The Pat 1 showing is located just southwest of Douglas Peak, about 12 kilometres southeast of Port Alberni.

Basalts of the Upper Triassic Karmutsen Formation (Vancouver Group) are overlain by siltstones of the Cretaceous Nanaimo Group and intruded by diorite of the Early to Middle Jurassic Island Plutonic Suite.

Chalcopyrite occurs in altered basalt, likely associated with a shear. A grab sample assayed 1.66 per cent copper, 14.8 grams per tonne gold and 0.88 grams per tonne silver and another nearby grab sample assayed 2.7 grams per tonne silver (Assessment Report 15192). In 1990, rock sampling returned up to values up to 2900 parts per billion gold, 16,600 parts per million coper, and 14.8 parts per million silver (Assessment Report 20824).

This showing is near the Webb showing described by Laanela in 1966.
