The AM 1 showing is located 1200 metres west of American Creek and about 1800 metres north-northwest of the north end of Kimball Lake.

The west side of American Creek is underlain by Hazelton Group rocks in the north trending, faulted core of the American Creek anticline (Bulletin 63). Lowermost black argillites and overlying siltstones of the Lower Jurassic Unuk River Formation are overlain by green and maroon fragmental volcanics of the Lower Jurassic Betty Creek Formation. A major north-trending fault is oblique to the fold axis; axial planar faults or shears are parallel to the fold axial plane. Later east-trending faults strike across the fold-fault zone.

The showing consists of mineralized limestone fragments(?), a few to several metres across, in the maroon to green fragmental volcanic unit. The fragments are mineralized with disseminated galena, sphalerite and tetrahedrite(?). Chip sampling in 1986 assayed up to 0.55 gram per tonne gold, 547.2 grams per tonne silver, 0.06 per cent copper, 3.06 per cent lead and 7.58 per cent zinc across 1.25 metres (Assessment Report 15365).

Exploration has been conducted intermittently in the area since 1938. In 1979, Tournigan Mining Explorations Ltd. performed sampling on the Liliane claim (104A 112). During 1986-88, Square Gold Explorations (later renamed Glacier Resources and then Golden Glacier Resources) carried out geological mapping, sampling and drilling on the AM 1 claim. The drilling was done on the Bugnello prospect (104A 112). The showing was discovered in 1986.
