Capsule Geology

The Gord Davies (West) showing consists of a 20 to 100 centimetre wide siliceous zone, exposed over a strike length of 3.0 metres (Assessment Report 18335). The showing is located 6.25 kilometres southwest of Breccia Peak, west of Moosehorn Creek and south of Hiamadam Creek in the north-central part of the Toodoggone gold camp. Smithers is located 310 kilometres to the south.

The showing is situated within a Mesozoic volcanic arc assemblage which lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Tertiary sediments, volcanics and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins.

Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Takla Group andesite flows and pyroclastic rocks. These Takla rocks have been intruded by plutons and other bodies of the mainly granodiorite to quartz monzonite Early Jurassic Black Lake Suite and are in turn unconformably overlain by or faulted against Lower Jurassic calcalkaline volcanics of the Toodoggone Formation, Hazelton Group.

The dominant structures in the area are steeply dipping faults which define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high angle, northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.

The Gord Davies (West) showing is underlain by volcanics of the McClair Member of the Toodoggone volcanics. At this location they are composed of interbedded porphyritic flows, flow breccias, crystal tuffs and crystal lithic breccias. Minor volcaniclastic sediments are also present. Intensely fractured, porphyritic monzodiorite dikes cut the above.

These lithologies show generally weak chlorite and carbonate alteration. Feldspar matrix and phenocrysts are weakly affected by sericitic and argillic alteration. Takla volcanics outcrop immediately to the east.

The showing consists of a 20 to 100-centimetre wide siliceous zone, exposed over a strike length of 3.0 metres. The zone strikes 035 degrees and dips near vertically. Cubic galena was observed (Assessment Report 18335). Sample GD-88-002, taken from this zone, analysed 5.14 grams per tonne silver, 0.137 gram per tonne gold, 1.30 per cent lead and 1.75 per cent zinc (Assessment Report 18335).
