The Chico showing is 550 metres northeast of Allison Creek, 950 metres east-southeast of the confluence of Allison and MacKenzie creeks.

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. To the south and west undivided volcanic rocks of the Lower Cretaceous Spences Bridge Group are exposed.

Locally, malachite occurs in a section of lahars, tuff and tuff breccia of the Lower Cretaceous Spences Bridge Group.

Another zone of mineralization is exposed in a roadcut approximately 1.3 kilometres to the southeast of the occurrence. The zone comprises a shear zone in basalts hosting pyrite.

In 2009, a chip sample (RE005129) from the shear zone yielded 0.165 gram per tonne gold over 1.3 metres (Assessment Report 31448).

Work History

Zone Explorations Ltd. completed a soil sampling survey over the area immediately north of the occurrence in 1970 as the On claims. In 1973, Aalenian Resources examined the area as the Liard Lake property.

In 2006, Tanqueray Resources Ltd. completed a program of rock, silt and soil sampling on the area as the McCaffrey property. In 2009, Solitaire Minerals Inc. completed a program of geological mapping and geochemical (rock, silt and soil) sampling on the area as the Rita-Chico claim.

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.
