Major Mines Projects
In the expansion area LP2 (Lombador Phase 2) the mining method used for mining zinc ores is optimised bench and fill (OBF) as per LP1. The development of the Lombador decline ramp provided access for further geological drilling of deeper areas of the resource, which identified further extensions to the Lombador orebody.
