The Leckie, Magee and Margarita polymetallic veins are exposed in trenches on the south shore of Carpenter Lake and in a trench on the road along the south shore of the lake, about 8 kilometers east of Gold Bridge. Several quartz veins, from a few centimetres to 4 metres thick, are hosted in foliated cherty greenstone of the Mississippian to Jurassic Bridge River Complex (Group), and peridotite-serpentinite-listwanite of the Permian and older Shulaps Ultramafic Complex.

The Leckie vein is in a southeast striking, west dipping shear in serpentine and/or gabbro near the contact with a felsite dyke. Irregular lenses of quartz-carbonate "listwanites" form several ore shoots up to 4 metres in width and consist of arsenopyrite, sphalerite pyrite, chalcopyrite, galena, tetrahedrite and mariposite and talc alteration products. Drill hole assays grade 35.6 grams gold per tonne, 404.6 grams silver per tonne across 1.5 metres.

The Magee showing (46 metres above the Leckie vein) is a strong 15 to 45 centimetre quartz vein in a 1 to 1.5-metre felsite dyke. Sphalerite, magnetite, pyrite, chalcopyrite and galena occupy up to 75 per cent of the vein. A sample taken across 40 centimetres graded 5.3 grams gold, 127.9 grams silver and 0.15 per cent copper, 0.67 per cent lead, 0.89 per cent zinc and 8.53 per cent arsenic (George Cross News Letter No.6, 1986).

The Margarita Zone, 50 metres west of the Leckie and Magee Zones, contains abundant arsenopyrite, pyrite and minor stibnite, accompanied by gypsum. The extension of the main 1-metre thick vein is exposed at the road and consists of quartz and calcite with arsenopyrite, pyrite, sphalerite and minor galena. The main vein appears banded, parallel to vein margins, with respect to the distribution of gangue and metallic minerals.
