Investigation Division

Investigation refers to Mineral Exploration. The word "Investigation" has historical significance. In early sixties NMDC had the task to investigate the known mineral occurrences in the country which could be commercially exploited. And the name continues. In the process NMDC thusfar, proved many mineral deposits in the country and abroad. Few of the important investigations done are
