Boliden, the Swedish owner of Tara Mines in Co Meath, is to invest €44 million in the site after identifying new mineral resources and deciding to expand the mine’s tailing dam.
The mine, which is just outside Navan, is Europe’s largest, and the world’s ninth largest zinc mine. It currently employs over 600. Production at Tara Mines began in 1977, and since then more than 80 million tonnes of ore have been mined.
Boliden Mines said a recent exploration has resulted in the discovery of a new mineralisation Tara Deep. An extension of the capacity of the tailings dam, which currently limits Tara’s lifespan, has also been decided. The new tailings dam will have sufficient capacity for production at current levels until 2026, Boliden said.
The company’s planned investment totals €33 million, and is conditional upon obtaining official permits. The investment is based on mining until at least 2023, although the company said the new mineral resources may lead it to extend the life of the mine further.
Boliden said the construction of an exploration drift to the new deposit at a cost of €11 million had also been approved.
