Multigaussian kriging is used in geostatistical applications to assess the recoverable reserves in ore deposits, or the probability for a contaminant to exceed a critical threshold. However, in general, the estimates have to be calculated by a numerical integration (Monte Carlo approach). In this paper, we propose analytical expressions to compute the multigaussian kriging estimator and its estimation variance, thanks to polynomial expansions. Three extensions are then considered, which are… Expand
A non-stationary geostatistical approach to multigaussian kriging for local reserve estimation

Two Ordinary Kriging Approaches to Predicting Block Grade Distributions
Multigaussian kriging aims at estimating the local distributions of regionalized variables and functions of these variables (transfer or recovery functions) at unsampled locations. In this paper, weExpand

This work gives practical tips for the modeling of the univariate and bivariate distributions and for the implementation of disjunctive kriging, mainly in what refers to the convergence of the expansions into factors, the post-processing of the estimated statistics and the use of ordinary kriged.

Multigaussian kriging for point-support estimation: incorporating constraints on the sum of the kriging weights
In the geostatistical analysis of regionalized data, the practitioner may not be interested in mapping the unsampled values of the variable that has been monitored, but in assessing the risk thatExpand
Shortcomings of multiple indicator kriging for assessing local distributions
Abstract This paper examines several drawbacks and limitations of indicator kriging applied to continuous variables, in the scope of the lognormal random function model. In particular, it focuses onExpand

Introduction to disjunctive kriging and non-linear geostatistics
Although linear geostatistics was first developed to tackle problems posed in evaluating bodies of ore in mines, it has since been extended to other fields of activity. Tools such as the variogramExpand
The Selectivity of the Distributions and “The Second Principle of Geostatistics”
The definition of the recoverable reserves is nearly connected with two effects of a purely physical nature: a support effect, and an information effect. For the reserves depend on the support of theExpand
The lognormal approach to predicting local distributions of selective mining unit grades
When planning highly selective mining operations, the challenge is to estimate mineable ore reserves that will be selected at the mining stage. From exploration data it is not possible to estimateExpand
The multigaussian approach and its applications to the estimation of local reserves
The performance of the geostatistical techniques of disjunctive kriging and multigaussian kriging for the estimation of local recovered reserves are compared using a simulated deposit.
Geostatistics for Natural Resources Evaluation
This paper presents a meta-modelling framework that automates the very labor-intensive and therefore time-heavy and expensive process of manually cataloging and estimating the effects of noise in a discrete-time model. Expand

A Simple Substitute for Conditional Expectation : The Disjunctive Kriging
In this paper, a new procedure for non linear estimation is proposed: it is better than the usual best linear estimation, and necessitates less prerequisites than the conditional expectation.
Uniform Conditioning Versus Indicator Kriging
This paper presents two methods concerned with local estimation of recoverable reserves which are the uniform conditioning by panel grade and indicator kriging.
