SIGMA Lithium Resources Corporation (“Sigma”

or the 

“Company”) (TSXV: SGMA) (OTC-QB: SGMLF)

 is pleased to announce that it intends to complete a non-brokered private placement of up to 7,500,000 common shares of the Company (“

Common Shares

”) to be issued at a price of C$4.00 per Common Share for aggregate gross proceeds of up to C$30 million (the “

Offering

”). Institutional investors, including leading global investors focused on ESG & sustainability, are expected to comprise the majority of the investors in the Offering. The closing of the Offering is subject to customary conditions, including the receipt of all necessary approvals, including the approval of the TSX Venture Exchange (the “

TSXV

”).  

XP Investments US LLC, Cormark Securities Inc. and National Bank Financial Inc. acted as financial advisors to the Company and may receive a finder’s fee in respect of certain orders. This compensation will be comprised of (i) cash fees of up to 6% of the proceeds from subscribers introduced by finders and (ii) such number of warrants as is equal to up to 6% of the Common Shares purchased by such introduced subscribers (each such warrant entitling the finder to acquire one Common Share at an exercise price of C$4.00 per share and exercisable for one year after closing of the Offering). Other parties, including the A10 Group, shall also receive a finder’s fee in connection with the Offering.

In this regard, the Company has entered into an agreement with the A10 Group to provide services in respect of the Offering, and A10 Group will be entitled to finder’s compensation for purchases by subscribers it introduces.

The Company intends to use the net proceeds of the Offering as outlined below and for general corporate purposes. The expected specific uses of net proceeds are:

1. To fund the workstreams added in December 2020 aimed at upsizing the Grota do Cirilo lithium project (the “Project”), solidifying Sigma’s unique market leadership as a future supplier of “low-carbon” high-purity 6% battery-grade lithium concentrate, as set out in the December 7, 2020 press release “Sigma is Awarded Development Bank Credit Line on ESG Attributes and Reports Third Quarter Results”, under the section “Operational and ESG Highlights”:
   • Development of Phase 2 production (the Barreiro deposit) planned for 2023: the preparation of a pre-feasibility study (and subsequently a feasibility study) to update the technical report of the Project titled “Grota do Cirilo Lithium Project, Araçuaí and Itinga Regions, Minas Gerais, Brazil, National Instrument 43-101 Technical Report on Feasibility Study Final Report” with an effective date of September 16, 2019 (the “Feasibility Study Report”) to include Phase 2 in addition to Phase 1 (the development of the Xuxa deposit).
   • Pre-development of Phase 3 production planned for 2024-2025: (i) a 20,000-meter diamond drilling programme aimed at adding mineral resources in line with National Instrument 43-101 criteria; and (ii) the preparation of a preliminary economic assessment study, which is also to be used to update the Feasibility Study Report.
   • Funding an ongoing comprehensive set of environmental and social programs established by the Company, which aims to implement actions to proactively mitigate, prevent, control and compensate for the environmental impacts that could eventually be caused by the mining activity to be carried out by Sigma. The Company designed these programs based on the United Nations Sustainable Development Goals – UN-SDGs. 
2. In order to enhance Sigma’s financial flexibility during construction and increase the the maximum amount that could be drawn under the Company’s project finance facility with Société Générale (“Project Finance”) from US$45 million to US$50 million, the Company plans to direct US$5 million from the proceeds of the Offering to its savings account at National Bank, adding to the US$10 million currently reserved as the equity component of the Project Finance. This would bring the total equity set aside by the Company for the Project Finance to US$15 million. This follows the signing of a term sheet for the Project Finance in June 2020 (June 29, 2020 press release “Sigma Announces US$45 Million Project Finance Facility with Societe Generale”).

Certain principals of the A10 Group are directors, officers or indirect significant shareholders of the Company, such that the arrangements with the A10 Group in respect of the Offering is a related party transaction for purposes of Multilateral Instrument 61-101 Protection of Minority Securityholders in Special Transactions and Policy 5.9 of the TSXV (which incorporates such Multilateral Instrument by reference). These arrangements are exempt from the formal valuation and minority shareholder approval requirements of such Multilateral Instrument and TSXV Policy because the value of the transaction and the compensation are below 25% of the Company’s market capitalization. The arrangements with the A10 Group were considered and unanimously approved by each of the directors of the Company unrelated to the A10 Group.

The Common Shares to be issued under the Offering will also be sold to United States buyers on a private placement basis pursuant to an exemption from the registration requirements in Rule 144A of the United States Securities Act of 1933, as amended (the “1933 Act”), and other jurisdictions outside of Canada provided that no prospectus filing, or comparable obligation arises.

The Offering is scheduled to close on or about February 10, 2021 and is subject to certain conditions including, but not limited to, the receipt of all necessary approvals, including the approval of the TSX Venture Exchange and the securities regulatory authorities.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the securities in any state in which such offer, solicitation or sale would be unlawful. The securities being offered have not been, nor will they be, registered under the 1933 Act and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the 1933 Act, as amended, and the application of state securities laws.

This news release does not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of Common Shares under the Offering, in any jurisdiction in which such offer, solicitation or sale would be unlawful.
