Deposit type

  • Hydrothermal

Summary:

The mineral deposits along the Carlin Trend form a suite of deposits known as Carlin type deposits.

Carlin mineral systems are a unique class of epigenetic ore deposits with enigmatic origins. They are unique due to the size and scale of deposits that formed exclusively within NE Nevada during the middle-Eocene period (42-35 Ma), establishing this area as a world-class gold complex. Carlin mineral systems are enigmatic due to their unknown, distal source of gold, as well as deposit characteristics and hydrothermal conditions that culminate to being atypical of most documented mineral systems.

Tri-Star (Silverstar and Goldstar)
The gold deposits at the Tri-Star complex (formerly Genesis) are developed along the Tuscarora, Turquoise, and Ridge anticlines within the Lynn Window. They occur over an area of about 3.2 kilometres long by 1.9 kilometres wide. The Silverstar deposit occurs in the hinge of the Tuscarora anticline whereas the Bluestar Point, Bobstar, Goldstar, and Payraise deposits occur on the more western anticlines. The anticlines are intruded in the north by the 158 Ma Goldstrike intrusion, a thick composite diorite–granodiorite sill complex.

Five major lithologic units are recognized in the Tri-Star deposit from surface mapping and drill hole logging: Tertiary Carlin, Devonian Rodeo Creek, Devonian Popovich, Silurian Roberts Mountains, and Ordovician Hanson Creek Formations.

Mineralization is preferentially developed in laminated silty limestone and bioclastic debris flows of the Popovich and Roberts Mountains Formations, but locally can also occur in contact metamorphosed calc-silicate hornfels, Rodeo Creek Formation siliceous mudstone, siltstone and calcarenite, Vinini Formation mudstone/quartz hornfels, and fractured Goldstrike intrusive margins. Gold deposits generally occur where mineralizing fluids exploited thrust faults, conjugate northwestand northeast-striking normal faults, and anticline hinge zones. The deposits have dimensions that range from about 183 to 457 metres by 61 to 183 metres. Mineralization can be stratabound locally but is typically discordant to the formations along faults with thicknesses ranging from 15 metres to 91 metres.
