The Hamp Mines are aligned along the Hamp Fault, which lies along the north flank of Hicks Dome. The fault is very poorly exposed and was primarily mapped through mine notes and previous reports by Baxter and Desborough (1965), Weller et al. (1952), and Bastin (1931). The fault strikes almost due east–west circumferential to the dome and dips to the south at 60° to 75° (Bastin 1931). Because the Hamp Fault trends circumferential to Hicks Dome, Denny et al. (2010) suggested the fault was related to the domal or circular uplift at Hicks Dome. The numerous small exploration pits in the area and the relocation of the roads made it difficult to accurately locate the early shafts and pits cited by various sources.
