The Company & Why Join
Join a globally recognised underground mining principal with a solid safety-first culture and a genuine track record of developing long-term careers.
This role puts you at a well-established, high-producing underground hard rock mine in North QLD with an estimated mine life of 20+ years, processing ore through crushing, grinding and differential flotation to produce zinc and lead concentrates.
You'll work within a close-knit fixed plant maintenance crew and have genuine potential to move onto the principal's own books as roles become available.
About the Role
You'll be based on surface, working within the mill and fixed plant across the full processing circuit - crushing and grinding (SAG/ball mills), differential flotation, and concentrate thickening and filtration.
Duties include:
Electrical
Installation, maintenance and fault-finding on motors, switchboards, MCCs, VSDs, transformers and HV/LV reticulation
HV work on large mill and crusher motors, thickener drives and flotation cell drives
Preventative maintenance including thermal imaging, insulation testing and switchgear servicing

Managing dust and hazardous area considerations specific to base metals plants, where corrosive, conductive concentrate dust can build up on electrical equipment
Standby power and emergency systems maintenance
Instrumentation
Calibration of process instrumentation
Flotation-specific instrumentation - froth depth/level control, air flow to cells, and reagent dosing control for differential lead-zinc separation
Density and pulp level instrumentation across grinding, flotation and thickening
Online analysers - particle size and on-stream analysers for real-time grade monitoring
Concentrate handling instrumentation - belt scales, moisture analysers and load cells for thickening, filtration and load-out
PLC/SCADA/DCS troubleshooting, working closely with metallurgists to keep flotation bank control loops tuned and reliable
For those ticketed, there's also scope for 11kV reticulation, substation maintenance and HV switching work.
