Sigma Lithium to reach 270K tonnes of Triple Zero Green Lithium in Q3

SIGMA Lithium Corporation provides an operational and ESG update following the first shipment of its Triple Zero Green Lithium in July. Ramp-up of Phase 1 production continues to advance on schedule and the company remains on track to achieve 2023 production guidance of 130,000 tonnes of Triple Zero Green Lithium with consistent annualized production of 270,000 tonnes of Triple Zero Green Lithium expected to be achieved by the end of Q3-2023. Recent positive operational achievements include operating the Greentech Plant at approximately 85% utilization rates, which is commensurate with the designed ramp-up schedule. Additionally, the Company successfully calibrated the dry stacking circuit belt filter of the Greentech Plant in July 2023, which continues to provide positive results and enabled the Company to achieve 95% of nameplate throughput capacity in August month-to-date and to achieve several consecutive days of design nameplate recovery rates of 65%. As a result of this operational success, Sigma Lithium recently achieved record daily production of 846 tonnes of Triple Zero Green Lithium, which met expected specifications. As the Greentech Plant continues to maintain a steady pace of acceleration and is on pace to reach consistent nameplate production in Q3 2023, Sigma Lithium expects to have its second shipment of 15,000 tonnes of Triple Zero Green Lithium by the end of August, 30,000 tonnes of Triple Zero Green Byproducts by mid-September and 18,000 tonnes of Triple Zero Green Lithium by the end of September. In addition to the the successful ramp-up activities with the current plant equipment, as a contingency plan the company expects to install a Metso LAROX filter in order to mitigate any potential future bottlenecks.
