Gold Fields reviews INDIMIN Coach experience at Cerro Corona mine in Peru
The experience with Gold Fields at the Cerro Corona mine in Peru with INDIMIN Coach technology was among the topics presented at ExpoCobre in Lima held 27-29 April, an event that brought together industry stakeholders to address challenges, solutions, and trends in the mining sector.
During their presentation, both companies shared details of the work carried out at this operation, where the incorporation of technological tools for the effective management of on-site processes has strengthened operational control and supported decision-making at the mine site. This approach is focused on reducing operational variability, improving team coordination, and providing greater visibility into critical processes within the mining cycle.
As part of the case study, results obtained at Cerro Corona were presented, where the implementation of INDIMIN Coach allowed for the recovery of an additional 153,000 t of production over a 90-day period, equivalent to 3.4% above the mining plan, reducing operational losses in key processes such as loading and hauling. For his part, Luis Carlos Sanchez Pastor, Head of Innovation at Gold Fields Peru, commented during the presentation that, as part of their innovation strategy, they are continuously exploring new technologies that can improve the efficiency of their processes. This led to initiatives like INDIMIN Coach, which, after a successful pilot program, was scaled up to an industrial level at Cerro Corona.
INDIMIN Coach is described as the first intelligent digital assistant for personalised productivity, delivering predictive feedback for efficiency, safety, and empowerment in processes and work teams during day-to-day mining operation. It provides a link between operators and supervisors for improvement and specific feedback, plus safe use controls by schedule and zone, as well as productivity and monitoring of personalised performance indicators. Users can download safety, operational, and administrative documents.
It offers online detection of patterns of operational inefficiencies, safety, and equipment care, plus application of artificial intelligence models for prediction of yields or results at the end of the shift. Recommendations, messages and operational alerts provide traceability of actions shift by shift.
The presentation at ExpoCobre Peru also showcased the current state of the operation. Cerro Corona is no longer planning any new blasting and is moving towards its mine closure process, while the remaining stockpile continues to be processed and transported to feed the plant. In this context, the ongoing collaboration between Gold Fields and INDIMIN will focus on supporting this stage, with an emphasis on productivity, safety, ore control during transport, and ensuring a continuous supply to the plant.
During the presentation, Nicolas Rojas, Business Development Manager for Latin America at INDIMIN, discussed the main productivity results achieved and the next steps in controlling the plant’s feed, aimed at improving ore recovery. He also highlighted the contribution of these tools to the safe management of operations in the loading and transport processes.
Alvaro Diaz, General Manager of INDIMIN, noted that this new scenario opens up a different space for the use of technology in mining. “Today, the challenge lies not only in capturing efficiencies in extraction, but also in safeguarding operational continuity in a different phase of the mine, where process control, safety, and plant recovery become especially critical.” The next steps in this collaboration in Peru aim to support the mine closure cycle and then the reprocessing, seeking to optimize ore tracking, improve its continuity to the plant, and contribute to maximising recovery in this final stage of the operation.
