Highgrade gold (lode mineralization style) occurs in quartzcarbonate hydrothermal breccias, veins, and in fragments of vein quartz and wall rock within fault structures. This style is common in the Main Zone and Stockwork Zone. Visible gold, electrum, and argentite have been observed and coarse visible gold is not uncommon on the property.
The deposits in the Sierra Nevada were mostly goldquartz veins formed through hydrothermal deposition (Alpers, Hunerlach, May, Hotheim, 2005). Many prospectors claimed that a person could tell the difference between potentially gold rich quartz (deemed "live" quartz) and "dead" quartz just by looking at a sample (Hill, 2006).
