Sigma Lithium Demonstrates Excellence in Environmental Performance Filing Data Collected by External Experts Measuring Low Noise, Low Dust, Low VibrationsJune 2, 2026 6:31 PM
NewsfileHIGHLIGHTSSigma Lithium files one year of external expert environmental data (for the 12 months to May 2026) demonstrating its track record: low levels of dust, vibrations, noise, monitored in four neighbouring communities, as follows:Dust: Sigma Lithium operates 560% better than recommended standards for total suspended particles, 350% better for particle size of below 2.5 micrometers. Noise: 95 measurement campaigns conducted during night and day demonstrated compliance with ABNT standards.Vibrations: The level of vibrations measured in terms of velocity measured in millimeters per second against the frequency measured in Hertz were extremely low, barely registering on the seismograph scale, when set against the ABNT limits.The data series externally collected by experts provides transparent, objective evidence of Sigma Lithium's impeccable environmental track record. The evidence filed directly refutes baseless and unproven claims against the Company made in local Brazilian courts, currently under appeal at the State Courts in Minas Gerais (Tribunal de Justiça de Minas Gerais).São Paulo, Brazil--(Newsfile Corp. - June 2, 2026) - Sigma Lithium Corporation (NASDAQ: SGML) (TSXV: SGML) (BVMF: S2GM34) ("Sigma Lithium" or the "Company"), the largest producer of lithium oxide concentrate in the Americas¹ and dedicated to industrializing socially and environmentally sustainable lithium materials to supply global producers of batteries for energy security, demonstrated the Company's excellence in environmental performance in a filing with one year of data collected by external experts with measurements demonstrating low levels of dust, vibrations and noise generated by its operations.The solid data series externally collected by experts provides transparent, objective evidence of Sigma Lithium's environmental track record and directly refutes baseless and unproven claims against the Company made in local Brazilian courts, currently under appeal within jurisdiction of rule of law at the State Courts in Minas Gerais (Tribunal de Justiça de Minas Gerais). The data points are below the stringent legal limits in Brazil, as well as the established standards of the Brazilian Technical Standards Association ("Associacao Brasileira de Normas Tecnicas" or "ABNT") and Brazil's National Environmental Council ("Conselho Nacional do Meio Ambiente" or "CONAMA").The tables below graphically illustrate the data for Sigma Lithium's environmental performance for airborne particular matter (PM), vibration, and noise over the past year. The data was collected by third-party experts engaged by the Company and demonstrate that Sigma Lithium has consistently performed better than the minimum regulatory legal requirements.Tables 1, 2, and 3 show data with respect to the monitoring of dust. Data is presented for the twelve months to May 2026 showing total suspended particles and particle size below 10 and 2.5 micrometers measured in four locations in the community (C1, C2, C3, and C4). The data shows that the levels of dust generated by Sigma Lithium's operations were 350% to 560% below the CONAMA standard limits established for each category.Table 4 shows the level of vibration measured in the twelve months to May 2026 in terms of velocity measured in millimeters per second against the frequency measured in Hertz. The vibrations (marked by "X" in the chart) are extremely low, when set against the ABNT limits shown in the red line.Table 5 shows the results of noise monitoring in the twelve months to May 2026 that measures compliance with ABTN limits in terms of decibels at four locations. The chart includes a data set for daytime monitoring and another for nighttime monitoring.Anna Hartley, Sigma Lithium's Vice President of Investor Relations and Global Banking said: "Sigma Lithium has chosen to file a full year of environmental monitoring data, independently collected by third party experts, covering dust, noise, and vibration levels. The results underscore our strong environmental performance and leadership in sustainable mining practices. The data provides transparent, objective evidence of our dedication to environmental stewardship and directly refutes claims suggesting otherwise. Sigma Lithium is committed to maintaining the highest standards of social and environmental sustainability. The Company's operations support approximately 19,000 livelihoods, benefiting an estimated 80,000 people in one of Brazil's most economically challenged regions. At Sigma Lithium, we recognize the significance of this impact and embrace this responsibility with the utmost seriousness."Table 1: Sigma Lithium – LOW DUST –Total Suspended Particles (micrometers)Sigma Lithium operates 560% better than recommended standards for total suspended particles, 350% better for particle size of below 10 and 2.5 micrometers.

