Fisher Mountain
Just north of Henderson Mountain in the New World Mining District is reddish colored Fisher Mountain. The mountain is formed by a complex intrusion called the Fisher Stock. It is made up of a network of felsic intrusions and breccia bodies emplaced in phases. The gold-copper deposits on Fisher Mountain are located along the margins of the stock and are associated with the skarn around the intrusive or replacements of the intrusive rock. The skarn was formed by contact metamorphism which is localized metamorphism resulting from the heat of the igneous intrusion. Oxidation of iron bearing minerals is responsible for the red hues so visible on the mountain.
