The Cam-Doc (Lucky Jim) occurrence is located on the east side of the Adam River, approximately 3.0 kilometres southwest of the west end of Tlowils Lake.
The area is underlain by Upper Triassic Quatsino Formation (Vancouver Group) limestone, which overlies Upper Triassic (Vancouver Group) Karmutsen Formation andesitic flows and tuffs. The limestone is intruded by a dacite porphyry dike that is chlorite altered and heavily oxidized. Weak bleaching of the limestone occurs up to 1 metre from the dike.
Locally, skarn-like siliceous replacement zones of limestone adjacent to the contact with a pyritic-dacitic feldspar-porphyry dike is mineralized with pyrite, pyrrhotite, chalcopyrite, lesser sphalerite, and rare galena. The sulphides occur as massive pods and stockwork-like networks of fracture fillings and disseminations.
1.) The River Level/Main zone strikes 350 degrees and dips 80 degrees west. It has been traced for 57 metres with an average width of 2 metres and was explored by two short adits before the 1950's. One adit follows the footwall for about 5 metres, the other (shorter) adit crosscuts the 2- to 2.5-metre-wide zone. The zone averages 5 per cent pyrite, 0.5 to 2.5 per cent chalcopyrite and variable amounts of pyrrhotite. In 1979, four chip samples taken over a width of 2.3 metres from the main zone averaged 1.27 per cent copper, 17.77 grams per tonne silver and 11.85 grams per tonne gold (Assessment Report 8190). In 1988, grab samples assayed from 0.27 to 11.2 grams per tonne gold (Assessment Report 17449, page 10). Later the same year, an average grade of the zone was reported as 7.55 grams per tonne gold, 34.3 grams per tonne silver and 2 per cent copper across an average width of 2.1 metres (Assessment Report 17755).
2.) The Plateau Level zone has been traced intermittently for 30 metres and is 0.45 to 1 metre wide. This zone averages 10 per cent pyrite with minor chalcopyrite. In 1987, grab sampling yielded values ranging from 0.27 to 9.5 grams per tonne gold (Assessment Report 17449, page 10).
Work History
The area has been explored in conjunction with the Cam – Doc West (MINFILE 092L 402) occurrence.
In 1919, Cominco completed a program of surface trenching and 21 metres of drifting on the area. In 1926 and 1927, six diamond drill holes were completed. In 1971, Western Standard Silver Mines completed a program of geological mapping and soil sampling and the area as the M 1-37 claims. In 1979, B. Taylor completed a program of geological mapping, rock sampling and a ground magnetometer survey on the area as the Dik and Dok claims. In 1980, Five M Resources completed a program of soil sampling, geological mapping, a magnetometer survey, and five diamond drill holes, totalling 450 metres of BQ wire line core. In 1988, Stetson Resources completed a program of rock - and silt sampling on the area as the Dave claims. Later the same year, Welcome North Mines prospected the area. In 2004, Hillsborough Resources completed a program of geological mapping and channel sampling on the area as the Jake 1-12 claims.
During 2018 through 2020, Altum Resource Corp. completed programs of prospecting, geological mapping, geochemical (rock and soil) sampling, a 3.5 line-kilometre induced polarization survey and a 361.0 line-kilometre airborne magnetometer survey on the area as the Adam West property. In 2019, seven grab samples from the Lucky Jim occurrence area yielded from 0.27 grams per tonne gold with 0.11 per cent copper to 24.9 grams per tonne gold with 5.31 per cent copper, while sample 19013 returned 5.62 grams per tonne gold, 79.3 grams per tonne silver and 4.79 per cent copper. (Wasteneys, H. [2019-07-25]: NI 43-101 Technical Report on the Adam West Property, Northern Vancouver Island, British Columbia). In 2020, a rock sample (27455) from a sheared contact of limestone and basalt hosting pyrite veins and disseminations assayed 1.545 per cent copper and 16.55 grams per tonne gold (Assessment Report 39283).
