The St. Paul claim was staked early in 1900 to cover a quartz vein, hosting pyrite and chalcopyrite. The vein cuts hornblende diorite of the Jurassic to Tertiary Coast Plutonic Complex. The vein is situated 6 to 8 metres above the waterline on the west shore of Pitt Lake. A selected sample is reported to have assayed about 30 grams per tonne gold and 4 per cent copper (Minister of Mines Annual Report 1900, page 938).
