Indicator Kriging and other new geostatistical tools

Journal Article


Abstract


  • Geostatistics is now widely used in the mining industry in the estimation of ore reserves and terms like kriging, variogram and estimation variance are becoming well known. Ordinary Kriging (OK) has been found by some practitoners to be a superior tool compared with other ore reserve estimators. However, kriging has not been the ultimate solution to difficulties which may arise in ore reserve estimation. Several additional geostatistical techniques have been recently developed for more efficient ore reserve estimation in some deposits, especially gold and other precious metals. These include indicator kriging and probability kriging which are useful tooks to work with in a selective mining operation. -Authors
