The Gird occurrence is a copper-silver showing, 1.5 kilometres north-northwest of Girdwood Lake, 13 kilometres north-northwest of the west end of Franklyn Arm of Chilko Lake. Copper-bearing talus is present north and south of Girdwood Lake, and the showing was found by prospecting upslope (Bulletin 81).

The showing is underlain a unit of Upper Cretaceous Powell Creek Formation volcanics forming an open syncline bounded by the Tchaikazan fault to the northeast and the Stikelan fault to the southwest (Bulletin 81; Geological Survey of Canada Open File 1163).

The area is part of the overlap assemblage, about 10 kilometres from the northeastern margin of the Late Cretaceous to Paleocene granodioritic Bendor suite, which forms part of the eastern boundary of the Coast Plutonic Complex.

The volcanics comprise purplish andesitic breccia and tuff, with minor flows. Some greywacke and conglomerate also occur in the unit. Bedding, the synclinal axial surface trace, and the bounding Tchaikazan and Stikelan faults all strike or trend northwest.

The volcanic unit hosting the Gird occurrence is characterized by widespread fracturing and quartz-epidote veining (Bulletin 81; Fieldwork 1986). Locally there are zones of epidote alteration up to 2 metres in width, within which are quartz-carbonate veins and vein breccias containing small amounts of native copper, tetrahedrite and malachite mineralization. Prehnite is a common accessory mineral in vuggy cavities in the veins.

Five samples analyzed from the showing ranged between 0.9 and 7.5 grams per tonne (average 3.62) silver, and between 0.22 and 1.49 per cent (average 0.734) copper; they were also somewhat anomalous in mercury and antimony (Bulletin 81). An isolated sample in similar rocks 2.5 kilometres west of the Gird showing was analyzed at 7.5 grams per tonne silver and 1.1 per cent copper (Open File 1987-14; Bulletin 81).
