Capsule Geology

The Wapiti East and Farm showings are located approximately 152 kilometres northeast of the town of Prince George. They are approximately 43 kilometres from the British Columbia–Alberta border, in the Liard Mining Division.

The region is underlain by an assemblage of sedimentary rocks consisting mainly of continental margin and shelf facies rocks. This assemblage was deposited on and to the west of the Ancestral North American craton. These sedimentary rocks, for the most part typical continental shelf slope and basin facies, range in age from Hadrynian to Upper Cretaceous. Structurally these rocks are part of the Foreland thrust and fold belt of the North American Cordillera.

In this region phosphatic beds are commonly found in upper Paleozoic to lower Mesozoic rocks. These are exposed to the west of a major thrust fault that has thrust these rocks over younger, mainly Cretaceous strata. The Cretaceous strata are exposed to the east.

Phosphate nodules occur in a 1- to 2-metre thick sandstone bed at the top of the Permian Mowitch Formation. This sandstone bed is underlain by a 2- to 3-metre thick chert horizon. The phosphatic sandstone bed can be traced along strike for a minimum of 100 metres.

Phosphate nodules comprise 40 to 60 per cent of the sandstone bed by volume.

The Permian sequence is underlain by Mississippian carbonate strata and unconformably overlain by siltstone of the Vega-Phroso member of the Triassic Sulphur Mountain Formation.

In 1998, the area was staked as the Farm claims.

More recent and extensive exploration and development has been undertaken at the Wapiti Phosphate showing (MINFILE 093I 039), located 5 kilometres south-southeast.
