From 1693 to the mid-19th century, various people are reported to have explored the Edge for copper and work was done at Saddlebole, Stormy Point, Engine Vein and Brinlow. It is likely that the near-surface sections of Wood Mine were investigated during this period. One operator of note was Charles Roe of Macclesfield, who worked the mines from 1758 to 1768. During this period, copper from Alderley was taken to Macclesfield where it was combined with zinc from calamine ore from Derbyshire mines to make brass. Roe moved to Anglesey upon the discovery of major deposits of copper at Parys Mountain.
