Microscopic view of pyrite (FeS2) and arsenopyrite (FeAsS) grains (black, 2 mm across) in ore grade schist from Macraes gold mine. The gold occurs as micron sized grains in the pyrite and arsenopyrite. Thin black seams are rich in graphite that was introduced into the rock by hot water during deformation.

Schist is a type of rare metamorphic rock that forms in thin strata underground. It is known for being extremely rich in resources, making it very valuable to find, despite its rarity. Schist strata formation is controlled by a perlin noise function. This means that they are unpredictable to locate, but you are guaranteed to find them at some point. Although if …