A10 Global Fund, L.P. Continues to Raise Its Position in Sigma Lithium CorporationMay 29, 2026 11:17 AM
NewsfileSão Paulo, Brazil--(Newsfile Corp. - May 29, 2026) - The A10 Global Fund, L.P. ("A10 Global"), managed by A10 Invest Ltda. ("A10 Invest"), which pursues an investment mandate focused on publicly traded global equities of companies positioned to benefit from macroeconomic trends driving accelerated growth in worldwide demand for critical minerals, announces that it has recently added to its position in common shares of Sigma Lithium Corporation (NASDAQ: SGML) (TSXV: SGML) (BVMF: S2GM34) ("Sigma Lithium" or the "Company"). A10 Global's aggregate purchases during any rolling twelve-month period remained below 5% of Sigma Lithium's issued and outstanding common shares.INVESTMENT RATIONALE AND MARKET CONTEXTA10 Global invests in publicly listed equities globally. Since inception in June 2025, the fund has delivered an annualized return of 177% with an annualized Sharpe ratio of 1.94, representing a balanced management of risk and returns.The fundamental rationale for A10 Global's investment in Sigma Lithium is a conviction in the Company's ability to deliver strong operational performance, as evidenced by its most recent quarterly results. Sigma Lithium's pioneering clean-tech industrial capabilities enable the Company to produce lithium concentrate at costs lower than those of African producers, while upholding the high operational standards typically associated with Australian and Canadian producers. Sigma Lithium's resilient role in the global lithium supply chain for both Asian and Western large downstream clients throughout cycles, has positioned the Company as a significant beneficiary of rising worldwide demand for battery materials and the resulting current favorable lithium pricing environment. The investment case for A10 Invest results from a combination of macroeconomic and microeconomic elements.Macroeconomic elements, learned during our most recent field trip to Asia:An acceleration in the global electrification of mobility driven by recent spikes in fuel prices has led to a stronger consumer adoption of electric vehicles in the EU and a faster implementation of electrification policies in China, particularly for trucks and barges. In parallel, the rapid expansion of the global defense industry's use of low-cost technologies such as drones - mid increasing geopolitical instability in a multipolar world - could further drive lithium demand for mobile applications.A rapid deployment of artificial intelligence is driving significant growth in computing power, which, in turn, is generating concomitant growth in the demand for energy storage systems to power data centers across the United States and in China. The belief that global events with outlying probabilities have been driving lithium demand in recent months has been an overlooked element in the lithium market, and there is also a considerable lag in gauging demand through battery export data or lithium import statistics: a timing mismatch between when lithium first appears in the supply chain and where analyst models typically measure lithium demand.Most models are anchored on utilization data points such as BSS installations, EV sales, and other end use deployments, because of lack of reliable data regarding these lags, when upstream demand actually occurs.Once monthly lithium upstream production is compared with battery cell production (moving average accounts for seasonality), there is a lag, which we believe could be as large as one year. In a rapidly growing market (by over 20% growth YoY), this means that producers are effectively supplying into a market that is significantly larger than the one visible in the utilization data points of current models. Therefore, lithium miners are not supplying 2026 end user demand but 2027 end user demand. Based on current "data points", this is significantly larger, especially when considering recent "outlier" global events, such as current oil supply disruptions, driving a shift in planning for energy security.Microeconomic elements:Sigma Lithium substantially upgraded and restructured its mining operations, expanding its mine hauling fleet by an average of 40% and transitioning from relying on a single mining contractor to having an integrated team of in-house mining specialists and mine automation professionals, supported by independent contractors providing blasting, drilling, equipment, and personnel services.The successful implementation of this upgrade was demonstrated in the first quarter of 2026, when Sigma Lithium announced that the Company successfully ramped up production and remains on track to meet its twelve-month production guidance of 240,000 tonnes of lithium oxide concentrate. Sigma Lithium demonstrated how the Company's results and working capital are highly correlated to both lithium prices (with increased revenues translating into strong margins) as well as lithium demand (with client working capital supporting Sigma Lithium in supplying into the demand time lag for 2027, as outlined above in our macroeconomic case). This unique combination led the Company to achieve the best published profitability in its history in the first quarter of 2026: a net margin of 26% (unadjusted), an EBITDA margin of 39% (unadjusted), and a gross margin of 61%.Sigma Lithium's strong cash flow generation enabled the Company in the first quarter of 2026 to continue a deleveraging trajectory of two years, preparing the balance sheet to absorb new long term and lower cost debt for expansions.Total debt fell by 21% in one year and by 33% in two years.Short-term bank trade debt dropped by more than 75% in one year.The Company disclosed a cash position of US$28 million as of May 15, 2026, which was the highest since year end 2024.Sigma Lithium has a growing production profile: by yearend 2027 the Company is targeting the completion of both its Phase 2 and Phase 3 expansions, which together are expected to increase nominal annual production capacity from 270,000 tonnes to 770,000 tonnes of lithium oxide concentrate. This expansion plan is supported by a constructive lithium pricing environment and Brazil's relatively low capital intensity.Sigma Lithium has a market capitalization of US$1.8 billion and net debt of US$130 million (as of the end of the first quarter of 2026). At approximately current lithium prices, the Company has provided guidance for cash flow of US$1.1 billion once operating at full production capacity following Phase 2 and 3 expansions, suggesting an attractive valuation.The above implies a valuation mismatch of Sigma Lithium compared with the Company's Canadian and Australian peers. This mismatch is heightened by the fact that, despite being a Canadian Company listed in Nasdaq, there has been frequent spikes in short term volatility of Sigma Lithium's share price. In our view, this has been partly generated by a lack of confidence or knowledge of the Company's investor base about Brazil, the emerging market where Sigma Lithium's operations are located. This volatility has often been heightened by the wide dissemination of wrongful and false information about the Company, leading to attractive entry and re-entry points for a fund with monthly liquidity, such as A10 Global.ABOUT A10 GLOBAL FUND, L.P.The A10 Global Fund, L.P. ("A10 Global"), was launched in 2025 by A10 Invest and it is managed by Sigma Lithium's Co-Chair, Marcelo Paiva. A10 Global pursues an investment mandate focused on publicly traded global equities of companies positioned to benefit from macroeconomic trends driving accelerated growth in worldwide demand for critical minerals. A10 Global focuses on market asymmetries created by shifts in macroeconomic variables, which often result in historically high volatility and distortions in the equity valuations of companies operating in emerging markets and new energy industries, such as critical minerals. These dislocations can create compelling value investment opportunities. A10 Global prioritizes companies that are already in production and demonstrate strong operational efficiency, generating above-average margins relative to their industry peers.A10 Global is a Cayman Islands exempted limited partnership managed by A10 Invest Ltda., a Brazilian investment manager registered with Brazil's Comissão de Valores Mobiliários (CVM). A10 Global provides investors with monthly liquidity. A10 Global is a distinct investment vehicle from the Venture Capital fund A10 Investimentos Fundo de Investimento Financeiro em Ações ("Fundo A10 Investimentos"). The two funds have no common investors, operate under different jurisdictions, have different fiduciary liquidity mandates, and are managed by different asset management firms. The only element the funds have in common is their lead Portfolio Manager, Marcelo Paiva, Co-Chair of Sigma Lithium. Fundo A10 Investimentos is a long-term, patient-capital investor established to invest in the industrialization of critical minerals, while serving as a catalyst for economic development and shared prosperity in the communities in which it operates. Fundo A10 Investimentos is managed by A10 Investimentos Ltda. and was the Series A investor in Sigma Lithium shares in 2017 and subsequently participated in Sigma Lithium's IPO at the TSX Venture Exchange in 2018. Fundo A10 Investimentos' only secondary sale of the Company's shares was US$10 million worth of shares sold in a private placement in December 2021 in connection with an increase in the position of a large global fund manager. Fundo A10 Investimentos subsequently reinvested most of the proceeds by acquiring shares of the Company in the market. Other than that, Fundo A10 Investimentos only sold shares in the market to cover its administrative expenses. REGULATORY AND DISCLOSURE FRAMEWORKSubject to applicable legal and regulatory requirements, A10 Global may purchase and sell Sigma Lithium common shares in the open market in the ordinary course of its investment activities and, at times, to provide monthly liquidity to investors. All transactions are executed at prevailing market prices in the stock exchanges and, in aggregate, have not resulted in A10 Global's purchases exceeding 5% of the Company's issued and outstanding common shares during any rolling 12-month period, in accordance with the applicable exemption under Canadian securities laws. All trading activities conducted by A10 Global are carried out in strict compliance with Sigma Lithium's Timely Disclosure, Confidentiality and Insider Trading Policy ("Trading Policy"), given that the fund's Portfolio Manager is also the Co-Chair of the Company and the Portfolio Manager of Fundo A10 Investimentos.Acquisitions and disposals of Sigma Lithium common shares by A10 Global are reported through the System for Electronic Disclosure by Insiders (SEDI) in Canada. While reporting is required within five days of each transaction, A10 Global has a policy of reporting as soon as transactions are closed. As A10 Global's position represents less than 10% of Sigma Lithium's outstanding common shares, SEDI filings appear under the name of the registered portfolio manager at A10 Invest responsible for A10 Global, who is Marcelo Paiva. All trading activity is conducted in compliance with Canadian securities laws.This communication is provided for informational and marketing purposes only and does not constitute investment, financial, legal, tax, or other professional advice.

