At the Red Rupert showing a quartz vein about 0.3 to 0.6 metre wide dips 45 degrees south. The vein is hosted in schist and gneiss of the Devonian Middle Triassic Boundary Ranges Metamorphic Suite.

The Red Rupert group of 2 claims was owned by B.J. Schwanekamp and Charles Hill, of Atlin, in 1933. Exploration work has been done in open cuts and an adit, said to be 9 metres long.

Three channel samples, across 0.3 to 0.6 metre vein widths, assayed 10.3 to 34.3 grams per tonne gold and 3.4 to 13.7 grams per tonne silver (Minister of Mines Annual Report 1933, page 80).

In 2007, research on the mineral potential of the Red Rupert tenure using satellite imagery was done on behalf of owner Alex Long. Iron oxide spectrometric responses in the higher elevation areas immediately southeast of the Red Rupert claim and north of Bighorn creek were significant but were found to be weak on the Red Rupert claim itself.
