"We are expecting more revenue once all the 29 mines holders sign the supplementary lease deeds," Mullick said, adding that the state had last year witnessed a fall of 21 per cent in terms of mining revenue.
The state government, which issued notices to 29 mines to reopen their mines after signing supplementary lease deeds, expected generation of above Rs 1,200 crore.
The mines, whose lease period had expired, got the opportunity to reopen under the provision of the new MMDR (Amendment) Act, 2015, officials said.
Among the mine owners who have signed the lease deeds to restart operations are KJS Ahluwalia, KN Ram and Co, KP Enterprises, Rungta Mines, Odisha Manganese & Minerals Ltd (OMM), Tata Steel and Aryan Mining & Trading Corporation Ltd (AMTC).
Meanwhile, since the Supreme Court is yet to hear cases of some mines, involved in excess mining and violation of Forest and Environment Act as reported by Shah Commission, the state government has clarified in the lease agreement that it will do as directed by the apex court, they said.
