The Zoo 2 occurrence is located on a ridge, approximately 1.7 kilometres south of the junction of Willis and Creek and the Raft River.

The area is underlain by Lower Paleozoic Eagle Bay metasediments consisting of phyllite, chlorite-sericite-quartz schist and black graphitic schist. A northeast trending fault cuts the schist and to the north has been intruded by the granitic Cretaceous Raft Batholith.

Locally, a 2 to 5 centimetre bed or band of massive pyrite with galena is hosted by siliceous quartz-sericite schists and quartz-biotite schists. The host rock contains up to 10 per cent pyrite.

In 1986, BP Resources Canada completed a soil sampling program and identified an anomalous area of copper-zinc values. In 1991, Minnova completed a program of geological mapping on the area as the Zoo 1-5 claims.
