Target: Epithermal gold-silver deposits along a northwest striking structural corridor within the Tonopah-Goldfield Trend. Initial surficial exploration work indicates targets in three basic settings:
- the fault system separating the Paleozoic basement footwall and Miocene volcanic rocks in the hanging wall along the southwestern margin of the structural corridor.
- gold-silver deposits within the structural corridor suggested by a wide zone of shallow-level auriferous chalcedonic veins in Tertiary volcanic rocks and at the basement unconformity.
- gold-silver deposits within a set of northward-striking conjugate faults suggested by a swarm of high-level auriferous calcite veins in Tertiary volcanic rocks.

History: The Klondike North property is located at the north end of the Klondyke District. The Klondyke District is a silver district that, historically, yielded high-grade silver, lead, and gold from low angle shears and thrust faults in Paleozoic sediments. The thrust faults trend north to northeast, while younger normal faults trend east west to northwest. The district historically produced approximately 500,000 ozs Ag and 3,000 ozs Au. The district has been active intermittently since 1899.
Geology: The basement rocks of the Southern Klondyke Hills consist of the Cambrian Mule Spring Limestone beneath limestone, shale, and chert of the Cambrian Emigrant Formation. Allochthanous slate, argillite, chert, and limestone of the Ordovician Palmetto Formation lie in thrust contact above the Cambrian. Locally, Cretaceous granite stocks and Miocene rhyolite dikes intrude the basement rocks. On the northern edge of the hills, a set of north-northeast dipping faults separates basement rocks from Tertiary volcanic rocks. These faults are traceable over 12,000 feet of strike length in a corridor 1500 feet wide that extends northwestward under alluvial cover and southeastward under post-mineral flows. Oligocene ash flow tuffs, including the Monotony Tuff and Tuffs of Antelope Springs, comprise the hanging wall of basement fault contact and lie on the basement unconformity. The Middle Miocene Fraction Tuff, a sequence of lithic tuffs, lies above the Oligocene tuffs and is cut by rhyolite dikes, intrusive breccias, and domes.
The N70ºW fault appears to have been a feeder for the high-grade mesothermal style mineralization in the basement rock of the Southern Klondyke Hills, but also controlled Tertiary hydrothermal mineralization in the structural footwall and in the hanging wall volcanic rocks.
