for qld , at least 12 monthes, leases can take a while 1 to 2 years or more at times just look at other qld coal companies reports to see how long some have been waiting,no idea of the process and how they select the order of what get granted
look at the dates of the annoucment the bunch of leases that are granted where lodged in early march 2010 , granted in late march 2011 but one has not been granted yet even tho they were all applied for on the same day.
kingsgate had to wait 7 years for a mineral lease.
