The King Solomon showing is 2 kilometres east of the Similkameen River and 16 kilometres south of Princeton.

The area is underlain by the eastern facies of the Upper Triassic Nicola Group, comprising mafic augite and hornblende porphyritic pyroclastics and flows. These rocks are intruded by diorite and monzonite, locally pyroxenite and gabbro, of the Early Jurassic Copper Mountain and Lost Horse intrusions.

This showing is hosted in diorite of the Copper Mountain stock (Copper Mountain Intrusions), about 400 metres southwest of the stock's contact with Nicola Group volcanics. The stock is intruded by several basalt dykes and quartz porphyritic felsite dykes in the vicinity of the showing.

The diorite is fractured and cut by small veins of pegmatite and epidote. Mineralization consists of disseminated chalcopyrite, bornite and magnetite in a zone 12 metres wide. The copper content is estimated to be below 1 per cent in most of the old workings (Geological Survey of Canada Memoir 171, page 46). Gold and silver values are also reported (Minister of Mines Annual Report 1908, page 125).

The workings consist of a number of trenches, three shafts and one 58-metre long tunnel excavated between 1900 and 1934. Some diamond drilling was also conducted during this time.
