The Nopal I deposit is part of a Basin and Range horst composed of Tertiary rhyolitic tufts underlain by carbonate sedimentary rocks as is Yucca Mountain (Mesozoic carbonates at Nopal, Paleozoic carbonates at Yucca Mountain). Further, both the proposed Yucca Mountain repository horizon and the Nopal I deposit are located in the oxidizing, hydrologically unsaturated zone 100 m or more above the water table. The locality is similar chemically to the Yucca Mountain locality and is studied due to the chemical environment being ideal to store nuclear waste.

The Sierra Peña Blanca is located to the north of Aldama City (Chihuahua State). It corresponds to an uplifted faulted block about 80 km long and 15 to 20 km wide, of Mesozoic and Cenozoic rocks, surrounded by basins to the west and the east. The average elevation of the sierra is 1,800 m, whereas the basins are around 1,600 m and decrease gradually eastward. This sierra,as well as other sierras belonging to the Basin and Range system, presents a general northward strike, with a tilt to the west.

The Nopal 1 Deposit is confined to a breccia zone or pipe, limited to by faults. The breccia pipe is 100m high x 20m x 40m wide. The deposit is found within the Nopal Rhyolite. Uranium minerals found in the deposit are primarily oxidized.

The Las Margaritas Deposit is hosedted by the Escuadra Formation and is found on the axis of a tectonic valley.

The Puerto 3 deposit is located to the northwest of the Las Margaritas deposit and is hosted by the Nopal Rhyolite overlain by the Escuadra Formation.
Age given for the Nopal rhyolite which underlies what was previously referred to as the Escuadra Formation. The two are occasionally separated by a thin layer of pumice, but together make up what is referred to as unit 2 in the literature.
Age given for what was previously referred to as the Escuadra formation, which overlies the Nopal Rhyolite. The two are occasionally separated by a thin layer of pumice, but together make up what is referred to as unit 2 in the literature.
After approximately a 6 Ma hiatus, which is generalized in all of the surrounding areas, volcanic activity started again and formed the top part of the Escuadra Formation.
The Nopal 1 Deposit is used to describe the formation age of other similar deposits found in the Sierra Peña Blanca area, and are all found within the Nopal Rhyolite.
