The property is underlain by Lower Jurassic Hazelton Group vol- canics of the Nilkitkwa Formation. They are comprised of maroon to green to grey andesite with basaltic to dacitic pyroclastics including dense, fine-grained tuff, vitric tuff, lapilli tuff, lahar and coarse to fine-grained breccia. Mineralization consisting mainly of pyrite, chalcopyrite, and tetrahedrite occurs in quartz veins and quartz-carbonate infillings in faults and fractures within the andesitic tuffs and amygdaloidal basalts.

A lenticular quartz vein, approximately 15 centimetres wide strikes 085 degrees and dips between 50 degrees south to near vertical. The vein consists of quartz, tetrahedrite, chalcopyrite, galena, sphalerite, and pyrite. In 1937, 8.2 tonnes of ore was shipped from this vein and produced 93 grams gold, 21,928 grams silver, 190 kilograms copper, 327 kilograms lead, and 245 kilograms zinc (Minister of Mines Annual Report 1937, page C33).

Approximately 15 metres above these workings are two minerali- zed quartz veins which strike 005 degrees and dip 40 degrees east and 295 degrees and dips 67 degrees south. The former is terminated by a fault in the altered andesitic tuff which strikes 320 degrees and dips 55 degrees southwest. Mineralization in the quartz stock- works and veinlets occurs as disseminations of tetrahedrite, chalcopyrite, bornite with minor chalcocite, covellite, malachite, and azurite.

Another type of mineralization on the property occurs as lensoid veins along shears and faults which are genetically related to the southeast trending regional direction of shearing and fracturing. Mineralization occurs in quartz, carbonate or sideritic infillings with clots and masses of tetrahedrite and chalcopyrite. In 1977 a selected sample from the Driftwood high grade vein assayed: 9.3 per cent copper, 1080.7 grams per tonne silver, and 2.4 grams per tonne gold (Assessment Report 6610).

Barite veinlets also crosscut the volcanics. In 1977 a barite vein chip sample assayed 0.13 per cent copper, 35.3 grams per tonne silver and 0.14 grams per tonne gold (Assessment Report 6610).

On the Judge No. 1 claim, mineralization is concentrated along silicified zones paralleling beds of tuff. Pyrite, chalcopyrite, bornite, and tetrahedrite occur in two beds confined to a maroon breccia lying between beds of fine-grained reddish tuffs. In 1937 a 647 kilogram sample assayed: 1028 grams per tonne silver, 40.5 grams per tonne gold and 10 per cent copper (Minister of Mines Annual Report 1937, page C33). In 1939 another 0.49 tonne sample assayed 19.5 grams per tonne gold, 1378 grams per tonne silver, 12 per cent copper, 0.9 per cent zinc, and 1.65 per cent antimony (Minister of Mines Annual Report 1939, page A59).

In 1937, about 9 tonnes of ore was shipped from the Driftwood property. From this ore 93 grams of gold, 21,928 grams of silver, 109 kilograms of copper, 327 kilograms of lead and 245 kilograms were recovered.
