Key Information
Do not enter mining areas without proper authorization.
The Mogul Mine is located in the Silvermines District, Tipperary County, Munster, Ireland, near the village of Silvermines, about 9.6 km from Nenagh and 39 km from Cashel, known for the Rock of Cashel.
It is famous for zinc and lead, with notable minerals like sphalerite and galena, and uncommon silver minerals such as acanthite and argyrodite.
The mine operated from 1968 to 1982, producing over 10 million tons of ore, and is now abandoned and flooded, with a history of mining dating back to 1289.
The host rock is likely limestone or dolomite, formed through hydrothermal processes in sedimentary rocks.
The area has a temperate maritime climate, with Special Areas of Conservation in the Silvermine Mountains, supporting unique plant communities adapted to heavy metal-rich soils.
Location and Geography
