The Sheep Mountain phosphate occurrence is located on an east-west–trending ridge, approximately 1.2 kilometres northeast of Sheep Mountain.

Regionally, the area is underlain by a series of generally north-trending sedimentary rocks including dolomitic carbonate rocks of the Mississippian Etherington, Mount Head and Livingstone Formations (Rundle Group) and Pennsylvanian to Permian Rocky Mountain Group, fine clastic sedimentary rocks of the Triassic Spray River Group, undivided sedimentary rocks of the Jurassic Fernie Formation and undivided sedimentary rocks of the Jurassic to Cretaceous Kootenay Group.

Locally, at the Sheep Mountain showing, a 10- to 15-centimetre thick, phosphate-cemented, chert pebble conglomerate containing 13.8 per cent P2O5 unconformably overlies dolomitic siltstone of the Pennsylvanian Kananaskis Formation (Spray Lakes Group). This conglomerate is overlain by a phosphatic cherty sandstone bed 70 centimetres thick that contains 0.7 per cent P2O5 (Open File 1987-16), and which belongs to the Permian Johnson Canyon Formation (Ishbel Group).

Work History

In 2023, Fertox International Organic Inc. conducted a minor program of prospecting and rock sampling on the area as part of the Mt. Lyne Trend property.
