| Statistical presentation | |
| Data description | Statistical information on depletion of the ores, minerals and fossil fuels which represent a limited, non-renewable resource. In the context of the European economic environmental accounts it aims to collect primary data necessary to compile accounts on non-refundable underground assets of minerals and ores in natural and value terms. Reserves of natural resources are calculated and evaluated as the bowels, without taking into account losses during extraction and processing (enrichment). |
| Classification system | - ‘Classification of reserves and resources of solid underground resources’ drawn up in accordance with the Act on the Underground Resources. - NACE.BG 2008 /2 digits/. |
| Sector coverage | Exhaustive survey covering all economic entities - holders of concessions for extraction, and companies that have reported receipts from extraction activity for the previous reference year. |
| Statistical concepts and definitions | Reserves and resources of underground natural resources - are minerals and ores deposits in the ground or on the ground with a specific geological knowledge about them and economic interest. The following classifying categories exist: Reserves – That part of the underground resources, which are expected to be extracted commercially with some degree of certainty. Proven reserves - Such reserves about which is found they can be technically and economically producible with a high level of certainty (90% or more) given the current technology and relative prices. Probable reserves - reserves are not proven yet, but regarding which is estimated to have more than 50 % chance of being technically and economically producible. Resources - possible reserves, which are at present not regarded as probable but are estimated to have a significant, but less than 50 % chance of being exploitable. |
