Capsule Geology

The Alice Group (Clancy) occurrence is located at the north end of Victoria Lake and west of Alice Lake in the northern part of Vancouver Island, Nanaimo Mining Division of BC. The physiography of the area is moderately rugged and elevations on the claim group ranges from 100 to 800 metres.

The area is underlain by the Upper Triassic Vancouver Group, Quatsino Formation limestones which have been intruded by granodiorite related to the Late to Middle Jurassic Island Plutonic Suite.

The Clancy occurrence is considered to be a limestone replacement-type deposit (Gunning, Geological Survey of Canada Summary Report 1929); although in Assessment Report 10865 it is referred to as a fissure-filling.

Mineralization is located in white to grey limestone, which is cut by un-mineralized dikes comprised of felsite to diorite that are related to a Jurassic intrusive stock exposed 1.0 kilometre south. The limestone is northwest striking and gently folded, with low angle east and west dips.

The bedded limestone replacement mineralization ranges from 5 centimetres to 1.2 metres wide. Mineralization consists of complete replacement to disseminations of sphalerite (plus or minus chalcopyrite), galena (plus or minus tetrahedrite), pyrite and arsenopyrite.

A sample taken in 1929 assayed 13.7 grams per tonne gold, 342.9 grams per tonne silver, 12 per cent lead and 8.0 per cent zinc (Geological Survey of Canada Summary Report 1929a, p. 137). Underground diamond drilling in 1982 averaged over a 4.9-metre interval 13.6 grams per tonne gold, 143.3 grams per tonne silver, 7.87 per cent lead and 7.54 per cent zinc (Northwest Prospector 1982).

Work History

Initial property evaluation work by Ekaty Geological Ltd. included visits to the property by two geologists in August and November 1988. Known mineralization was sampled during these visits and its geochemical signature was established by base and precious metal analysis. A total of five massive sulphide rock samples were collected in August and assayed for copper, lead, zinc, silver and gold. Sampling of the Clancy adit yielded up to 13.9 grams per tonne gold and 160.5 grams per tonne silver (Assessment Report 18812).

In 1989, further examination of the property was carried out by two geologists and included three small geochemical surveys over areas of the Alice Group. A total of 115 soil samples and eight rock samples were collected. Soil samples were taken from 20 centimetres depth.

In April 1990, the property was visited by one geologist and additional geochemical sampling was completed over two of the previously established grid areas. A total of 35 samples were collected on a grid that covers the AJ #4Fr, AJX #12Fr, ALM #13 and ALM #15 claims. The grid lines extended from an abandoned logging road to the area of a magnetometer anomaly identified in 1969 by Seigel and Associates. The Olga grid returned the most anomalous results, particularly in silver, where values up to 8.3 grams per tonne were returned (Assessment Report 20138).

During 2017 through 2019, Harco Holdings Ltd. completed minor programs of prospecting, geological mapping and rock sampling on the area as the Pilgrim property. In 2017, two samples (J488621 and J488622) from the Clancy zone yielded an average 8.33 per cent zinc, 0.29 per cent copper, 158 grams per tonne silver and 22.8 grams per tonne gold (Assessment Report 37127).
