The historical Berkeley Pit in Butte, Montana was developed during open-pit mining of polymetallic veins that overlie a porphyry stockwork vein deposit at depth. The veins are hosted in the Butte granite, one of many granitic phases of the Boulder batholith. View is to the north-northeast.

The anomaly at Pennington Mountain is visible in the geophysical data collected in aerial surveys conducted in 2021.

The return signal from the electromagnetic pulse administered to the ground by the WalkTEM (transient electromagnetics (TEM)) instrument is displayed on the instrument during field data collection at a site in the Illinois River Basin.

A ground-based geophysics survey using WalkTEM (transient electromagnetics (TEM)) is set up and ready to initiate at a site in the Illinois River Basin.
