Located on the western flank of the Boulder batholith of southwestern Montana, the mineralized breccia "pipe" is opened by the Obelisk Mine. The intersection of two fault systems in the quartz monzonite of the Boulder batholith has provided the locus of the breccia "pipe". There is fairly conclusive evidence indicating that the present outcrop of the "pipe" lies only a few hundred feet below the former "roof" of the batholith.
