The Eakin Creek copper occurrence is located on the south side of Eakin Creek, 7 (air) kilometres northwest of Little Fort.

A narrow shear zone containing pyrite, chalcopyrite and malachite near the eastern edge of a Harper Ranch Group limestone unit was found to contain 13,463 ppm copper, 12.6 ppm silver, 72 ppb gold, 13 ppb platinum and 62 ppb palladium (Sample 00SIS-29, Fieldwork 2000). The limestone can be traced from Nehalliston Creek in the north to Eakin Creek and is sparsely mineralized with chalcopyrite and locally galena (Assessment Report 13519).

The Upper Triassic to Lower Jurassic Dum Lake complex is comprised of ultramafic and mafic plutonic rocks that could be part of an Alaskan-type intrusive body. The mafic portions of the Dum Lake complex are dominated by coarse to medium-grained gabbro and diorite but locally includes clinopyroxenite, monzogabbro, microdiorite and tonalite. The ultramafic portion of the Dum Lake complex includes an assemblage of variably serpentinized, locally talc and carbonate-altered rocks consisting of clinopyroxenite, wehrlite and dunite. The Dum Lake complex is truncated by granodioritic rocks of the Triassic to Jurassic Thuya batholith on its southeast side. On its eastward side, Dum Lake complex diorites and gabbros are in contact with massive andesites of the Upper Triassic Nicola Group and argillites, limestones and cherts of the late Paleozoic Harper Ranch Group (Fieldwork 2000).

The showing was discovered during a geological mapping program (Fieldwork 2000). No work has been documented on the showing.
