The Doyle occurrence is located near the mouth of Foulger Creek, on the west side of Howe Sound.

The area is predominantly underlain by quartz diorite of the Cenozoic-Mesozoic Coast Plutonic Complex, which contains a small pendant of Lower Cretaceous Gambier Group volcano-sedimentary rocks.

The occurrence is underlain by the northwest extension of the Britannia shear zone. The shear zone is up to 510 metres wide and is primarily comprised of sericite-quartz schist, possibly representing sheared latite and/or dacite sills. Mineralization, as exposed in former pits and trenches, consists of pyrrhotite, pyrite, chalcopyrite, sphalerite and galena associated with a chlorite schist.

Samples taken from the pits and trenches are reported to have assayed up to 0.75 per cent copper, 2.39 per cent zinc and 12.4 grams per tonne silver (Assessment Report 12187).

In 1958, Sound Copper Syndicate completed a geological mapping program on the area as the Sound claims. In 1981, Raft Mines completed a program of rock sampling, trenching and an air photo fracture density analysis on the area immediately south as the Clare claim. In 1984, Black Queen Resources completed a 55.2 line-kilometre airborne geophysical survey on the area as the Doyle 1-2 claims. In 1986, Fontana Resources completed a program of rock and soil sampling, geological mapping and a ground magnetometer survey on the area.
