Korea Zinc announced on June 5 that its Australian subsidiary Ark Energy has secured grid connection approval for the Richmond Valley solar and ESS project. The Richmond Valley project involves building a 2,200 MWh ESS and a 200 MW solar power plant in the Richmond Valley region of New South Wales, Australia.

Korea Zinc announced on May 6 that its consolidated operating profit for the first quarter was preliminarily estimated at KRW 746.1 billion, up 175.2% from a year earlier. Revenue for the quarter rose 58.4% year on year to KRW 6.072 trillion, while net profit increased 117.9% to KRW 354.0 billion.

South Korea’s Korea Zinc plans to invest $6.6 billion to develop a major critical minerals smelter and U.S. headquarters in Tennessee, marking the state’s largest-ever private investment. The project will span Clarksville and Gordonsville, including a new manufacturing facility and the reopening of a former mine. The integrated smelter will produce 13 nonferrous metals such as zinc, copper, and lead, supporting key industries including defense, aerospace, and automotive. The project is expected to create over 740 jobs and reduce U.S. reliance on China for critical minerals. Developed in partnership with the U.S. government, which may take a 40% stake, construction is scheduled to begin in 2027, with site preparation starting in 2026.

On April 2, Nyrstar announced that the sale of its US assets to Korea Zinc was completed on April 1. The assets involved included the East Tennessee and Mid Tennessee mining complexes as well as the Clarksville smelter. The transaction, first announced in December 2025, had received all necessary regulatory and government approvals. Assets and employees were transferred to Korea Zinc under existing terms, ensuring a seamless transition in operations, safety standards, and production. Under the terms of the agreement, Trafigura will continue to market and sell the Clarksville smelter’s total production of zinc metal and supply concentrate and oxide to the operation throughout 2026.

Korea Zinc is in talks with major U.S. technology companies to recover valuable metals from data-center electronic waste. The initiative aims to extract multiple metals including copper and other strategic materials. Analysts say the project reflects the growing importance of electronic waste recycling in global metal supply chains.
