Miami-Inspiration deposit, Inspiration, Miami-Inspiration District, Globe-Miami District, Gila Co., Arizona, USA

StandardDetailedBy ChemistryMineral Photos (23)Site Photos (1)Search GoogleMineral Report for Region

The Miami-Inspiration deposit is a single, continuous deposit commonly referred to as consisting of the Live Oak, Keystone, Inspiration, Captain, Pinto, and Miami orebodies. These are divisions made mostly on the basis of property lines. The only complete separation in the orebody is that caused by the Bulldog fault, which cuts across near the middle of the orebody between the Keystone and Inspiration divisions.

In the western part, the long axis of the orebody strikes N55E, but in the eastern part the strike trends nearly east. The Bulldog fault depressed the block to the east more than 500 feet. The western segment of the orebody crops out just west of the Bulldog fault and plunges southwestward, so that the top of the ore at the west end is about 1,000 feet below the original surface. The eastgern segment is undulating but is nearly horizontal. Just east of the Bulldog fault, the eastern segment is overlain by about 500 feet of leached capping, but it crops out in an area northeast of the Pinto fault. At the eastern edn the orebody is terminated by the Miami fault along which the Globe Valley block to the east has been dropped at least 1,500 feet, bringing Gila conglomerate into contact with the mineralized schist and granite.

The long axis of the orebody appears to coincide approximately with the axis of the zone of most intense hypogene copper mineralization, which is along the contact between Pinal Schist and a lobe on the northeast side of the Schultze Granite.
