The government plans to auction three mineral blocks having reserves of 280.295 million tonne in the current and next month. Of the mines to be auctioned, two are limestone blocks while one is graphite mine, according to latest data of mines ministry. The limestone blocks in Chhattisgarh will go under the hammer on February 8 and February 11, while the graphite block in Jharkhand will be auctioned on March 2. The notice inviting tender (NIT) of both the limestone blocks was out on October 6 last year, while in the case of graphite block the tender was out on December 25. All the three blocks have no end-use reservation, the ministry said. The Centre had earlier said it was considering granting all approvals, including environmental clearance, to mineral blocks before putting them up for sale, a move that may give a push to the auctions. The idea is to fast-track auctioning and that issues related to green clearances and land rights are addressed upfront.
