Boliden Invests in the Tara Mine

BOLIDEN, Sweden, Jan 11, 2017 /PRNewswire/ --

Successful exploration at the Tara zinc mine in Ireland has identified a new mineralisation with an inferred mineral resource of 10 Mtonnes. Boliden has decided to expand the mine's tailings dam and launch a programme to extend the life-of-mine.

Tara, which is one of the larger zinc mines in the world, accounts for half of Boliden's production of zinc concentrate. Successful exploration has resulted in the discovery of a new mineralisation, Tara Deep, and an extension of the capacity of the tailings dam, which currently limits Tara's lifespan, has been decided. The new tailings dam will have sufficient capacity for production at current levels until 2026. The investment totals EUR 33 m and is conditional upon obtaining the necessary official permits. It is based on mining until 2023, but the new mineral resources offer additional potential. The construction of an exploration drift to the new deposit at a cost of EUR 11 m has also been approved.

"Tara's exploration work in the last few years has been successful, and the capacity of the tailings dam is now limiting the life-of-mine to 2020. New exploration successes, increased productivity, and high zinc prices make extending the mine's lifespan a profitable option, so we have decided to expand the tailings dam with a capacity until 2026," says Mikael Staffas, President Boliden Mines.

The new Tara Deep deposit has inferred mineral resources totalling 10 Mtonnes with a zinc grade of 8.5% and a lead grade of 1.8%. The mineralisation resembles Tara's main ore body, but has a more complicated structure and is at a greater depth of between 1,200 and 1,900 m. In addition to identifying the Tara Deep deposit, successful exploration in the existing mine managed to replace virtually the entire year's production in the mineral reserve.
