The Al occurrence outcrops along a roadcut 170 metres northwest of Allison (Ketchan) Creek and 1.3 kilometres northeast of the north end of Allison Lake.

Regionally, the area along the Allison Creek valley is underlain mostly by biotite hornblende granite and quartz monzonite of the Upper Triassic to Lower Jurassic Allison Lake pluton. More mafic phases, comprised of granodiorite, diorite and gabbro, are occasionally present within and along the periphery of the intrusion. The north-trending contact with Upper Triassic Nicola Group andesite and basalt lies east of the valley and comes to within a kilometre east of Allison Lake. The pluton is traversed along the east side of the valley by the north-striking Allison fault.

Locally, three narrow northwest-trending shear zones occur in granite of the Upper Triassic to Lower Jurassic Allison Lake pluton, over a distance of 40 metres along the roadcut. The shears are mineralized with chalcopyrite and malachite. A short distance east of the shear zones, near a southwest-flowing creek, a historical pit exposes a copper-bearing quartz stringer.

Work History

The occurrence area was initially geologically mapped and soil sampled by J.R. Poloni in 1972 as the Al claims. Territorial Petroleum Ventures Ltd. conducted additional geological mapping and geochemical (silt and soil) sampling in 1981 and 1983 on the Al claims.

In 2009, Orofino Minerals Inc. completed a 922.0 line-kilometre airborne magnetic and gamma-ray spectrometer survey on the area as part of the Allison Lake property. The following year, Orofino Minerals Inc. completed a program of prospecting, geological mapping, geochemical (rock, silt and soil) sampling and 57.0 line-kilometres of ground magnetic and induced polarization surveys on the Allison Lake property.

During 2012 through 2015, Colorado Resources Ltd. completed programs of geological mapping, geochemical (rock and soil) sampling and a 6.0 line-kilometre induced polarization survey on the area as the Hit-Aspen Grove property.

In 2019 and 2021, Independence Gold Corp. explored the area as the Anita property.