Sigma Lithium Filing Legal Appeal Against Unwarranted Decision by a Local Judge; "Fake News" Campaign Coincides with Record EarningsMay 18, 2026 4:40 PM
NewsfileSão Paulo, Brazil--(Newsfile Corp. - May 18, 2026) - Sigma Lithium Corporation (NASDAQ: SGML) (TSXV: SGML) (BVMF: S2GM34) ("Sigma Lithium" or the "Company"), the largest producer of lithium oxide concentrate in the Americas¹ and dedicated to industrializing socially and environmentally sustainable lithium materials to supply global producers of batteries for energy security, announces that the Company is filing a legal appeal against a decision issued on Sunday, May 17, by a local judge from a local court in Aracuai, Vale do Jequitinhonha.The local decision included the potential for a legal collateral of US$10 million for the local court. The Company emphasizes this amount would be due only in the event the charges result in a final negative ruling, after the full due legal process is completed in Brazil, including the rights to appeal in the appropriate state and federal courts, including the Supreme Tribunal of Justice (STJ) and Supreme Court of Brazil. The other elements in the ruling are also not expected to be enforced until the completion of due legal process. Legal jurisprudence for similar cases indicates a timeline of multiple years until this happens. As such, no payments are due or required.Sigma Lithium believes the decision is unwarranted and in dissonance with Brazil's strong rule of law: due process was not followed. A significant amount of legal evidence was filed by the Company with the court. The surprising ruling followed a visit by legal authorities to Sigma Lithium's operations, where the Company's conformity with all Brazilian environmental rules was verified, including:Absence of tailing dams and 100% dry stacking of tailings.100% reuse of water by the Greentech Processing Plant, for which the verification included a visit to the Company's inbound sewage treatment plant that removes fecal residues from the water utilized.Bio-regeneration of the Company's rock piles, visually evidenced by growing vegetation.Low levels of noise (even at the mine pit). Low levels of dust, resulting from water trucks running full time at the mining operations conducting site wetting of mining pits and piles.PUBLIC HEARING The visit by the legal authorities occurred on the same day of a public hearing held for the local community, where more than 200 people from Sigma Lithium's neighboring communities attended to demonstrate their support for the approximately 19,000 jobs generated by the Company in the region, ushering in significant shared prosperity in Vale do Jequitinhonha. The overwhelming community support for Sigma Lithium had already been demonstrated in a previous public hearing for the issuance of the Company's environmental license, when over 2,000 people attended and 91% of the depositions heard were favorable to Sigma Lithium's operations and expansion plans. ANOTHER "FAKE NEWS" CAMPAIGN COINCIDES WITH RECORD EARNINGS Prior even to the official issuance of the legal decision yet another negative online "fake news" media campaign was launched against the Company, disseminating false, inaccurate, and misleading information, including videos and photos from the operations of other companies claiming to show Sigma Lithium's operations. More importantly, the campaign was launched on a Sunday prior to the official issuance of the legal decision and just after Sigma Lithium posted record earnings on Friday (for 1Q26).The timing of this negative "fake news" media campaign against the Company, just after a positive announcement or event and leading to substantial stock volatility (the share price fell by 15% today), fits a pattern first reported by the Company on January 23rd, 2026. Sigma Lithium remains in close contact with the appropriate authorities regarding the issue, including FINRA (US Securities and Exchange Commission).ABOUT SIGMA LITHIUMSigma Lithium Corporation (NASDAQ: SGML) (TSXV: SGML) (BVMF: S2GM34) ("Sigma Lithium" or "the Company") is the largest producer of lithium oxide concentrate in the Americas¹ and dedicated to industrializing socially and environmentally sustainable lithium materials to supply global producers of batteries for energy security.The Company runs one of the world's largest lithium production sites-the fifth-largest industrial-mineral complex for lithium oxide concentrate-at its Grota do Cirilo operation in Brazil.

