The Clinton Manganese #2 occurrence is located approximately 3 kilometres southwest of Clinton on the northwest side of Junction Valley (Dolmage, 1944). It is about 0.8 kilometre east of the B.C. Rail track.

GSC Map 1278A (Memoir 363) shows the area to be underlain by basic volcanic flows, tuff, ribbon chert, limestone and argillite of the Permian to Triassic Cache Creek Complex. Marble Canyon Formation (also part of the Permo-Triassic Cache Creek Complex) limestone, limestone breccia and chert with minor argillite, tuff, andesitic and basaltic flows also outcrops in the area.

Dolmage (1944) states that the deposit is hosted in "quartzite" (chert ?) and a bright red shale unit and minor green shale. The "quartzites" (cherts ?) are intensely fractured and impregnated with black manganese oxides and hydroxides and are traceable for a hundred metres or so over widths of 15 or so metres. A sample taken by Mr. Olson assayed 33.4% manganese.
