For people that don't know, south Australia hosts a huge copper sedimentary rock type syncline but has either already been mined 100s of years ago, or is too deep to be economic, like some are 400m deep layers of copper which is difficult to mine due to soft sedimentary rock
copper flats WA is also sedimentary rock type syncline, potentially shallower as EM conductors maybe an indication of shallow copper banding in sedimentary shale or sedimentary carbonates.
the biggest sedimentary mines in the world are in Congo and Zambia.
