South Wheal Hawke worked lodes adjacent to an ENE-trending elvan dyke in the southern part of the sett, across the boundary between Chacewater and Redruth parishes. The shafts formed a line that passed the A3047 road just south of the present A30 road. Most of the workings are now built over; only the eastern shafts remain in a field between the A3047 road and the railway line.

The occurrence of quartz-wolframite fragments in the dumps near Paull's shaft led to the search for a tungsten-bearing lode in the area. An attempt in 1938 to locate the outcrop by digging trenches in the neighbourhood remained unsuccessful. In 1942, Paull's shaft was re-opened. At a depth of 120 ft below surface, a level was driven through the old stopes for 120 ft to the west, where the copper lode, on which Paull's shaft was sunk, intersects with another lode; the drive was then turned on to this for another 150 ft. This lode was traversed by a series of late quartz veins with crystals of wolframite and cassiterite, but this ore differed from the material found on the surface. The source of the latter was not encountered in the investigations.
