The Kimbarb showing is located near the mouth of Tulip Creek about 24 kilometres north of Castlegar, just north of Lower Arrow Lake.

The area is underlain by the Ladybird granite of the Lower Cretaceous (?) Valhalla complex. The complex, comprising granite and granodiorite is cut by pegmatite dykes related to the Middle Eocene Coryell Intrusion.

A sulphide vein, trending 315 degrees and dipping about 60 degrees, cuts the granodiorite. Sulphides consist mainly of pyrr- hotite, pyrite and minor magnetite. Minor molybdenite flakes are associated with the mineralization and are disseminated in the granodiorite near the pegmatite dykes.

Xenoliths of skarn were found within the granite. The xenoliths are thought to be remnants of the Pennsylvanian to Permian (?) Mount Roberts Formation limestone now altered to skarn by the intrusives. Garnet, olivine and calcite are reported to be well developed in the skarn and apparently a previous owner used this skarn as a source for semi-precious gemstones (garnet and olivine).
