The Clinton Nickel occurrence is located approximately 7 kilometres southwest of Clinton. It is approximately 1 kilometre west of the Ashcroft road, and 150 metres (500 feet) above it.

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 outcrops west of the area. Cache Creek rocks are unconformably overlain by Cretaceous conglomerate and coarse clastic sedimentary rocks of the Miocene to Pleistocene Chilcotin Group.

GSC Memoir 110 (page 96) states that "an outcrop of calcareous quartz rock carries the green, nickeliferous silicate, garnierite". The outcrop is 8 metres by 3 metres and could be an "immense boulder". A chip sample assayed 0.11% nickel and 0.17% chromium oxide.
