Ore controlOre is localized by a fault contact where faults intersect brittle Eureka Quartzite. Drag zones along fault and fracture intersections acted as solution channels.

StructureSeveral fault sets have complexly cut the roacks in the Reveille area, with prominent sets trending N-S, NW, NE, and E-W. In particular, the NE-trending faults that cut the Eureka quartzite in the vicinity of the Gila and New Reveille mines may have contributed to ore formation. Also, five major zones of E-W-faulting ahcut across the entire range and have exerted much structural control in channeling mineralizing solutions.
AlterationAlteration of rocks in the ddistrict is extensive and includes at least four types:\n1. extensive silicification of dolomite to jasperoid with some accompanying hematite staining. \n2. sericitization nad pyritization of dacite, as well as propylitization causing formation of a chlorite-calcite-hematite-some pyrite assemblage. \n3. kaolinization and other clay-alteration of rhyolite and quartz latite tuffs; also sericitization of same host rocks\n4. kaolinization, sericitization, and silicificationof the silicic intrusive rocks.
