Sigma Reports 2020 Second Quarter Results and Reaches Pivotal Milestones Towards Construction

VANCOUVER, Sept. 01, 2020 - Sigma Lithium Resources Corp. (“Sigma” or the “Company”) (TSX-V: SGMA) (OTC- QB: SGMLF) reported financial and operating results for the second quarter ended June 30, 2020. The Company reached major milestones despite the challenging circumstances created by the global pandemic and a very poor pricing environment in lithium markets.

Sigma completed raising the equity funding required to build the Grota do Cirilo Project (the “Project”). On August 12, 2020 Sigma closed a non-brokered private placement and has issued 8,285,200 common shares at a price of C$2.15 per share for gross proceeds of approximately US$13.3 million (the “Offering”). The Offering was upsized from US$10.0 million initially announced due to strong institutional investor demand. Sigma also signed a term sheet for a US$45 million senior secured project finance facility with Societe Generale, which is subject to customary closing conditions. These amounts will be complemented by US$ 27 million that remains to be disbursed under a production pre-payment agreement with Mitsui & Co. Ltd. to fully fund the Project.

Sigma also signed with Duro Felguera (“DF”) a contract for front-end engineering design, which includes an agreement for DF to offer Sigma its engineering, procurement and construction (“EPC”) services (the “FEED Contract”) with a multi-currency lump sum turnkey guaranteed maximum price in US Dollars and Brazilian Reais (the “Multicurrency GMP”), structured to capture procurement savings resulting from the 40% devaluation of the Brazilian Real in 2020. Primero Group Americas Inc. was the nominated engineering firm in the FEED Contract. Subsequently, Sigma received a letter of intent from the Spanish export credit agency CESCE to supply financing for up to 85% for the FEED Contract.

The Project will be designed to produce 220,000 tonnes per year of high purity battery grade 6% lithium concentrate in its first phase (the “First Phase of Production”), followed by an additional 220,000 tonnes per year in its second phase estimated to initiate in 2023 (the “Second Phase of Production”), doubling the planned production capacity of the Company to 440,000 tonnes per year.

“The merit for Sigma’s exceptional achievements during these unprecedented times belongs to the entire team. Their unwavering commitment to take Sigma to production and bring economic prosperity to the impoverished Jequitinhonha valley drove them to give their very best and to never relent, even in the most trying moments. Our agile and non-hierarchical corporate culture continued to foster superb collaboration across all areas, providing Sigma with unique speed to simultaneously tackle multiple execution workstreams,” said Ana Cabral-Gardner, Co-Chairman and Chief Strategy Officer of Sigma.

“I would personally like to recognize the outstanding contribution our team continues to make to the success of the project for the benefit of all stakeholders," added Calvyn Gardner, Co-Chairman and CEO of Sigma.

NEXT STEPS FOR SIGMA IN 2020

The Company’s plans for the next four months are as follows:

• Initiate the detailed engineering for constructing the Project’s plant, mine and associated infrastructure for the First Phase of Production, where engineering contractors will:
  • Finalize a selected set of engineering deliverables to achieve 30% engineering definition
  • Advance long lead and critical equipment procurement to “Ready for Award” contract status
  • Advance site preparation (civil works) and complete the contracting strategy for construction
  • Optimize and reduce the contingency applied to the Multicurrency GMP to determine a fixed price “lump sum turnkey cost” for the EPC of the commercial processing plant and associated process infrastructure
  • Obtain a complete and firm proposal for the EPC contract and execute the EPC contract
    
• Following the approval of the study Plano de Aproveitamento Economico (“PAE”) for the Project’s second deposit, Sigma will accelerate the first steps of the Second Phase of Production, which is estimated to come onstream in 2023:
  • Initiate the environmental licensing process by conducting the environmental impact study for the deposit and filing it with the environmental agency in the state of Minas Gerais
  • Finalize a pre-feasibility study for the deposit, validating its economic potential and the estimates for production costs outlined in the PAE using the parameters of Canada’s National Instrument 43-101
    
• Conclude formalizing the binding take or pay agreement with Mitsui & Co. Ltd for the First Phase of Production, increasing it to 160,000 tonnes per year of lithium concentrate.
  
• Although Sigma has secured the funding package for the development of the First Phase of Production, subject to finalizing certain agreements, the Company plans to continue to work closely with the Brazilian financial institutions with which it has been in discussions to access funding to potentially accelerate the Second Phase of Production.

SECOND QUARTER 2020 FINANCIAL RESULTS

Sigma’s financial statements and MD&A for the three and six months ended June 30, 2020 were filed on SEDAR on August 28, 2020.

Selected consolidated financial information is presented as follows:

• The significant reduction in net loss on a year-over-year basis was mainly due to cost saving initiatives by management.
  
• The devaluation of the Brazilian Real led to a foreign exchange gain due to its’ positive impact on Real-denominated liabilities. It also led to a negative cumulative currency translation adjustment, which was added to comprehensive loss. The latter resulted mostly from the devaluation’s negative impact on the value of exploration and evaluation assets, which are held by Sigma’s wholly owned Brazilian subsidiary Sigma Mineracao S.A. (“SMSA”) and are denominated in Brazilian Reais.
  
• At June 30, 2020, the Company’s liabilities consisted mostly of (i) C$2.7 million in payables and accrued interest owed to suppliers, (ii) C$4.0 million in deferred revenue, which was received from Mitsui & Co. Ltd. as an initial disbursement under the abovementioned offtake agreement; and (iii) C$5.5 million in debits with related parties. Debits with related parties included primarily C$2.3 million in the balance and accrued interest of a note payable issued for the acquisition of a remaining 11% interest in SMSA; and C$2.6 million in amounts drawn, fees and accrued interest on a credit facility with the A10 Group (a group of companies owned by certain directors of the company) (the “A10 Credit Facility”).
  
• At June 30, 2020, the company had C$0.15 million in cash and cash equivalents. The A10 Credit Facility, which was set up on November 29, 2019 at US$5 million for a one-year term, had US$3.5 million still undrawn. Also, on June 30, 2020, Sigma’s balance sheet did not reflect the cash inflows and subsequent results of the abovementioned Offering, which was completed in August and had gross proceeds of US$13.3 million.
