The Panther showing is located between the Panther Road (092F 439) and the Panther Road South (092F 440) showings, about 23 kilometres southeast of Port Alberni.

Basaltic flows and pillowed basalt of the Upper Triassic Karmutsen Formation (Vancouver Group) are underlain by a complexly interlayered succession of volcanics and sediments of the Paleozoic Sicker and Mississippian to Lower Permian Buttle Lake groups. These include limestones and marbles of the Upper Pennsylvannian to Lower Permian Mount Mark Formation (Buttle Lake Group), and basaltic flows ("Mine Flow Unit" of the Thistle mine, 092F 083), agglomerates and bedded tuffs of the Upper Devonian McLaughlin Ridge Formation (Myra Formation), Sicker Group.

Copper-gold mineralization (likely pyrite and chalcopyrite) occur in basaltic rocks of the McLaughlin Ridge Formation.

In 1985, Westmin Resources completed a program of geochemical sampling, prospecting and geophysical surveys on the area. A sample assayed 2.47 grams per tonne gold and 0.16 per cent copper (George Cross News Letter #96, 1985). Chloritic alteration is common, but chlorite-epidote-carbonate-quartz alteration is also present.

In 2006 and 2007, programs of soil geochemical sampling were completed on the Panther claim by L. Stephenson for owner G. Wells.
