Abstract: Indicating the resources and reserves of mineral deposits and disclosing such information to the public domain is an important issue with respect to the merits of doing business in the geological and mining field. Currently in the international sphere there is a system of reporting and classification of solid mineral resources based on the Australian JORC Code. This document, honored by the stock exchanges, presents minimum standards and guidelines necessary to reliably and credibly indicate resources of mineral deposits. The JORC uses two basic categories: resources and reserves, the first of which relates to inventory (balanced resources) of the mineral and the other - to recoverable reserves - that is possible to extract taking into account the currently available technical means and the current economic criteria. The classification system is hierarchical - reserves are a subset of resources. With the gathering of geological information, the latter are distinguished into inferred resources, indicated resources and measured resources, while within the first group there are reserves classified as probable reserves and proved reserves. Measured resources and proved reserves constitute the most recognized parts of the deposits. Following the success of the JORC many countries have developed their own national standards of reporting of resources and reserves. These codes are concentrated within CRIRSCO - Committee for Mineral Reserves International Reporting Standards [solid].
