Mine Life2030
The new mine projects at Budgerygar and Avoca Tank will replace production from the Tritton and Murrawombie mines as they wind down over the next couple of years. Budgerygar and Avoca Tank mines will extend the life of the operation as well as increase mined copper grade.

Production from the new mine projects at the Budgerygar and Avoca Tank deposits are scheduled to ramp-up during the financial year ended 30 June 2023 and will extend the life of Tritton as well as materially increase copper head grade.

Deposit Type

  • VMS


Summary:

The Tritton underground mine has been the primary source of ore feed for the processing plant (Tritton Mill) and from 2016, the Murrawombie underground mine has been the supplemental ore source. New mine projects: • Budgerygar deposit – an extension of the Tritton underground mine; • Avoca Tank underground mine; and • Maiden mineral resource estimate at the Constellation deposit. Tritton Deposit The Tritton deposit is a sulphide copper mineralised body located on ML1544 in central New South Wales (NSW), Australia. The deposit geology is best described as a structurally controlled sulphide deposit. Copper mineralisation, in the form of chalcopyrite is associated with a late-stage regional deformational event. Sulphide mineralisation within the Tritton tenement package has been classified as either a structurally controlled epigenetic sulphide system or a stratiform “Besshi style” volcanogenic massive sulphide (VMS) deposit. Recent geological investigations at both the Tritton and Murrawombie deposits have identified a sulphide mineralisation occurring late in the structural deformation events. There is decreasing support for the VMS model of deposit formation as we can better undertsnading of the deposits. Sulphide mineralisation is dominated by massive, banded and stringer pyrite +/- chalcopyrite, with a relatively consistent massive pyrite – chalcopyrite unit along the hanging wall contact. Alteration assemblages adjacent to mineralisation are characterized by an an ........


Mining Methods

  • Sub-level open stoping (SLOS)
  • Bench stoping
  • Transverse open stoping
  • Cemented backfill


Summary:

The mining method assumed in the Ore Reserve estimate varies with the deposit. At the Tritton deposit, the method is sub-level open stoping with cemented paste fill. At the Murrawombie deposit, the ore is extracted using underground bench stopes and small open stopes with cemented rockfill. Future mining of the shallow remnant portion of the Murrawombie deposit will be by open pit, as the final extraction stage. The yet to be developed Avoca Tank deposit project is planned to use up-hole benching with dry rock fill. Avoca Tank Deposit The Avoca Tank deposit is a high-grade copper-gold deposit located 5km to the north of the existing Murrawombie underground mine. The development of the access decline to Avoca Tank commenced in mid-October 2021 and by end of the financial year was approximately 70% complete. The decline starts from a portal which was reviously used to access the North-East and Larsens mines. First production ore from Avoca Tank is scheduled for Q4 2023. The mining method to be applied at Avoca Tank, as described in the pre-feasibility study, is underground sub level open stoping. In the upper and middle production blocks of the mine stopes will be mined as single benches between 20m high sub levels. In the lower production block the stopes will be mined over several sub levels in a single stope. Access to the ore will be from a spiral decline mined by conventional drill and blast methods. The decline and sub level access drives will be mined 5.5m high by 5 ........

Reserves at June 30, 2022:
Tritton Operation Mineral Resource figures are reported at a range of copper cut-off grades between 0.3% to 0.9%, depending on the deposit and mining method. Copper grade cut-offs are applied on a block by block basis.

Tritton Operation Ore Reserve estimates are reported at a range of copper cut-off grades between 1.18% to 1.15% copper depending on the deposit and mining method.
