Ore reserve mining refers to the practical execution of mining activities in accordance with the sequence, scheduling, and material targets established by the declared ore reserve and associated mine plan. It involves translating the long-term reserve model into operational mine designs, including pit phase or stope sequencing, short- and medium-term production schedules, and equipment allocation, ensuring that the rate and order of extraction align with the economic assumptions used to declare the reserve. Deviations between planned reserve mining and actual operational outcomes are tracked through reconciliation processes that compare predicted versus actual tonnes and grade delivered to the plant, helping identify issues such as excessive dilution, geological model inaccuracies, or unplanned ore loss. In bulk commodities like iron ore and bauxite, reserve mining schedules are often closely tied to contractual delivery commitments requiring consistent product quality over time. In gold mining, reserve mining schedules balance the need to access higher-grade zones early in the mine life to improve project economics against the geotechnical and logistical sequencing constraints of the pit or underground design. Diamond reserve mining must additionally account for bulk sample variability when sequencing blocks of kimberlite ore.
