  • Geology
    The gold mineralisation occurs in steeply dipping low sulphidation epithermal fissure quartz veins. High-grade gold mineralisation defined in the project resources occurs within five deposits (Royal Shoot, Crown Shoot, Sovereign Shoot, Klondyke North and Kilkenny Shoot), each developed at the intersection of major structures.

    The Royal extends over a strike length of approximately 350 metres, the Crown is approximately 300 metres in strike length and the Sovereign has a strike length of 150 metres. The ore bodies average approximately 5 metres in width.
  • Mining
    Underground mining is carried out by a mining contractor, managed by Evolution. The underground orebodies are accessed from a decline and the open stoping mining method is used with concurrent waste backfilling.
  • Processing
    Ore is free milling and is treated on site by conventional crush-grind-CIP processing to produce gold-silver- dore. The processing plant was upgraded from 450ktpa to 550ktpa in 2011.
