The Robin occurrence located south of the Tay River, approximately 2.7 kilometres north of Sutton Pass.

The area is underlain by highly chloritized, massive and commonly porphyritic and amygdaloidal basalt of the Upper Triassic Karmutsen Formation (Vancouver Group). The basalt contains thin interbeds of grey limestone and the sequence is intruded by quartz diorite of the Jurassic Island Plutonic Suite. Contacts between the volcanic and intrusive rocks are usually faults trending north, east or northwest with steep dips. Occasionally tremolite skarn is developed near limestone-quartz diorite contacts with associated carbonate veining. The skarn hosts small (1 to 5 centimetres) sections of magnetite, pyrite and chalcopyrite mineralization.

Locally, garnet-diopside skarn is evident. Shear zones within the basalt and quartz diorite, and basalt-quartz diorite contacts host thin (less than 50 centimetres) zones of quartz or carbonate veins with minor pyrite-chalcopyrite mineralization.

The Robin claims were initially staked in 1970 by Hudson Bay Exploration. In 1971 through 1980, a series of small programs of soil sampling, prospecting, geological mapping and minor trenching were conducted by Golden Hinde Mines. In 1987, Area Explorations and Snowfield Resources completed a preliminary program of rock and soil sampling. In 2007, the area was prospected by Perovic Enterprises as the Tay-Christina property.
