Geographically, the Weepah project is in the Weepah Hills southwest of Tonopah, NV in the central portion of the Walker Lane. The Walker Lane is a northwest-southeast oriented dextral shear zone situated in between the Sierra Nevada batholith to the west and the Basin and Range to the east. The Walker Lane is a long-lived structural discontinuity, subparallel to the San Andreas fault, and is associated with a series of gold and silver deposits that host over 80 M oz Au and 700 M oz Ag. The greatest concentration of mineral deposits are volcanic-hosted precious metal deposits but also include orogenic shear zone related gold deposits such as Mineral Ridge and Weepah. Mineral Ridge and Weepah are hosted in metamorphosed sediments and intrusive rocks that have been subjected to extensive folding, thrust faulting, low-angle detachment extensional faulting, and younger high-angle normal faulting.
Gold hosting metasediments at Weepah include Proterozoic rocks of the Wyman Formation, which consists of quartzites, quartz-mica schists, phyllites, calc-silicate rocks with an overlying subunit of deformed dolomite (the Reed Dolomite) (Figure 4). The Reed dolomite is itself overlain by Cambrian Campito Formation, consisting of interbedded siliciclastic rocks and quartzites, and the Poleta Formation, consisting of interbedded silty limestones, quartzite, and dolomite, as described by McKee. Metamorphic grade appears to increase down section. This entire metasedimentary sequence is intruded by Mesozoic and Cenozoic igneous rocks, including Cretaceous age quartz monzonites of the 85.3±4.3 Ma Lone Mountain series  and plutons, diorite sills, leucogranite dikes and mafic dikes of the Weepah Complex.
The Weepah district is located in a southeastern plunging anticline cored by the granitic Weepah pluton. Structure at Weepah is characterized by broad flexures, minor thrusting and high-angle faults. Deep drilling of the Weepah shear zone west of the historic mine intersected the mineralized fault zone completely within the Weepah pluton, indicating that shear zone development and mineralization post-dates magmatism. The brittle and often planar nature of the shear zone indicates that mineralization took place well after the intrusions had cooled. As such, the relative timing of mineralization may be similar to mineralization at Mineral Ridge, which postdates intrusive host rocks by ~15 Ma, occurring at 76.0±1.8 Ma.
The two known gold deposits at Weepah are; the Weepah West shear zone where the historic pit is located, and the Weepah East zone. The Weepah West shear zone is a quartz-iron oxide filled, northeast-trending, dextral oblique slip shear zone dipping ~45° to the west. Gold occurs predominantly as free grains, (or within iron oxides) in a silicified gouge zone composed of quartz and altered country rock . The quartz is multi-episodic, some crushed by later continued movement on the shear zone, and some uncrushed, presumably post-tectonic.
The Weepah East zone is characterized as a near-surface, shallowly dipping, recrystallized carbonate or carbonate replacement horizon. Less is known about Weepah East as there is no reliable bedrock and drilling has been limited to reverse circulation and erratic, fanned drill holes. Mineralization at Weepah East may be structurally controlled by one of two faults zones identified during the first phase of exploration (Figure 5). The existence of newly identified faults such as the Tailings Wash, East Weepah and Central Pediment faults has been supported by the technical teams geologic mapping, geochemistry in soils, reinterpretation of geophysics and historic drilling (Figure 6). Surface geochemistry revealed these faults may source signature elements associated with gold. Reinterpreted Controlled-Source Audio-frequency Magnetotellurics (CSAMT) showed evidence of these faults (Figure 7) and drill holes along the margins of these fault zones contain encouraging intercepts of gold mineralization.
