The Marquis & Gilbert prospect is located at 760 metres elevation above sea level on the north side of Poplar Creek 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 Marquis & Gilbert property consist of grey mica schist, phyllite and calcareous to graphitic schist. The strata strike northwest and dip 20 to 60 degrees northeast and are cut by Mesozoic meta-andesite and metadiorite dikes. Milky white quartz veins, 0.1 to 1.5 metres wide, strike parallel to the foliation and dip between 45 degrees northeast through vertical and 45 degrees southwest. The veins have strike continuity over tens of metres and are best developed in the calcareous schist. Sulphide minerals are sparse and include pyrite and arsenopyrite. Sampling in 1981 indicated that the veins carried low gold values with the best sample assaying less than 2 grams per tonne gold over a 1-metre width (Assessment Report 9801).

A total of 15 tonnes were mined from the occurrence in 1903 and 1928. This production yielded 654 grams of gold, 1400 grams of silver and 95 kilograms of lead.

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.

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.
