They were emplaced during or after a greenschist facies metamorphism postdating the intrusion of feldspar porphyry dikes. The veins were not significantly affected by any subsequent metamorphism or tectonism.Two principal types of veins occur in the mine; subvertical veins and subhorizontal veins. They are contemporaneous and cogenetic.

The district is underlain by quartz diorite and albite granite of presumable Mesozoic age (Gillully and others, 1933, p. 57-58). These rocks intruded Permian greenstone, only remnants of which remain in the area. Columbia River Basalt unconformably overlies the older rocks. The ore deposits are gold-bearing quartz veins in the diorite and granite.

This can be an indicator of gold. Iron Staining & Gossans: Not all veins produce much quartz – gold bearing veins can consist of calcite or mostly sulfides – which often weather into iron stained spots when the pyrites convert to iron oxides. Large amounts of iron oxides like hematite, magnetite and ironstone can be favorable indicators.
The 16 to 1 mine is a gold, silver, copper, zinc and lead mine located in the Alleghany mining district in California. It is most famous for producing jewelry quality gold in quartz specimens. Gold was first discovered in the Alleghany region in 1851 by a group of Kanakas sailors who found gold nuggets in what became the Kanaka Creek.
