Abstract
The aim of introducing the weighted jackknife ordinary kriging (WJOK), as a robust estimator, is to solve the outlier and the problems of uncertainty associated with grade estimates of mineral resources. Jackknifing the ordinary kriging (OK) estimates and weighting the pseudo-value yield more reliab ordinary kriging (JOK) estimates. The new estimator is more conservative than the standard jackknife technique, which is shown by a little standard deviation value. It obtains a simple way to calculate the confidence interval associated with the estimation.
