Abstract

Errors arising in the exploration of ore deposits can be divided into two groups: errors in determining specific quantitative characteristics of mineralization (average thickness, grade, density) and errors in iden- tifying the conditions of occurrence, shape and structure of ore clusters. This article discusses the reasons for the non-confirmation of explored reserves for individual blocks of ore bodies of the Charmitan gold deposit. The calculated parameters and ore and metal reserves are compared in the framework of proven reserves for four ore bodies with unconfirmed reserves. The main discrepancies in ore and metal reserves, non-confirmation of body thick- nesses and gold grades, as well as a complex of factors are considered: the density of the exploration network, and statistical and spatial variability of useful components.
