Rigorous evaluation of mining systems encompassing methods, equipment, technology, layout, and scheduling is fundamental to a mine’s economic viability and operational performance (Hartman, 1992). This evaluation progresses through distinct stages, from Scoping Studies to Definitive Feasibility Studies, with cost estimation accuracy improving from approximately ±30-50% to ±10-15% as engineering detail increases (Resource Capital Funds, 2024).
Effective evaluation directly shapes mine economics by enhancing cost prediction and control. It allows for the identification of key cost drivers such as geological conditions and equipment selection, facilitating strategic cost optimization and the establishment of appropriate cost contingencies (MSHASafetyServices, 2024).
Operationally, system evaluation is a catalyst for improved efficiency. It helps maximize resource value by optimizing ore recovery and minimizing dilution (Hartman, 1992). Furthermore, it enhances throughput via optimized production planning and scheduling (Innouriabia.com, 2025), improves equipment availability and maintenance strategies (MDPI, 2025), and bolsters safety through better ground control and risk mitigation (ICMM, n.d.).
The assessment and adoption of new technologies like automation, guided by thorough evaluation, further boosts these efficiencies. Ultimately, a continuous and comprehensive evaluation process is a strategic imperative for achieving competitive advantage and sustainable mining operations (ResearchGate, 2025).
