The Crown occurrence is located on the divide between the Lillooet River and Tenquille Creek, at an elevation of approximately 2105 metres.
The area is underlain by a northwest- trending roof pendant of the Upper Triassic Cadwallader Group contained within intrusive rock, ranging from granite to granodiorite to quartz diorite, of the Jurassic to Tertiary Coast Plutonic Complex. Limestones and tuffs dip northeast and are cut by a northwest- trending shear zone.
Locally, two limestone beds (together approximately 15 metres wide) are altered to garnet-epidote-magnetite skarns and contain pyrite, sphalerite, galena, chalcopyrite, tetrahedrite and alteration products of hematite, pyrolusite and limonite. A silver-bearing vein is also reported, thought to have formed later than the skarn, but both appear to be related to the shearing. Samples of native silver are reported in association with galena, sphalerite and pyrite. The zone dips steeply east and strikes approximately north 35 degrees west.
A sample of 100 pounds representing 4.5 tonnes of ore mined had an average return from two assays of 4006 grams per tonne silver, 4.1 per cent lead and 3.2 per cent zinc (Geological Survey of Canada Summary Report 1924, page 93A).
In 1952, a general sample (no.3) from approximately 18.1 tonnes of material in a dump pile assayed 3167 grams per tonne silver, 4.8 per cent lead and 3.3 per cent zinc (Property File - A.C. Skerl [1952-09-01]: Report on the Properties of National Consolidated Base Metals Company - Near Maud Lake).
In 1969, a sample (22136) from the north wall of the south shaft assayed 4.1 grams per tonne gold, 2600 grams per tonne silver and 8.47 per cent lead over 0.3 metre (Property File - J.A. Mitchell [1969-10-16]: Report on the D Group of Claims).
In 1981, seven grab samples taken from skarn zones yielded from 0.04 to 0.18 per cent copper, 0.01 to 0.92 per cent lead, 1.0 to 140 grams per tonne silver and 0.4 to 6.7 grams per tonne gold (Property File - Tenquille Resources Ltd. [1987-06-05]: Statement of Material Facts #79/87).
The showings were explored during the 1920's via two shafts, 12 and 21 metres deep, with lateral workings. In 1952, National Consolidated Base Metals Company examined the area. The workings were reportedly un-accessible by this time. 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. 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, which covered the Gold King prospect. 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.
