Mining Act 1992

The validity of a consolidated mining lease is not affected—

by the failure of any person to comply with this Act or the regulations in relation to the grant, renewal or transfer of an existing lease that has been consolidated, or

by the inclusion in the area of land over which the consolidated mining lease has been granted of any land not subject to an existing lease.

The Minister may amend a consolidated mining lease so as to exclude from the area of land the subject of the lease—

any area of land the subject of an existing lease that appears to the Minister not to have been validly granted, renewed or transferred, and

any area of land that appears to the Minister not to have been subject to an existing lease.

An amendment takes effect on the date on which written notice of the amendment is served on the holder of the consolidated mining lease or on such later date as may be specified in the notice.
