Building its own resource base is one of RUSAL's most important competitive advantages. The Company has its own capacities and sources of raw materials throughout the entire aluminium production chain, including the entire bauxite supply. One of the largest projects to increase the Company's own production of bauxites was the commissioning of the Dian Dian deposit in Guinea with a capacity of 3 million tonnes per year. 

In 2018, as part of the first phase, in addition to commissioning the mine, all the associated ore transportation and storage infrastructure (including roads and a railway line) was built. 

Dian Dian is the largest bauxite deposit in the world with proven reserves of 564 million tonnes. The right to develop it belongs to RUSAL.
