The DWG Copper occurrence straddles McConnell Creek and is located approximately 3 kilometres downstream of the lowermost McConnell lakes, approximately 162 kilometres north-northwest of the community of Germansen Landing.
The regional geology is similar to that of the Gerle Gold deposit (MINFILE 094D 006) located 3.4 kilometres north-northeast.
Locally, the area is underlain by sheared granodiorite and quartz gabbro of the Lower Jurassic Fleet Peak pluton (Geology, Exploration and Mining in British Columbia 1973). The granodiorite is generally schistose and is composed predominantly of zoned, subhedral plagioclase crystals (2 to 4 millimetres in diameter) quartz and orthoclase. The quartz gabbro is composed of (in decreasing order of abundance): plagioclase, hornblende, quartz and orthoclase. The gabbro contains minor pyrite and exhibits epidotization near pegmatite and aplite dikes. Fracturing mainly strikes 160 degrees and dips 60 degrees northeast (Geology, Exploration and Mining in British Columbia 1973). Several sets of cross joints are weakly developed and these host most of the mineralization.
Five sulphide showings are exposed within a radius of approximately 200 metres. Showing A (or Zone A) is the only showing found on the east side of McConnell Creek; the other four occur on the west side. All the showings are quartz vein and fracture related and the most significant is the B showing.
Zone B or showing B is a quartz vein hosting chalcopyrite and pyrite. The vein is traceable for 15 metres and has a variable strike and thickness. The southwest extremity of the vein strikes 068 degrees, dips 65 degrees northeast and is approximately 3.7 metres in thickness. The strike changes to 062 degrees at the northeast end and the vein widens to approximately 4.6 metres.
In 1967, a chip sample (no. 1) is reported to have yielded 8.24 per cent copper, 116.3 grams per tonne silver and 0.7 gram per tonne gold over 0.38 metre (Richardson, P.W. (2007-08-30): Technical Report - The McConnell Creek Property).
In 1975, one of the best chip samples assayed 6.60 per cent copper, 156.00 grams per tonne silver and 156.00 grams per tonne gold across 0.91 metre (Assessment Report 5744).
In 1981, the best chip sample from Zone A yielded 0.94 per cent copper over 3 metres; 7.60 per cent copper, 2.82 grams per tonne gold and 100.4 grams per tonne silver over 3 metres from Zone B; 0.64 per cent copper over 1.5 metres from Zone C, and a grab sample from Zone D assayed 10.43 per cent copper, 0.34 gram per tonne gold and 44.7 grams per tonne silver (Property File Rimfire - Golden Rule Resources Ltd., 1981).
In 1991, a chip sample (4852) taken west of the B zone yielded 0.414 per cent copper, 13.0 grams per tonne silver and 2.28 grams per tonne gold over 0.7 metre (Richardson, P.W. [2007-08-30]: Technical Report - The McConnell Creek Property).
In 2008, drillhole MC-08-01 on the DWG Copper occurrence yielded two short (0.5-metre wide) intercepts of 1.73 and 0.92 per cent copper with 0.81 and 0.12 gram per tonne gold, respectively, within the top 8 metres of the hole (Assessment Report 31222).
In 2018, three outcrop samples (18RR-020, -021 and -023) from the occurrence area yielded from 11.4 to 20.1 per cent copper and 1.73 to 4.01 grams per tonne gold, whereas five samples (18RR-024, -025 and -030 through -031) from a second zone of copper-gold mineralization, located approximately 400 metres southwest of the main zone, yielded from 0.35 to 18.10 per cent copper and 0.09 to 1.21 grams per tonne gold (Assessment Report 38120).
Work History
In 1968, Velocity Surveys Ltd. completed a program of geological mapping, geochemical sampling and a ground electromagnetic survey on the area as the DWG, Ben and Dell claims of the McConnel Creek Copper property. The following year, an induced polarization survey was completed on the property.
In 1975, Houston Mining Ltd. completed a program of geological mapping and seven short rotary drillholes, totalling 21.0 metres, on the area as the Ben claims.
In 2005 and 2006, CGL Diamond Corp. completed programs of soil sampling on the area. In 2008, GGL Diamond Corp. completed three diamond drill holes, totalling 1071.36 metres; one hole tested an induced polarization target in the copper area in the west part of the property and two holes tested geochemical and geophysical targets near the main gold-bearing shear zone. Additionally, 87.95 kilometres of line cutting was completed on the property.
In 2018, GGL Resources Corp. conducted an exploration program consisting of the collection of 72 soil samples, 32 rock samples and 11character samples of historical drillcore. General geological and geomorphological observations were also made during the field visit. This work was conducted to better understand, evaluate and put in context the historical results collected on the property since 1981. In addition, and concurrently, a modern structural investigation and interpretation using Sentinel-2 and Landsat 7 imagery was commissioned.
In 2020, GGL Resources Corp. completed a 12.8 line-kilometre ground magnetic survey and a 11.7 line-kilometre induced polarization survey on the McConnell Creek property.
