The Bullock prospect is located at 1065 metres elevation above sea level, 1 kilometre south of the Poplar Creek bridge on Highway 31 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 Bullock 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. Milky white quartz veins, all less than 1.5 metres in width, cut the schist parallel to the foliation but dip at various angles to the southeast. Pyrrhotite, pyrite and arsenopyrite are irregularly distributed throughout the veins and small amounts of ankerite and mariposite are also present. The veins locally carry minor amounts of galena and sphalerite and occasionally free gold is found in small pockets of decomposed iron-stained material and along the contact of the quartz with the schist. A 50-centimetre chip sample taken across a mineralized quartz vein assayed 14 grams per tonne gold and 10 grams per tonne silver (Minister of Mines Annual Report 1927). The property has been explored by numerous trenches and at least 6 adits totalling 365 metres in length.

Work in 1952 identified the presence of lead, zinc, nickel and uranium values from the Bullock property as well as the previously known gold occurrences (Minister of Mines Annual Report 1952).

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 Bullock occurrence included sample B2-3, a grab sample grading 140.16 grams per tonne gold, 69.8 grams per tonne silver, and greater than 1.0 percent lead, and sample B3-B2-13, a 0.80 by 0.80 metre panel grading 14.33 grams per tonne gold, and 0.14 percent arsenic (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.
