Trade-off Assessment for Strategic Mine Planning
Trade-off Assessment is essential for understanding the mining potential and value of any mineral deposit to establish the preferred strategic approach for advancing the project or making an investment decision. Trade-off assessment of the mining method (open pit and/or underground), production rate, cut-off value and processing approach to understand the influence on project scale, economics and environmental and social impacts is required for identifying the Strategic Mine Plan. In addition to economic assessment, important design aspects that shape strategy include future management of mine waste and tailings, technology and energy supply options, delivering sustainability goals and the mine’s post closure setting.
This presentation provides an overview of a flexible trade-off assessment approach that has been successfully applied to a wide range of mining projects, based on the available information, to enable improved visibility and confidence in identifying the best strategy for an operating mine or developing project.
