The Silver Reef occurrence is located at an elevation of approximately 1600 metres on an east-facing slope, approximately 3 kilometres east-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 2000 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 comprise quartz-carbonate veins, up to 20 metres in width, and quartz veins, stockworks and silicification up to 100 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 to the northwest and southeast.
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, a subcrop sample (no. 9) of a massive sulphide vein assayed 1892 grams per tonne silver, 2.01 grams per tonne gold, 4.46 per cent lead and 2.7 per cent zinc, whereas three other samples (no. 7, S022282 and S022280), taken a short distance south of the previous sample, yielded up to 3.33 grams per tonne gold and 47 grams per tonne silver (Assessment Report 38138). These samples were taken from the southern portion of the mineralized zone. Two samples (no. P4 and no. 3) of vuggy quartz vein outcrops, taken from the central portion of the mineralized zone, yielded 2.87 and 0.63 grams per tonne gold with 141 and 246 grams per tonne silver, whereas a 7.90-metre chip sample from the northern portion of the zone yielded 1.65 grams per tonne gold and 40 grams per tonne silver (Assessment Report 38138).
In 2019, samples from six shallow packsack drill holes, located on the central portion of the mineralized zone, yielded values from 0.11 to 0.42 gram per tonne gold, 56.4 to 322.0 grams per tonne silver and 0.023 to 0.485 per cent lead, whereas two surface outcrop chip samples (SR-19RK-01 and -02), 1.5 to 2.0 metres in length, from the area of the drillholes yielded from 0.30 to 0.71 gram per tonne gold, 120.0 to 147.0 grams per tonne silver and 0.218 to 0.231 per cent lead (Assessment Report 39134).
In 2020, drilling on the Main zone yielded up to 0.20 grams per tonne gold, 34.5 grams per tonne silver and 0.36 per cent lead over 10.55 metres (31.27 to 41.82 metres down hole), including 0.93 gram per tonne gold, 245.25 grams per tonne silver, 0.33 per cent lead and 0.98 per cent zinc over 1.3 metres in hole SR-004, whereas a rock sample (749602) from a 0.40-metre-wide mineralized and brecciated quartz vein assayed 918 grams per tonne silver, 0.32 gram per tonne gold, 22.5 per cent lead and 6.4 per cent zinc (Tuck, A. [2020-09-20]: NI 43-101 Technical Report on the Silver Reef Property, Omineca Mining Division, British Columbia, Canada).
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 094D 210.
