The Wolf prospect is located near the southern margin of the Klastline Plateau within an Early Jurassic intrusion known as the Groat Stock (Open File 1997-03).
Nuspar Resources Ltd. (formerly Spartan Explorations Ltd.) prospected the Wolf claims in 1974. A.C. Racicot did some minor trenching on the occurrence (held as the Goat claim) in 1976. Texasgulf followed up in 1977 with 17 metres of trenching on the Noodle claims. The Axe claims were staked in 1988, covering the Wolf ground, and were acquired by Ascot Resources Ltd. in 1989. The Axe property consisted of some 59 claims totalling 932 units. Work done on the Axe claims in 1990 and 1991 (primarily rock, soil and silt sampling) was spread over several showings on these extensive holdings. An induced polarization geophysical survey was conducted on the Wolf showing in 1991.
Most of the Groat stock and area was mapped as part of a 3-year regional mapping survey (1994 to 1995) headed by Chris Ash of the provincial Geological Survey Branch.
The Early Jurassic Groat stock intrudes a sedimentary unit of the Upper Triassic Stuhini Group consisting of volcanic sandstone, silstone, mudstone, and lesser siliceous mudstone and chert. The Groat stock is a faulted, northeast trending, coarse-grained porphyritic to fine-grained equigranular intrusion with granodiorite to quartz monzonite modal compositions. A Uranium-Lead age date of 205.1 plus/minus 8 Ma was determined by R.M. Friedman of the University of British Columbia (Fieldwork 1996, page 295).
Property rocks were described in 1991 as cherty siliceous mafic ash tuffs intruded by a leucocratic hornblende diorite plug. Some argillaceous sediments are interbedded with the tuffs in the Wolf area. A swarm of east trending, steeply dipping augite diorite dikes and a north trending set of felsite dikes are reported to cut the intrusive rocks.
The Wolf showing was described in the 1970s as chalcopyrite with malachite, azurite and pyrite occurring as disseminations in fractured diorite and as steeply dipping massive veinlets up to 15 centimetres wide, paralleling felsite dikes. The zone of disseminated copper mineralization extended with variation in grade for over 100 metres, with an inferred width of 60 metres and a vertical interval of 50 metres. A trench sample taken in 1977 contained a high of 0.13 per cent copper and 0.07 gram per tonne gold (Assessment Report 6541).
The Pup showing, located approximately 400 metres to the southeast of the Wolf, consists of a gold geochemical anomaly in an area underlain by microdiorite. A chip sample from this area assayed 23.9 grams per tonne gold across 0.5 metre (Assessment Report 21858, page 17). This mineralization occurs near a 10 centimetres wide shear.
In 1991, a gold soil geochemical anomaly measuring 1 kilometre long by 100 to 200 metres wide was reported to occur within the main diorite stock. The trend of the anomaly is reported to be marked by numerous small north-south trending gossan structures which are weakly mineralized, the largest known as the Wolf showing. Continuous chip samples yielded 0.3 per cent copper and 0.1 gram per tonne gold across 10.85 metres (Assessment Report 21858, page 17). Barite also occurs as north trending striking veinlets in the diorite.
In 2010, Teck Resources Ltd. optioned the ground and the following year a program of geological mapping, geochemical sampling, geophysical surveys, and drilling of 3,356.5 metres in eight holes were completed on Wolf Plateau (upper) soil chargeability anomaly by Teck. Five northwest trending IP lines identified a chargeability anomaly within the sedimentary rocks at the contact with diorite (2011 Teck drillhole GJK-11-220), one of three on the Wolf zone, yielded a 6.95-metre interval that assayed 0.30 per cent copper and 0.29 gram per tonne gold (Table 6, Assessment Report 33085).
In 2012, Teck continued drilling with five holes, totalling 2613 metres, on the Wolf occurrence. Other work included ground and airborne geophysical surveys, soil and rock sampling and geological mapping. A drill hole (GJK-12-232) yielded 0.34 per cent copper and 1.72 grams per tonne gold over 7.6 metres, including 1.146 per cent copper, 7.48 grams per tonne gold and 10.3 grams per tonne silver over 1.5 metres of strong carbonate alteration (Giroux, G.H., Peatfield, G.R., Cathro, M.S. (2016-02-24): Technical Report on the Donnelly-GJ Deposit Area, GJ Property).
In 2016, Skeena Resources personnel spent six man-days evaluating and prospecting the Wolf (104G 045), Blowdown (104G 171) and Wolf West (104B 172) targets with two man-days spent on each. A total of 28 rock samples were collected from the targets. Sample descriptions with locations were recorded in Assessment Report 36505). An examination of the eastern and lower portions of the showing show typical porphyry style alteration and classic “B” type veins (with centreline chalcopyrite).
