months. Key contributions include the integration of validation mechanisms for process safety assurance and the demonstration of MDM's role in accelerating progression toward Mining 4.0 and an Integrated Mining Enterprise (IME). Beyond technical outcomes, the initiative fostered cultural shifts toward data-driven collaboration, positioning information as a strategic asset for sustainable performance. Future work should explore scaling MDM to additional Nexa sites, incorporating advanced analytics (e.g., predictive modeling) and evaluating long-term impacts on safety KPIs and resource recovery. This case reinforces that robust data governance is not merely a technological upgrade, but a foundational capability for achieving competitive advantage in complex underground mining environments. 7. ACKNOWLEDGEMENTS The authors would like to express their sincere appreciation to the Nexa Aripuanã team for their dedication and collaborative efforts in successfully implementing the Deswik MDM platform, which were instrumental to the project's outcomes. Special recognition is also extended to the technical support team from Deswik Brasil for their expertise, guidance, and ongoing assistance throughout the deployment process. 8.
