The blocks include three lime mud zones, three for construction sand, and seven rich in polymetallic nodules. Initially set to close on 27 February, the bid deadline was first extended to two April and now to one May following requests from interested companies seeking more time to evaluate the areas.

A ministry source said the extension is aimed at ensuring wider industry participation. Meanwhile, opposition parties have raised concerns over potential environmental damage. Protests have also emerged in Kerala, led by local fishermen.

The mines ministry stated it consulted the environment and fisheries departments before launching the auction. Despite limited expertise in seabed mining, Indian firms are reportedly seeking help from international players like Dutch shipbuilder Royal IHC.

India sees this auction as crucial to securing raw materials for its energy transition goals, including adding 500 gigawatts of renewable energy capacity by 2030.
