Mineral Resource Evaluation Master Class

The Capital Empire Sandton, Johannesburg, South Africa,
12 - 15 June 2017

Mineral Resource Evaluation Master Class

Based on practical geostatistical methods proven worldwide, this modern training course will prepare and equip you with the necessary knowledge and techniques to accurately estimate and evaluate mineral resource to best practices standards.

This course covers the principles and techniques applied in the process of Mineral Resources Evaluation. Issues as to the stages of evaluation in the value chain are described. Sampling of particulate materials and the necessity of compliance with the principles in the Theory of Sampling, an understanding of error and bias, and insights to QAQC are examined. Statistical valuation of mineral deposits including estimation of population parameters and significance testing, cut-off grades and determination of grade-tonnage curves for normal and lognormal distributions are explained with desk-top examples. Approaches to univariate and bivariate statistics are examined with an emphasis on exploratory data analysis. Aspects of geological domaining, stationarity and trends, together with the necessity for compositing, declustering, debiasing, despiking are considered. The first section of the course concludes with a discussion of the necessity of numerical modelling.

The theory of regionalised variables and the underlying principles of geostatistics are examined through consideration of inverse distance estimation techniques, their nature, validity and confidence in the estimates. The number of samples used, maximum distances, the effects of clustering, anisotropy, outliers, skewed distributions, the regression effect and volume-variance effects are considered. The derivation, use and application of experimental and model variograms are described. The concepts of Ordinary Kriging and Simple Kriging for the for the mining industry are considered. The processes of cross-validation and concerns about the volume-variance effects, conditional bias, and the regression effect are considered.

The multivariate Gaussian approach to mineral resource evaluation as well as the post-processing of Multi Gaussian kriging and interpretation of results as a basis for understanding uncertainty is described. The differences between estimation and simulation are a precursor to a discussion of conditional simulation which is followed by a discussion on post-processing simulation outputs, an interpretation of the results, and an understanding of estimation uncertainty. Issues around optimisation of data spacing and the effects of changing cut-off grades on deposit value are explained. Mineral Resource and Reserves Classification and the associated uncertainty, together with the application of loss functions in risk and uncertainty models, and the financial implications of misclassification are described
