Sigma Lithium advances construction to 25% and announces positive regulatory updates.

PHASE 1 CONSTRUCTION UPDATE

  • Sigma Lithium remains on track to deliver its battery grade high purity sustainable lithium and initiate cash flow generation in the near-term (construction progress footage can be viewed here).  Approximately 25% of total construction completed.  Phase 1 construction remains on schedule and on budget for commissioning to commence by December 2022.  The Company is planning for approximately 600 professionals working on site, when the pace accelerates during peak civil construction and electromechanical assembly in October and November 2022; and reached significant completion level of 65% for the final 2D drawings of the construction
  • Electromechanical assembly of the equipment for the Production Plant has commenced at respective suppliers manufacturing sites.  Equipment is expected to begin arriving on site for installation towards the end of July.
  • The following key workstreams are currently underway: Civil construction of foundations for the installation of the equipment of the Production Plant (crushing plant area, scalping screening and Greentech Plant); Civil construction of the run of mine (“ROM“) pad and ROM wall; Construction of the Company’s own high voltage substation on site; and Fabrication of platework and steel structure on site.
  • To date, the following construction workstreams have been 100% completed: Earthworks necessary for construction of foundations for the Production Plant; Production Plant site’s protective drainage (channels and pipes); Sump area construction; and Detour road improvements (bypass of the municipal road around the Project).

LITHIUM INDUSTRY REGULATORY UPDATE IN BRAZIL

  • On July 5, 2022, the Brazilian Government issued a presidential decree (the “New Lithium Decree”) allowing unrestricted trade of any products containing lithium, updating the regulatory framework of the sector. The decree eliminates the requirement to solicit quotas and export authorizations by the nuclear authority, positively modernizing and deregulating the entire lithium sector for the energy transition and significantly increases the competitiveness of Brazil for global investments.  It creates the regulatory conditions for Brazil to extend its leadership in environmentally and socially sustainable pre-chemical lithium concentrate further downstream into refined chemicals and cathode precursors / cathode paste, also affected by the export quotas and authorization requests to the nuclear authority.  

ENVIRONMENTAL LICENSING UPDATE

  • On June 27, 2022, the Company obtained its requested extension of its current environmental licenses to allow for the simultaneous mining of the north pit and the south pit of the Phase 1 deposit.  This enables the Company to plan a significant expansion of the production capacity in Phase 2 by increasing the area where the dry stacking of the tailings of the Production Plant is allowed.  The expansion also makes the municipality of Araçuaí (where the south pit is located) eligible to receive royalties from Sigma Lithium’s production, sharing them with Itinga where the north pit and the Production plant are located.
  • The Company’s ESG-centric strategy guided the decision to conduct the simultaneous mining of the north pit and the south pit of the Phase 1 deposit.

CORPORATE UPDATES

  • Sigma Lithium received overwhelming support at its annual general shareholder meeting (“AGM“) held on June 30, 2022.  Approximately 75% of the outstanding shares were represented at the AGM.  All Directors of the Company were re-elected by overwhelming votes.  Over 98% of the minority shareholder shares represented at AGM were voted FOR the Amendment of the Equity Incentive Plan.  This amendment enables the Company to attract and retain the operating team members who will transition Sigma Lithium into a major global producer.
  • Sigma Lithium was featured in a “View from C-Suite” interview produced by the TMX Group. Film produced by the TMX Group can be viewed here.

SIGMA Lithium Corporation (“Sigma Lithium” or the “Company”) (NASDAQ: SGML, TSXV: SGML), dedicated to powering the next generation of electric vehicles with environmentally sustainable and high-purity lithium, to provide an update on construction at its wholly owned Grota do Cirillo project (the “Project” or “Grota do Cirilo”), as well as provide a regulatory update and report the results of the voting at its AGM held on June 30, 2022.

Ana Cabral-Gardner, Co-CEO and Co-Chairperson of Sigma Lithium, said:

We are honored by our shareholders’ continued support and the overwhelming approval of all voted resolutions at our AGM held on June 30, 2022.

“”We remain focused on establishing Sigma Lithium as one of the world’s largest lithium producers, significantly progressing towards positive cash flow when delivering Battery Grade Sustainable Lithium in the near term.”

“Our operating team has been consistently delivering all the execution milestones of the Project’s construction and licensing, positioning the Company to potentially participate as a producer in what may be one of the most favorable lithium markets of all time.”

Calvyn Gardner, Co-CEO and Co-Chairperson of Sigma Lithium added:

We are pleased to provide an update on our significant construction progress at Grota do Cirilo, as we continue to rapidly advance Phase 1 Plant construction on schedule and on budget, with approximately 25% of total construction completed.

“The continuous advance of final construction drawings towards 65% completion also allows us to plan for the total amount of bulk construction material to be utilized, potentially extending our management of our supply chains.”

PHASE 1 CONSTRUCTION UPDATE

Sigma Lithium is pleased to report significant advancement of construction at its Phase 1 Production Plant and infrastructure areas, establishing operational readiness and supporting ongoing operations. The Company continues to rapidly progress construction activities and has issued more than 30 purchase orders for critical equipment as of July 2022.

