Newmont CEO says Goldcorp mines need about 3 years of development, exploration work

Newmont Goldcorp needs to do as much as three years of work at the mines it added through its acquisition of Goldcorp to bring them to acceptable levels of performance, its chief executive told Reuters on Thursday.

The company reported a substantial decline in second-quarter profit, driven largely by the transaction’s integration costs. Shares dropped 3.4% to $37.98 at 1:44 p.m. in New York.
