The ongoing enquiry into illegal mining in Odisha by the members of Shah Commission may get an extension due to huge pile of files and some complexity detected in the mining lease papers.

So far, the commission has checked files of only 32 mining leases, out of the list of 142 leases it had submitted to the government. With the remaining period of their visit, which ends on October 11, it is impossible to verify the documents related to rest of the mines.
