A cotton mill was built by the stream at White Coppice. At first it was powered by a waterwheel but later the mill lodge was built to provide water for the steam engine. Around 1900 the mill was owned by Alfred Ephraim Eccles a supporter of the Temperance movement. Another small mill was built on the bank of the River Yarrow at the end of Bradley Wood of which no trace remains. Roger Lester lived in Anglezarke in 1769. The mill gave its name to the Lester Mill Quarry, a major contributor to the economy in the 19th century producing gritstone flags, stone setts and kerbs for paving the streets of the industrialised towns. Between 1880 and 1920, quarry men, sett-makers and two blacksmiths were employed. Dressed stone was carted to Adlington station for transport. The quarry is no longer operational. Millstones were produced at Black Coppice, where some remain.
