The area south of Crater Lake is underlain by Lower Jurassic Hazelton Group volcanics of the Telkwa Formation comprised of andesitic to rhyolitic tuffs, flows, and breccias.

In 1986 sampling on the Kin 3 claim indicated high gold values from an occurrence located 125 metres south of the southeast area of Crater Lake along Miller Creek. The 0.15 metre sample assayed 3.22 grams per tonne gold, 14.0 grams per tonne silver, 4.6 per cent zinc, 0.02 per cent lead, and 0.09 per cent copper (Assessment Report 15546).

Further south, along the west side of Miller Creek a 10 metre adit was discovered. Just south of the adit, a 0.5 metre sample taken in 1986 assayed 7.9 grams per tonne gold, 26.0 grams per tonne silver, 0.015 per cent copper, 0.055 per cent zinc and 0.012 per cent lead (Assessment Report 15546). The property is part of the Mamie Group (refer to Mamie 093L 091).
