ShapshotFederation Project is one of the highest-grade base metal development projects in Australia. The Federation deposit hosts high-grade zinc, lead, and gold mineralisation and remains open at depth.

On 10 October 2022, the Federation Mine Feasibility Study was released. In April 2023, the Aurelia Metals provided an update, which further refined the Feasibility Study and delivered an improved path to production, lower capital expenditure, along with an updated mine design to increase operational efficiency.

Project development will involve the underground mining of the Federation deposit for treatment through established processing circuits at Peak and Hera sites.

The Federation Project is currently under construction with development ore expected in 2024.

Deposit type

  • Breccia pipe / Stockwork
  • Vein / narrow vein

Summary:

The Federation deposit is located on the eastern margin of the Palaeozoic Cobar Basin, an intracratonic basin within the Lachlan Orogen. Mineralisation at Federation is epigenetic and structurally controlled with several steeply dipping vein breccia/massive sulphide lenses developed in the centre of a broad northeast-southwest striking corridor of quartz–sulphide vein stockwork mineralisation. The mineralisation is hosted by fine-grained sedimentary rocks and is best developed within open upright anticline closures in areas of strong rheology contrast imposed by early stratiform alteration.

Massive sulphide and sulphide breccia base metal mineralisation is typically zinc-rich and associated with intense cross-cutting black chlorite alteration in the lower parts of the known deposit, with silica-sulphide dominant infill in the upper parts. Late bedding-parallel faults have been identified that may have caused some brittle offset within the system. These structures possibly started as extensional faults and could have focused hydrothermal fluids during alteration and mineralisation.
