Conditioning by the Panel Grade for Recovery Estimation of Non-Homogeneous Orebodies, It is shown that the weight assigned to the mean in a simple kriging of the panel to be estimated can be used to judge whether the data are dense enough. For panels where the data are not dense enough, the results given by most non-linear methods are strongly attracted toward the overall mean, whic

NICE

Recoverable Reserves Estimation at an Australian Gold Project,t. In the first phase of the study, only the global recoverable reserves could be evaluated. The generalized permanency of the distribution model was used for the change of support. When more data became available, the local recoverable reserves could be calculated using ‘uniform conditioning’.

Comparing Estimated Uranium Grades with Production Figures, grid with the actual production figures from a uranium deposit in Saskatchewan, Canada. The grades of blastholes on a 3m x 3m grid and a conditional simulation which provided a numerical model of the variability of grades, were also used. This additional information made it possible to experimental

Global Recoverable Reserves: Testing Various Changes of Support Models on Uranium Data,gaussian, gamma, negative binomial, mosaic) have been tested on skewly distributed uranium data. They gave satisfactory results for the global estimates of the recoverable reserves. The slight differences between the models were due to the differences between the hypotheses for the four models.

This turns out to be poorly defined. The first order variogram, which also has been considered, is curiously similar to the usual variogram, where
