The stratigraphy in the Canyon 18 SB showing area is intruded by a Triassic quartz dioritic intrusion and a Triassic ultramaifc intrusion of the Polaris Ultramafic suite. The country rock is greenstone and sedimentary rock of the Upper Triassic Stuhini Group.

The showing consists of blebs and veins of stibnite in a brecciated quartz-diorite dike intruding mafic volcanics and granodiorite. The best mineralization is exposed in the creek bed at the toe of a glacier; it consists of stibnite in the interstices between breccia fragments and in quartz veinlets. The mineralization is limited to a few narrow sections of the dike; rock samples yielded only precious metal low values.

Work History

Previous work in the Grand Potter area was limited to mapping and rock sampling performed by Silver Standard Mmes in 1964. (Bik claims, Assessment Report 592).

In 1988 the Canyon 18, 19, 35, 36 and Gran 14 claims (South Scud property) were staked and later acquired by Homestake Mineral Development Co and Equity Silver Mines Ltd. Reconnaissance level exploration was performed by Homestake in 1989. Homestake prospected the property in 1989; reporting no significant results. 31 rock and 166 soils samples were collected. Work involved 1:10,000 scale mapping as well as the collection of 26 rock samples and 9 silt samples.

In 1990, Operator Yukon Minerals conducted reconnaissance traverses on the South Scud property located copper mineralization in a series of parallel quartz veins hosted by granite on the east side of the claim group. A 3.5 kilometre picket grid was established over the showing to facilitate mapping and soil geochemistry.
