Ores MineralsOre veins are completely made up of a single type of ore: poor, normal or rich. When the world generates an ore vein, it has a 20% chance to be rich, a 30% chance to be poor, and a 50% chance to be normal. One poor ore produces 15 metal units, one normal ore produces 25 metal units, and one rich ore produces 35 metal units. Veins and Clusters

ShaleShale is a finegrained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals and tiny fragments ( silt sized particles) of other minerals, especially quartz and calcite. [1] Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness.
Ore Minerals : What are Ore Minerals? · An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth; they are then refined (often by smelting) in order to extract the valuable elements.
