The Bow occurrence is located about 92 kilometres southeast of Dease Lake.

In the area of the showing, upper Permian to Lower Triassic Kutcho assemblage mafic to felsic metavolcanic rocks and sediments underlie Upper Triassic Sinwa Formation limestone and Lower Jurassic Inklin Formation phyllites. The area is interpreted to have been isoclinally folded during formation of the King Salmon allochthon in Early to Middle Jurassic time. The Sinwa Formation has recently been assigned to the Stuhini Group (Stikine Terrane) and the Inklin Formation to the Laberge Group (Overlap Assemblage). See the Kutcho Creek deposit (104I 060) located 13 kilometres east for details of the new age date for the Kutcho assemblage.

A 1975 drillhole intersected pyrrhotite-rich strata. In 1976, diamond-drill hole 33 on the Bow 34 claim intersected, at 95 to 99 metres depth, a quartz vein in quartzite hosting minor bornite and chalcopyrite. The drillhole initially passed through graphitic shale, calcareous siltstone, calcareous sandstone and phyllite before entering the quartzite. The hole ended in phyllite at 104 metres. The hole, inclined 50 degrees south, was collared in the Inklin Formation, but at 94 metres entered a succession logged as quartz-sericite phyllite, quartzite and chlorite-calcite phyllite, which is probably part of the underlying Kutcho assemblage. The mineralization is within this lower interval, and is described only as “minor bornite and chalcopyrite in one quartz vein” (Fieldwork 2011, page 95).

Imperial Oil drilled one hole each in 1975 and 1976 on the Bow 5 and Bow 34 claims, respectively.

In 2008-10, the occurrence was explored by Kutcho Copper Corp. as part of the Kutcho property (Accent 1 claim). For a complete exploration history see Kutcho (104I 060) or Assessment Report 31282.
