At the Rose 1 showing, tan and white weathering blocky dolomite of the Middle-Upper Cambrian Jubilee Formation is cut by a fault zone trending 020 degrees and dipping about 75 degrees west. The dolomites along this zone are faulted and brecciated with the breccia healed by carbonate containing disseminations and patches of malachite and azurite with associated bornite, chalcocite and chalcopyrite.

A grab sample of malachite-azurite-rich material assayed 17.5 per cent copper. Chip samples in the area of the Rose 1 showing returned values in the order of 3.3 per cent copper and 12 grams silver. The fault breccia zone is variable in width and appears to be associated with a single fault zone which hosts both the Swansea (082JNW009) and Rose 1 showings.
