From the long-standing debate of simulation vs estimation, to the growing focus on geological uncertainty and hierarchical truncated plurigaussian simulation, this episode explores where the mining industry stands \u2014 and where it still needs to improve. \u23f1 Key Topics 00:00 \u2013 Introduction: Simulation in mining and why uncertainty matters 01:18 \u2013 Simulation vs estimation: what\u2019s the real difference? 02:16 \u2013 The \u201cspace of uncertainty\u201d: grade, geology, parameters and planning 03:34 \u2013 Are we misleading stakeholders by ignoring uncertainty? 05:34 \u2013 Has grade uncertainty been solved? Two-point vs multipoint simulation 06:39 \u2013 Data uncertainty: blast holes, nugget effect and sampling quality 07:30 \u2013 Parameter uncertainty and spatial bootstrapping 09:43 \u2013 Geological uncertainty: why it\u2019s fundamentally different 10:44 \u2013 Plurigaussian and hierarchical truncated plurigaussian simulation (HTPGS) 12:51 \u2013 Industry adoption and emerging trends 13:08 \u2013 The \u201choly grail\u201d of a comprehensive uncertainty model 14:47 \u2013 Digital twins and the future of integrated uncertainty modelling \ud83d\udc4dIf you enjoyed this discussion, please Subscribe to Fresh Thinking wherever you listen to podcasts, for more mining-focused technical discussions across the mine value chain.
