The Clinton Manganese #4 occurrence is located approximately 5.6 kilometres southwest of Clinton. It is just west of the B.C. Rail track on a small ridge that trends about 350 degrees. The showings trend along the ridge for about 100 metres, about 125 metres abovbe the track.

GSC Map 1278A (Memoir 363) shows the area to be underlain by massive limestone, limestone breccia and chert with minor argillite, tuff, and andesitic and basaltic flows of the Marble Canyon Formation of the Permian to Triassic Cache Creek Complex.

EMPR Minister of Mines Annual Report (1948, page A91) states that lithologies in the vicinity are largely grey and grey-green quartzose schists with interlayers of white, pink and red cherty layers. The strata strike 335 degrees, dipping 45 degrees southwest. A stratigraphic thickness of about 15 metres is exposed on the ridge, with secondary manganese oxides deposited on fracture surfaces. Although it could not be positively identified, rhodonite was suspected as the primary manganese mineral. Although most of the ridge is estimated to assay about 0.75% manganese, a 3 metre open-cut at the north end of the exposure containing "well mineralised" rock, with pyrolusite in vertical stringers to 2 centimetres wide. A 3.1 metre sample assayed 15.8% manganese.
