The Atluck occurrence is located on the south side of Atluck Creek, near the southwestern end of Atluck Lake.

The area is underlain by Upper Triassic Vancouver Group rocks comprised of Quatsino Formation limestones which overlie Karmutsen Formation volcanics. Lower Jurassic Bonanza Group volcanics overlie the Quatsino limestone.

Locally, subhorizontal northwest striking white recrystallized limestone of the Quatsino Formation is in contact with fine-grained amygdaloidal basalt of the Bonanza Group (Assessment Report 4818) or the Karmutsen Formation (Geological Survey of Canada Paper 4-1974). The basalt shows multidirectional shearing with associated epidote, quartz and locally prehnite and clay. The predominant fracture set trends 045 degrees, with a steep southeast dip. Mineralization occurs as fine chalcopyrite disseminations and fracture fillings, accompanied by pyrite, epidote and malachite.

Work History

In 1973, Groundstar Resources completed a program of geological mapping and an 18-kilometre ground magnetometer survey on the area as the Atluck 1-8 claims. During 2010 through 2014, Goldenlode Resources completed programs of geological mapping, prospecting and geochemical sampling on the area as the Atluck 1 claim.
