Abstract: The Fourth of July Prospect, located in the Humboldt Range near Unionville, Nevada has structurally controlled mesothermal quartz veining that hosts ore-grade gold, silver and antimony mineralization. Three areas of this prospect were studied to characterize the geologic structure of the veins: the Black Warrior mine, Marigold mine and Congress Canyon. Across these three areas northwest-trending steeply-dipping strike-slip faults were identified as being the primary structures that host mineralization.  These three areas have unique structural characteristics with some similarities and were possibly formed from Cretaceous-aged movement along regional Jurassic-aged structural fabric remnant from the Fencemaker Allochthon event.