To date, the following construction workstreams have been 100% completed:

  • Earthworks necessary for construction of foundations for the Production Plant;
  • Production Plant site’s protective drainage (channels and pipes);
  • Sump area construction; and
  • Detour road improvements (bypass of the municipal road around the Project).

Electromechanical assembly (including mainframes for the primary crusher, DMS plant and other infrastructure) has commenced offsite, and the Company expects equipment to begin arriving towards the end of July.

The construction team is currently focused on completing the following workstreams:

  • construction of equipment foundations for the crushing, scalping screening and DMS areas (rebar and pouring concrete);
  • construction of the ROM pad and ROM wall;
  • construction of the Project’s HV substation;
  • electromechanical assembly; and
  • platework and steel structure fabrication.

Additionally, the Company has progressed detailed engineering alongside construction activities, with approximately 65% of overall detailed engineering completed as of July 2022. Refer to Table 1 below for a breakdown of detailed engineering progress.

Table 1: Detailed Engineering Progress Summary

As a result of the advancement in completion to 65% of the construction drawings to date, Sigma Lithium estimates that the following amounts of materials will be utilized in the construction:        

  • Concrete: 5,950 m³
  • Mechanical and Electrical Equipment: 2,130 tonnes
  • Steel Structure: 1,050 tonnes
  • Piping: 113 tonnes
  • Piping Polyethylene: 12,400 linear meters
  • Instruments: 947 units
  • Instruments and Electrical Cables: 105,000 linear meters

ENVIRONMENTAL LICENSING UPDATE

The Company obtained the requested extension of its current environmental licenses for both construction (“LP”) and installation and commissioning (“LI”) from the environmental authority of the State of Minas Gerais (the “LP/LI Environmental License”), the Council of Environmental Policy (“Conselho Estadual de Política Ambiental” or “COPAM”) in Brazil.

  • The extension allows for the simultaneous mining of the north pit and the south pit of the Phase 1 deposit; and
  • The extension also allows for the Company to increase the area utilized for the dry stacking of the tailings of the Greentech Production Plant and thus plan a significant expansion of the production capacity in a Phase 2.

The south pit of Phase 1 mine was designed to:

  • have the lowest possible environmental impact by preserving the Piaui creek; and
  • extend the socioeconomic return of the Company to Aracuai, where the south pit of the deposit was located.

The decision to conduct the simultaneous mining of the north pit and the south pit of Phase 1 by the Company was guided by the Company’s ESG-centric strategy, enabling the municipality of Araçuaí (where the south pit is located) to also be entitled to receive part of the CFEM government royalty.

  • CFEM royalties were previously restricted to the municipality of Itinga, where the north pit is located.
  • As a result, this extension of the environmental license enables the Company to allocate significant royalty payments to BOTH municipalities, meeting SDG # 16 (Peace, Justice and Strong Institutions).

An operating license (“LO“) is required for the commercial operations, when external sales of the products are conducted.

  • The LO in Brazil is only granted once the construction and installation of the Project is completed, as it follows a final inspection by SUPPRI of both First Mine and Production Plant.
  • Therefore, as the Project is in construction the Company does not yet have an LO.

On June 27, 2022, COPAM issued a dual LP and LI Certificate No. 4497, for a period of 6 years expiring on June 24, 2028.

REGULATORY UPDATE

On July 5, 2022, the Brazilian Government issued presidential decree number 11.120 (the “New Lithium Decree“) fully revoking both presidential decree number 2.413 of December 4, 1997, as well as presidential decree number 10.577 of December 14, 2020.

The New Lithium Decree allows for unrestricted trade of any products containing lithium:

  • Eliminates the requirement for quotas and authorizations by the nuclear authority for foreign trade activities, positively deregulating the lithium sector.
  • Significantly increases the competitiveness of Brazil for global investments in the lithium supply chain.
  • Includes chemicals and products containing lithium chemicals and refined lithium chemicals, such as cathode precursors and cathode paste.

Ana Cabral-Gardner, Sigma Lithium co-CEO says: 

The New Lithium Decree is a significant positive step for Brazil to modernize and further integrate the country lithium sector into global lithium supply chains.

“It creates the regulatory conditions for Brazil’s to extend its leadership in environmentally and socially sustainable pre-chemical lithium concentrate further downstream into refined chemicals and cathode precursors.” 

“Brazil’s large reserves of natural gas offshore and abundant and inexpensive renewable energy provide the perfect “Scope 2” conditions for low carbon “Scope 1″ downstream industrial facilities in the lithium supply chain.”

AGM VOTING RESULTS

Sigma Lithium received overwhelming support from its shareholders at its AGM held on June 30, 2022, with all resolutions passed by a vote of the Company’s shareholders.

  • Shareholders of approximately 75% of the outstanding shares were represented at the AGM.

Over 98% of the minority shareholder shares represented at the AGM were voted for the amendment of the equity incentive plan.

  • Enabling the Company to attract and retain the operating team members who will transition Sigma Lithium into a major global producer.
