The McVicar occurrences are located on the north side of Mount Baldwin, approximately 5 kilometres north west of Clarion Lake.

The area occurs on the eastern edge of the Britannia- Indian River pendant, which hosts the volcanogenic deposits of the Britannia camp (MINFILE 092GNW003). The Britannia-Indian River pendant is mainly a calc-alkaline, sub-aqueous volcanic and sedimentary sequence of felsic to intermediate pyroclastics, flows, cherts, argillites and greywackes. The entire pendant has been classified as part of the Upper Jurassic to Lower Cretaceous Gambier Group. Cenozoic to Mesozoic Coast Plutonic Complex intrusives surround portions of the stratified rocks, creating screens or pendants. These bodies are oriented north westerly throughout the Coast complex. Pliocene to recent Garibaldi Group basaltic dikes and sills intrude both the pendant and plutonic rocks.

The occurrences are underlain by a bimodal sequence of pyroclastic andesite volcanics with lesser andesite volcaniclastics and rhyolite of the Gambier Group in fault contact, at depth, with granodiorite of the Coast Plutonic Complex. This package has been intruded by felsic, intermediate and mafic Garibaldi Group dikes. The occurrence is located north of the Indian River shear zone, a discontinuous zone of shearing that trends northwest along the Indian River valley. A thick succession of andesite fine ash to lapilli ash tuff and feldspar crystalline andesite is intercalated with thin lenses of rhyolite, and underlies the main part of the McVicar zone. East of the zone, the volcanic succession is felsic in composition and dominated by rhyolite and dacite. The volcanic assemblage comprising the McVicar zone is a tilted sequence striking 160 degrees and dipping steeply to the west at 75 degrees. Lithologic contacts between the volcanic units are poorly exposed on surface. In drill core, a large percentage of the observed contacts are sheared, faulted or gradational, characterized by facies changes in andesite. A regional foliation striking 350 degrees and dipping 85 degrees east is imposed on the volcanic rocks. Quartz veining is dominantly localized in fracture planes oriented parallel to foliation. Abundant shearing is also evident along foliation accompanied by intense sericitization. The volcanic rocks in the McVicar zone contain up to 10 per cent pyrite as disseminations or as wisps and bands aligned parallel to foliation or shearing.

The McVicar zone is a north west- trending zone of strongly altered volcanic rocks with numerous surface showings of sulphide mineralization that defines a 1600 by 400 metre area. The zone is structurally complex with numerous faults transecting the stratigraphy. Examination of slicken-sides indicate that both normal and reverse movement occurs on the faults, the dominant being reverse dip-slip with a local strike-slip component. Garibaldi Group dikes are localized along fault zones.

Five alteration assemblages are recognized in the McVicar zone: (1) silicification, (2) sericitization, (3) hematization, (4) chloritization and (5) epidotization. Silicification is the most apparent and occurs as two types:, stockwork and pervasive. Stockwork silicification varies from intense to weak, and occurs as irregular quartz veinlets that are oriented sub-parallel to foliation. The veinlets are 1 to 20 millimetres wide but are locally up to 20 centimetres. Individual zones of stockwork silicification varies from less than 1 up to 24 metres in width. The margins of these zones are either gradational, exhibiting a progressive increase in the percentage of veins towards the centre of the zone, or sharp, with contacts parallel to the foliation. Jasper is uncommon, but occurs locally as veinlets associated with the margins of quartz veins.

Pervasive silicification is often associated with stockwork silicification. The intensity of pervasive silicification varies from weak, characterized by discolouration of andesitic volcanics, to strong, where it obliterates primary textures in andesite tuffs. The margins of these altered zones may be gradational over 10 to 20 centimetres with progressive increases in the intensity of silicification towards the centre of the zone, or sharp, with contacts terminated parallel to foliation. These two types of silicification are locally associated with distinct breccia zones up to 5 metres thick which strike northwest and dip west, parallel to the foliation of the McVicar zone.

