Capsule Geology

The Squeak property is located nine kilometres northeast of Pemberton, immediately north of the Mount Currie Reserve. It is underlain by sedimentary and volcanic rocks of the Upper Triassic Cadwallader Group, preserved as a roof pendant within the Upper Cretaceous Spetch Creek pluton. The old Marjery showing and adit is located in this area.

Mineralization is hosted by limestone where it has been intruded by diorite and felsic porphyry dykes, thought to be part of the Spetch Creek pluton of which a granodioritic phase is exposed to the northeast. The limestone is interbedded with andesitic and rhyolitic tuff and breccia, argillite and minor conglomerate.

Two showings, 300 metres apart, consist of garnet-epidote- calcite-quartz skarns. The western showing is an eight-metre wide massive to semi-massive gossanous lens of pyrite and magnetite. The eastern showing consists of a limestone lens replaced along a northeast striking shear zone by garnet, epidote, clinopyroxene, calcite and quartz, with pyrite, magnetite, chalcopyrite and sphalerite.

A grab sample from the eastern zone assayed 20.8 grams per tonne silver and 0.57 per cent copper (Assessment Report 18013).
