Vitrain coal

type of coal rock type which is characterized by a brilliant black lustre and composed primarily of the maceral group vitrinite, which is derived from the woody tissue of large plants. Brittle and tends to break into angular fragments; however, thick layers show conchoidal fractures (that is, curving fractures that resemble the interior of a seashell) when broken. Occurs in narrow, sometimes markedly uniform, bright bands that are about 3 to 10 mm (about 0.1 to 0.4 inch) thick. Probably formed under somewhat drier surface conditions than did the lithotypes clarain and durain. On burial, stagnant groundwater prevented the complete decomposition of the woody plant tissues.

Clarain coal

Coal rock type which has an appearance between those of vitrain and durain and is characterized by alternating bright and dull black laminae (thin layers, each commonly less than 1 mm thick). The brightest layers are composed chiefly of the maceral vitrinite and the duller layers of the other maceral groups, liptinite and inertinite. Exhibits a silky lustre less brilliant than that of vitrain. It seems to have originated under conditions that alternated between those in which durain and vitrain formed.

Fusain coal

Coal rock type which is commonly found in silky and fibrous lenses that are only millimetres thick and centimetres long. Is extremely soft and crumbles readily into a fine, sootlike powder that soils the hands. Is composed mainly of fusinite (carbonized woody plant tissue) and semifusinite from the maceral group inertinite, which is rich in carbon and highly reflective. It closely resembles charcoal, both chemically and physically, and is believed to have been formed in peat deposits swept by forest fires, by fungal activity that generated intense heat, or by subsurface oxidation of coal.

Durain coal

Coal rock type which is characterized by a hard granular texture and composed of the maceral groups liptinite and inertinite as well as relatively large amounts of inorganic minerals. Occurs in layers more than 3 to 10 mm (about 0.1 to 0.4 inch) thick, although layers more than 10 cm (about 4 inches) thick have been recognized. Are usually dull black to dark gray in colour. Is thought to have formed in peat deposits below water level, where only liptinite and inertinite components resisted decomposition and where inorganic minerals accumulated from sedimentation.

Inferred

Mineral Resource is the 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 assumed but not verified geological or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes which may be of limited or uncertain quality and reliability.

Indicated

This type of resources are simply economic mineral occurrences that have been sampled (from locations such as outcrops, trenches, pits and drillholes) to a point where an estimate has been made, at a reasonable level of confidence, of their contained metal, grade, tonnage, shape, densities, physical characteristics.

Measured

Type of resource that are indicated resources that have undergone enough further sampling that a 'competent person' (defined by the norms of the relevant mining code; usually a geologist) has declared them to be an acceptable estimate, at a high degree of confidence, of the grade, tonnage, shape, densities, physical characteristics and mineral content of the mineral occurrence.

Probable

Reserve that is the part of indicated, and in some circumstances, measured mineral resources that can be mined in an economically viable fashion. It includes diluting material and allowances for losses which may occur when the material is mined. This has a lower level of confidence than a Proved Ore Reserve but is of sufficient quality to serve as the basis for decision on the development of deposit.

Proved

Ore Reserve is the part of Measured resources that can be mined in an economically viable fashion. It includes diluting materials and allowances for losses which occur when the material is mined. Reserve represents the highest confidence category of reserve estimate. The style of mineralization or other factors could mean that Proved Ore Reserves are not achievable in some deposits.
