Mining & Extraction
Mining at the Morvarid Iron Ore Mine goes beyond a production-driven operation, reflecting the integration of geological knowledge, operational experience, and applied technology.. Following the completion of exploration datasets, extraction activities commenced with a high level of precision. Optimized mine designs and AI-assisted analytical tools have enhanced decision-making accuracy while simultaneously reducing waste stripping volumes and minimizing environmental impacts.
At the core of mine planning lies the development of the mineral deposit block model, which serves as the backbone of extraction strategy. By discretizing the orebody into three-dimensional blocks, the model delivers a detailed representation of grade distribution, tonnage, density, and economic value. This enables mining engineers to rigorously evaluate alternative extraction scenarios and optimize operational outcomes with a high degree of confidence.
Key Elements in Block Model Optimization
- Accurate block grade estimation using advanced geostatistical methods such as IDW, Kriging, Sequential Indicator Simulation (SIS), and Multiple-Point Statistics (MPS);
- Incorporation of technical and operational constraints, including cut-off grade, dilution, and operational recovery factors;
- Utilization of industry-standard modeling software, including Datamine Studio RM, Surpac, and Vulcan;
- Continuous model validation through grade control data, combined with sensitivity analysis to manage and quantify geological uncertainty.
In parallel, final pit design represents the intersection of engineering, economics, and environmental stewardship. This process goes beyond defining extraction limits; it delivers an integrated framework in which maximum economic value is achieved while fully complying with safety standards, environmental considerations, and geotechnical requirements.
Key Factors in Final Pit Optimization
- Economic and technical optimization of the mining boundary based on the block model, stripping ratio, and global commodity prices;
- Sustainable engineering design of slopes and haulage systems, including bench geometry, access ramps, and geotechnical stability criteria;
- Application of advanced optimization algorithms and software, such as Lerchs–Grossmann, Milawa, GEOVIA Whittle, and NPV Scheduler, to define the ultimate pit limits and phase sequencing.
This integrated approach has positioned the Morvarid Mine among the country’s leading operations in terms of engineering precision, productivity, and adherence to sustainable mining principles—where science, technology, and experience converge to enable responsible and intelligent extraction of Earth’s resources.
