It means the state-owned company can mine bauxite in Gudem and Katamraju Konda in Andhra Pradesh.
There is an estimated 85Mt of bauxite reserves at the two sites. Nalco plans to build an INR60bn ($1.29bn) 1.4Mt greenfield alumina refinery at Visakhapatnam to process the bauxite from both sites.
Nalco has also signed an MOU with state-owned Industrial Infrastructure Development Corporation to build an aluminium site in Angul.
The jointly owned site will cost about INR750M ($16.2M) and both companies will have an equal stake in the project. The companies said the site will help towards development of an important industrial cluster and downstream industries.
