The Exodus mine is a part of the Carlin complex.

The Carlin complex is operated as a joint venture (JV) through Nevada Gold Mines which was formed in 2019. Barrick is the JV operator and owns 61.5%, with Newmont owning the remaining 38.5% JV interest.

Deposit type

  • Carlin-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.

Exodus has both Mineral Resources and Mineral Reserves and is currently in operation, whereas Green Lantern is a Project, which has Mineral Resources.

Mineralization is preferentially hosted in Popovich, Rodeo Creek and Roberts Mountains units, with locally discrete zones of mineralization associated with pre-mineral dikes of various composition and orientations. Both deposits exhibit strong structural controls on mineralization with emphasis on the high-angle Castle Reef Fault. Pre-mineral dike swarms of various compositions utilize this structure further promoting permeability enhancement through the development of dissolution and fault breccia. The Castle Reef Fault acts as a hard western boundary for both deposits with discernible offset through later reactivation, juxtaposing Roberts Mountain against favorable Popovich and Rodeo Creek formations. Tight to isoclinal folding of Rodeo Creek and Popovich formations occur in the eastern fault block. Locally complex Phase II thrust-propagated folding focuses mineralization within the intersection of favorable sub-units and local axial planes.

The dimensions and orientations of the modelled mineralized domains for Green Lantern and Exodus deposits:
Length - 840 – 1,420 m
Width - 240 – 510 m
True Thickness - 60 – 460 m
Approximate Strike Direction - NNW.
