Jun 23, 2023 (Q Unknown) - The deposit occurs within part of an extensive sequence of mafic metavolcanic rocks (Tudor Formation) which are intruded by a number of intrusive bodies, notably the Elzevir Granite. The OGS preliminary geological map P2278 (Moore and Morton, 1980) defines the volcanic rocks as basalt flows, pillow flows, pillow breccias, autoclastic breccias, amphibolite and hornblende schist. At the occurrence, Carter describes the country rocks as dark grey, weakly to strongly foliated, very fine grained mafic metavolcanics. Shear zones contain abundant biotite and often have a rusty appearance.
