Sigma Lithium Achieves Sustainability Excellence While Upgrading Mining Operations

Sigma Lithium Acknowledged for Sustainability

Sigma Lithium Corporation (TSXV/NASDAQ: SGML, BVMF: S2GM34) has made headlines recently after being included as a case study in the influential report titled "Climate and Nature Solutions in Brazil." This notable recognition was granted by Instituto Itausa and Instituto Arapyau, organizations that are pivotal in promoting sustainable development initiatives in Brazil.

Recognition for Sustainability Excellence

The report heralded Sigma Lithium as a leader in sustainability, describing its operations as a "global reference in green lithium." Notably, the company employs 100% renewable energy, achieves 90% water recirculation, and avoids tailings dams, all while utilizing dry processing and gravity separation techniques. These practices embody the "Quintuple Zero" formula, aimed at producing lithium without the usual environmental detriments associated with mining.

The findings also acknowledged Sigma Lithium's innovative adaptation of traditional mining practices, indicating international respect for its superior Environmental, Social, and Governance (ESG) practices. Furthermore, Sigma Lithium is committed to ecological restoration through its reforestation and compensation programs, which enhance social inclusion and biodiversity in the Cerrado regions of Brazil.

Upgrading Mining Operations for Efficiency

In tandem with its recognition, Sigma Lithium is set to upgrade its mining operations, a strategic move intended to bolster its efficiency and competitiveness. Currently, mining operations account for over 66% of the company's plant gate costs. This upgrade will enhance control in ore delivery from mines, ultimately leading to increased production at the Greentech plant while significantly reducing overall costs by approximately 20%.

The decision to execute these upgrades ahead of schedule arises from recent fluctuations in lithium prices, which dropped between April and August 2025. This proactive move not only aims to maintain profitability but also to ensure that the exemplary health and safety standards observed at the industrial Greentech plant are mirrored in the mining operations. The industrial facility has an impressive record of over 735 consecutive days without a Lost Time Injury (LTI), underscoring its commitment to safety and sustainability.

This upgrade, which involves the replacement of mining equipment, is designed to minimize production downtime while maximizing efficiency. Sigma Lithium's strategy also includes modernizing equipment with larger mining trucks, thereby streamlining operations and enhancing safety.

High-Level Global Energy Dialogues

Sigma Lithium's engagement goes beyond operational improvements, reflecting its leadership in the ongoing global energy transition dialogue. The company's representatives participated in various high-profile forums during Climate Week NY, showcasing their commitment to integrating private investment with public policies to forge sustainable mineral supply chains.

The team, including CEO Ana Cabral and VP Daniel Abdo, contributed to discussions to accelerate progress towards Sustainable Development Goal 7, focusing on clean and affordable energy accessibility. They also engaged with global leaders at the United Nations Energy Forum, sharing strategies to refine energy infrastructure, particularly in the context of clean power solutions.

Through these efforts, Sigma Lithium aims to reinforce its reputation as a trusted partner in the sustainable energy landscape, preparing for further engagements at COP30 in Brazil, where it hopes to advance comprehensive solutions for the energy transition.