Sericitization is the most common alteration but is less apparent than silicification. It is dominantly in the matrix of the volcanic rocks, but within the McVicar zone it forms discrete intense zones varying in width from less than 0.2 metre up to 3.3 metres. Locally, zones of sericitization are associated with moderate to strong shearing. Chloritization is weakly developed and is evident in the matrix of andesitic volcanics. Intensity varies from weak to strong. Patchy to pervasive hematization is associated with silicification. Zones of hematization are gradational, showing a progressive decrease in intensity towards the margins of the zones. Minor epidote alteration was noted in drill core as blebs in andesitic volcanics.

Extensive sulphide mineralization in the McVicar area has been exposed in numerous trenches and adits. Most of these occurrences are named after the claims (Crown grants) upon which they are located and include the Whistler (Lot 6160), south and north Harding (Lot 6152), Rainstorm (Lot 6153), Cabin Fraction (Lot 6158), Violet (Lot 6162), Ruth, Lily (Lot 6161)-Rose (Lot 6163), Grouse Fraction (Lot 6157), Noonday (Lot 6154) and Mamguam (Lot 6155).

The Whistler zone consists of a silicified cherty breccia within a dacite crystal tuff and interbedded dacite flows hosting massive sphalerite, chalcopyrite and galena mineralization occurring as northwest- trending, steeply east- dipping stringers, veins and pods that characteristically pinch and swell along strike. Stringers and veins may by localized in, or terminated by, shears and are associated with intense pervasive and/or stockwork silicification. A zonation, from sphalerite margins to chalcopyrite cores, is locally observed in the veins and stringers. Trenches are reported to have exposed mineralization over a distance of 45 metres. In 1978, a 1.3- metre sample from trench 3 assayed 3.48 per cent copper, 10.2 per cent lead, 15.65 per cent zinc, 95.64 grams per tonne silver and 0.34 gram per tonne gold, while a 12.1- metre sample from trench 2 assayed 13.7 grams per tonne silver, 4.5 per cent copper. 0.9 per cent lead and 4.2 per cent zinc (Assessment Report 7021).

In 1981, diamond drilling, located between the Whistler and South Harding zones, yielded intercepts of up to 0.192 per cent copper, 0.629 per cent zinc and 2.4 grams per tonne silver over 3.0 metres, while another 3.0- metre section assayed 0.920 per cent zinc (Hole BM-1-81; Assessment Report 10293). Another drill hole (BM-3-81) yielded intercepts up to 1.27 per cent zinc and 2.6 grams per tonne silver over 3.0 metres (Assessment Report 10293). In 1987, diamond drilling encountered mineralization beneath the Whistler showing with intercepts yielding up to 2.4 per cent copper, 1.86 per cent zinc, 1.94 per cent lead and 38 grams per tonne silver over a sample width of 0.3 metre (DDH BM87-2; Assessment Report 16494).

The South Harding zone, located approximately 250 metres north- north west of the Whistler zone, consists of massive lenses of pyrite, 0.2 to 0.3 metre wide, with parallel bans of chalcopyrite up to 0.1 metre wide. Veinlets and irregular patches of chalcopyrite occur adjacent to the lenses. Minor, 1 to 2- centimetre, jasper veins are cut by quartz-sphalerite veinlets. The mineralized zone is 2 to 5- metres wide and encompassed by a zone up to 40 metres wide of strong silicification and disseminated pyrite. Previous sampling of the zone is reported to have yielded up to 3.15 per cent copper and 20.5 grams per tonne silver over 3.6 metres from trench M15, while diamond drilling (Hole 3-2) yielded two mineralized intercepts yielding 2.8 and 1.5 per cent copper, 0.1 and 0.2 per cent lead and 0.3 and 1.8 per cent zinc with 41.0 and 37.6 grams per tonne silver over 3.0 and 4.6 metres, respectively (Assessment Report 11642).

The North Harding zone, located approximately 200 metres north- north east of the South Harding zone, consists of several areas of massive pyrite with minor chalcopyrite along a north- south shear hosted by altered pyritic schists. In 1947, a sample (M42) assayed 16.4 grams per tonne silver, 0.15 per cent lead, 2.6 per cent zinc and 1.05 per cent copper over 1.35 metres (Property File - Victor Dolmage (1953-05-15): McVicar Copper-Zinc Deposits, Raffuse Creek, Squamish, BC).

