Glencore third quarter zinc output up 13 percent

Glencore third quarter zinc production rose 13 percent from the previous quarter, the first time quarterly output has increased since the group announced sweeping mine suspensions to boost prices, a production report showed on Thursday. Some metal investors have worried that the reversal of Glencore's output cuts would dampen a rally in zinc, the top performer among base metals with gains of over 50 percent so far this year.
Investors have piled into the market on expectations of severe shortages emerging due to the Glencore suspensions as well as major mines such as Century in Australia running out of ore and closing down. Glencore has declined to say when it plans to fully resume production at mines it had mothballed in an effort to boost prices, which hit multi-year lows in January.
