The Bern occurrence is centred 630 metres west-southwest of the west end of Long Lake and 2.8 kilometres northeast of the south end of Brenda Lake. The Brenda occurrence (MINFILE 092HNE047) lies approximately 1 kilometre to the south.

The area is underlain by quartz diorite/granodiorite of the Early Jurassic Brenda stock, which is part of the Pennask Batholith.

Locally, scattered outcrops of molybdenum and copper mineralization occur over a 1000 metres (north-south) by 1100 metres (east-west) area immediately west of George and Long lakes. This mineralization consists of chalcopyrite and molybdenite, as fracture coatings or in quartz veins. Minor malachite is present throughout the mineralized area. Stronger mineralization occurs along subvertical fractures and veins striking northeast. Fractures lined with secondary biotite commonly host chalcopyrite and minor molybdenite.

Noranda Exploration Company Ltd. conducted various geological, geophysical and soil geochemical surveys over the showing between 1965 and 1970. In 1970, Arrow Inter-America completed an airborne magnetic survey, totalling 752 line-kilometres, on the area as the Tic and Toc claims. The company also drilled five holes immediately west of George Lake during this time. Geological mapping and soil sampling of the occurrence was completed by Brenda Mines Ltd. in 1981. During 2006 through 2012, Bitterroot Resources completed programs of rock, silt and soil sampling, geological mapping, 147.6 line-kilometres of ground magnetic surveys and a 66.2 line-kilometre ground induced polarization survey on the area as the North Brenda property.
