Annotation
Seafloor sampling (25 samples weighing 5-7.5 kg) has established that the Permo-Carboniferous bedrock exposed over a coastal strike length of 5km near Doctors Rocks have yielded trace amounts of very fine placer gold to near-shore recent sediments. Longshore drift appears insignificant, and work to date has defined the western and eastern margins but the seaward extent remains undefined. The gravels are thin and their distribution is patchy. More detailed sampling was not conducted due to economic considerations and the area is relinquished.
