Following several representations against auction of tungsten block in Nayakkarpatti in Tamil Nadu‘s Madurai, Union ministry of mines Tuesday said it has asked Geological Survey of India to re-examine the block and explore the possibility of redefining its boundaries, excluding a bio-diversity site. It asked the state govt to keep the process of issuing ‘Letter of Intent’ to the preferred bidder on hold for the time being.
