In 1581 a commission investigated ways in which extra royal revenues might be gained. By then Shining Cliff and the manor of Alderwasley had been transferred to the Lowe family, leaving the three wards of Duffield, Belper and Hulland. It reported that the game had virtually disappeared and much of the area was held in common by tenants and copyholders who would suffer if the woods were enclosed. They suggested developing the facilities for smelting the ores and a charge on lead similar to that levied in Wirksworth.
