The Sicker 1 occurrence is located on the northeastern slope of Mount Sicker, approximately 12 kilometres north-northwest of Duncan.
Regionally, the area is located within the Cowichan uplift and is underlain mainly by andesitic to rhyolitic volcanics of the Middle to Upper Devonian McLaughlin Ridge and Myra Formations (Sicker Group). The local stratigraphy is disrupted by folding, faulting (pre-Triassic as well as Paleogene–Neogene), intrusions of gabbro and diabase sills and dikes (known as the Mount Hall gabbro) that are coeval with the Upper Triassic Karmutsen Formation (Vancouver Group).
Locally, strongly chlorite-altered quartz-feldspar phyric rhyolite contains abundant chalcopyrite stringer mineralization. Immediately to the east, the altered rhyolite contains pods of massive magnetite up to 1 metre thick. These magnetite pods are flanked by zones of intense chlorite alteration and are cored by medium- to coarse-grained semi-massive pyrite.
Work History
Historical underground workings, likely dating to the early 1900s, are reported in the occurrence area.
During 1978 through 1980, S.E.R.E.M. Limited completed programs of geological mapping, ground geophysical surveys and soil sampling on the Rocky claims.
In 1982, a three-hole drill program, totaling 107 metres, was completed for Philip Liberman on the Sicker 1-2 and Geo 1-2 claims. Drillcore samples yielded values up to 0.34 gram per tonne gold, 8.6 grams per tonne silver and 0.1 per cent lead (Assessment Report 11841). The exact location of the drillholes is unknown.
In 1985 and 1986, Falconbridge Copper completed programs of geological mapping, rock sampling and an induced polarization survey on the Sicker and Rocky claims. Sample 2373 assayed 8.2 grams per tonne silver, with minor copper and zinc values (Assessment Report 13907).
In 1987, Minnova Inc. completed 16 diamond drill holes, totalling 3217.2 metres, on the Twin property. One hole (MTS33) was completed on the Sicker 1 claim but failed to intersect any significant mineralization, yielding a maximum of 0.35 per cent copper over 0.80 metre (37.60 to 38.40 metres down hole) from a chloritic, blocky zone in andesitic crystal tuff with pyrite and trace chalcopyrite (Assessment Report 16716). This drillhole was located approximately 1.15 kilometres to the south-southeast of the plotted location of the occurrence.
During 1988 through 1990, Minnova completed programs of geochemical sampling and at least eight diamond drill holes, totalling 3102.5 metres, on the Mount Sicker property.
In 2008, Westridge Resources completed a 440.3 line-kilometre airborne geophysical (magnetic and electromagnetic) survey on the area as part of the Fortuna property. In 2010, Westridge Resources conducted a program of geological mapping and rock sampling on the area as the Big Sicker Mountain property. Grab sampling of the occurrence area yielded values up to 1.59 per cent copper and 9.6 grams per tonne silver (sample C401259; Assessment Report 31677).
In 2014, Le Baron Prospecting conducted a program of prospecting and rock sampling on the area immediately south as the Mt. Sicker Copper property. A rock sample (Q029772) from an outcropping of graphitic schist hosting chalcopyrite, quartz and calcite, located near a logging road approximately 350 metres south of the plotted location of the Sicker 1 occurrence, yielded 16.20 per cent copper, 23.2 grams per tonne silver and 0.93 gram per tonne gold (Assessment Report 35408).
In 2019, Le Baron Prospecting conducted a further program of prospecting and rock sampling on the area immediately south as the Mt. Sicker Copper property.
In 2020, 911 Mining Co. conducted a program of prospecting and geochemical (rock and silt) sampling on the area as the Mount Sicker property. A chip sample (S-1) from a 0.5-metre wide and at least 12-metre long quartz vein hosting semi-massive pyrite with minor chalcopyrite and magnetite, located approximately 200 metres east of the Sicker 1 occurrence, assayed 0.67 per cent copper, 4.5 grams per tonne silver and 0.38 gram per tonne gold (Assessment Report 39405). Also at this time, a sample (S-70) from a 1.5-metre wide quartz vein with massive magnetite pods, pyrite and minor chalcopyrite hosted in limonitic schists, located approximately 250 metres north of the occurrence, yielded 1.34 per cent copper (Portable-XRF assays; Assessment Report 39405).
In 2021 and 2022, Scenc Resources Corp. completed a minor program of geological mapping, rock sampling, a 1.8 line-kilometre ground electromagnetic survey and four backpack drill holes, totalling 14.9 metres, on the Mount Sicker property. Three outcrop samples of schistose volcanics hosting 15 to 30 per cent magnetite, pyrite and chalcopyrite, taken from a road cut approximately 150 metres to the north of the occurrence, yielded from 0.16 to 1.25 per cent copper (Assessment Report 40298).
Later in 2022, Sasquatch Resources Corp. completed a program of prospecting, geological mapping, drillcore and rock sampling and a 418.2 line-kilometre airborne electromagnetic survey on the Mount Sicker property.
