C1
Reserves of category C1 constitute the main part of reserves of explored and mined deposits of geological structural complexity groups 1, 2, and 3, and also can be identified in areas of detailed study of deposits of complexity group 4. The size and characteristic form of the mineral body, and main particularities of the conditions of formation and internal structure are explained; variability and possible discontinuity of the mineral body are estimated. The outline of the mineral reserves is defined in accordance with the requirements of conditions according to the results of sampling of drill holes and mine workings with consideration of data from geophysical and geochemical studies.
An „Indicated Mineral Resource? is that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. The locations are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely enough for continuity to be assumed.
C2
Reserves of category C2 are identified from exploration of deposits of all complexity groups, and in deposits of geological structural complexity group 4 constitute the main part of reserves to be included in mining. The size, form, and internal structure of the mineral body, and conditions of formation are estimated from geological, geophysical and geochemical data and confirmed by intersection of the mineral by a limited number of drill holes and mine workings. The outline of the mineral reserves is defined in accordance with the requirements of conditions according to the results of sampling of a limited number of drill holes, mine workings {e.g. trenches, pilot-scale pits}, natural outcrops or by their biota {indicator plants ?}, with consideration of data from geophysical and geochemical studies and geological structures
An „Inferred Mineral Resource? is that part of a Mineral Resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and sampling and assumed but not verified geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes which is limited or of uncertain quality and reliability.
