Deposit Type

  • Orogenic
  • Vein / narrow vein


Summary:

The Fosterville Goldfield is located within the Bendigo Structural Zone in the Lachlan Fold Belt. The deposit is hosted by an interbedded turbidite sequence of sandstones, siltstones and shales. This sequence has been metamorphosed to sub-greenschist facies and folded into a set of upright, open to closed folds. Mineralization at Fosterville is controlled by late brittle faulting. These faults are generally steeply west-dipping reverse faults with a series of moderately west-dipping reverse splay faults formed in the footwall of the main fault. There are also moderately east-dipping faults which have become more significant footwall to the anticlinal offsets along the west dipping faults. Primary gold mineralization occurs as disseminated arsenopyrite and pyrite forming as a selvage to veins in a quartz-carbonate veinlet stockwork. The mineralization is structurally controlled with highgrade zones localized by the geometric relationship between bedding and faulting. Mineralized shoots are typically 4 to 15 metres thick, 50 to 150 metres up/down dip and 300 to 1,500 metres down plunge, and have average grades of 5 to 10 g/t gold, with individual assays up to 60 g/t gold. Primary gold at Fosterville also occurs as visible gold that variably overprints sulphide mineralization and is found as disseminated fine specks of gold within host quartz veins. The visible gold is spatially associated with antimony mineralization in the form of stibnite that occurs with quartz and varies ........


Mining Methods

  • Open stoping
  • Cemented backfill
  • Paste backfill


Summary:

Mining activities at Fosterville are currently focused on the Central, Phoenix and Harrier underground ore zones. All areas are extracted using open stoping techniques with the application of Cemented Rock Fill where practical. Selection of the specific mining method within the open stoping regime is based upon previous experience at the Fosterville mine and expectations of ore zone geometry and geotechnical conditions. In 2020, work on a twin exploration drive, capable of supporting production activities, commenced to connect the existing Fosterville mine to Robbin’s Hill, which is expected to be established as a second mining operation to feed the Fosterville mill over the next few years. The twin drive had advanced over 7,800 metres as at December 31, 2021 and remains on track for completion in mid-2022. Underground mining is conducted using a conventional fleet including jumbos, production drills, loaders, trucks and ancillary equipment. Open Cut mining (when required) is conducted using a conventional fleet including excavators and trucks with a contract mining fleet and workforce. The Phoenix to 4240mRL, Harrier below 4500mRL, Central and Robin orebodies are accessed from a footwall decline position while the Phoenix below 4240mRL and Harrier orebody above 4500mRL are accessed from the hangingwall. All areas are planned to be extracted using open stoping techniques, primarily in a top down sequence, with the application of cemented rock fill or paste fill where applic ........
