The Keily Creek occurrence is located near the south end of a north-south–trending ridge, north of Keily Creek and approximately 16.5 kilometres north of Redfern Lake.
Regionally, the area is underlain by Devonian Stone Formation dolomites, which are thrust over Devonian and Carboniferous Besa River Formation shales to the east and Middle Devonian Dunedin Formation limestone to the southeast. The Besa River Formation apparently conformably overlays the Dunedin Formation.
Locally, disseminated galena and sphalerite occur in a cherty horizon at the contact between the Besa River Formation and the Dunedin Formation that can be traced for 1600 metres along strike. A sample (TL-5A) of dark grey, silicified dolomite containing barite and locally some galena from the occurrence area assayed 1.26 per cent lead (Assessment Report 4484).
