SAO PAULO, July 1, 2024 /PRNewswire/ -- Sigma Lithium Corporation (NASDAQ: SGML) (BVMF: S2GM34) (TSXV: SGML), a leading global lithium producer dedicated to powering the next generation of electric vehicles with carbon neutral, socially and environmentally sustainable lithium concentrate, is pleased to announce it completed the sale of its 10^th shipment of 22,000t of Quintuple Zero Lithium at a premium floating price of 8.75% of LME Lithium Hydroxide quoted at LME (CIF Shanghai basis).

The 22,000 tonne shipment is scheduled for departure in early July, maintaining the operational cadence of delivering its Quintuple Zero Green Lithium to customers on a reliable basis.

• On June 30, 2024, Sigma concluded a FOB export sale at Victoria Port's warehouse for 17,200 tonnes of Sigma's Quintuple Zero Lithium concentrate with the additional 4,800 tonnes balance for a total of 22,000 tonnes to be shipped in early July.

Sigma Lithium continues to refine its commercial strategy for its Quintuple Zero Lithium. The Company has experienced robust demand for its lithium concentrate, which delivers measurable cost savings to its customers as a result of the product's superior physical and chemical properties.

CEO and Co-Chairperson, Ana Cabral, notes: "Over our first 11 months of operations, Sigma Lithium has cemented its reputation as a sustainable and reliable producer, consistently executing large scale quasi-monthly deliveries of our high-quality Quintuple Zero Green Chemical Grade Coarse Lithium."

"Over these 10 shipments, we've established a solid base of clients who enjoy measurable "value-in-use", and the 20-30% cost savings provided by our unique product's high purity, low mica contaminants and coarse particles (over 6.5mm). On top of that, we're supplying our clients with the only zero carbon lithium in the industry and not charging a penny extra for it. In other words we're not receiving a green premium."

Sigma Lithium Commercial Director Catarina Noci adds: "We continue to pursue a premiumization strategy for our product, while floating our formula based on the LME lithium hydroxide price to share the lithium pricing risk with our clients, providing battery makers and auto makers price predictability. Our strategy is to work with our large commercial partners to monetize their tangible cost savings into a "high quality premium". Our product becomes increasingly valuable to our customers when end-users who rely on tolling agreements with non-integrated refiners experience tighter operating conditions."
