The Site 13 occurrence is located on a ridge separation between Sand and Hardscrabble creeks, approximately 2.5 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.

Locally, chalcopyrite, pyrite and molybdenite occur as open space fillings in highly fractured epidote-chlorite– altered andesite.

In 2002, a grab sample of augite andesite mineralized with pyrite and chalcopyrite as disseminations and fracture fillings returned 1.05 per cent copper, 90.5 parts per million silver, 318 parts per million zinc and 61 parts per million molybdenum (Assessment Report 27233).

In 2005, drillhole 05-01 intersected veinlets of massive pyrrhotite with blebs of chalcopyrite in the granodiorite at approximately 47 metres depth. Pyrrhotite, minor pyrite and rare chalcopyrite were also noted in the granodiorite in the form of pervasive disseminations (Assessment Report 28109).

In 2010, four samples (2930 through 2933) taken from Site 370, a zone of mineralized breccia located approximately 100 metres to the east, yielded values of 0.064 to 0.228 gram per tonne gold, 98.7 to greater than 100 grams per tonne silver, 67.0 to greater than 100 parts per million selenium and greater than 1.0 per cent copper (Assessment Report 32186).

In 2002, the Carlson group of mineral claims was staked by G.W. Kurz to cover a large area of pyrite mineralization. During 2003 through 2014, various programs of prospecting, geological mapping, a ground self-potential geophysical survey, two diamond drill holes, totalling 246.2 metres, and rock, soil and silt sampling were completed.
