The mineral deposits along the Carlin Trend form a suite of deposits known as Carlin-type. Carlin deposits comprise stratabound disseminated gold mineralization hosted by Silurian-Devonian carbonate rocks that have been metamorphosed to varying extents. The deposits are hydrothermal in origin and are usually structurally controlled.The Pete Bajo Complex is made up of three deposits: Pete Bajo, Fence, and Full House. Pete Bajo is the down-dip extension of the mineralization mined in the Pete open pit. The Fence deposit is located to the north, about 366 m down-dip of the Pete Bajo deposit. Full House is a down-dip extension of the Carlin East deposit and is offset by the Bullmoose Fault. Lithologic units recognized in the Pete Bajo Complex include the upper portion of the Hanson Creek Formation (Ohc), Roberts Mountains Formation (SDrm), Popovich Formation (Dp), Rodeo Creek Formation (RC), and the upper plate Vinini Formation (Ohc). The majority of the gold mineralization in the Pete Bajo Complex is hosted within the lower unit of the Popovich Formation (DpW). Localized, thin intercepts are also present within the Roberts Mountains Formation (SDrm) unit. Low angle faulting along the Popovich Formation (Dp/SDrm) contact thins or removes the upper units of the DpW within various zones of Pete Bajo resulting in discontinuous mineralized strata. These units are subsequently offset by a series of northwest striking apparent normal faults that dip to the northeast. An East-West striking, sub-vertical dike swarm has also been observed across the Pete Bajo and Fence deposits.
