Within gold ores, the element occurs in nature chiefly as native gold, which is by far the most common gold bearing mineral. In various gold ores, the native gold commonly occurs as tiny particles contained within sulfide minerals such as pyrite. Iron pyrite is an exceedingly common associate with gold, but it also serves as a reducing agent.
Gold grade of ore has a positive correlation with the abundance of NW-striking joints. The ore-hosting tuff consists of a 400 to 500 foot thick non-welded base, a densely welded central portion about 800 feet thick, and a less densely welded vapor-phase altered top that is 75-100 feet thick.