Sigma Lithium Resumes Sales of High-Grade Premium Lithium Oxide; Closes Inaugural Sale at Plant of 400,000t of High-Purity Low Grade Fines Expecting a US$20 Million ProfitMarch 20, 2026 9:00 AM
NewsfileHIGHLIGHTS Sigma Lithium is pleased to announce the resumption of sales of high-grade premium lithium oxide concentrate in 1Q26, achieving industrial production cadence.In 1Q26, the Company is expected to generate gross revenues equivalent to the sale of approximately 28,000 tonnes of high purity premium lithium oxide concentrate at a grade-adjusted price of US$1,712 per tonne.This achievement is a result of industrially beneficiating its dry-stacked tailings and its inventory of raw materials into both high-purity premium lithium oxide fines and high-purity lithium oxide. Sigma Lithium also announces that it has executed its inaugural sale of 400,000 tonnes of high- purity lithium fines for delivery at the plant (ex-works EXW) with an expected profit generated of approximately US$20 million and at a binding fixed price for delivery of US$50/t.The Company now has a remaining inventory of high-purity lithium fines of 300,000 tonnes at the plant, which is expected to generate at least an additional US$15 million of profit under current robust market conditions.São Paulo, Brazil--(Newsfile Corp. - March 20, 2026) - Sigma Lithium Corporation (NASDAQ: SGML) (TSXV: SGML) (BVMF: S2GM34) ("Sigma Lithium" or the "Company"), the largest producer of lithium oxide concentrate in the Americas¹ and dedicated to industrializing socially and environmentally sustainable lithium materials to supply global producers of batteries for energy security, announces that it has resumed sales of high-grade premium lithium oxide in 1Q26, achieving industrial production cadence.In the 1Q26, the Company expects to generate gross revenues equivalent to the sale of approximately 28,000 tonnes of high-purity premium lithium oxide at a grade-adjusted price of approximately US$1,712 per tonne. This performance reflects Sigma Lithium's ability of industrially beneficiating its dry-stacked tailings of fines, as well an existing inventory of raw materials into both premium high-grade lithium oxide and high-purity lithium fines.The Company has also executed its inaugural sale of 400,000 tonnes of high-purity lithium fines at the plant gate to be delivered on an ex-works EXW basis at a binding fixed price of US$50 per tonne. This transaction is expected to generate approximately US$20 million in profit. Following this sale, Sigma Lithium retains an inventory of approximately 300,000 tonnes of high-purity lithium fines at its plant, which is expected to generate at least an additional US$15 million in profit considering the robust conditions for the lithium market expected to prevail during the next few months. The commercialization of low-grade lithium fines by Sigma Lithium demonstrates a considerable "sustainability reward and green premium" to its shareholders. Ana Cabral, Co-Chairperson of Sigma Lithium, said: "The resumption of sales of high-grade premium lithium oxide is in accordance with the outlook we highlighted at our investor presentations this year. By recovering, reprocessing and thus, upgrading, through our proprietary Greentech technology, the previously untapped lithium materials idling at our dry stacked piles, Sigma Lithium delivered a direct financial return on its investment in the clean technology developed for its Greentech Industrial Plant's dry stacking processing module and reprocessing lithium circuits, while creating a permanent new business unit that increases the volume of high-purity lithium materials delivered to our customers, enhancing the diversification of our product portfolio.Sigma Lithium's VP of Business Development Marina Bernardini said: "Our inaugural sales of high-purity lithium fines, delivered at the plant on an ex works basis, confirms the profitability of these sales and highlights the potential for future cash flow to be generated from the remaining inventories of high-purity fines currently at the plant. They also further reinforce the sustainability reward for shareholders that we have demonstrated through successive profitable sales of these products."(1) USGS.ABOUT SIGMA LITHIUMSigma Lithium Corporation (NASDAQ: SGML) (TSXV: SGML) (BVMF: S2GM34), ("Sigma Lithium" or "the Company") is the largest producer of lithium oxide concentrate in the Americas¹ and dedicated to industrializing socially and environmentally sustainable lithium materials to supply global producers of batteries for energy security.The Company operates one of the world's largest lithium production sites-the fifth-largest industrial-mineral complex for lithium oxide concentrate-at its Grota do Cirilo operation in Brazil.

Double Bottom Breakdown on 17 Feb 2026. BLTA

Sigma Lithium Announces Additional Sale of 150,000t plus 350,000t Optional of High Purity Lithium Fines; Production-Backed Revolver of US$96 MillionFebruary 13, 2026 6:00 AM
NewsfileHIGHLIGHTS The Company announces the sale of 150,000 tonnes of high purity lithium fines at US$140/t upon warehouse delivery at the port of Vitoria. The agreement includes an option to sell an additional 350,000 tonnes at market prices.Sigma Lithium is pleased to report that the resumption of production cadence initiates client payments to the Company under the working capital revolver (of US$96 million) backed by 70,500 tonnes of high-grade lithium oxide concentrate to be supplied in 2026.São Paulo, Brazil--(Newsfile Corp. - February 13, 2026) - Sigma Lithium Corporation  (TSXV: SGML) (NASDAQ: SGML) (BVMF: S2GM34) ("Sigma Lithium" or "the Company"), a leading global lithium producer dedicated to powering the next generation of electric batteries with socially and environmentally sustainable lithium concentrate, announces the sale of 150,000 tonnes of high purity lithium fines with 1% of lithium oxide content ("Low Grade Product") at a net final price of US$140/t. The same agreement gives the buyer an option to purchase an additional 350,000 tonnes of the Low Grade Product at market prices upon warehouse delivery at the port of Vitoria. The volume optionality ensures the flexibility to respond to robust market conditions for the Low Grade Product and customer requirements across the Company's portfolio. The commercial success of Sigma Lithium's Low Grade Product can potentially generate the equivalent proceeds of sales of 70,000 tonnes of Sigma Lithium's high-grade lithium oxide concentrate ("High Grade Lithium Concentrate").The sale of the Low Grade Product is the "sustainability reward" for the shareholders of the Company: the successful commercialization is made possible by the quality of the Low Grade Product, which is industrialized using the innovative lithium dense media separation technology of Sigma Lithium's Greentech Plant that preserves the chemical integrity of the lithium crystal structure. As a result of the superior quality of the Low Grade Product, Sigma Lithium's clients achieved up to 60% recovery in re-processing, obtaining lithium concentrate with over 4% lithium oxide content (priced at approximately US$1,370/t currently on average by Shanghai Metals Market). PRODUCTION-BACKED REVOLVERThe resumption of production cadence of the High Grade Lithium Concentrate triggers the commencement of pre-payments under the revolver facility of US$96 million, strengthening Sigma Lithium's near-term liquidity. The unsecured binding agreement signed with a leading company in the battery materials supply chain, provides for the supply of 70,500 tonnes of High Grade Lithium Concentrate by Sigma Lithium during 2026. Under the terms, each prepayment's fixed installment of US$8 million occurs 30 days prior to production and delivery to the Port of Vitoria of an agreed upon quantity. The first prepayment was disbursed, as previously announced, on January 13th. . Each prepayment carries an interest of SOFR +1% for 30 days until final sale upon delivery to the Port of Vitoria.The pricing of each sale is determined to match the prevailing spot market price for High Grade Lithium Concentrate, as per the major indexes, preserving full exposure to price upside and demonstrating a disciplined sales approach as lithium market fundamentals continue to improve. Sigma Lithium's VP of Commercial Catarina Noci said: "This production-backed revolving agreement reflects our client's confidence in Sigma Lithium's ability to deliver consistent High Grade Lithium Concentrate volumes at scale. It builds on a relationship that has developed steadily over time and underscores our role in the lithium supply chain. It follows more than a year of commercial collaboration through our trading partners, during which we have supplied High Grade Lithium Concentrate to support the client's businesses. It speaks to the reliability and quality of our product, as well as to the strength of the partnership we have established.Sigma Lithium's VP of Business Development Marina Bernardini said: "Our sequential sales of the Low Grade Product show how this material can generate recurring value, demonstrating its marketability. Continuous demand for the Low Grade Product has supported the creation of an additional revenue stream for the Company. This opportunity stems from both our large existing inventory of Low Grade Product available for reprocessing and the ongoing annual generation of approximately 300,000 tonnes of this material through our Greentech Plant's dry stacking technology. Our sustainability-centered relationships are mutually beneficial, as our clients generate additional value by concentrating our Low Grade Product into higher grade lithium material".

