Quality Control Across the Mineral Value Chain

Quality control extends beyond the processing plant and touches every link in the mineral value chain. During exploration and resource definition, rigorous sampling and assaying of drill core provide the data for resource estimation and mine planning. The quality of this early-stage data directly affects the economic viability of a project. In mining operations, grade control sampling guides selective extraction to minimize dilution and maximize mill feed grade. Blending strategies, informed by quality data, ensure that the plant receives consistent feed despite ore body variability.
