The Columbia-Evening Sun occurrence is located on the middle fork of Glacier Creek, 7.5 kilometres northeast of Stewart. A few tonnes of high-grade ore were produced between 1910 and 1913.

The occurrence is hosted in a 3 kilometre long, 2 kilometre wide Tertiary(?) augite diorite stock (Coast Plutonic Complex) that intrudes argillite and siltstones of the Middle Jurassic Salmon River Formation (Hazelton Group).

The showing consists of a 0.3 to 1.5 metre wide quartz-siderite breccia vein striking 065 degrees for 480 metres and dipping 85 to 90 degrees southeast. The vein occurs within a shear zone, up to 2 metres wide, in chloritized diorite and has been traced downdip for a vertical distance of 225 metres. The vein is associated with a parallel, fine grained, altered dike over portions of its strike length.

Mineralization consists of galena, sphalerite, pyrite and minor arsenopyrite, tetrahedrite and stibnite. The mineralization occurs as veinlets and discrete bands, up to 5 millimetres thick, locally concentrated to form higher grade ore shoots within the vein. The vein contains inferred reserves of 118,000 tonnes grading 0.69 gram per tonne gold, 120 grams per tonne silver and 3 per cent lead over a strike length of 360 metres, a dip extent of 137 metres and an average width of 1 metre. Ore shoots within the vein average 2.4 grams per tonne gold, 1131 grams per tonne silver and 20 per cent lead (Property File - Prospectus, Morocco Explorations, 1988, page 18).

A parallel quartz vein, up to 0.15 metre wide, occurs 24 metres to the southeast and contains minor sphalerite and galena. A 0.15 metre chip sample assayed 3.4 grams per tonne gold, 24 grams per tonne silver and 0.004 per cent lead (Assessment Report 15305, page 11).

Two shipments of hand-sorted ore totalling ten tonnes averaged 3.1 grams per tonne gold, 7847 grams per tonne silver, 18.06 per cent lead and 6.1 per cent copper.

Work on the Evening Sun and Columbia claims was initiated in 1906 by Rush and Bagg. In 1910, work by Lordigordy Mines, Ltd. consisted of building boarding and bunk houses to accommodate twenty men as well as a foreman’s cabin, stable, etc. Development work comprised three tunnels on the Evening Sun claim, 24, 26 and 6 metres respectively, and a 13.7 metre tunnel on the Columbia claim. In 1986, an exploration program on behalf of Silver Bar Resources Ltd. was designed to assess the mineral potential of the property beyond the main workings areas. Part of the property was mapped and prospected, two grids established, soil samples collected, and a VLF-EM survey conducted. In 2006, Teuton Resources Corp. completed 228.1 line-kilometres of a helicopter-borne AeroTEM II electromagentic and magnetic survey on their Silver Bell property which covers the showing area. During 2017 through 2020, Singer Resources Inc. and American Creek Resources Ltd. completed programs of geochemical sampling, a 13.5 line-kilometre induced polarization survey and a 438.5 line-kilometres airborne magnetic and LiDAR survey on the area as the Dunwell property.
