Sigma Lithium Highlights the Issuance of an Official Technical Statement Declaring the Safety of Its Waste Piles by Brazil's National Mining Agency Sigma Lithium Corporation highlights the issuance of a publicly disseminated official technical statement ("Statement") by Brazil's mining industry regulator, Agencia Nacional de Mineracao ("ANM" or "Mining Regulator"), explicitly attesting the safety of Sigma Lithium's waste piles. The Statement was issued following the abovementioned inspections of Sigma Lithium's mining operations by the Mining egulator on January 20. The swift action by the Mining Regulator to conduct the inspections and issue a technical opinion regarding the Company's waste piles underscores the official effort by the Government of Brazil to protect the legal security and certainty for companies with mining activities in the country, underscoring the strong governance of the industry in Brazil. The Statement dispelled false information with respect to the Company's waste piles disseminated illegally in a negative media campaign against Sigma Lithium, which included the falsification of a Brazilian government web domain as well as Brazilian government communications (through phishing, using false domains versus the official ".gov.br"). As stated in a press release issued by Sigma Lithium on January 23, the Company's management does not consider that the ongoing administrative enquiry with respect to certain of the Company's waste piles ("Enquiry") by the Brazilian Ministry of Labor and Employment ("Ministry") has a material effect on Sigma Lithium's capacity to continue to execute its mining activities underway. Therefore, the Company's management considered the Enquiry as not constituting material information when it was initiated last year, and this remains the case. In December 2025, the Ministry conducted a regular safety and health inspection at Sigma Lithium, when it had the opportunity to verify the Company's impeccable safety records, with over 2 years without labor accidents with lost time. Following the visit, the Ministry opened the Enquiry. The issuance of the Statement by the Mining Regulator, which unequivocally confirms the safety of Sigma Lithium's waste piles, subsidizes the interactions of the Company with the Ministry with respect to the Enquiry. Sigma Lithium has maintained continuous dialogue and collaboration with the Ministry, providing all the necessary documents, technical reports, data collection sources and other requested information, demonstrating the full compliance of its operations with applicable rules and regulations. Sigma Lithium believes that the timely involvement of the Mining Regulator supports the Company's clarification to the Ministry that its "waste piles" are, in fact, hard schist rock mined from the pits and are a common feature of most base metals' operations with host mineral rocks and contact zones. These hard rock piles have been routinely confused with "tailings piles" of lithium fines, which are less common in lithium operations globally, as few companies have deployed Sigma Lithium's green technology for dry stacking (not utilizing dams). The Company has been able to sell and generate substantial demand for these dry stacked lithium fines because their lithium crystal particles are kept intact after processing by Sigma Lithium's Greentech Industrial Plant. These sales proceeds are an "environmental bonus" that is being reinvested in the operations of the Company, resulting from its clean Dense Media Separation technology that does not utilize chemical reagents to segregate the lithium crystal particles from its host rock to produce lithium oxide concentrate. The overall disinformation in the marketplace about the Enquiry and Company's "piles" has created significant volatility in Sigma Lithium's share price and, in the Company's opinion, it is very clearly the result of an ongoing well-orchestrated and well-funded defamatory campaign to confuse market participants, including investors, banks, newswires and even renowned expert opinion makers, such as research analysts at Bank of America, a thought-leader global financial institution (that has historically provided strategic advice to Sigma Lithium). The Company is in close contact with the appropriate authorities, including FINRA (US Securities and Exchange Commission), regarding these events. お知らせ • Jan 23
Sigma Lithium Corporation Announces the Sale of an Additional 100,000 Tonnes of High Purity Lithium Fines Sigma Lithium Corporation announced the sale of an additional 100,000 tonnes of high purity lithium fines. Sigma Lithium reiterates that the remobilization of the contractor for equipment and personnel at the site of its mine is proceeding as planned and is expected to conclude in January 2026. The Company vigorously denied as "fake news" the inaccurate recent media reports that incorrectly denominated as an "operational injunction" an administrative process initiated by the Ministry of Labor and Employment. Sigma Lithium also states as categorically incorrect the media reports speculating about the status of the safety of its waste piles because of this administrative process, which does not represent a material event. The Company concluded the sale of 100,000 tonnes of high quality lithium fines stored at the Port of Vitoria at market prices (based on Shanghai Metals Market "SMM" index). The price was equivalent to an adjusted net final price of USD 140/t for 1% of lithium oxide content (currently priced by SMM at USD 195/t for 1.35%). The Company is now constructing a second plant to double its production capacity.
