A Mining Operation Plan, often abbreviated MOP, is a comprehensive technical and managerial document submitted by a mine operator to regulators and used internally to govern how extraction activities will be conducted over a defined period, typically annually or for the life of the mine. It details the planned mining method, production targets, equipment fleet, pit or underground design, sequencing of extraction areas, waste and tailings management, water management, blasting protocols, ventilation (for underground operations), and progressive rehabilitation commitments. The plan also incorporates safety management systems, environmental monitoring obligations, and community engagement measures required under the relevant mining law. Regulators use the MOP to assess whether proposed activities are consistent with approved environmental impact assessments and lease conditions before granting or renewing a mining permit. For bauxite and iron ore operations, the plan typically emphasizes overburden removal ratios and haul road design; for gold and diamond mines, it places greater emphasis on ore blending strategies, grade control, and security protocols given the high value and theft risk associated with the commodity. The MOP is a living document, periodically revised as geological understanding and market conditions evolve.
