Mitsubishi Materials to Cut First-Half Copper Output by 6.8%

April 1 (Bloomberg) -- Mitsubishi Materials Corp. plans to cut copper output by 6.8 percent at its Japanese smelters in the April-to-September period from a year earlier as it takes a maintenance shutdown at its Naoshima smelter.

The Tokyo-based company, Japan’s third-largest copper producer, plans to produce 25,832 metric tons of copper each month in the fiscal first half, compared with monthly output of 27,722 tons in the same period a year earlier, it said in a statement today. The 30-day maintenance shutdown since March has led to a drop in shipments of anode, an intermediate product, to the Onahama smelter in Fukushima from the Naoshima smelter in western Japan, Mitsubishi said.

The company has a 50 percent stake in the Onahama smelter, followed by Dowa Holdings Co. with 31.6 percent and Furukawa Metals & Resources Co. with 12.7 percent. The remainder is owned by other Japanese companies including Mitsubishi Cable Industries Ltd. and Mitsubishi Corp.

The following table details monthly production plans:

(metric tons)

Metal          1st Half 2013     1st Half 2012   2nd Half 2012
               (April-Sept.)    (April-Sept.)   (Oct.-March)
Copper            25,832           27,722          24,839
Lead               2,386            2,513           2,400
Zinc                 786              775             880
Gold   (kg)        2,583            2,765           3,000
Silver (kg)       30,000           30,733          31,833
* Note: The drop in refined lead output is due to supply
tightness in the recycled battery scrap market. Battery scrap is
a main source for refined lead production. The decline in gold
and silver production is due to reduced receipt and reduced
grade of raw materials.
