This map shows the layout of the lodes within the East Caradon sett. The sett boundary is shown shaded in yellow and blue, and the blue line waving its way across the bottom of the map marking the junction between the granite and killas. West Rosedown Mine lies to the north, South Caradon to the west and Glasgow Caradon to the east.  The lodes are shown as red lines and all lie within the granite with a general east to west trend and northerly dip. Mark's, Seccombe's, Fawcett's and caunter lodes are named as well as Seccombe's, Engine and William's shafts. In 1863 the mine had reached a depth of 90 fathoms and the building to the west as of Mark's lode was in use as the count house, as marked by the *.
At the time of the maps production the Kilmar Junction railway had not been built and the LCR railway terminates within the East Caradon Mine.

It is the Caunter lode that would provide most of the mineral wealth of the district and this can be traced on the map running through South Caradon, East Caradon and Glasgow Caradon mines.