Miners Win as China's Export Ban Triggers 54-Nation Pact Reshaping Critical MineralsFebruary 6, 2026 1:00 PM
PR Newswire (Canada)

Issued on behalf of GoldHaven Resource Corp. VANCOUVER, BC, Feb. 6, 2026 /CNW/ -- Equity Insider News Commentary — The global supply map just broke. China restricted critical tungsten exports to Japan in January[1], causing the United States to counter by rallying 54 nations and launching $30 billion in strategic financing[2]. This geopolitical chess match is rapidly de-risking domestic production. It position GoldHaven Resources Corp. (CSE: GOH) (OTCQB: GHVNF), Sigma Lithium (NASDAQ: SGML) (TSXV: SGML) , Berkshire Hathaway (NYSE: BRK.A) (NYSE: BRK.B), Rio Tinto (NYSE: RIO), and Talon Metals (TSX: TLO) (OTCID: TLOFD) at the forefront of a massive capital rotation.This is a structural pivot, not a temporary blip. Nearly 75% of business leaders are prioritizing resilience over cost as trade barriers rise[3]. To cement this transition, VP JD Vance recently announced price floors and binding alliances with the EU and Mexico to end single-source reliance[4]. With sovereign capital and preferential trade zones now backing the sector, these companies are becoming essential pillars of the new industrial architecture.GoldHaven Resources (CSE: GOH) (OTCQB: GHVNF) has confirmed anomalous tungsten mineralization at its Magno Property in northwestern British Columbia. The company's 2025 surface exploration program identified a previously undocumented tungsten zone at the Vines Lake showing, where assays returned up to 6,550 parts per million tungsten. These results validate historical tungsten data at the Kuhn and Dead Goat showings while expanding the known footprint across multiple structurally controlled skarn zones spanning approximately 1.3 kilometers of strike length."These results represent a meaningful step forward in defining Magno as a large, zoned, intrusion-related mineral system," said Robert Birmingham, President and CEO of GoldHaven. "The confirmation of high-grade silver-lead-zinc mineralization, extensive tungsten, elevated copper within intrusive rocks, and strong bismuth-tellurium pathfinder anomalies reinforces our interpretation of a porphyry-driven system at depth. The emerging geological and metal zonation patterns share important similarities with Coeur Mining's Silvertip district, while Magno's broader critical-metal footprint highlights the potential for a multi-commodity discovery with district-scale upside."The tungsten discovery comes at a strategically important time for Western economies. China implemented strict export controls on tungsten throughout 2025, and the country controls over 80% of global tungsten supply. The metal possesses the highest melting point of any element, making it essential for cutting tools, defense applications including ammunition and armor, semiconductor manufacturing, and energy infrastructure. These export restrictions have elevated tungsten to critical mineral status across North America and Europe.The 2025 program at Magno successfully verified historical showings while discovering tungsten at Vines Lake where previous sampling had not documented the metal. Results from 357 samples revealed bonanza silver grades up to 2,370 grams per tonne alongside lead values exceeding 20% and zinc reaching 3.8% at the Magno and D-Zone carbonate replacement occurrences. Forty-five samples returned over 100 grams per tonne silver. The discovery of indium adds another strategic dimension, with values up to 334 parts per million. Indium is used in electronics and renewable energy technologies.GoldHaven has also completed its inaugural diamond drilling program at the Copeçal Gold Project in Brazil. Nine holes totaling 1,085.7 meters tested priority targets and discovered bornite, which suggests potential for a substantial gold-copper system. The company also confirmed high-grade copper mineralization at its Three Guardsmen Project, with surface sampling returning grades up to 15.85% copper.GoldHaven now controls 133,186.16 hectares across proven mining jurisdictions with multiple projects advancing simultaneously and assay results pending from Copeçal. All projects are supported by a comprehensive 43-101 Technical Report.CONTINUED… Read this and more news for GoldHaven Resources at: https://equity-insider.com/2025/10/02/the-goldhaven-story-two-continents-one-strategy-systematic-historic-gold-district-exploration-2/In other industry developments and happenings in the market include:Sigma Lithium (NASDAQ: SGML) (TSXV: SGML) sold an additional 100,000 tonnes of high purity lithium fines at market prices equivalent to an adjusted net final price of $140 per tonne for 1% lithium oxide content. The company reaffirmed that remobilization of contractors and equipment at its Grota do Cirilo mine site is proceeding as planned and expected to conclude in January 2026.Sigma Lithium categorically denied recent media reports incorrectly characterizing an administrative inquiry by Brazil's Ministry of Labor and Employment as an "operational injunction," describing the coverage as part of a coordinated defamatory campaign. The company maintains the administrative inquiry does not constitute material information and does not impact its ability to operate or execute mine remobilization activities that will maintain an estimated 19,000 direct and indirect jobs in the Jequitinhonha Valley.Berkshire Hathaway (NYSE: BRK.A, BRK.B) completed its acquisition of OxyChem from Occidental for $9.7 billion, adding a leading producer of essential chemistry with operations across North America. OxyChem is a top three U.S. manufacturer of polyvinyl chloride, chlor-alkali and chlorinated organic chemicals, and calcium chloride supporting critical applications in water treatment, pharmaceuticals, healthcare, and manufacturing.OxyChem's products play an essential role in everyday life, supporting applications in manufacturing, automotive, personal hygiene, and residential and commercial construction. The company will continue to be managed by Wade Alleman, OxyChem president and CEO.Berkshire Hathaway and its subsidiaries engage in diverse business activities including insurance and reinsurance, utilities and energy, freight rail transportation, manufacturing, retailing and services. The acquisition strengthens Berkshire Hathaway's portfolio of industrial operations with a strategic producer of chemicals essential to modern infrastructure and manufacturing.Rio Tinto (NYSE: RIO) and Aluminum Corporation of China Limited (Chalco) entered into a definitive