Location and accuracy The Bartholf property, which apparently straddles the Alaska-British Columbia boundary, is mainly in British Columbia. It is in Sections 2 and 3 at an elevation of about 1430 feet, on the north side of a west-trending ridge about 0.6 mile north-northeast of Cantu Mountain (Elliott and Koch, 1981, p. 15, loc. 56).

Geologic setting

Geologic description

The country rock in the area of this occurrence is Triassic Texas Creek Granodiorite, which regionally underlies and locally intrudes pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group (Smith, 1977; Koch, 1996).
The deposit (Buddington, 1929, p. 92-93) consists of a quartz fissure vein, probably in granodiorite. The vein is as much as a foot thick (average is 6 inches thick) and contains disseminated chalcopyrite and local shoots of pyrite and galena; plates of barite are common.

Additional comments

Property originally staked in mid-1920s. Claims lie mainly on the Canadian side of the International Boundary.
