The Wonder showing, located southeast of Tenquille Creek on Mount McLeod, occurs within a region underlain by a roof pendant of Upper Triassic volcanic and sedimentary rocks of the Cadwallader Group. The pendant is contained within intrusive rock, ranging from granite to granodiorite to quartz diorite, of the Jurassic to Tertiary Coast Plutonic Complex. In the area of the Wonder showing, rocks consist of metamorphosed andesitic volcanics and limestone with interbedded quartzite and slate. Metasedimentary rocks are tightly folded and plunge 70 degrees to the northwest.

Discontinuous, 15-centimetre wide veins are mineralized with sphalerite, galena, chalcopyrite, pyrite and limonite at the skarnified contact between limestone and slate and quartzite beds. The best sample taken from these veins assayed 11.3 grams per tonne silver, 0.07 per cent copper, 0.19 per cent lead and 0.11 per cent zinc (Assessment Report 17261).

The area has been explored since the 1920s. In 1952, National Consolidated Base Metals Company examined the area. In 1961, Phelps Dodge completed a program of geological mapping on the area as the Tenquille claims. In 1969, the area was examined as the D group. Some drilling and blasting were performed at this time. In 1982 and 1983, Tenquille Resources completed programs of ground geophysical surveys, prospecting, trenching and sampling on the area as HIAG claims. In 1987, Ajax Resources completed a program of rock and soil sampling, geological mapping and ground geophysical surveys on the area. In 1989 and 1990, New Camp Resources completed programs of rock, silt and soil sampling and ground geophysical surveys on the area as the Zul property. In 1990, Teck Corp. staked the Apollo, Sun and God claims of the Sungod property. In 2003, the area was staked as the Gold King property by J.T. Shearer. During 2004 through 2006, Goldking Mining Ltd. (later Wolverine Minerals Corp.) completed programs of rock and soil sampling, geological mapping and an induced polarization survey on the area.
