Congo allows Zijin mine to resume operations, ministry letter says

China's top copper smelters have proposed to cut production by 5% to 10%, according to Reuters.

Indonesia's export ban takes effect from June in an effort to force miners to invest in domestic smelting facilities.

Shrinking margins haven’t deterred Jiangxi, which plans to increase refined copper output this year by 11% to 2.32 million tons.

It expects to produce 100,000-120,000 oz. of gold from its Tujuh Bukit mine and 14,000-16,000 tonnes of copper from its Wetar mine.

A partnership between the two miners began late last year.

Local residents reported a lack of clean drinking water.

Fund managers have rushed to buy copper after the price broke up out of its one-year trading range earlier this month.

Under the agreement, initial production from Crean Hill would be shipped to Vale's Clarabelle mill in Sudbury for processing.

The production will be supported by high-grade ore from Phase 7 at its Batu Hijau mine.
