The rainy season poses significant challenges to mining operations. Haul trucks get stuck in soft ground, haul roads deteriorate, and pit and dump floors become boggy and slippery. Despite these challenges, supervisors and mine leadership must stay a step ahead by initiating wet-weather preparations well in advance, ideally five months before the onset of the rains. Competent sheeting material is not always readily available, which makes understanding pit rock configuration critical. This knowledge enables proactive decisions, such as stockpiling competent material for road and loading bay sheeting when conditions deteriorate. Upon reporting for the night shift, I found the pit loading bay in very poor condition. I immediately assigned a dozer to skim off the soft material, carried out extensive box cutting, and sheeted the area with approximately one metre of competent material. The result was a stable loading bay that allowed operations to run smoothly for the remainder of the 12-hour shift. Although we lost about one and a half hours to restore the conditions, the decision was worthwhile. It eliminated the risk of equipment damage, improved safety, and reduced unnecessary costs associated with burning fuel while dispatching only a few trucks due to poor conditions. These are the types of decisions supervisors must be willing to make. In many cases, it is better to temporarily shut down an operation, fix the problem properly, and resume efficiently rather than operate under unsafe and uneconomical conditions. Equally important, day shift teams must work proactively to prepare work areas for incoming shifts, ensuring conditions are favourable and operations remain sustainable. Mining is a business, effective planning is essential to keep operations safe, efficient, and running.

Desde mi experiencia, este documento suele ser bien conocido por los equipos de geología y planeamiento, pero no siempre llega con la misma profundidad a operaciones mina, procesos o incluso a las gerencias de la compañía. 📉 Y ahí es donde se pierde parte de su valor. Al final, son las decisiones operativas las que transforman el modelo geológico en producción real. Cuando el contenido de estos reportes no se comparte ni se discute entre las áreas operativas, comienzan a aparecer situaciones que muchos reconocen: ✔️ Planes de mina que no reflejan completamente la geometría o continuidad geológica. ✔️ Ciclos de minado presionadas por el corto plazo ✔️ Expectativas de planta que no consideran la variabilidad del yacimiento. La información existe, pero no siempre está en la mesa donde se toman las decisiones. 👉 He visto que las operaciones que logran mejores resultados hacen algo distinto: "mantienen vivo este documento". Lo revisan, lo discuten y lo retroalimentan constantemente con lo que ocurre en campo. Y algo que realmente marca la diferencia es cuando los gerentes de operaciones y los gerentes de unidad conocen bien estos reportes y promueven activamente su uso. Cuando eso sucede, el modelo geológico deja de ser solo un documento técnico y pasa a ser parte de la conversación diaria sobre cómo operar mejor la mina. Ahí empieza a generarse valor real. Porque la conexión entre geología, planeamiento, operaciones y procesos se fortalece, las decisiones se alinean mejor con la realidad del yacimiento y las desviaciones entre lo planificado y lo producido comienzan a reducirse. Al final, un buen reporte de recursos y reservas no solo nos dice cuánto mineral tenemos. Nos ayuda a entender cómo gestionarlo mejor. 📈 Y cuando ese conocimiento circula dentro de la organización, deja de ser un documento técnico y se convierte en una verdadera ventaja operativa y parte del ciclo de mejora continua. 📌 Abro la conversación con la comunidad minera: ¿En sus operaciones el reporte de recursos y reservas se usa activamente para la toma de decisiones, o sigue siendo un documento que se revisa principalmente durante auditorías o actualizaciones del modelo? Será interesante conocer cómo lo están integrando en la gestión diaria de sus operaciones.

