The Raft 1 occurrence is located on a logging road on the northwest side of Raft Creek, approximately 5 kilometres north east of the creek mouth.

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 roadside outcrops host pyrite, chalcopyrite and sphalerite.

In 1986, BP Resources Canada completed a soil sampling program.
