It is proposed to mine the Southdown Magnetite deposit using proven open pit mining methods with the magnetite mineralisation being crushed, ground, screened and then magnetically separated to produce a magnetite concentrate. Tailings will be disposed in a tailings storage facility and overburden is to be placed in waste rock dumps.
Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clearcutting or burning of vegetation above the ore deposit may precede removal of the overburden.
Mining at Solomon Hub occurs at multiple, spatially separate pits, each working multiple faces simultaneously, and hydraulic excavators are employed to dig the material from working mine faces. After the overburden is removed, the iron ore and internal waste are extracted.
