Sigma Lithium's first trucks loaded with Battery Grade High Purity Sustainable Lithium ("Green Lithium") and its dry stacked, zero chemicals high purity tailings ("Green Tailings") successfully arrived at the Company's two separate warehouse locations at Vitoria Port
A total of 10 trucks were loaded on schedule this week, starting on Monday, April 24:

4 trucks with approximately 146 tonnes of Green Lithium
6 trucks containing Green Tailings to be upcycled into Battery Grade Lithium Concentrate

On Wednesday, April 26, the trucks started to arrive at Brazil's Vitoria Port, recently selected for its enhanced logistics capabilities

Vitoria Port is best suited for Sigma Lithium's increasing export operational scale, resulting from the successful market receptivity for its Green Tailings

The Company remains on track to achieve full Phase 1 production capacity of 270,000 tonnes per annum by July 2023

VANCOUVER, BC, April 27, 2023 /PRNewswire/ -- SIGMA Lithium Corporation ("Sigma Lithium" or the "Company") (NASDAQ: SGML, TSXV: SGML), dedicated to powering the next generation of electric vehicles with Green Lithium, announced that it has successfully loaded the first trucks for its inaugural shipment of Green Lithium and tailings containing low grade concentrate from its Grota do Cirilo project in Brazil.

The loading consisted of two trucks with approximately 74 tonnes of Green Lithium, and three trucks with tailings, approximately 116 tonnes in total. The loading process was completed quickly, with each truck taking approximately five minutes to load. The logistics chain beginning in the plant in Araçuaí, which is specially designed to handle Sigma Lithium's concentrate and tailings operations simultaneously, has proven effective and the trucks' loading and transition were completed quickly and seamlessly from plant to warehouse. The two products are being stored in a segregated manner and each one has a tailored logistical approach, ensuring safe transport and accurate forwarding of the material. The trucks arrived at the warehouses in Brazil's Vitoria Port on Wednesday for discharge.

Product shipment volume continues to increase daily and is on track to achieve the expected ramp-up volumes.

Ana Cabral-Gardner, Sigma Lithium CEO and Co-Chairperson, congratulates the Sigma Lithium team and reiterates plans to complete the first shipment in May.

"We are thrilled to achieve this milestone, which demonstrates our continued progress and rapid ascent to become one of the world's largest lithium producers," said Cabral-Gardner. "We are proud that our project will enable Brazil to be a leader in the energy transition as a key supplier of raw materials that can be mined and processed in a sustainable way for our environment and our communities. We look forward to providing a further update at our next earnings announcement as we continue to meet our production targets and ramp up to full production capacity."
