Construction of the mine began in 1978 on the basis of the Almaz-Zhemchuzhina, Millionnoye, Pervomayskoye and No. 21 deposits. Previously, the mine was called "Central". In 1999, the first stage of the mine's first start-up complex with a capacity of 100,000 tons of ore per year was commissioned. In 2001, the full capacity of the first stage was commissioned for 2 million tons of ore per year. In connection with the anniversary of the Republic of Kazakhstan, it was renamed the 10th Anniversary of Independence of Kazakhstan mine.
The construction of the second stage is currently being completed. The unique facility includes two deposits, as well as six underground horizons, one of which, minus 480, is considered one of the deepest in the world. There is also the deepest mine shaft in Kazakhstan – more than a kilometer underground.
The design capacity of modern production exceeds 7 million tons of ore per year. New, high-performance mining systems using the most advanced self-propelled machinery will be used for ore mining. High technical equipment will significantly reduce manual labor and increase the productivity of each miner, and an intelligent underground positioning system for determining the location of personnel and equipment will ensure their safety.
The launch of a new mine is strategically important not only for the stable operation of ferroalloy plants, but also for the single-industry town of Khromtau, where DGOC is a city-forming enterprise. 1,000 jobs will be created. ERG is investing 1,031 billion tenge in the construction of the mine.
