Most of the Copper Mountain claims span or are adjacent to the 70 kilometer-long "Shylock Zone," a north-south-trending Precambrian structure marked by unusual stretching and ductility during the deformation events that transformed the Precambrian volcanic country rock into greenstone schist
Gold in association within greenstone schist
is viewed as being a favorable condition for large deeper deposits as found in many greenstone belt terrains throughout the world.
These are composed of various types of greenstones, greenstone schists
, spillites, diabases and mica schists.