The Rainstorm (Copper) zone, located approximately 500 metre north- north west of the Harding zone, consists of moderately deformed stringers and lenses, up to 0.3 metres wide, of massive chalcopyrite that strike approximately 320 degrees and dip vertically. The stringers and lenses form a continuous network of mineralization over the length of a 12- metre outcrop, up to 1 metre wide, that parallels a fault contact between the host rhyolite and andesite lapilli ash tuff. Sulphide mineralization has been traced for a strike length of 90 metres. A mineralized fracture is reported nearby the main zone but strikes north-east with a vertical dip and hosts chalcopyrite with minor galena. In 1947, a 3.0- metre sample from a trench on the main mineralized fracture assayed 9.10 per cent copper and 51.3 grams per tonne silver, while a 1.2- metre sample (D1) from the second fracture assayed 47.9 grams per tonne silver, 1.1 per cent lead and 7.3 per cent zinc (Property File - Victor Dolmage (1953-05-15): McVicar Copper-Zinc Deposits, Raffuse Creek, Squamish, BC).

Another mineralized zone is reported on the Rainstorm Crown grant, approximately 260 metres north of the “Copper” zone. It consists of an intensely silicified shear zone hosting pyrite and chalcopyrite. In 1947, a sample (M22) assayed 10.3 grams per tonne silver and 0.35 per cent copper over 1.2 metres (Property File - Victor Dolmage (1953-05-15): McVicar Copper-Zinc Deposits, Raffuse Creek, Squamish, BC).

The Violet zone, located 150 metres south west of the Rainstorm zone, consists of chalcopyrite with lesser sphalerite and galena hosted by a quartz-chalcedony-jasperlite stockwork in a rhyodacite porphyry. In 1947, a sample (M55) assayed 54.7 grams per tonne silver and 6.3 per cent copper over 0.75 metre (Property File - Victor Dolmage (1953-05-15): McVicar Copper-Zinc Deposits, Raffuse Creek, Squamish, BC). In 1978, two select grab samples from trenches assayed 9.15 and 3.28 per cent copper, 2.16 and 13.45 per cent lead, 5.50 and 18.70 per cent zinc with 76.6 and 62.6 grams per tonne silver, respectively (Assessment Report 7021).

The Cabin Fraction zone, located approximately 500 metres north- north west of the Rainstorm zone, consists of semi-massive to disseminated pyrite with minor chalcopyrite and sphalerite hosted by a 80- metre wide zone of siliceous schist and/or andesite in a zone of shearing that trends north-south and dips 45 degrees to the west. In 1947, chip sample (M32) assayed 13.7 grams per tonne silver and 0.35 per cent copper over 2.1 metres (Property File - Victor Dolmage (1953-05-15): McVicar Copper-Zinc Deposits, Raffuse Creek, Squamish, BC).

The Noonday (Rock Creek) zone, located approximately 400 metres north of the Cabin Fraction zone, consists of a mineralized and silicified shear zone cutting greenstones and agglomerates. Mineralization consists of pyrite, chalcopyrite, sphalerite and galena. In 1947, a sample (M47) assayed 68.4 grams per tonne silver, 2.2 per cent lead, 11.8 per cent zinc and 0.8 per cent copper over 0.9 metre (Property File - Victor Dolmage (1953-05-15): McVicar Copper-Zinc Deposits, Raffuse Creek, Squamish, BC).

The Mamguam zone, located near the south east side of McVicar Creek near its junction with Rock Creek, consists of a 3.6 to 4.5- metre wide shear zone, striking north west and dipping steeply south west, hosting pyrite and chalcopyrite. In 1947, a sample (D2) assayed 13.7 grams per tonne silver and 2.5 per cent copper over 1.8 metres (Property File - Victor Dolmage (1953-05-15): McVicar Copper-Zinc Deposits, Raffuse Creek, Squamish, BC).

