Dec 07, 2005 (S Fumerton) - At the 'Copper Breccia' the outcrop is cut by a number of closely spaced east - west faults. Between some of the fault planes there is some brecciation.

Dec 07, 2005 (S Fumerton) - The general geology of the Shunsby deposit is that of a banded iron formation within a sequence of felsic to mafic metavolcanics. This sequence is thought to be overturned, with felsic volcanics structurally overlaying and mafic volcanics structurally underlying the iron formation. The iron formation consists of two broad, closely spaced horizons of siliceous, lean sulphide iron formation. The upper Chert is characterized by a soft sediment conglomerate with chert clasts in a carbonate - sulphide - chert matrix. Gradations exist between polymictic to monomictic, clast supported to matrix supported. Separating the two cherts is a mixed assemblage of including a distinctive variolitic, pillowed mafic flow and graphitic shales. The Lower Chert is also a mixed assemblage but with cherts, argillaceous cherts, shales, and iron formations. The whole sedimentary / volcanic sequence has been intruded by a number of irregular dioritic plugs and late feldspar porphyry dykes. At the showing the conglomerate chert is the dominant original rock type which is locally overprinted by tectonic brecciation.

Dec 07, 2005 (S Fumerton) - In the outcrop fine grained pyrite occurs in argillaceous chert horizons. Within these horizons there is also a gradation in the sulphide concentration across strike. Sub-parallel to the fault planes are a number of massive and semi-massive pyrite - chalcopyrite veins up to 5cm thick. The sulphides in these veins tend to be coarser than the chert matrix and the veins have a limited strike length and are typically bifurcated. Sulphides also occur as discontinuous trails in late brittle hair line fractures within the chert. These features indicate the mineralization at the 'Copper Breccia' was probably remobilised during tectonism but originally derived from the host iron formations.
Dec 07, 2005 (A Wilson) - Grab samples collected by the OGS in 1970 returned values of 20.60 g/t Ag, 5.00% Cu and 0.73% Zn. Grab samples taken by the OGS in 1978 returned values of 15.00 g/t Ag, 3.3% Cu, 0.02% Pb and 0.75% Zn; 14.39 g/t Ag, 3.3% Cu, 0.02% Pb and 0.09% Zn.
