Typification of gold deposits for evaluation and exploration purposes

The issues of choosing the parameters of the exploration network based on quantitative criteria of exploration: the accuracy of the assessment of average grades and the error of geometrization are considered. Acceptable values of criteria for 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 gold grade in samples or composites is also used. To assess geometrization errors at the early stages of geological exploration, a method for determining them based on the positions of fractal geometry and on the results of geostatistical studies is proposed.
