Altered, Upper Triassic Stuhini Group sediments and volcani- clastics are intruded by a granodiorite batholith which is part of the Cenozoic Coast Plutonic Complex. Locally, the Stuhini Group rocks are comprised mainly of biotite-rich schists, chlorite schists or amphibolite and quartz-mica schists.

Middle Jurassic or younger diorite dykes crosscut the altered Stuhini Group rocks and host disseminated pyrrhotite within the dykes and along the contact margins. The diorite is quite magnetitic and is associated with some copper mineralization. The schistose volcanics are heavily iron stained but show no traces of copper. Minor specular hematite is associated with the biotite schists.

In 2006 and 2007, Hathor Exploration Ltd. completed a 7228.7 line-kilometre airborne geophysical survey on the area as the Quillian claims of the Iskut project. In 2008, Max Minerals Ltd. examined the property.
