IN PINK QUARTZ , WHAT METAL CAN I FIND IN IT?
It's metasomatism. Homestake is hosted in Precambrian rocks that are approximately two billion years old. The main rock formations in the mine are three metamorphic rock types: Poorman, Homestake, and Ellison. 95% of the mineralization is hosted in the Homestake Formation and is intimately associated with a specific stage of quartz veining and ductile shear zones.
