Capsule Geology

The Cretaceous Horsethief Batholith intrudes Helikian Purcell sediments. The intrusion is zoned from fine-grained - medium-grained granodiorite to coarse-grained quartz monzonite.

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

The placer concentrations occur intermittently along Forster Creek and its tributaries for 12 kilometres. A heavy mineral fraction from the upper part of the creek assayed 0.11 per cent uranium (Assessment Report 6593).
