Conventional open-pit mining method along with selective mining techniques will be applied at the Australian vanadium project. The open-pit extends for 3,250m along strike and is proposed to be mined in three stages. The mining sequence will begin with the first stage extending in a 1,100m along strike, which will be divided into 200m-wide benches.

4.1 Process Overview 4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions.
