The increase is also said to increase low-cost lithium production growth at the mine, enabling a third or fourth processing facility to be added to the operation.
“The entirety of this Reserve balance is available near surface, allowing to the Company to efficiently mine through low cost, open pit, mining practices, avoiding the operational risks and higher levels of water use associated with underground activity,” commented Reinaldo Brandao, Co-General Manager of Sigma Lithium.
Sigma Lithium last traded at $23.00 on the TSX Venture.