agreement with Votorantim to acquire, through a joint venture owned 33% by Rio Tinto and 67% by Chalco, Votorantim's 68.596% controlling shareholding in Companhia Brasileira de Alumínio (CBA) for R$10.50 per share. The transaction values Votorantim's shareholding in CBA at approximately $902.6 million, with Rio Tinto's pro-rata amount being $297.8 million."This acquisition, jointly with Chalco, of Votorantim's controlling position in CBA's fully integrated aluminium supply chain in Brazil is aligned with our strategy to deliver value for shareholders by extending our low-carbon, renewable-powered aluminium footprint in rapidly growing markets," said Jérôme Pécresse, Rio Tinto Aluminium & Lithium Chief Executive. "Our partnership with Chalco brings together our combined operational excellence, innovation and unique project execution capabilities, unlocking the potential to create value for the benefit of our shareholders, as well as CBA's employees, customers and local communities."CBA is a vertically integrated low-carbon aluminium business supported by a 1.6 GW portfolio of renewable power generation assets. Rio Tinto International Holdings Limited will hold Rio Tinto's 33% shares in the joint venture, with the transaction subject to regulatory approvals and customary closing conditions.Talon Metals (TSX: TLO) (OTCID: TLOFD) reported an 8.85-meter massive sulphide intercept grading 9.60% nickel, 12.65% copper, and 11.12 g/t gold in drill hole 25TK0563B at its Vault Zone. Step-out drilling confirmed mineralization continuity approximately 79 meters below the Tamarack Resource Area, with drill hole 25TK0567 intercepting 35 meters of mixed massive sulphides starting at 645.26 meters."With the transaction with Lundin Mining now complete, our combined team is positioned to advance our four strategic priorities in parallel working to materially extend the Eagle Mine life, accelerating exploration in Michigan and Minnesota," said Darby Stacey, CEO of Talon Metals. "Our methodical approach of focusing on Borehole Electromagnetic anomalies coupled with precision drilling has continued to deliver success within the Vault Zone."The company's three in-house drill rigs continue actively drilling the Vault Zone with mineralization remaining open in all directions. Talon Metals operates the Eagle Mine in Michigan, currently the only primary nickel mine operating in the United States, positioning the company to supply critical minerals for domestic battery production.Article Sources:

Sigma Lithium Highlights the Issuance of an Official Technical Statement Declaring the Safety of Its Waste Piles by Brazil's National Mining AgencyFebruary 4, 2026 6:00 AM
NewsfileHIGHLIGHTS Brazil's mining regulator, Agencia Nacional de Mineracao ("ANM or Mining Regulator") issued an official technical statement about Sigma Lithium's waste piles, directly attesting their safety. The Mining Regulator unequivocally stated that it did not encounter any legal prerequisites for the adoption of precautionary measures of closure of Sigma Lithium's operations or waste piles.ANM is the regulatory authority with powers over mining activities in Brazil. It is the body of the Brazilian Government with a team that is equipped with the capabilities to execute technical mining audits. Sigma Lithium restates that the administrative enquiry opened by the Brazilian Ministry of Labor and Employment during a regular inspection regarding health and safety in December 2025 has no material effect on the Company's capacity to continue to execute its mining activities, which are in the process of being ramped up to mine plan capacity.During the abovementioned inspection, the Brazilian Ministry of Labor and Employment had the opportunity of verifying the Sigma Lithium's impeccable safety record, with over 2 years without labor accidents with lost time.The scale of the Company's environmentally licensed areas for its Mine 1 operations (received in 2019 and 2022) endows it with several options for the location of piles of waste rock removed from its mining pits. São Paulo, Brazil--(Newsfile Corp. - February 4, 2026) - Sigma Lithium Corporation (TSXV: SGML) (NASDAQ: SGML) (BVMF: S2GM34) ("Sigma Lithium" or "the Company"), a leading global lithium producer dedicated to powering the next generation of electric batteries with socially and environmentally sustainable lithium concentrate, 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 Mining Regulator unequivocally confirmed in the Statement the absence of evidence of serious technical risk and that it did not encounter any legal prerequisites to adopt precautionary measures of closure.The Statement, issued on February 2, mentioned that: "The inspections, which were carried out through drone overflight and visual assessment by walking, did not identify geotechnical anomalies indicative of an imminent risk of global instability in the inspected structures." The Statement continued "considering the absence of evidence of serious and imminent risk, it is concluded that, at present, the legal prerequisites for adopting precautionary measures of closure have not been met." The Statement was issued following the abovementioned inspections of Sigma Lithium's mining operations by the Mining Regulator 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.ABOUT SIGMA LITHIUMSigma Lithium Corporation (NASDAQ: SGML) (TSXV: SGML) (BVMF: S2GM34) ("Sigma Lithium" or "the Company"), is a leading global lithium producer dedicated to powering the next generation of electric batteries with socially and environmentally sustainable lithium oxide concentrate.The Company operates one of the world's largest lithium production sites-the fifth-largest industrial-mineral complex for lithium oxide concentrate-at its Grota do Cirilo operation in Brazil. Sigma Lithium is at the forefront of environmental and social sustainability in the electric battery materials supply chain, producing Quintuple Zero Green Lithium: zero coal power, zero tailings dams, zero utilization of potable water, zero use of hazardous chemicals and zero accidents.Sigma Lithium currently has a nameplate capacity to produce 270,000 tonnes of lithium oxide concentrate on an annualized basis (approximately 38,000-40,000 tonnes of LCE) at its mine and state-of-the-art Greentech Industrial Plant. The Company is now constructing a second plant to double its production capacity.For more information about Sigma Lithium, visit our websiteFOR ADDITIONAL INFORMATION PLEASE CONTACTAnna Hartley, Vice President of Global Banking and Investor Relations

