Oretonnagebased
Oretonnagebased is a framework used in mining economics to base project evaluation and planning primarily on ore tonnage. In this approach, the total mass of ore available or to be mined is treated as the central driver of feasibility, rather than focusing exclusively on ore grade or metal content.
Methodology: Starting from geological estimates of total ore tonnage, the analysis links potential production, capital and
Applications: It is used in early-stage scoping studies, prefeasibility analyses, and some contract frameworks where volumetric
Advantages and limitations: The approach offers simplicity and a direct link to production planning and budgeting.
