Mineral Resources Estimation with Data and Parameter Uncertainty

  • Author / Creator

  • Uncertainty in resource estimation affects long-term development, planning, and investment decisions. Therefore, there is a need to make the best decisions considering all available data and different modeling approaches. This thesis develops a conceptual framework for resource modeling with uncertainty. A conceptual framework is presented for establishing resource uncertainty with numerical models. The framework is based on carefully assembled modeling practices to capture and represent uncertainty. An overview, concepts, and implementation aspects are presented in order to understand the nature of modeling with uncertainty, as well as provide justification for the developed modeling approaches. The integration of concepts into a modeling workflow improves the quantification of uncertainty in different input parameters and transfers the results to final resource uncertainty and sensitivity analysis. In order to demonstrate the developed concepts and workflow, two case studies are performed. The results show that workflow is effective, practical, and robust for resource modeling with uncertainty.
