The Hazel 7 occurrence is located on a ridge south of Kinsman Creek, approximately 5.5 kilometres south east of the creek mouth on Nimpkish Lake. Several nearby occurrences have similar geological settings, including the East Hazel (092L 206) and Kinman-Nimpkish Copper (092L 036).

North striking carbonates and calcareous sediments of the Quatsino and Parson Bay formations overlie Karmutsen Formation tholeiitic basalts, all of the Upper Triassic Vancouver Group. Lower Jurassic Bonanza Group andesitic to rhyodacitic lava, tuff, breccia and minor sediments are coeval with, or genetically related to, granodiorite of the Nimpkish batholith of the Jurassic Island Plutonic Suite. Strong regional north to northwest trending faults, often defining intrusive and lithological contacts, traverse the area.

Mineralization occurs at the contact between granodiorite and Quatsino Formation limestone. Here, an intrusive sill, 30 metres wide, projects about 100 metres into the sediments from the main intrusion.

The mineralization measuring 23 metres wide by 14 metres high and 4 metres thick, cuts across bedding that strikes 080 degrees and dips 50 degrees north. The lens gently dips north. Mineralization consists of massive chalcopyrite and sphalerite with minor pyrite in a gangue of garnet, epidote and local calcite replacing limestone.

One trench encountered "altered feldspar porphyry and altered granodiorite" (Geological Survey of Canada Memoir 272, page 73). No details are given.

Diamond drilling at the occurrence encountered mineralization up to 1.77 per cent copper over 38 centimetres and 0.83 per cent copper over 1.2 metres (Geological Survey of Canada Op. Cit.).

The Minister of Mines Annual Report for 1929 gives an estimate of 20 per cent copper over 4.5 metres in an unspecified trench (Minister of Mines Annual Report 1929, page C381).

In 1989, a sample of massive chalcopyrite with disseminated sphalerite in a manto pod from the open pit assayed 283 grams per tonne silver, 0.19 grams per tonne gold, 0.116 per cent cadmium, 21.95 per cent copper, 0.405 per cent lead and 15.2 per cent zinc (Assessment Report 20092). In 2010, a representative sample of the main metal zone assayed 9.23 per cent copper, 27.84 per cent zinc and 97.5 grams per tonne silver (Assessment Report 31717). In 2012, rock chip samples averaging 1 metre in length and 8.3 kilograms in weight yielded an average value of 8.26 per cent copper, 13.2 per cent zinc and 99.7 grams per tonne silver (Assessment Report 33632).

The mineralized lens is estimated to contain 2700 tonnes (Assessment Report 831, page 11).

In 1928, E.L. Kinman and Associates discovered the main showings. In 1929 and 1930, Cominco optioned the tenures and completed surface trenching and twenty diamond drill holes, totalling 2010 metres on the area. In 1962, Camloc Copper completed a program of geological mapping and a 0.7 kilometre magnetometer survey on the area as the Hazel Group. In 1966, Empire Development completed a program of ground geophysical surveys and geological mapping on the area as the Alpha, Hazel and Pie claims, Kinman property. In 1989, W.J. Laird completed a program of rock sampling and geological mapping on the area to the west as the Nimpkish claims. In 1998 and 1999, Doublestar Resources completed programs of prospecting and ground geophysical surveys on the area as the 2Star claim group. In 2010 and 2012, Selkirk Metals completed programs of prospecting and rock sampling.
