatory and community environment in the jurisdictions where the Company operates; anticipated trends and effects in respect of the COVID-19 pandemic and post-pandemic; the military conflict in Ukraine and related sanctions; demand for lithium, including that such demand is supported by growth in the electric vehicle market; the Company’s market position and future financial and operating performance; the Company’s estimates of mineral resources and mineral reserves, including whether mineral resources will ever be developed into mineral reserves; and the Company’s ability to develop and achieve production at its mineral projects. Although management believes that the assumptions and expectations reflected in the forward-looking information are reasonable, there can be no assurance that these assumptions and expectations will prove to be correct. Forward-looking information inherently involves and is subject to risks and uncertainties, including but not limited to that the Company may not develop its mineral projects into a commercial mining operation; the market prices for lithium may not remain at current levels; and the market for electric vehicles and other large format batteries currently has limited market share and no assurances can be given for the rate at which this market will develop, if at all, which could affect the success of the Company and its ability to develop lithium operations. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking information. The Company disclaims any intention or obligation to update or revise any forward-looking information, whether because of new information, future events or otherwise, except as required by law.
