(Kitco News) - Sigma Lithium (NASDAQ:SGML, TSXV: SGML) said today it concluded the crushing circuit ("dry module") commissioning successfully at its Grota do Cirilo project in Brazil by producing a continuous sequential batch of crushed lithium material.
Sigma Lithium added it also concluded the commissioning of the system that will pump water from Rio Jequitinhonha 6km away to the sewage treatment plant to clean the water of its solid residues, making it suitable for the Greentech Plant.
"Commissioning of the Greentech Plant continues ahead of schedule and on budget," the company said in a statement.
Importantly, the company noted it remains on track to commence commercial production in April 2023, and expects to start generating cash flow in the second quarter of this year, "producing battery grade high purity environmentally and socially sustainable lithium concentrate."
Sigma Lithium also announced the commencement of detailed engineering and Capex FEL-3 costing of the Greentech Plant expansion from 270,000 tpa to 766,000 tpa of battery grade sustainable lithium.
Sigma Lithium is currently commissioning its wholly owned Grota do Cirilo Project in Brazil. Phase 1 of the project is to produce 270,000 tonnes annually (36,700 LCE annually).
If it is determined to proceed, Phase 2 & 3 of the project are expected to increase production to 766,000 tonnes annually (or 104,200 LCE annually) of battery grade sustainable lithium concentrate in a state-of-the-art Greentech lithium plant that uses 100% renewable energy, 100% recycled water and 100% dry-stacked tailings.
