Ystrad Einon Copper mine worked a NE-SW lode which is unusual in mid-Wales and is largely restricted to the Dovey estuary. Development of the mine below adit level did not start until the late 19th century with the sinking of a winze to the 12 fathom level in 1871. A 16 diameter underground waterwheel was installed for pumping and lifting; this allowed the mine to be deepened by another 12 fathoms.
