Triassic volcanics and metavolcanics are intruded by quartz diorite and granodiorite of the Cretaceous to Tertiary Coast Plutonic Complex. The volcanics consist mainly of rhyolites, porphyritic andesite flows, and minor basalt. All rocks are cut by feldspar porphyry dykes, faults, and shear zones with associated quartz veins.

The volcanics and veins carry pyrite, sparse bornite and chalcopyrite, minor skarn minerals, and, in places, some scheelite. A 75 centimetre sample of a silicified zone assayed trace gold, 34.3 grams per tonne silver and 1.2 per cent copper (Minister of Mines Annual Report 1939).

Bulk samples shipped to the Provincial Sampling Plant at Prince Rupert in 1941 and 1945 assayed as follows:

_________________________________________________________________

Tonnes Gold (grams) Silver (grams) Copper (per cent)

0.469 13.71 397.7 8.38

(Minister of Mines Annual Reports for 1941, page 41; and 1945, page 52). In 1953, about 1.0 tonne of ore from this property produced 62 grams of silver and 59 kilograms of copper.
