The Gibson Jenny occurrence is located on the north western side of the Clayoquot Arm of Kennedy Lake, approximately 2.5 kilometres north west of Duck Island.

The area is underlain by the contact of the Mesozoic and/or Paleozoic Westcoast Complex and granodiorite of the Early to Middle Jurassic Island Plutonic Suite (Tofino Inlet Pluton). The Westcoast Complex rocks are of andesitic composition and were likely derived from Paleozoic Sicker Group volcanics. The volcanics are located to the north and east of the contact and the intrusives to the south and west.

The contact zone is characterized by considerable northwest- trending sericitic shearing mineralized with disseminated pyrite. Samples of quartz vein material from the shear zone contained pyrite and chalcopyrite but when assayed did not contain significant gold.

During 1981 through 1985, Tinto Gold Corp. completed programs geological mapping, rock, silt and soil sampling and a VLF-EM survey on the area as the Gibson Jenny property.