The Lily-Rose zone, located approximately 270 metres east of the Whistler zone, consists of several trenches and open cuts exposing discontinuous pyrite and chalcopyrite veins in a quartz stockwork over a zone 4.5 to 5.4 metres wide. In 1947, sampling of the Lily zone yielded up to 68.4 grams per tonne silver, 2.6 per cent lead, 1.1 per cent zinc and 5.2 per cent copper over 4.5 metres; while the Rose zone yielded up to 136.8 grams per tonne silver and 12.5 per cent copper over 0.6 metre (Property File - Victor Dolmage (1953-05-15): McVicar Copper-Zinc Deposits, Raffuse Creek, Squamish, BC).

The Grouse Fraction (Lead) zone, located just south of the Lily-Rose zone, consists of a flat- lying zone of massive galena with minor chalcopyrite associated with an anastomosing stockwork of quartz-chalcedony veins in a local zone of brecciation. In 1978, two samples taken across two parallel veins, 0.5 and 0.4 metres wide, assayed 5.7 and 1.4 per cent copper, 47 and 22 per cent lead and 3 and 6 per cent zinc with 44.5 grams per tonne silver, respectively (Assessment Report 7021). Previous drilling on the zone is reported to have yielded up to 1.34 per cent copper over 1.34 metres in hole 71-4 and 0.32 per cent copper, 12.57 per cent lead and 1.22 per cent zinc over 1.6 metres in hole 71-5 (Assessment Report 11642).

The Ruth zone, located approximately 150 metres north east of the Whistler zone, consists of a 15- centimetre wide vein of sphalerite, pyrite, chalcopyrite and galena hosted by a siliceous breccia with large fragments of green rhyodacite porphyry in a quartz matrix. The vein cuts across the north- north west trend of the breccia unit. The vein terminates, to the east, against a north- trending basaltic dike.

Previous drilling, in 1928, outlined an indicated reserve of 119 ,737 tonnes of ore grading 2 per cent copper with minor amounts of lead, zinc and silver underlying the Rainstorm and North Harding showings (Assessment Report 16494; Northern Miner - April 30, 1964).

More recent diamond drilling, in 1987, revealed that discontinuous, low- grade sulphide mineralization is localized in quartz veining oriented parallel to foliation in the McVicar zone. A large percentage of sulphide mineralization in the zone occurs as stringers and disseminations associated with, and hosted by, stockwork silicification. However, spectacular sulphide mineralization occurs as lenses and stringers, aligned parallel to foliation, at the Whistler and Rainstorm showings. The McVicar zone mineralization is postulated to represent a low-grade volcanogenic sulphide system with remobilized sulphides in higher grade stringer zones.

The McVicar occurrence was discovered in 1923, and in 1925 and 1928, Brittania Mining and Smelting performed programs of diamond drilling, totalling 1050 metres in nine holes, on the area. In 1946, Western Surf Inlet acquired the property and performed programs of diamond drilling on the Rainstorm, Harding and Whistler zones during 1953 and 1954. In 1962, the Western Surf Inlet Mines completed a program of soil sampling, geological mapping and a ground electromagnetic survey on the area as the Bob and Phil claims. In 1964, Anaconda American Brass took soil samples from the area. During late 1969 and early 1970, Kennedy Silver Mines completed a program of soil sampling and geological mapping on the area immediately south as the Dal, Lilly and Agape claims. This work identified a south east- trending area of anomalous copper and zinc values in soils. Later in 1970, Croyden Mines completed a program of diamond drilling, totalling 1221.6 metres in an unknown number of holes, and a ground electromagnetic survey on the area. During 1978 through 1983, Texasgulf and later Kidd Creek Mines completed programs of rock and soil sampling, geological mapping, ground and airborne geophysical surveys and three diamond drill holes, totalling 855.5 metres. In 1987, Kidd Creek Mines completed a program of rock sampling, geological mapping and nine diamond drill holes, totalling 2796.0 metres. During 2011 through 2016, the area was prospected and sampled as the Sky Pilot Gold property.
