SGMA Sigma Lithium Corporation

Sigma Lithium Resources Corporation (“Sigma” or the “Company”) (TSX-V: SGMA) is pleased to announce that it participated in a public symposium held at the Municipal Chamber of Itinga with senior Federal, State and Local Brazilian government officials. The purpose of the symposium was to discuss how to further facilitate and develop the Lithium Value Chain by creating an industrial zone dedicated to the development of the lithium chemical processing in the Jequitinhonha Valley, building on Sigma’s investments in mining lithium in the region.

The public meeting was organized by Federal, State and Municipal senior government officials, including congressmen from various political parties who are representatives in the Jequitinhonha Valley.

Amongst the key participants were the Brazilian Deputy Minister of Mines (Secretary of State for Geology, Mining and Mineral Transformation of the Ministry of Mines and Energy), the Mayors of 17 towns in the Jequitinhonha Valley, key Federal and State Congressmen as well as representatives from the UmVale association and the chambers of commerce of the Jequitinhonha Valley municipalities.

“We are thrilled that our green mining operation has harnessed such deep support from Federal, State and Local Government as well as from key political leaders of different parties and with distinct ideologies”, said Ana Cabral, Sigma’s Chief Strategy Officer.

“The development of local infrastructure could potentially attract chemical industrial companies to the region and create the appropriate business environment for the introduction of the refined chemical processing step of the lithium mineral. Sigma has produced on a pilot scale a pre-chemical 6% battery-grade lithium oxide for use in electric vehicles or energy storage for utilities. With the right industrial infrastructure, such as a gas pipeline, an entire new industry could flourish in the Jequitinhonha Valley to produce the lithium hydroxide chemical, generating significant economic and social development value”, she added.

Amongst the various initiatives discussed were the construction of a gas pipeline in a public-private partnership, a railway network connection and the creation of further business incentives, in addition to those available under the SUDENE initiative.

“This meeting demonstrated the commitment of the Brazilian Government in supporting Sigma and the desire to further develop a new sustainable lithium industrial hub in the Jequitinhonha Valley, one of the poorest parts of Brazil, and bring to the local population jobs, opportunities and economic development”, said Itamar Resende, Sigma’s Director of Sustainability, Institutional and Community Relations. “These initiatives go to the heart of our core purpose and mission, as Sigma was founded on key Environmental, Social and Governance (“ESG”) principles to produce battery-grade lithium concentrate and contribute to the development of the impoverished Itinga, Araçuaí and surrounding municipalities,” he added.

In June, Sigma obtained the environmental licenses for both construction (“LP”) and installation (“LI”) of its Lithium Commercial Production Plant (“Plant”) from the environmental authority of the State of Minas Gerais, the Council of Environmental Policy (“Conselho Estadual de Politica Ambiental – COPAM”) in Brazil. Based on the design being considered under the ongoing feasibility study (“DFS”), the Plant will have the capacity to process 1.8 million metric tonnes of spodumene ore per year from its Grota do Cirilo property. The lithium process design is proprietary and includes DMS technology.

“We are very fortunate to be working in such a business-friendly region and in a country with stable economic, legal and regulatory frameworks. In addition, the Jequitinhonha Valley is a privileged resource-rich low-cost location supported by clean energy from hydroelectric power generation. By fostering the lithium industry, the government authorities and the political parties with representation in the area have a unique opportunity to contribute to a deep transformation of the region, supporting the sustainable development of the communities. Should the Local, State and Government authorities move forward with the construction of a gas pipeline, for example, it would represent a significant advancement and contribute towards the development of a competitive Lithium Value Chain in Brazil,” said Ana Cabral.

Sigma is projected to produce 220,000 tonnes per year of high-quality battery-grade 6% lithium oxide concentrate, or spodumene, with one of the lowest levels of impurities in the world, which according to the studies completed so far will likely be one of the lowest-cost lithium mine operations globally. Once production is under way, Sigma stands to become one of the largest producers of lithium in the Americas. The Company also has the option to double capacity to produce 440,000 tonnes per year, subject to completion of all related studies and assessments.
