Dylife mine is located some 14 kms SE of Machynlleth, and was a major lead producer, with some copper and zinc. The first recorded working was about 1640 by Thomas Bushell although Dylife may be of much greater age, possibly pre-Roman, and may have been worked by the Romans sometime after 70 AD. The mine is known to have been at work again at various dates in the 18th centry, and from 1818 to 1891. The dumps were reworked in 1899-1901, and again in the late 1920s.

Recorded production from 1845 is 37000 tons of lead ore, 1540 tons of copper ore, 390 tons of zinc ore, and approx 160000 oz of silver.
