The HA showing is located 4.8 kilometres north of McLeese Lake near the eastern margin of the Stikinia Terrane.

The dominant rock types in the region are metabasalt, limestone and argillaceous metasediments of the Pennsylvanian to Triassic Cache Creek Group. These are intruded by the dioritic to quartz dioritic Granite Mountain Pluton and the (?)Cretaceous Sheridan Creek Pluton. The Granite Mountain Pluton has been affected by regional metamorphism (greenschist facies) and deformation along with the enclosing Cache Creek Group.

The HA showing occurs in an area largely underlain by Miocene plateau basalt. The copper and molybdenum mineralization suggests that part of the Granite Mountain Pluton also underlies the area. No other geological information is available.
