Typification of Gold Deposits for Evaluation and Exploration Purposes

Abstract The issues of selecting the parameters of an exploration grid based on quantitative criteria of the degree of exploration such as the accuracy of estimation of the average grades and the error in geometrization are considered. The admissible C1 category reserves are established based on the results of the analysis of actual data. The typification of gold deposits is based on an assessment of the scale of deposits, their morphology, and fractal dimension. An assessment of the variability of the gold grade in samples or composites is also used. To assess errors in geometrization at the early stages of geological exploration, a method for their determination based on the fractal geometry and geostatistical data is proposed.
