Glencore to sell part of silver output to repay debt

Zurich

DEBT-LADEN mining and commodities giant Glencore is selling a share of its future silver output to help reduce its towering debt, as its copper production has taken a hit.

Glencore, one of the world's largest miners and producers of copper, said on Wednesday that its copper production had slumped 2 per cent over the past nine months to 1,127,500 tonnes.
