At the Swansea occurrence, tan and white weathering blocky dolomites of the Middle-Upper Cambrian Jubilee Formation are 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 returned an assay high of 17.5 per cent copper. The fault-breccia zone is variable in width and appears to be located along a single fault zone which hosts both the Swansea and Rose 1 (082JSW007) showings.
