The Sku showing is located at an elevation of approximately 1360 metres on a north facing slope, south of Skuhun Creek and approximately 1.5 kilometres northwest of the north end of Farr Lake.
The area is situated along the southern margin of the central core of the multistage Upper Triassic to Lower Jurassic Guichon Creek batholith and is underlain by four distinct phases of the batholith, the contacts between which are on the property. Around Farr Lake, outcrops consist mainly of Chataway variety fine-grained granodiorite of the Highland Valley phase. To the northeast, the property is underlain by Bethlehem phase medium-grained granodiorite, tonalite and quartz diorite. These two phases are separated by a zone of rocks which are texturally and compositionally transitional between the two. Farther to the north, near Skuhun Creek, the older phases are intruded by the central Bethsaida phase of the batholith. This unit is coarse-grained quartz monzonite to granodiorite. Pink porphyritic monzonite occurs as a small dike-like body intruding the Bethsaida rocks at Skuhun Creek. It is believed to be related to north trending, salmon-pink aplite dike swarms, which intrude both the Bethlehem and Bethsaida phases. All of the intrusive phases are weakly to moderately propylitized, with biotite and hornblende altered to chlorite and epidote.
The structural features of the area are the east trending Skuhun Creek fault, several northeast and northwest trending lineaments and numerous fractures averaging four per metre. Associated with fracturing are 1 to 20 millimetre wide quartz veins containing fine-grained disseminated magnetite and specular hematite. Weak to moderate propylitization, sericitization, kaolinization and oxidation (limonite, malachite) are evident throughout the property. Intense hydrothermal alteration is limited to fault and shear zones in which clay gouges up to 2 metres in width consist of extensive sericite, clay, chlorite epidote and carbonate.
Mineralization consists of widespread disseminated magnetite, specular hematite, chalcopyrite and bornite in quartz veins and as fine-grained clusters in fractures, and malachite as coatings on fractures and in fault gouges.
In 1982, drill hole no. 1 yielded 0.184 per cent copper over 10 metres of strongly altered medium-grained granodiorite (Assessment Report 10553).
Work History
In 1968, the Northwest Syndicate completed a program of geological mapping and an induced polarization survey on the Skuhun Creek valley area as the Spa, Sku, Alta, Scat, Jeff and Lark claims. In 1969, Mercury Explorations Ltd. completed a 27.0 line-kilometre induced polarization survey on the area as the Sku claims. Also at this time, Tyner Lake Mines completed a 268.3 line-kilometre magnetometer survey and a 122.0 line-kilometre induced polarization survey on the area and Cyprus Exploration Corp. Ltd. completed a 4.5 line-kilometre induced polarization survey on the area immediately west of the occurrence as the KU claims.
In 1975, Cities Services Mining completed three rotary drill holes, totalling 258.0 metres, on the area immediately west of the occurrence as the Burn property.
In 1980 and 1981, Pearl Resources completed a program of geological mapping and 16 shallow percussion drill holes on the area. No significant intercepts were reported. In 1982, SMD Mining Co. Ltd. completed seven diamond drill holes, totalling 677.6 metres, on the Sku 1 and 2 claims.
In 2006, Gary Brown completed a program of prospecting and photo-geological interpretation on the area as the Chat and Skuhun claims of the Copper Hill property.
During 2009 through 2011, the area was examined by Highbank Resources Ltd. and Moag Copper-Gold Resources Inc. as the Highland Valley property. Programs of geological mapping, soil sampling and an induced polarization survey were completed during this time.
During 2012 through 2019, Happy Creek Minerals Ltd. completed programs of geological mapping, geochemical (rock, silt and soil) sampling, a 32.3 line-kilometre induced polarization survey and re-interpretating historical airborne geophysical data on the area as apart of the Rateria-West Valley property.
