The Crown King prospect is located at 1035 metres elevation above sea level between Poplar and Cascade creeks in the Slocan Mining Division.
Regionally, the area lies within the Selkirk Mountains of southeastern British Columbia. The occurrence is within the Kootenay Arc, a curving belt of highly deformed metasedimentary and metavolcanic rocks which includes the Upper Proterozoic Horsethief Creek Group, the Upper Proterozoic to Lower Cambrian Hamill Group, the Lower Cambrian Badshot Formation, and the Paleozoic Lardeau and Milford groups. The volcano-sedimentary sequence is intruded by numerous Paleozoic to Mesozoic granitoid plutons.
The Lardeau River area of the Selkirk Mountains is mainly underlain by massive pillow lavas, volcanic breccia and green phyllitic rocks of the Index Formation and by grey-green mica schist of the Broadview Formation. Grey phyllitic rocks and marble of the Milford Group are exposed near the edges of the Mesozoic Mobbs Creek, Rapid Creek and Poplar Creek stocks. All rocks have undergone regional metamorphism to middle or upper greenschist facies. Rocks of the Milford Group have also been affected by thermal metamorphism (Geological Survey of Canada Bulletin 193).
Rocks on the Crown King property consist of grey mica schist, phyllite and carbonaceous to graphitic schist. The strata strike northwest and dip 20 to 60 degrees northeast and are cut by Mesozoic meta-andesite and metadiorite dikes.
Gold occurs with oxidized pyrite and galena in narrow quartz veins within calcareous schist. The showing has been explored with several trenches but gold values have not been encouraging (Assessment Report 9801).
In 1980 and 1981, Westmin conducted an exploration on the property containing the occurrence. The work included geology, soil geochemistry, and trenching.
In 2003 and 2004, Cream Minerals conducted exploration programs consisting of mapping and sampling of historic workings. Highlighted results at the Crown King occurrence included sample CK-1, a grab sample grading 9.19 grams per tonne gold, 45.0 grams per tonne silver, 0.12 percent copper, and 0.83 percent lead (Dandy, L. (2017-07-28): Technical Report on the Goldsmith Property).
In 2004 to 2006, Cream Minerals completed a soil sampling program and an airborne magnetic and electromagnetic survey.
In 2008, Cream Minerals completed nine excavator trenches on the property, focusing on the Bullock and Goldsmith areas.
In 2016 and 2017, Black Tusk Resources Inc. completed a ground geophysical survey of the property containing the occurrence.
