Feasibility study and engineering and project management

The Lady Annie Copper Project, located 137km north of Mt Isa, is a large, medium grade, oxide copper resource.  The Project is a 2.6 Mtpa copper heap leaching operation comprising crushing, agglomeration, stacking, heap leaching, solvent extraction, and electrowinning (SXEW) to produce 19,000 tpa of LME A Grade copper cathode.

We were responsible for the feasibility study for the project and then performed engineering and project management services on an EPCM basis for the project infrastructure and the heap leach - SXEW plant and associated facilities.

Project Highlights

• Excellent safety record with over 465,000 man-hours worked
• Peak construction workforce of 320
• Relocation and upgrade of the Mt Gordon SXEW plant to Mt Kelly
• LME A Grade copper cathode produced at full design production rates in the first week of operation
• Completion of a 52km infrastructure corridor containing a 66kV HV power line and raw water pipeline over rough terrain from Mt Gordon to the Mt Kelly site.
