Considerations for the Use of Sequential Sampling Techniques..These two-point statistics consist of second-order moments that are defined by a variogram. The statistics describe the lateral continuity behaviour of the models. It can be shown that the sequential sampling method correctly generates samples from a probability density function (pdf), when this p

A New High-Order, Nonstationary, and Transformation Invariant Spatial Simulation Approachand high-order spatial connectivity of the attributes of natural phenomena. Similar to multipoint methods, the proposed approach employs spatial templates and a group of training images (TI). A coarse template with a fixed number of data points and a missing value in the middle is used, where the mi

A Truly Multivariate Normal Score Transform Based on Lagrangian Flowistics. However, in the case of a set of collocated variables, marginal normality of each variable does not imply multivariate normality of the set, and a joint transformation is required. In addition, current methods are not affine equivariant, as should be required for multivariate regionalized da

Using Samples of Unequal Length for Estimationupports. All the available information should be incorporated when constructing a grade model. However, the variations in length among the samples must be considered during estimation. We propose to perform kriging using samples of different lengths. The kriging system is built using average covaria

Comparison of Two Multivariate Grade Simulation Approaches on an Iron Oxide Copper-Gold Deposity presents a comparison of a traditional multivariate simulation technique based on a model of coregionalization against another simulation in which decorrelation is first achieved by “projection pursuit,” where independent variables are simulated, then correlated back by the inverse of the decorrel

Definition of Operational Mining Unit (OMU) Sizehe size or support of the block estimate is characterized by its volume, shape, and orientation by which it is assigned a grade that directly impacts variance and resulting confidence intervals. However, local geology variations associated with operational mining configuration and production rates a

Fixing Panel Artifacts in Localized Indicator Kriging (LIK) Block Models by a two-step process that consists of averaging models with different panel origins and then performing a global re-localization. The first type of panel artifact, and probably the most important, is caused by change-of-support transformations, which are independent and applied on a panel-by-panel
