Toho Zinc Co., Japan's third-biggest producer of the metal, will restore full capacity at its Rasp mine in Australia around the middle of this year after improving access to high-grade ore deposits.
Production of zinc concentrate at the site in New South Wales will rise 15 percent from a year earlier to as much as 46,000 metric tons in 2015, said Toshio Shimamura, general manager and executive officer at Tokyo-based Toho's mineral resources business division.
The company reduced operating rates to 70 percent in October 2013.
