Capsule Geology

The Jacobe 2 occurrence is located on a small peninsula extending into Jacobie Lake.

The geology of the region consists of Upper Triassic to Lower Jurassic sedimentary and volcanic rocks of the Nicola Group, which are cut by northeast-striking normal faults. The stratigraphy of the lower part of the Nicola Group comprises Upper Triassic sedimentary rocks overlain by green and grey basaltic breccia, in turn overlain by maroon basalt. In this area the uppermost Upper Triassic unit is red sandstone which overlies maroon basalt.

The maroon basaltic unit was, in part, deposited subaerially and consists of vesicular flow breccias with amygdules of calcite and zeolite. In places chalcocite, covellite, cuprite, malachite, azurite, chrysocolla and native copper also occur as disseminated, fracture fillings and in amygdules. Quartz-carbonate-ankerite alteration zones associated with northeast-striking faults also contain minor amounts of copper mineralization.

In 1984, two rock samples (36409 and 36414) assayed 0.480 and 0.143 per cent copper, respectively (Assessment Report 25960).

In 1966, Chataway Explorations completed a soil sampling program on the area. In 1972, Sunshine Valley Minerals completed a program of geological mapping and rock sampling on the area as the B claims. In 1984, Hennessy Resource Corp. completed a program of rock and soil sampling and geological mapping on the area as the Jacobe 2 claim. In 1990, Pamicon Developments prospected and conducted rock sampling in the area as the JC 1 and 2 claims. In 1999, a program of rock sampling, trenching, geological mapping and a 5.6 line-kilometre ground magnetic survey were completed on the area as the J 1-4 claims. In 2001, Phelps Dodge Corporation of Canada completed a program of geological mapping and rock and soil sampling on the area as the Morehead 1-3 claims. In 2011, Eagle Peak Resources completed a program of geological mapping and rock and soil sampling.
