The Cro NE phosphate occurrence is located at an elevation of approximately 1520 metres on a southwest-facing slope approximately 2.3 kilometres north of the north end of Summit Lake in the Crowsnest Pass area.

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, pelletal phosphorite is contained in two beds separated by phosphatic shale at the base of the Jurassic Fernie Group. The top of the phosphate horizon is marked by a thin yellowish weathering cherty limestone bed. The phosphate generally strikes north with shallow to moderate dips to the west. Thrust faulting complicates the distribution of the phosphate, causing the repetition of beds at some localities and causing the same beds to disappear in other locations.

In 2015, drillhole CRO-15-01 intersected the phosphate horizon at a depth of 23.66 to 27.60 metres (4.7 metre interval) and averaged 16.87 per cent P2O5, whereas drillhole CRO-15-02 intersected the phosphate horizon at a depth of 31.05 to 34.70 metres (3.65 metre interval) and averaged 20.56 per cent P2O5 (Assessment Report 36038).

Work History

A completed exploration history of the area can be found in the Crow (MINFILE 082GNE031) occurrence.

In 2015, High Brix Manufacturing Inc. completed a program of trenching and eight diamond drill holes, totalling 263.9 metres, on the area as part of the Cro property.
