SIGMA LITHIUM INCREASES PROVEN & PROBABLE OPEN PIT
MINERAL RESERVE BY 40% TO 77Mt EXTENDING OPERATIONS
TO 25 YEARS

 

 

HIGHLIGHTS

 

·

Sigma Lithium is increasing its Proven and Probable Reserve balance by 40% to 77.0 million tonnes from 54.8 million tonnes.

 

o

The entirety of this mineral Reserve balance is feasible through low-cost, open pit, mining operations, consolidating the Company’s position as a low-cost producer of Quintuple Zero High Purity Lithium materials.

 

·

Increased Proven and Probable Reserves lengthens the duration of Sigma’s integrated industrial-mining operations to an estimated 25 years at two phases of processing capacity at 520,000 tonnes/year.

 

 

São Paulo, Brazil – (May 08, 2024) – Sigma Lithium Corporation (“Sigma Lithium” or the “Company”) (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, announces it is increasing its Proven and Probable Mineral Reserves at its 100% owned Grota do Cirilo operation at Vale do Jequitinhonha by 40%, equivalent to 22.2 million tonnes.

 

The Company is increasing its consolidated Proven and Probable Reserve balance to 77.0 million tonnes at 1.40% lithium oxide (Li₂O) from 54.8 million tonnes at 1.44% prior. The increase occurs within the combined phases 3 and 4 mines, resulting in a lengthening of the duration of its integrated mining and beneficiation operations to an estimated 25 years at two lines of processing capacity totaling 520,000 tonne per annum (includes the second industrial line of 250,000 tonnes currently under construction).

 

The increased mineral Reserve balance enables meaningful opportunities for continued low-cost lithium production growth at Sigma Lithium’s Grota do Cirilo operations by supporting a third and potentially fourth processing facility, or a longer operating life at the Company’s currently planned lithium throughput. As the available balances show consistent minerology and are available through open pit mining operations, the Company expects to maintain its current, Phase 1, low operating cost model as it expands into additional phases.

 

This increase in mineral Reserves does not represent the full extent of the conversion of mineral Resources as announced by the Company on January 31, 2024. Sigma Lithium continues to execute the mineral and geological development work in order to further convert its Resources into Reserves over time.

 

“The mineral Reserve update comes as a result of months of detailed specialized geo statistical technical modeling work from the mining team to process and optimize our mine plans around the increased resource data” says, Reinaldo Brandão, Co-General Manager and head of Mining Operations. He continued, “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.”

 

Iran Zan, Co-General Manager and head of Geology notes, “An increase of 22.2 million tonnes to our Reserve balance corresponds to the recent 23.3 million tonne audited increase of its mineral resource estimates the Company announced on January 31. Sigma’s 2023 and 2024 drill campaigns have focused on building resource density along known and preexisting strikes, which will continue to deliver tonnage to our models with limited exploration risk.”

 

 

 

Ana Cabral Co-Chairperson and CEO stated, “This significant increase in mineral Reserves demonstrates our commitment to continuously invest in Brazil to unlock the full economic potential of our mineral concessions. This includes our commitment to build in the country, in the same region where the lithium is mined, a second state-of the-art large scale lithium processing green Industrial plant. We believe Brazil is poised to become one of the global leaders in Lithium production as a result of its optimum conditions for integrated lithium industrial processing and mining: legal certainty in a consolidated mining code, rule of law, straightforward permitting processes, tropical climate, green and affordable renewable energy and power lines infrastructure.”
