The Panther Road South showing is located south of the Panther Road showing (092F 439), about 22 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, and basaltic flows, diabase, agglomer- ates and bedded tuffs of the Upper Devonian McLaughlin Ridge Formation (Myra Formation).

A zone of semi-massive pyrite, up to 10 centimetres thick and 50 centimetres long, occurs in McLaughlin Ridge basalts ("Mine Flow Unit" of the Thistle mine, 092F 083).

In 1985, Westmin Resources completed a program of geochemical sampling, prospecting and geophysical surveys on the area. A sample across the mineralized zone assayed 2.1 grams per tonne gold (Assessment Report 13711).

In 1988, Nexus Resources completed a program of seven diamond drill holes, totalling 1205.4 metres, on the Thisle property. Diamond drill hole 88-01 encountered a stock work of hematitic quartz-carbonate veinlets ) containing disseminated pyrrhotite and chalcopyrite. Chloritic alteration is common, but epidote-carbonate- chlorite-quartz alteration is also present. Mineralization is associated with alteration. A sample containing disseminated chalcopyrite assayed 1.19 grams per tonne gold, 0.0024 per cent copper, 0.0023 per cent zinc, trace silver and trace lead (Assessment Report 17661).

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