Geological Age: Neoarchean
Metamorphism Type: Regional
Metamorphism Grade: Greenschist
Dec 07, 2005 (A Wilson) - A ductile shear parallel to the stratigraphy hosts the mineralization. Five to ten metres from the shear, the gabbro/diortie body is massive. In the massive phase, there are several ages and orientations of epidote, feldspar and carbonate veins filling fractures and forming a stockwork. Closer to the shear zone there is a progressively more strongly developed foliation associate with erratic conjugate quartz veins. From these veins and other veins which have been dragged, a sinistral movement occurred along the shear. One shear zone is well developed extending the length of the stripped outcrop varying between one and five metres thick. Minor splays emanate from this shear zone and parallel, poorly developed subsidiary shears do occur.

Dec 07, 2005 (A Wilson) - The mineralization is hosted in an altered gabroic flow within a south facing homoclinal sequence. Other units in the sequence include massive and pillowed flows, thick wedges of conglomerate below the mineralized gabbro and some argillaceous wacke horizons above the mineralized gabbro. Locally, on the upper contact of the gabbro, there are thin horizons of interflow siltstone. The mineralized gabbro may represent a subvolcanic sill, or a 200m thick flow and has been traced 2.7 km and corresponds to a magnetic high.

Dec 07, 2005 (A Wilson) - Mineralization occurs as disseminated sulphides in the shear zone and within attenuated quartz veins hosted within the shear zones and orientated parallel to the zones. Sulhides are unevenly distributed in the stripped area and form local rusty spots with up to 15% pyrite and lesser arsenopyrite. These sulphides occur in trails of medium to coarse grained material along shear planes or in some places, as very ocars subhedral grains between shear planes. The quartz veins tend to be single veins, but there is some quartz stockwork developed. Arsenopyrite is variable distributed in these veins either in coars disseminated grains, or as massive, to fine grains in composite bands. Grab samples collected by the OGS in 1992 returned values of 4.8 g/t Au and 3.46 g/t Au. A chip sample returned a value of 0.89 g/t Au.
