The June Bug prospect is located 1 kilometre west of Wolfe Creek and 12.5 kilometres south of Princeton.

The area is underlain by the eastern facies of the Upper Triassic Nicola Group, comprising mafic augite and hornblende porphyritic pyroclastics and flows. These rocks are intruded by diorite and monzonite, locally pyroxenite and gabbro, of the Early Jurassic Copper Mountain and Lost Horse intrusions.

Old workings in porphyritic microsyenite and latite of the Lost Horse Intrusions expose an area of disseminated pyrite and chalcopyrite cut by narrow magnetite veinlets. The southern part of the zone occurs in magnetite breccia. This deposit trends north-northwest for at least 60 metres. A sample from the dump of the northernmost of two shafts assayed 1.5 per cent copper (Geological Survey of Canada Memoir 171, page 44).

This occurrence was first explored by at least two shafts and a number of trenches, excavated some time between 1904 and 1934. The prospect was trenched by Cumont Mines Ltd. in 1966 and by Similco Mines Ltd. in 1990. Newmont Exploration of Canada Ltd. completed soil and magnetometer surveys over the deposit in 1987.
