The Site 155 occurrence is located on a ridge to the north of Hardscrabble Creek, approximately 2.3 kilometres west of the Skeena River.

The area is underlain by a sequence of volcanic and sedimentary rocks that have been mapped as Early Jurassic Hazelton Group or more recently as Early Jurassic Kitselas volcanics. The Kitselas volcanics are predominantly of felsic composition. These have been intruded by granites, granodiorites and diorites of the Eocene Carpenter Creek pluton.

Locally, a zone of chalcopyrite and pyrite mineralization is reported.

In 2010, two rocks samples (2941 and 2942) assayed 0.084 and 0.125 gram per tonne gold, 0.334 and 0.976 per cent copper and 44.6 and 9.8 parts per million tellerium with 89.1 and greater than 100 grams per tonne silver, respectively (Assessment Report 32186).

In 2002, the Carlson group of mineral claims was staked by G.W. Kurz. During 2003 through 2014, various programs of bedrock prospecting, rock chip sampling, geological mapping, a ground self-potential geophysical survey and geochemical soil and silt sampling were completed.
