An ore control system is the integrated combination of technology, sampling protocols, and data management used to implement ore control consistently across a mining operation. Modern systems combine geological databases, grade estimation models, GPS-guided equipment, and real-time sensor data to direct selective mining decisions. Components typically include blast-hole assay databases, three-dimensional grade models updated as new data arrives, dig-limit software that overlays ore-waste boundaries onto operator display screens, and dispatch systems that route trucks to the correct stockpile or crusher based on material grade. Advances such as on-board ore sensors, hyperspectral scanning, and X-ray fluorescence analyzers have improved real-time grade determination, particularly in iron ore and bauxite operations where rapid elemental analysis supports blending decisions. In gold operations, ore control systems increasingly integrate fast assay techniques to shorten the lag between sampling and mining decisions. Diamond operations use specialized ore control systems centered on recovering kimberlite blocks with security and chain-of-custody tracking built in, since the high unit value of diamonds creates unique theft and loss-control requirements not present in bulk commodity mining.
