Capsule Geology

The Silver Reef NW occurrence is located at an elevation of approximately 1510 metres on a northwest-facing slope, approximately 3.5 kilometres northeast of Sicintine Lake.

The area is underlain by black graphitic shales, wackes, grits and minor conglomerates of the Upper Jurassic to Lower Cretaceous Bowser Lake Group and Lower Cretaceous Skeena Group, that have been intruded by granodioritic rocks of the Late Cretaceous Bulkley Plutonic Suite.

Locally, a polymetallic vein system is hosted in a graphitic shale fault zone traced for approximately 650 metres along strike, trending 130 to 140 degrees and dipping 45 to 65 degrees to the southwest. The fault zone is pyritic and hornfelsed with clay gouge. The polymetallic veins, up to 0.15 metre wide, comprise quartz-carbonate veins and quartz veins, stockworks and silicification in a zone varying from 30 to 120 metres in width. Mineralization includes pyrite and arsenopyrite with variable amounts of sphalerite, galena, chalcopyrite, stibnite and sulphosalts. The zone is reported to be open along strike in both directions.

The fault structure(s) is associated with nearby felsic Bulkley dikes with parallel strikes, dips 40 to 45 degrees to the southwest, and lies within the hornfelsed aureole of the Bulkley Intrusion.

In 2018, rock samples (#13 and #14) of weathered ferrocrete and veins assayed up to 0.97 gram per tonne gold, 65 grams per tonne silver and 0.19 per cent lead (Tuck, A. [2020-09-20]: NI 43-101 Technical Report on the Silver Reef Property, Omineca Mining Division, British Columbia, Canada).

In 2020, drilling on the Northwest zone yielded up to 0.23 gram per tonne gold, 30.71 grams per tonne silver, 0.47 per cent lead and 1.04 per cent zinc over 6.72 metres (27.00 to 33.72 metres down hole) in hole SR-010, whereas rock samples (749600 and 749601) from the zone yielded up to 2.65 grams per tonne gold, 245 grams per tonne silver, 3.1 per cent lead, 0.18 per cent zinc and 1.00 per cent antimony (Tuck, A. [2020-09-20]: NI 43-101 Technical Report on the Silver Reef Property, Omineca Mining Division, British Columbia, Canada; and Assessment Report 39422).

Work History

In 2018 and 2019, Rick Kasum completed programs of prospecting, geological mapping, rock sampling and eight shallow packsack drill holes, each 0.6 to 1.2 metres long, on the area.

In 2020, P2 Gold Inc. completed a program of prospecting, geological mapping, rock sampling, a 1296 line-km airborne magnetic and radiometric survey, and 14 diamond drill holes, totalling 1689 metres, on the Silver Reef property (Assessment Report 39422). Also see MINFILE 093M 228.
