The Aitken Gold occurrence is based upon a gold occurrence shown on Map 1082A of Geological Survey of Canada Memoir 307. It is located about 5 kilometres southeast of the community of Atlin and only 1 kilometre from the eastern shore of Atlin Lake.

The showing is located within upper Mississippian to Permian ultramafic rocks of the Cache Creek Complex. These are composed largely of peridotites which are commonly talc and serpentine altered.

A brief description of the showing in 1899 says it is composed of quartz veins hosting galena mineralization and malachite staining. It also suggests the hostrock and vein are iron-carbonate altered and silicified. This description sounds similar to other occurrences in the area such as the Anaconda, Pictou and Anna (104N 046, 44, 101, respectively) which are comprised of mineralized quartz and calcite veins hosted in carbonate altered and silicified ultramafic rocks. They are often referred to as listwanitic-type occurrences, commonly containing chromium mica such as fuchsite (mariposite).

The area around the Aitken Gold occurrence has been staked on several different occasions, but no information has ever been documented on work done specifically on it.
