Advances in Applied Strategic Mine Planning

Abstract

Assessment and management of orebody uncertainty is critical to strategic mine planning. This paper presents an approach that consists of a series of procedures for risk assessment in pit optimisation and design. Multiple block grade simulations are processed in Whittle Software to produce a distribution of possible outcomes in terms of net present value. Examples from an open pit mine are used to illustrate the practical application of the methodology.
