Prudent Performance Persists, Preserving Poise & Probity

Barragem Maravilhas III, nestled in Nova Lima’s mining corridor, maintained its stable condition through June 2025, as confirmed by the latest Geotechnical Performance Assessment Report. Prepared by an independent Engineer of Record, the report concluded the dam’s structural integrity remains intact, instruments work within parameters, & safety factors comfortably surpass legal requirements, ensuring peace of mind for nearby residents.

Diligent Developments Drive Downstream Dam Fortification

Construction works on the dam’s second stage pressed ahead, featuring compacted downstream embankment fills & strategic excavations on the flanks. These reinforcements, part of a broader preventive framework, bolster the dam against extreme weather & seismic stress. They show a clear vision: blending engineering expertise with environmental stewardship to extend operational resilience.

Scrupulous Surveillance Safeguards Structural Soundness

Complementing physical upgrades, Maravilhas III benefits from 24/7 surveillance by the Geotechnical Monitoring Center. This facility tracks live data, including movement, pore pressure & strain, ensuring even subtle anomalies prompt swift technical review. This continuous vigilance fortifies trust between operator & the community, reducing risk & fostering early intervention capability.

Affirmative Assessment Anchors Assurance & Accountability

June’s report reaffirmed a positive Declaration of Stability Condition, required by Brazilian regulation to confirm no imminent risk. Importantly, there are no active alerts or emergency statuses. Such clear compliance reflects dedication not only to meeting standards but to openly communicating them, building transparent rapport with Nova Lima & Belo Horizonte’s population.

Community Communication Cultivates Confidence & Continuity

Beyond engineering, the operator prioritises transparent reporting to local stakeholders. Monthly publications in accessible language demystify complex geotechnical terms, making safety data understandable. This openness, paired with real-time monitoring, bridges the gap between technical experts & residents, enhancing credibility & reinforcing community trust.

Sustainable Stewardship Spurs Strategic Strengthening

Maravilhas III’s approach illustrates a broader trend in mining: preventive strengthening rather than reactive repairs. By focusing on high-quality construction materials, data-driven designs & early issue detection, operators align safety priorities with sustainability goals. It is a shift from short-term fixes to long-term resilience in tailings management.

Resilient Resources Reinvent Regional Responsibility

With proactive reinforcement & transparent governance, Maravilhas III stands as a model of responsible mining infrastructure. The commitment to sustainable development, robust engineering & open dialogue ensures that economic growth proceeds hand in hand with environmental responsibility & social reassurance.

Key Takeaways:

• Barragem Maravilhas III maintained a positive stability declaration & stable performance through June 2025

• Reinforcement works progressed, adding downstream embankments & flank excavations

• 24/7 monitoring & open reporting strengthen public confidence & long-term resilience
