The King is a small past producer, part of a group of small galena-quartz veins on and around Goat (Arrow) Mountain just north of Creston. The King vein is unusual in being located at the foot of the mountain, on the west side just south of Alice Siding and very close to (partly covered by) the main Creston-Salmo highway, at an elevation of 575 metres. The original discovery produced from a winze (now covered by the highway); there was another irregular vein discovered 1.6 kilometres to the north.

The veins are hosted by Middle Proterozoic Purcell Supergroup sedimentary rocks of the Middle Aldridge Formation, and the Moyie intrusions, comprising respectively, quartzofeldspathic wacke, quartz wacke and argillite, and diorite sills. The main showings consist of local concentrations of galena and pyrite with minor chalcopyrite in a quartz vein traced over 120 metres strike length and 0.6 metre wide; the northern showing consists of lower grade galena mineralization in an irregular quartz vein in a diorite sill.
