Several small abandoned prospect pits and an adit, in pyrite-rich schists (up to 50% pyrite) of a 46 meter wide zone in the Paleozoic Tumuru Formation. Small patches of this rock contain chalcopyrite(?) in addition to pyrite, but maximum analyzed Cu content of the rock was only an uneconomic 0.245% Cu. Blue-green secondary Cu minerals comprise minor stains on rock where springs emerge from cracks.
