The Midnight (Creek D) occurrence is located on a small creek flowing north into Zinc Bay, approximately 450 metres south of the creek mouth.

The area is underlain by Mt. Ney volcanic rocks of the Lower Cretaceous Skeena Group, undivided sedimentary rocks of the Middle Jurassic Smithers Formation (Hazelton Group) and calc-alkaline volcanic rocks of the Lower Jurassic Telkwa Formation (Hazelton Group). These have been intruded by intrusive rocks of the Eocene Coast Plutonic Complex(?) to the southeast.

Locally, a shear system with associated quartz-sericite alteration hosts mineralized quartz veins. Sulphide mineralization is not described.

In 1990, a chip sample (9411) assayed 0.3 per cent copper, 0.51 per cent lead, 4.6 per cent zinc, 15 grams per tonne silver and 1.99 grams per tonne gold over 1.5 metres (Assessment Report 20146).

During 1919 through 1945, claims were staked in the area. In 1990 and 1991, Equity Silver Mines completed programs of rock and soil sampling, geological mapping and an induced polarization survey, totalling 22.6 kilometres, on the area as the Midnight claims. In 1993, Guardsmen Resources completed a 6.8 kilometres ground electromagnetic and magnetic survey on the area as the XK2620 claim. In 1999, a program of ground geophysical surveys and geochemical sampling was completed on the area as the Zincamp property. In 2006, Christopher James Gold, on the behalf of Guardsmen Resources, prospected the area as the Zinc Bay property. In 2011, Jet Gold, on behalf of Guardsmen Resources, completed a program of rock sampling and airborne magnetic and electromagnetic surveys, totalling 476 kilometres on the area.
