The Goa government has received 28 bids for leases of four iron ore blocks that were put up for auction. Goa’s Director of Mines & Geology Mr Suresh Shanbhogue said “We opened the technical bids, checked how many physical submissions we have received, and whether they have done online submission or not. The physical submission number and the online submission number should match. We did this in the presence of the bidders. We have received 28 bids both online and offline. The technical documents will now be scrutinized to check whether they have net worth certificate, etc, and that process has begun.”Of the four blocks up for auction, three are in North Goa at Monte de Sirigao, Sirigao-Mayem and Bicholim, previously owned by Rajaram Bandekar, Chowgule & Co and Sesa Mining Corporation, while the fourth is in South Goa’s Kalay, previously owned by NS Narvekar. These mines have cumulative estimated reserve of about 135 million tonnes of low-grade iron ore resource.
