The location of the Silver King showing is uncertain but is currently mapped as being on the northeast face of Mount Edgar, east of Chilliwack Lake.
The area is underlain by the Custer Gneiss, a package of rocks derived from Mesozoic and possibly Paleozoic rocks and metamorphosed in the Late Cretaceous and early Tertiary. The granodioritic Oligocene Chilliwack Batholith intrudes the country rock.
Mineral outcroppings at the headwaters of Silverhope (Silver) Creek are reported to consist of galena in quartz and quartzite. The quartzite contains crystals of pyrite. Two adits were driven; the lower adit for 17 metres with two crosscuts (25 and 6 metres), and the upper adit for 4.6 metres. Samples yielded a trace of gold and silver and no copper (Minister of Mines Annual Report 1915, page 305).
In 2015, float samples (K880154 to K880158) from the area assayed up to 301 grams per tonne silver, 4.13 per cent zinc, 0.935per cent lead, 0.18 per cent copper and 0.873 gram per tonne gold (Assessment Report 32420)
During 2010 through 2012, Miocene Metals completed programs of rock and silt sampling, and 1296.6 line-kilometres of airborne geophysical surveys on the area as part of the Southern Properties project, Custer Ridge East area.
