Ann: Becoming a substantial holder, page-4

Southern Copper (SCCO +1.4%), one of the world's largest copper companies, says the market probably will not see new supply for another 8-10 years.Prices already are well above the incentive level for new projects that would help ease the supply squeeze, but it can take twice as long to build mines now than in the past, Southern Copper CFO Raul Jacob tells Bloomberg.
The next generation of copper mines must contend with lower ore quality that can push up costs while adhering to higher environmental and social standards, which the CFO says is part of the reason Southern Copper will not be accelerating its expansion plans to tap higher prices.