CORRECTION FROM SOURCE: Sigma Lithium Announces the Resumption of Mining Activities at Mine 1, with over 600 People Working on SiteFebruary 2, 2026 12:07 PM
NewsfileHIGHLIGHTS Sigma Lithium announces the resumption of mining activities at its Mine 1 in Vale do Jequitinhonha in Brazil, as scheduled.This step successfully concludes the restructuring of mining operations aimed at increasing safety and operating efficiency, with the Company's technical leadership managing mining activities and planning, while incorporating a larger off-road mining fleet to match the increased production capacity achieved by the Greentech Industrial Plant.The restructuring was financed in part by the commercial success of Sigma Lithium's high-purity low-grade lithium oxide concentrate fines, which can potentially generate equivalent proceeds to those of selling approximately 70,000t of Sigma Lithium's high grade lithium oxide concentrate product.The new mining operational structure is expected to fully support the increase in production scale planned within the next 12 months, with the resumption of construction and subsequent commissioning of the Phase 2 Greentech Industrial Plant.Demonstrating how Sigma Lithium's low costs can enable the generation of robust cash flows under any production scenario for Phase 1, we provided an illustrative annual guidance for cash flow generation utilizing two different historical scenarios for Phase 1's ongoing production (220,000tpy and 270,000tpy) and for Phase 2 (520,000tpy); (see Table 1 below). The Company will provide guidance for the full year 2026 output once production resumption reaches a "steady state" during 1Q26.This press release corrects and replaces the version issued by Sigma Lithium Corporation on February 2, 2026, titled “Sigma Lithium Announces the Resumption of Mining Activities at Mine 1, with over 600 People Working on Site”.São Paulo, Brazil--(Newsfile Corp. - February 2, 2026) - Sigma Lithium Corporation (TSXV: SGML) (NASDAQ: SGML) (BVMF: S2GM34) ("Sigma Lithium" or "the Company"), a leading global lithium producer dedicated to powering the next generation of electric batteries with socially and environmentally sustainable lithium concentrate, announces that it has resumed mining activities at the Company's Mine 1 in Vale do Jequitinhonha in Brazil, as scheduled. The resumption successfully concluded the restructuring of the Sigma Lithium's mining operations that occurred during 4Q25, with the Company's technical leadership directing and managing all mining restructuring activities and planning and leading subcontractors providing equipment, including blasting and drilling services, as well a regional workforce of mining personnel (drivers and machine operators). In addition to increasing safety and operating efficiency, this restructuring had the objective of tripling previous earth moving capabilities through the incorporation of a larger "off road" equipment fleet to match the increased production capacity of the Company's Greentech Industrial Plant while providing the cadence of ore delivery it required.The restructuring was financed in part by the commercial success of Sigma Lithium's high-purity low-grade lithium oxide concentrate fines ("Fines"), produced by the Greentech Industrial Plant (dry stacked). The sale of Fines started generating meaningful gross proceeds. Illustratively, applying the price of US$140/t (last sale) to the inventory available of 950,000t (at year end), this can potentially generate equivalent proceeds to selling approximately 70,000t of Sigma Lithium's high-grade lithium oxide concentrate at US$1,800/t (3 months of the Greentech Industrial Plant's main product output). Additionally, Sigma Lithium was able to benefit from the financial support of its large global clients and financiers, which have continuously been providing contractual collateral and working capital lines against future production (70.5kt, as previously announced), replacing additional third-party capital that would have been required. The new mining operational structure is expected to fully support the increase in production scale planned within the next 12 months, with the resumption of construction and subsequent commissioning of the Phase 2 Greentech Industrial Plant, designed to meet the fast-growing demand for lithium battery materials. The mining restart is being structured according to a staged equipment deployment plan, with third-party equipment deployed on site, followed by leased equipment, in alignment with mine sequencing and site safety protocols. This approach ensures a controlled ramp-up process within 1Q26, resulting in the delivery of gradually increasing volumes of ore to Sigma Lithium's Greentech Industrial Plant, which has continued to operate by processing strategic stockpiles of dry-stacked tailings and previously mined ore (OSP-mixed with higher quantities of host rock).The Company will provide guidance for the full year 2026 output once production resumption reaches a "steady state" during 1Q26, after all equipment is mobilized and mining activities are running at full capacity. The table below illustrates Sigma Lithium's potential cash flow generation utilizing two different historical scenarios for Phase 1 ongoing production and for Phase 2 and demonstrates how the Company's low costs can enable the generation of robust cash flows under various production scenarios for Phase 1 and in different lithium price environments, demonstrating the operational resilience to withstand the volatility of lithium markets.

