The Rothsay Gold Mine is located within the Warriedar Greenstone gold belt, an Archaean sequence of mafic, ultra-mafic, meta-volcanic and sedimentary rocks folded in an anticlinal formation which plunges and strikes to the north-northwest with steeply dipping limbs. The deposit is hosted in three discrete areas and within five individual shear zones. Woodley’s Shear (formerly A Shear), Woodley’s East and Hydra shears (formerly H Shear) occur to the east of the main Woodley’s Lode, Orient Shear (formerly B Shear) and Clyde and Clyde East Shears (formerly C and D Shears) occur in a second area further west and Miners Shear (formerly E Shear) occurs as an isolated shear in the northwest.The Woodley Shear is located at the contact between serpentinised peridotite and a porphyritic pyroxenite. Serpentinite forms the hanging wall unit. A sequence of mafic volcanic and sub-volcanic sills forms the hanging wall to the serpentinite.Woodley’s Shear is characterised by several generations of quartz veining with adjacent tremolite alteration. The early quartz phase is typically blue-black due to the partial replacement of alumina by chromium oxide. The shear zone is typically two to five metres thick, and mineralisation does not typically occur outside the shear zone. The main gold mineralisation is associated with shear-hosted quartz veins of blue and white quartz of up to 3m thickness. The footwall porphyritic dolerite is relatively unaltered, while the hanging wall serpentinite is strongly foliated and has been subject to intense, though patchy tremolite alteration.DimensionsThe Rothsay resource extents are 1,650m strike, 300m across strike and 550m below surface and open at depth. These extents host all interpreted ore lodes. The lodes vary between 0.1 to 2m in width.
