The Hardscrabble showing is located on the north side of the Hardscrabble Creek logging road, approximately 1 kilometre west of the Grotto vein (MINFILE 103I 045) in the canyon of Hardscrabble Creek.

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 quartz-scheelite veining outcrops with small, visible sulphide grains (sphalerite and galena) occurring in a silicified zone associated with aplite dikes. The dike and vein system strikes roughly east, sub-parallel to the road; it shortly disappears under cover in both directions.

In 2005, two samples were assayed. Sample EK08-1 is described as a 20 centimetre quartz vein in silicified aplite with pyrite, chalcopyrite, chalcocite, bornite and galena and assayed 30.234 grams per tonne gold, 0.104 per cent lead and 0.037 per cent zinc. Sample EK08-1a assayed 253 grams per tonne gold, 0.41 per cent lead and 0.314 per cent zinc (Fieldwork 2005, page 131, Table 2.).

In 2010, four rock samples (2917, 2918, 2919 and 2948) from the zone yielded up to 0.111 gram per tonne gold, 0.024 per cent molybdenum, 0.476 per cent copper, 0.679 per cent lead, 0.652 per cent zinc, 0.023 per cent cadmium, 0.053 per cent bismuth, greater than 0.01 per cent tungsten and greater than 100 grams per tonne silver (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.
