The area is underlain by porphyritic volcanic rocks of the Saddle Hill volcanics, an informal subdivision of the Lower to Middle Jurassic Hazelton Group (Geological Survey of Canada Open File 2322).
One showing contains bornite and chalcopyrite in carbonate-filled fractures cutting pyritized volcanic rocks. A second showing, located 1100 metres to the northwest, contains chalcopyrite in sericitized porphyritic rock which could be subvolcanic (Assessment Report 4098).
In 2019, Pacific Empire Minerals consolidated 90 square kilometres of contiguous claims in the Babine copper-gold porphyry district into its Paragon copper-gold project (093M 020, 135, 145) after amalgamating its Wasp property and recently optioned Nilkitkwa property with six claims of newly staked ground.
