Ore control"North- and northwest-striking Basin and Range normal faults, with minor or no offset, are the most important structural controls. The Golconda Thrust is not thought to be important as an ore control. Beds of calcareous conglomerate in the upper portions of the antler sequence host a majority of the ore, but parts of the Valmy Formation and lower Antler Sequence also host ore.\n"

Structure"Golconda Thrust Fault", "North- and northwest-striking Basin and Range normal faulting are evident inthe mine area."
Alteration"Host rocks have been subjected to decarbonation, argillization, silicification, and supergene oxidation. Partial removal of carbonate from originally calcareous rocks preceded gold mineralization and resulted in increased porosity and permeability. In some ore zones, intensely argillized rocks above and below mineralization may have served as impermeable seals to confine later gold-bearing hydrothermal fluids. Silicification may be coeval with gold deposition and is represented by local replacement of favorable lithologies and jasperoid development in fault zones. Oxidation is thought to be supergene, but the possibility of hypogene oxidation is not ruled out."
