Hera Project

Aurelia Metals (AMI) commenced the Hera underground mine development in January 2013 and full scale development of the Hera Project in March 2013, following completion of a major A$158m funding transaction with Glencore International (‘Glencore’).


The Hera project has received all required approvals for construction and operation. Key approvals include:

  • Major Project Approval – Issued by the NSW Dept of Planning and Infrastructure in August 2012
  • Environmental Protection Licence – Issued by the EPA in March 2013
  • Mining Lease – issued by NSW Trade and Investment in May 2013


Surface earthworks construction is being completed under contract with Neill’s Earthmoving of Nyngan, NSW. Major earthmoving projects include:

  • Site access road and boxcut (stage 1 completed)
  • Water catchment dams and sediment basins
  • 3 stage Tailings Storage Facility (TSF)


The Hera Project Process Plant will be constructed under a EPC (Engineering, Procurement and Construction) Contract with Gekko Systems of Ballarat, Victoria. AMI has been working closely with Gekko on the flow sheet development and plant design since the Hera Definitive Feasibility Study. The EPC Contract is a lump sum, turnkey contract for the construction of the process plant, operating to agreed performance warranties.

The process plant is comprised if the following key components:

  • Primary and secondary crushing
  • Milling
  • Gravity gold circuit
  • Rougher flotation
  • Regrind
  • Leach circuit and Merrill Crowe
  • Cleaner flotation

Once complete the plant will produce gold doré and a bulk lead-zinc concentrate for sale.


The Hera underground mine development is proceeding under a mining contract with Pybar Mining Services (‘Pybar’) based in Orange NSW. At 31 May 2013, the total underground advance stood at 674m representing 91% of project schedule.

The mine will use the sub-level bench stoping method to operate at a peak production rate of 350,000 tonnes per annum.


Construction is underway for the Hera Accommodation Camp. The camp is being constructed in two stages, each stage for 40 rooms. Stage 1 is scheduled for occupation in August 2013.
