Development of the Koksai Copper Deposit and Construction of the Concentrating Plant

Project Description: The Koksay project is a large-scale copper mining initiative located in the Zhetysu region of southeastern Kazakhstan, approximately 230 kilometers north of Almaty. It involves the development of one of Kazakhstan’s largest undeveloped copper deposits through open-pit mining. The project includes the construction of a concentrating plant designed to process up to 50 million tonnes of ore annually. The plant will produce copper concentrate and cathode copper as its primary outputs. According to geological estimates, the deposit contains approximately 823.7 million tonnes of ore, with 3.5 million tonnes of copper, 63.7 tonnes of gold, and 865 tonnes of silver. The expected mine life is over 20 years, with an annual output of around 80,000–85,000 tonnes of copper in concentrate equivalent. The project is anticipated to generate significant economic value for the region and country, including the creation of approximately 1,500 jobs during its operational phase. It is being implemented by Konsolidirovannaya Stroitelnaya Gornorudnaya Kompaniya LLP (KSGK), under the parent company Kazakhmys Corporation. In 2018, China Nonferrous Metal Industry’s Foreign Engineering and Construction Company Ltd. (NFC) acquired a 19.4% stake in the project and is involved in technical studies and may contribute to construction. The project has been prioritized by the government of Kazakhstan and is supported at both regional and national levels. Feasibility studies, design, and environmental permitting are ongoing, and full-scale construction is expected to commence in mid-2024.
