Capsule Geology

The Cretaceous Bugaboo Batholith intrudes Hadrynian Windemere sediments of the Horsethief Creek Group. The east part of the intrusion consists of medium-grained leuco-quartz monzonite to coarse-grained biotite quartz monzonite.

Black sand placer concentrations containing uranium-and niobium-bearing minerals occur in the outwash gravels from glacier action in the Bugaboo Batholith. Minerals include uraninite, allanite, rutile, titano-columbite, euxenite-polycrase, pyrochlore, monazite, uranothorite magnetite, ilmenite, apatite, andalusite, zircon, epidote, fluorite, garnet, hematite, pyrite, lepidocrocite, and sphene.

Placer concentrations are known to occur along the upper east branch of East Creek. Size and assay values are unknown.
