Total refined copper production will increase approximately 10% year-on-year. Production will increase approximately 5% at Naoshima Smelter & Refinery, approximately 20% at Onahama Smelter & Refinery respectively.
Refined gold and silver production will decrease mainly due to the lower grade of Gresik slime.
