In 1690, lead was discovered in Lead Mines Clough at Anglezarke. The mines were expanded in the 1790s and copper and galena were also extracted. Witherite (barium carbonate) was discovered around 1700, and used as a glaze for porcelain. Stone was quarried at several sites including Anglezarke and used for building farmhouses, barns, mills and stone boundary walls. There were small coal mines on Winter Hill and Quarlton.