Substantial revenue growth

Sigma Lithium reported net revenues of $28.5-million (U.S.) for Q3 2025, representing substantial increases of 69 per cent quarter over quarter and 36 per cent year over year. The increases reflected a successful commercialization strategy, which enabled the company to maximize seasonal lithium price variations and lock gains, enabled by the company's provisional pricing strategy. The increase on a quarter-over-quarter basis also reflected better sales volumes, which rose 21 per cent primarily because in the previous quarter, in line with Sigma Lithium's disciplined commercial strategy, the company temporarily withheld product from the market during periods of intense price volatility to preserve pricing power and protect long-term margins.

Mining operations upgraded to match Greentech industrial plant 3.0

Following the upgrade in the Greentech industrial plant last year in November, 2024, it has been recurringly delivering unprecedent recovery levels since January, 2025, with over 70 per cent at plant level. As a result, in 2026, the company plans to reach the full Greentech industrial plant capacity of 300,000 tonnes, already achieved in Q4 2024.

As a result, the company's medium-term mine plan was extensively reviewed throughout the year: Initiatives to assess the upgrade in mining operations currently in execution include the increase in the size of the mining equipment (double the capacity of trucks and excavators) and full digitalization of controls in mining operations, including fleet and diesel. Sigma Lithium took over the mining operations from a previous equipment contractor and plans to be leasing equipment directly from manufacturers, financing this upgrade through offtake agreements in Asia, with low interest rates. The company expects mining operations to resume by the end of November, achieving a full ramp-up by Q1 2026.

Significant improvement in cash position in contrast to peers

As of Sept. 30, 2025, the company's had cash and cash equivalents of $6.1-million (U.S.) in addition to $20-million (U.S.) from trade receivables booked in the quarter totalling $26.1-million (U.S.).

Currently, as of Nov. 13, 2025, Sigma Lithium converted the trade account receivables into $21-million (U.S.) in cash and benefited from an $8-million (U.S.) increase in the value of certain settled trade receivables sold by the end of Q2 2025, totalling $29-million (U.S.) representing a significant improvement in the company's liquidity.

Additionally, the company has the opportunity to monetize its high-purity reprocessed lithium materials (middlings) in the robust lithium market environment during this quarter.

Deleveraged by decreasing trade finance short-term debt

During 2025, Sigma Lithium has substantially deleveraged by reducing its expensive short-term trade finance by 38 per cent to $37-million (U.S.) as of Sept. 30, 2025. Additionally, the company continued to execute this strategy planning to decreasing the trade finance debt by 60 per cent to Nov. 30, 2024.

Brazil Draws a Line on Strategic Minerals 🇧🇷⚒️
https://www.linkedin.com/posts/pieter-borsje-28156185_brazil-draws-a-line-on-strategic-minerals-activity-7360524933493362689-GO9t?utm_source=share&utm_medium=member_desktop&rcm=ACoAACqICfIBDnVCtKiuX6gsoBWZSJ9pAt341yg
President Lula has unveiled a new national policy on strategic minerals, framing it as a matter of national sovereignty.

The core idea: no more exporting raw ore without adding value in Brazil — a bid to avoid the historic trap of selling resources cheap and buying back finished products at a premium.

The timing is striking. A 50% U.S. tariff on Brazilian imports is now in force, tied to political tensions over the Bolsonaro investigation. This puts Brazil’s miners in a tight spot — but also gives Brasília leverage to:
• Pivot trade flows toward new premium buyers.
• Accelerate domestic processing capacity.
• Map and monetize untapped mineral wealth via a new national council on mineral materials.

Brazil’s mineral endowment is vast — from rare earths to battery metals. If Lula’s government can align policy, infrastructure, and investment, the country could become a kingmaker in the global energy transition.

The question is execution. Will Brazil seize the moment, or let it slip?

Yes, Electrovaya Inc. is a lithium-ion battery company.

🔋 Company Overview
Core Business: Electrovaya specializes in lithium-ion battery technology and manufacturing, with a focus on energy storage solutions for industrial vehicles, grid storage, and transportation sectors.

Technology Platform: Their proprietary Infinity Battery Technology uses advanced materials like ceramic composite separators and NMC cathodes to deliver high safety, long cycle life, and robust performance.

Manufacturing Expansion: Electrovaya is building out a major facility in Jamestown, New York, where it will produce lithium-ion cells and battery systems. This expansion is backed by over $80 million in funding, including a $50.8 million loan from the U.S. Export-Import Bank.

Applications: Their batteries are used in mission-critical applications such as airport ground support equipment, electric forklifts, and energy storage systems.

🌍 Strategic Positioning
Electrovaya is one of the few independent lithium-ion battery manufacturers in North America, positioning itself as a key player in the domestic supply chain for clean energy technologies.

The company is also exploring solid-state battery development, which could further enhance its technological edge.

Would you like a breakdown of their competitive advantages or how they compare to other lithium battery players like AMPX or SLDP?

Nice.....They're gonna be around the 4th or 5th largest producer in the world

Brazilian lithium producers plan expansions amid falling prices
Despite falling prices, three Brazilian lithium plants – owned by Sigma Lithium, Companhia Brasileira de Lítio (CBL) and AMG Lithium – are seeking to expand their operations in the coming years, in order to become more competitive in the global market, Fastmarkets heard during the “Lithium Business Brazil” event held July 8-10 in the state of Minas Gerais.
July 16, 2025

https://www.fastmarkets.com/insights/brazilian-lithium-producers-plan-expansions-amid-falling-prices/
“Today we have high fixed costs and low production capacity. We will increase capacity and will maintain our costs. Our biggest cost today is labor and, with this expansion, we will not increase our labor force. There will be very little investment in new people, because everything is automated. We need to grow now and then take advantage of the positive lithium price scenario that for sure will come someday,” he said.

Alvarenga explained that this is a brownfield project: “We will use the entire structure from the current plant. This is the least capital-intensive refinery project in the market, compared to other refinery projects worldwide currently.”

Saved at another place. Need to check on Elva.
