The National Institute of Ocean Technology (NIOT) has started exploratory trials in the Andaman Sea using Varaha-3, a specialized seabed mining machine. The work is being carried out at a depth of 1,193 meters. The Geological Survey of India had previously flagged the trial areas as potential hotspots for valuable mineral resources, including polymetallic nodules.
Varaha-3 trials and targeted mineral resources
The trials form part of India’s broader approach to exploring and harnessing ocean resources. Varaha-3 is being used to conduct seabed mining tests in the Andaman Sea. The Geological Survey of India’s earlier identification of these locations focused on the presence of polymetallic nodules.
Polymetallic nodules recovered during the trials
During the trial operations, Varaha-3 collected polymetallic nodules sized between 60 and 120 mm. The recovered nodules contain metals including nickel, cobalt, and copper. These metals are relevant to industries such as renewable energy and electric vehicle production.
Deep Ocean Mission technology and integrated mining system
Varaha-3 is designed to emphasize operational efficiency while minimizing environmental impact. The initiative aligns with India’s Deep Ocean Mission, under which the government has invested in advanced deep-sea exploration technology. This includes an integrated mining system intended to optimize extraction and transportation of nodules.
