The DBC occurrence is located on the ridge between Kliyul and Porphyry creeks, 16 kilometres southeast of Johanson Lake. It is hosted in the northwest end of a large, elongate, ultramafic-mafic pluton referred to as the Abraham Creek complex, which intrudes volcaniclastic and volcanic rocks of the Upper Triassic Takla Group (EMPR Fieldwork 2003, pages 83-100). The pluton in this area comprises a complex mixture of clinopyroxenite, hornblendite, pyroxene gabbro and diorite. The DBC occurrence encompasses several narrow quartz veins and shear zones, sparsely mineralized with pyrite and chalcopyrite, which were documented during an exploration program by Teck Explorations Limited in 1990 (Assessment Report 21521, Davie-Bear Creeks area). The highest gold value from an in-situ sample within this cluster came from a chlorite-quartz-carbonate-altered shear zone that contains trace chalcopyrite and pyrite, along with malachite, azurite and magnetite. This sample contained 4.7 grams per tonne gold, 24.4 grams per tonne silver, and 3.06 per cent copper (Assessment Report 21521, Sample R134). A nearby sample mineralized with pyrite, malachite and magnetite, collected during a 2003 mapping program by the B.C. Ministry of Energy and Mines yielded 1.26 grams per tonne gold, 14.4 grams per tonne silver, and 1.09 per cent copper, as well as 0.066 gram per tonne platinum and 0.075 gram per tonne palladium (Fieldwork 2003, pages 83-100, Sample 03PSC-54).

In 1990, Teck Exploration Limited geologists Lynn Grexton and Paul Roberts, prospector Ted Archibald, and 2 geology students spent 363 man-days on the Porphyry Creek project (Assessment Report 21521). Claims included Karen3, Lady Diana 1-4,6, Bear, Kliyul, Emer 1-9 and Lemdi. This claim group contains the following mineral occurrences, 094C): Porphyry Creek (094C 007), Croydon (094C 008), Bloom Cirque (094C 039), Porphyry Creek Molybdenum (094C 065), Croydon North (094C 066), Sarah (094C 075), Bloom Cirque Skarns (094C 084), Raven (094C 127), South Sarah (094C 128), Jump (094C 154), Rave (094C 155), Lonely (094C 156); and 094D: Lady Diana (094D 092), South Soup (094D 105), Davie Creek Moly (094D 113), Aupper (094D 139), Karen Creek (094D 145), DBC (094D 177), UPC (094D 183). Teck staff collected collected a total of 558 rock, 1372 soil/talus fines, 22 silt, 74 moss matte, 7 pan and 10 water samples. An additional 1005 soil/talus fines samples were collected from the Raven grid. Twenty-two rock specimens were sent for thin section examination. Sixteen whole rock analyses were completed.

In 1992 Noranda carried out 1:5,000 scale geological and alteration mapping and in 1993, they drilled 6 reverse circulation holes on the Kliyul skarn zone (Assessment Report 23033) and followed up with an airborne magnetic, EM, and radiometric survey that extended to the south (Assessment Report 23379). This airborne survey also covered (or nearly covered) 25 MINFILE occurrences including South Soup (094D 105), Lady Diana (094D 092), Karen Creek (094D 145) and DBC (094D 177).

Refer to Croy (094D 015) and Soup (094D 105) for related geological and work history details of the Croy-Bloom property held by NorthWest Copper Corp. (Serengeti) from 2002 to date (2021). Also see Dave Creek Moly (094C 113).

On March 5, 2021, NorthWest Copper Corp. (formerly Serengeti Resources Inc.) and Sun Metals Corp. announced that they had completed their previously announced merger.
