Old Shaft at Wheal Thomas/Watson mine is shown on the OS (1954) third edition map. The survey in 2002 found the shaft c1.5m x 1.5m filled with rubble from a masonry feature next to the shaft. The tall masonry wall c5m high x 0.95m thick was 4m wide at the base & c2.4m wide at the top with four timber joist holes. The feature may have been a high masonry mounting for a winding drum or related flat rod pumping mechanism. C5m to the south of the shaft at SX43607309 another masonry structure 3.2m x 2.1m x up to 2.5m high with a timber lintel appeared to have been a mounting plinth for an angle-bob. The flat rod cutting is partly shown on the OS (1884) map. Other details: Sites 371,371/1 & 372.
