Deposit Type

  • Orogenic
  • Vein / narrow vein


Summary:

Vivien is a typical orogenic structurally controlled Archaean gold lode system.

Mineralisation occurs within a high-grade quartz vein, hosted by a dolerite-gabbro unit. The veins trend 028° magnetic and dips steeply (70°) to the SE. The quartz vein/lode averages 2.7m width and has significant strike and dip continuity (˜500m). The high-grade zones are generally wider and sulphide rich, with pyrrhotite and arsenopyrite being the dominant sulphide species. Mineralisation is related to a secondary phase of quartz veining with associated sulphide mineralisation.


Mining Methods

  • Sub-level open stoping (SLOS)
  • Longhole stoping
  • Cemented backfill


Summary:

Vivien is a high-grade quartz lode deposit, located near Leinster. Mining commenced in 2015 and Vivien has been a steady contributor with ore trucked to the Mt Magnet mill.

UG deposit Vivien is mined by conventional sub-level open stoping methods and a conventional, narrow, top-down, long hole stoping method, with partial backfilling.

An underground drill programme was completed during the year with the potential below the current deepest level (-020mRL) appearing to reduce the likelihood of deeper extensions to Vivien as the vein narrowed and reduced in grade. Mining focussed on effective extraction of the remaining reserves and any remnant resource areas.

Mining studies are in progress for a potential cutback of the historic Vivien open pit to access a mainly oxidised lode between the pit base and top of the underground mine.

RUC is engaged at the Vivien Underground mine as the full mine service contractor for production and development. RUC has assisted Ramelius (the Client) to progress the mine with an additional eight production levels completed. RUC has been successful to mine to new depths at Vivien with operational professionalism that was also delivered safe as ever.

- Capital and Operational development and ground support;
- Production Drill and Blast;
- All material handling to surface;
