Lisheen Mine, Moyne, Tipperary

The Lisheen Mine is closed, having ceased production in 2015


The mine produced lead and zinc concentrates derived from sulphide rich ore hosted in dolomitised limestone.

Acid generating tailings from processing of the ore were deposited using the sub-aqueous technique in a fully composite lined tailings management facility (TMF), which is located on a peat bog.

The TMF is the largest fully lined tailings storage facility in Europe

Surface water run-off that falls on the TMF is converged into an engineered attenuation pond through three spillways. On exiting the pond, the surface water flows along an open channel, through another attenuation pond and out through the Clogheen stream and finally entering the Drish River.
