Abstract

The management of cash flows and risk during production is a critical part of a surface mining venture as well as an integral part of a strategy in developing new and existing operating mines. Orebody uncertainty is a critical factor in strategic mine planning, the optimization of mine designs and long-term sequencing. Traditional optimization approaches do not account for in situ grade variability or deal with geological risk. This paper presents a new approach to mine design based on risk quantification and alternative strategic decision-making criteria.
