| Structure: | Deep Star lies along the Tuscarora Spur, a north-trending antiform., Deep Star lies 1000 ft. south of the Goldstrike intrusive and along the southern extension of the NW-trending Post fault system. The primary structural orientation associated with ore formation at Deep Star is N20W. |
| Alteration processes: | Alteration comments: propylitization, argillization, silicification. Argillization is the dominant alteration type and occurs as a halo to the mineralized zone, and with quartz through the gold-rich zones. Silica is present in a variety of forms, including replacements, veins, stockworks and breccias, reflecting multiple periods of silicification. Silicification is not a simple quartz flooding, but is found as a quartz-kaolinite-sericite alteration. |
