The Dairi lead-zinc mine project, located in the northwestern part of Sumatra, Indonesia, is a world-class, high-grade lead-zinc deposit that has yet to be developed. It contains lead and zinc metal resources of approximately 3.58 million tonnes. Currently under construction, the project is designed with an annual ore processing capacity of 1 million tonnes. Once completed, it is expected to become a globally significant lead and zinc production base and help ease supply pressures for these metals in China.