Mining looks chaotic from the outside—massive machines, explosions, mountains of rock moving around. Under the hood, though, it follows a surprisingly elegant chain of steps. Think of it as a carefully choreographed industrial dance where geology, engineering, and logistics work together to turn buried rock into valuable minerals. Here’s a simplified look at the mining workflow illustrated in the image: 🔵 Overburden Removal (if existing) • Removing the topsoil and waste rock that sit above the ore body. • This step exposes the valuable mineral layer and prepares the site for extraction. 🟠 Waste Drilling & Blasting • Holes are drilled into the waste rock and explosives are placed. • Controlled blasting breaks the rock into manageable fragments. 🟡 Hauling Waste • Large haul trucks transport the blasted waste material away from the mining zone. 🟤 Dumping Waste • Waste rock is dumped in designated areas while wall monitoring systems ensure pit stability and safety. 🟢 Ore Drilling • Once the ore body is exposed, precision drilling begins to prepare it for extraction. 🔴 Ore Blasting • Controlled blasts fragment the ore so it can be efficiently loaded and transported. 🟣 Hauling Ore • Heavy trucks move the ore from the pit to stockpiles or directly to the processing plant. 🔷 Stockpiling (Grade Control) • Ore is sorted into high-grade, medium-grade, and low-grade stockpiles to optimize processing and recovery. ⚫ Primary Crushing • Crushers (such as jaw or cone crushers) reduce large rocks into smaller pieces suitable for processing. 🟧 Grinding & Processing • The crushed ore enters the mill, where grinding and flotation/separation extract valuable minerals. 🟦 Mineral Concentrate Production • The valuable mineral is separated and collected as concentrate. 🟩 Tailings Management • Waste slurry is sent to a Tailings Storage Facility (TSF) where water is recycled and environmental safety is maintained. Mining is not just about digging rock—it’s a system of geology, engineering, data, and environmental management working together to transform raw earth into usable resources.

En minería, muchas veces los resultados más visibles dependen de acciones que ocurren antes de que empiece la operación principal. Una de ellas es la preparación del banco de perforación, una actividad que puede parecer rutinaria, pero que tiene un impacto directo en la calidad de la voladura, la seguridad en campo y la toma de decisiones operativas. La preparación del banco consiste en acondicionar el área donde trabajará la perforadora para garantizar estabilidad, seguridad y precisión. Esto incluye: • Retiro de rocas de sobre tamaño, permitiendo el tránsito seguro y estable de la perforadora. • Eliminación de rocas sueltas o colgantes en la cresta del talud, reduciendo el riesgo de caída de material. • Construcción de muros de restricción con material de voladura, para evitar el ingreso de personal y equipos no autorizados a zonas de riesgo. Cuando esta actividad se ejecuta correctamente, se logra: ✔ Marcación precisa de la malla de perforación mediante equipos topográficos. ✔ Mejores condiciones de maniobra y circulación para la perforadora. ✔ Terreno seguro y adecuado para el personal durante el carguío de explosivos. ✔ Mejor información para planificaciones de corto y mediano plazo en la explotación de futuros bancos. En operaciones mineras, los detalles operativos previos son los que muchas veces definen el éxito del resultado final. ¿Qué otras acciones operativas “pequeñas” consideran ustedes que generan un gran impacto en seguridad, productividad o calidad dentro de la minería?

In large open-pit mining operations, a question comes up quite often: What matters more for the success of a mine — operations in the field or mine planning? At first glance the answer seems obvious. Production happens in the pit. Excavators load the material, trucks move it, and operations teams manage the equipment and crews that keep production running. But mining rarely works like a fixed industrial project. As the mine advances, geology changes. Stripping conditions vary, water can appear in unexpected places, and ore or coal quality may fluctuate. Because of that, a mine plan is never something that is prepared once and simply followed for years. It constantly evolves as new information comes in. Operations teams focus on making production happen every day. In a large open-pit with hundreds of equipment units — excavators, haul trucks, dozers and support machines — keeping everything running safely and efficiently is already a major task. Dispatching equipment, managing shifts, maintaining productivity and safety… these are all core operational responsibilities. Mine planning and technical services, on the other hand, define the framework in which those operations take place. Planning teams deal with things like pit design, block sequencing, stripping ratios, haul road layouts, production schedules and long-term reserve management. These decisions shape how efficiently the mine will run — and in many cases whether it will remain economically viable over time. Many of the biggest cost drivers in mining actually come from planning decisions. A slightly longer haul distance can increase fuel consumption significantly. Poor sequencing may lead to unnecessary waste movement. Even small design choices can translate into millions of tonnes of additional material over the life of a mine. That’s why a phrase you often hear in mining is: Operations move the material — planning largely determines the economics. In practice, these two functions represent different layers of responsibility. Operations manage the day-to-day execution, while planning teams focus more on long-term optimization of the resource and the cost structure. When these two sides work well together, the result is a much more stable and efficient operation. In many large mining companies such as BHP and Rio Tinto, technical services and mine planning groups play a central role in supporting operational decisions. Geological modeling, production scheduling and cost optimization are all part of the same system. At the end of the day, the real question is probably not which one is more important. A mine performs best when strong operations and strong planning support each other. That balance is what usually separates an average operation from a truly efficient one.
