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.

Greater Leeville area
Deposits of the Greater Leeville area include Leeville, Fallon, Pete Bajo and Rita K. Leeville, Pete Bajo and Rita K contain both Mineral Resources and Mineral Reserves and are currently in operation. Fallon is a Mineral Resource and in development for future mining.

Gold mineralization is hosted within Popovich, Rodeo Creek, and Roberts Mountains formations, and associated with a series of variably orientated, discordant undifferentiated dikes that are intensely argillized. Local Phase II thrust-propagated folding structurally controls the highest-grade zones of mineralization within the anticline axial planes, disseminating outwards as stratabound mineralization in favorable sub-units. Subsequent high-angle normal faulting offsets the fold-thrust package and provide feeder-style transport for the hydrothermal fluid event often hosting mineralization associated with dikes.

Pete Bajo is the down-dip extension of the mineralization mined in the Pete Open Pit and the down dip extension of the Carlin East deposit that was mined in the 1990s offset by the Bullmoose Fault. Mineralization is exclusively hosted within the lower Wispy sub-unit of the Popovich Formation, with rare occurrences in Roberts Mountain Formation. Phase II thrust-propagated folding highly attenuates the Wispy sub-unit resulting in highly discontinuous mineralization. These units are subsequently offset by a series of northwest striking apparent normal faults that dip to the northeast.

The dimensions and orientations of the modelled mineralized domains for Greater Leeville area:
Length - 40 – 4,000 m
Width - 30 – 1,900 m
True Thickness - 5 – 570 m
Approximate Strike Direction - NNE.
