(1) Notwithstanding anything contained in section 10, the Central Government may, if it is satisfied that a Government company is willing to comply, or has complied, with such terms and conditions as the Central Government may think fit to impose, direct, by order in writing, that the land or the rights in or over the land, as the case may be, shall, instead of vesting in the Central Government under section 10 or continuing to so vest, vest in the Government company either on the date of publication of the declaration or on such other date as may be specified in the direction.
     (2) Where the rights under any mining lease acquired under this Act vest in a Government company under sub-section (1), the Government company shall, on and from the date of such vesting, be deemed to have become the lessee of the State Government as if a mining lease under the Mineral Concession Rules had been granted by the State Government to the Government company, the period thereof being the entire period for which such a lease could have been granted by the State Government under those rules; and all the rights and liabilities of the Central Government in relation to the lease or the land covered by it shall, on and from the date of such vesting, be deemed to have become the rights and liabilities of the Government company.
