"It's time to stop building," Glencore's (GLCNF.PK) Ivan Glasenberg says in berating mining CEOs for the glut of new mines that has whacked profits. Stalling investment in new mines will mean "we will be late to invest. So, who cares? We’ll be late and we’ll have to invest in five years’ time. It’ll take us three years to build the mine but we could hopefully have an eight-year run."
