24 – (English) Conditional simulation and uncertainty in the ore body by David Barry


Listen Later

Uncertainty in the ore volume is a big part of the risk in a mining project. That is why in this episode we interview David Barry, senior geostatistician currently working for Geovariances, to explain about conditional simulation as one of method used in the mining operation to better estimate the ore body.

  • (02:10) About kriging, estimation, and simulation;
  • (06:40) The differences in between geostatistic and conventional simulation;
  • (09:30) Why conditional simulations are required to model ore body?;
  • (13:20) Successful stories about ore body simulations;
  • (17:30) How the simulation results are optimized;
  • (23:50) Alternative methods to deal with unbalance drill holes distribution.
