Newera Resources intercepts thick coal in Mongolia - Proactiveinvestors (AU): "Newera Resources (ASX: NRU) has intersected two main, shallow coal seams totalling 26 metres in length at its Shanagan East Project in Mongolia.
The coal in this particular drill hole has a field interpreted brightness of C1 to C3, with C1 an estimate of greater than 90% brightness and C3 an estimate of greater than 40% but less than 60% brightness.
The brightness of coal is measured against a brightness index and measures light reflectivity, which is indicative of the ash content. The brighter the coal, the lower the ash content and the more energy it produces, therefore it is more valuable.
