The weathered gneiss was presumably cut by wedged end chisels rather than ‘gads’... on one section of the 375 m berm on the east side of the pit, seven remains or carbonised traces of woven baskets were found (Fig.11). In the same location timber supports, with verticals morticed into sole plates have been found (Fig. 12). In other areas shafts with footholds had been sunk working almost vertical shoots of ore in a joint or possibly a shear zone... "Galleries visible seem to have been of walking height, the chisel marks in the usually soft rock clearly visible".
