Mitsubishi Materials to Raise Second-Half Copper Output

Mitsubishi Materials Corp., (5711) Japan’s third-largest copper producer, said it will increase output by 1.6 percent at its Japanese smelters in the October-to-March period compared with a year earlier.

The Tokyo-based company plans to produce 26,312 metric tons of copper a month, compared with monthly output of 25,903 tons in the same period a year earlier, it said in a statement today.

The following table details monthly production plans:

(metric tons)
Metal          2nd Half 2013     2nd Half 2012   1st Half 2013
               (Oct.-March)      (Oct.-March)    (April-Sept.)
Copper            26,312           25,903          25,832
Lead               2,480            2,504           2,386
Zinc                 657              897             786
Gold   (kg)        3,033            2,500           2,583
Silver (kg)       31,333           27,503          30,000
* Note: The drop in refined lead output is due to tight supply
in the recycled battery scrap market. Battery scrap is a major
source for refined lead production. The increase in gold
and silver production is due to a higher grade of raw materials.
