The BCR occurrence is located about 40 kilometres southeast of the community of Dease Lake.

The showing occurs near the contact of the Middle Jurassic Three Sisters Plutonic Suite with Middle Triassic volcanic rocks of the Stuhini Group. Chalcopyrite with minor sphalerite, galena, and molybdenite are developed in north trending sets of fractures. Locally, the fractures have argillic and quartz-sericite alteration envelopes. Drill logs indicate the presence of pyrite, magnetite and chalcopyrite in quartz monzonite.

Stikine Minerals Corp. owned the BCR property in 1974 and Quintana Mineral Corp. was the operator. A total of 437 metres were drilled in 15 percussion-drill holes along the British Columbia railway grade and drill roads. This location is marked ‘BCR’ on Figure 3a (Fieldwork 2011, page 102).

Samples from drill core yielded low copper (less than 0.0112 per cent) and zinc (less than 0.0081 per cent) (Assessment Report 5298). The few outcrops along the British Columbia railroad grade within 1 to 2.5 kilometres north and 1 kilometre south of the drilled area are intensely iron oxide stained and contain several percent disseminated and fracture-hosted pyrite (this study; marked on Figure 3a, Fieldwork 2011, page 102). Salmon pink K-feldspar alteration developed along epidote-filled fractures is common within the plutonic rocks of the Gnat Pass area, and locally increases in intensity south of the BCR showing.

The authors of Fieldwork 2011 reported that despite discouraging drill results, the large alteration footprint of this showing warranted additional investigation.
