Emerson Corporation (NYSE: EMR), a global industrial automation leader, has been selected by South32 to deliver a fully integrated digital automation and remote operations platform for the development of its Hermosa zinc project in Arizona. The strategic engagement was confirmed on November 17, 2025, and includes the deployment of Emerson’s DeltaV control system, software portfolio, and smart field infrastructure across both surface and underground operations. This deal positions Hermosa as one of the first U.S. mining projects to be classified by South32 as a “next generation mine,” and reflects a broader shift within the mining industry toward remote, low-emission operations driven by intelligent control systems.
South32 is developing the Hermosa mine in Santa Cruz County, Arizona, with a view to producing critical minerals such as zinc, lead, and silver in response to rising global demand from clean energy, infrastructure, and defense sectors. According to sector forecasts, consumption of these minerals is expected to increase by 10 to 25 percent by 2035 due to accelerating electrification, battery production, and solar energy growth. The Hermosa site is therefore seen not only as a commercially valuable asset, but also as a critical node in the United States’ domestic supply chain resilience strategy.
How is Emerson’s DeltaV control system transforming critical mineral mining operations?
Through its DeltaV automation platform, Emerson Corporation will provide a digital control backbone for the mine, enabling real-time data collection and centralized monitoring across key systems such as ore processing, power consumption, ventilation, and water management. Emerson’s solution is designed to help South32 achieve higher productivity with reduced energy usage, while also enhancing worker safety by minimizing the need for on-site personnel in high-risk environments.
What role will the Centro remote operations center play in redefining mine management?
A critical part of this transformation is the construction of South32’s Centro remote operations center, which is being built approximately 30 miles from the mine site. Centro is a commercial-style office facility that will host around 200 full-time engineers, analysts, and operators who will manage the mine remotely. The integration of Emerson’s software suite into Centro will facilitate centralized decision-making, asset health monitoring, and predictive maintenance capabilities using advanced analytics. This approach reflects a growing industry preference for remote operations models that decouple mine management from proximity to the physical site.
Why is South32 positioning Hermosa as a next-generation model for digital mining?
The digital integration will include Emerson’s control software, asset performance tools, and smart field devices, all of which will feed live telemetry into a secure operational environment. This design supports automated decision-making, ensures continuous optimization of systems, and enhances the mine’s resilience to external disruptions. The platform’s cybersecurity architecture and failover capabilities will also play a role in maintaining operational continuity for what is expected to be one of South32’s most advanced mining assets.
How will Emerson and Caltrol ensure long-term operational reliability and service delivery?
Emerson’s involvement in the project is being supported on the ground by Caltrol, Emerson’s authorized Impact Partner in the region. Caltrol will provide maintenance services, engineering support, and rapid-response capabilities throughout the commissioning and operational phases of the project. The inclusion of an experienced regional partner is aimed at ensuring consistent standards and minimizing response times for any unplanned events.
What does Emerson’s selection tell us about the shift toward sustainable industrial automation?
Ram Krishnan, Chief Operating Officer of Emerson Corporation, stated that South32’s selection of Emerson for the Hermosa project reflects a clear alignment between sustainability goals and industrial innovation. He described the initiative as a “forward-looking investment” that not only supports economic growth but also contributes to long-term energy security by enhancing the efficiency of critical mineral production.
How does the Hermosa project align with U.S. clean energy and mineral security priorities?
South32, a Perth-headquartered multinational with a global footprint spanning Australia, India, China, Brazil, South Africa, and the United States, has positioned Hermosa as a central pillar in its broader decarbonization and digitization roadmap. As part of its commitment to develop future-facing mining projects, South32 is embedding environmental performance metrics into the mine’s design and operational blueprint from the outset. The company has framed Hermosa as a benchmark project that will inform future development models across its global asset portfolio.
Why are investors closely tracking Emerson’s push into digital-first mining projects?
The broader context for Emerson Corporation is also notable. Over the past several years, Emerson has been rebalancing its industrial portfolio by shifting away from commodity hardware toward software-led industrial solutions. Its automation platforms, including DeltaV and Ovation, are increasingly being used across sectors such as water utilities, power generation, life sciences manufacturing, and now, hard rock mining. The deal with South32 underscores Emerson’s strategy of embedding itself deeper into long-cycle capital projects that generate recurring service and licensing revenue.
What makes remote operations centers like Centro a scalable model for modern mining?
The announcement has also sparked fresh interest in how remote operations centers like Centro are changing the operational fabric of the mining industry. Traditionally, remote operations have been reserved for large-scale iron ore or oil sands projects, often in Australia or Canada. South32’s decision to build such an advanced facility in Arizona signals that the model is becoming viable for mid-scale polymetallic mines, especially in jurisdictions with stable infrastructure and policy support.
How is Centro redefining workforce strategy and site safety in industrial mining?
Centro’s deployment in Arizona also opens a new chapter for U.S.-based digital mining infrastructure. The concept blends commercial office environments with high-performance computing systems, allowing for a new type of talent attraction and retention in the mining workforce. With 200 staff operating from a modern facility rather than remote field camps, South32 is also creating a new narrative for industrial employment in Arizona’s mineral sector.
What are the financial implications for Emerson and what will the market watch next?
While specific financial terms of Emerson’s deal with South32 were not publicly disclosed, industry observers expect the value to be significant based on the scope of automation, the integration depth, and the length of service requirements. Investors are expected to watch for milestones such as commissioning of the Centro center, production ramp-up at Hermosa, and any follow-on contracts that extend Emerson’s involvement into other South32 projects.
Could the Emerson–South32 partnership serve as a model for future critical mineral projects?
The Hermosa engagement comes amid a wider trend of increased collaboration between automation vendors and critical minerals producers. With rising investor pressure on emissions, productivity, and supply chain transparency, mining companies are seeking integrated solutions that can deliver operational excellence while meeting ESG benchmarks. Emerson’s software stack, paired with local service partners like Caltrol, appears to be hitting a sweet spot for these dual imperatives.
For South32, the success of Hermosa could help pave the way for similar deployments in other jurisdictions where it holds zinc, copper, or battery metal interests. The project’s digital-first foundation offers a replicable model that may influence mining project design not only in North America but globally.
As the U.S. ramps up domestic mining initiatives tied to energy transition goals, partnerships like the one between South32 and Emerson could define how quickly and effectively new mineral capacity can be brought online without compromising environmental or operational standards.
