The Tyger occurrence is situated on the north flanks of Mount Nation, approximately 56 kilometres southeast of Takla Landing. The area was mapped and geochemical and geophysical surveys were carried out by Amoco Canada Petroleum in 1973.

The Mount Nation area is underlain by mesozonal plutonic rocks assigned to the Late Triassic to Early Cretaceous Hogem Intrusive Complex which have intruded volcanic and sedimentary rocks of the Middle Triassic-Lower Jurassic Takla Group east of the Pinchi fault zone. The plutonic rocks form an elongate batholith, extending from Chuchi Lake, north to the Mesilinka River.

The only reference to the Tyger occurrence describes chalcopyrite occurring as coatings on widely-spaced fractures cutting hornblendite and dioritic phases of the Hogem Intrusive Complex which have been intruded by granodiorite-quartz monzonite bodies (Geology, Exploration and Mining in British Columbia 1973, page 366).

This occurrence may be related to the Nation Mountain occurrence (093N 113), discovered in the same general area by Amoco Mining in 1971.
