The Prosperity (L.1801) occurrence is reported to be located at an elevation of approximately 240 metres near the northwest bank of Hidden Valley Creek and approximately 2.9 kilometres north-northeast of the community of Zeballos.

The occurrence lies in the Zeballos gold camp, an area underlain by a Lower Jurassic Bonanza Group Island arc sequence of basaltic to rhyolitic volcanic rocks. Conformably underlying the Bonanza rocks are limestones and limy clastics of the Quatsino and Parson Bay formations, and the tholeiitic basalts of the Karmutsen Formation, all belonging to the Upper Triassic Vancouver Group. Dioritic to granodioritic Jurassic plutons of the Zeballos intrusion phase of the Island Plutonic Suite have intruded all older rocks. The Eocene Zeballos stock, a quartz diorite phase of the Catface Intrusions, is spatially related to the area's gold-quartz veins. Bedded rocks are predominantly northwest striking, southwest dipping, and anticlinally folded about a northwest axis.

Several narrow shear zones in andesitic tuffs occur on the Prosperity claims. Several open cuts were dug in the rusty, sheared rock but no mineralized quartz veins or sulphides were reported.

The Prosperity adit was driven from the east bank of Hidden Valley Creek and was an attempt to intersect rusty vein shears which strike east and dip 40 degrees north, higher up the hillside to the northeast. A vertical fault was intersected in the adit but no mineralization was encountered. Rocks within the adit consist of northwest striking lava and a 4.5 metre bed of limestone which strikes northwest and dips vertically.

Approximately 200 metres down Hidden Valley from this adit, traces of pyrrhotite and chalcopyrite were reported to be associated with a felsite dike (Assessment Report 5079). The dike strikes northwest and is thought to follow the contact between Lower Jurassic Bonanza Group andesites and crystalline limestone of the Upper Triassic Vancouver Group, Quatsino Formation.

Work History

In 1937, Zeballos Dome Gold Mines Ltd. staked the Prosperity (L. 1799 to 1805) claims. Several small opencuts and an adit are reported to have been developed by 1945. The adit has been driven for approximately 108 metres to the northwest.

In 1973 and 1974, Canadian Superior Exploration Ltd. completed programs of geological mapping and geochemical (rock and soil) sampling on the area as the Zeb group of claims. A sample (no. 15) volcanics with pyrrhotite and chalcopyrite from the mineralized dike exposed on the northwest side of Hidden Valley Creek, approximately 200 metres down valley from the adit, assayed 0.160 per cent copper and 1.200 grams per tonne gold (Assessment Report 5079).

In 2018 and 2019, 640895 BC Ltd. completed programs of rock, silt and soil sampling on the area as the Zeballos property.
