The Summit graphite occurrence is located west of the Crooked River and approximately 500 metres northeast of the northeast end of Peculiar Lake.

Regionally, the area is underlain by basaltic volcanic rocks of the Mississippian to Permian Antler Formation (Slide Mountain Group) and the Triassic to Jurassic Takla Group, and paragneiss metamorphic rocks of the Upper Cretaceous to Eocene Wolverine Metamorphic Complex, which have been intruded by pegmatitic, granitic and granodioritic rocks of the Cretaceous Wolverine Range Plutonic Suite.

Locally, graphitic, pyritic argillaceous schists overlie a series of graphitic, thinly bedded limestones. Quartz-muscovite- microcline pegmatites intrude into the sediments as large discontinuous irregularly shaped dikes or small boudins to boudinaged sills and dikes. Massive graphite occurs as pods and lenses within the pegmatite.

Work History

In 1981, Placer Development Ltd. completed a program of geological mapping, geochemical (rock and soil) sampling and a ground electromagnetic survey on the area as the Summit claim. During 1987 through 1989, Cominco Ltd. completed programs of rock, lake sediment and soil sampling on the area immediately southwest of the occurrence as the Mert 1-4 claims. This work identified gold-in-soil and gold-in-lake sediment anomalies.
