The Panther skarn occurrence is located on a ridge east of Worthless Creek, approximately 3 kilometres north west of its junction with the Nitinat River.

A skarn zone of undetermined extent is developed at the contact between limestone of the Upper Triassic Quatsino Formation (Vancouver Group) and hornblende granodiorite of the Early to Middle Jurassic Island Plutonic Suite. Several well-defined dykes also occur.

At the Panther showing an opencut crosscuts a mineralized skarn approximately 90 centimetres wide, striking north and dipping 37 degrees west. Chalcopyrite and pyrrhotite apparently are the main sulphides. Garnetite is developed in a portion of the zone.

A grab sample from the opencut assayed 3.8 per cent copper and 13.71 grams per tonne silver. A second sample from the garnetite assayed 0.2 per cent copper (Minister of Mines Annual Report 1918, page K299).
