The 400M occurrence is located at an elevation of approximately 550 metres on the western slope of Mount Sicker. The past-producing Lenora mine (MINFILE 092B 001) is located approximately 600 metres to the southwest.

Regionally, the area is located within the Cowichan uplift and is underlain 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, an approximately 400-metre-wide zone of schists and/or schistose volcanics host quartz-pyrite stringer veins with minor chalcopyrite. The veins are up to 0.35 metre wide.

Work History

The area has been historically explored in conjunction with the nearby Lenora (MINFILE 092B 001) past-producer, and a complete early history of the Mount Sicker area can be found there.

In 2020, 911 Mining Co. conducted a program of prospecting and geochemical (rock and silt) sampling on the area as the Mount Sicker property. Three chip samples (S59 to S61) yielded from 1.19 to 21.43 per cent copper, 0.01 to 0.19 per cent zinc and 0.01 to 0.70 per cent lead (Portable-XRF assay; 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 yielded from 0.01 to 1.95 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. A select outcrop sample from a 0.3-metre wide quartz vein hosting chalcopyrite assayed 1.61 per cent copper, 9.5 grams per tonne silver and 0.12 gram per tonne gold (Assessment Report 41178).
