Field Trip

One day field trip – Geology and Mineralisation of the East Riverina

25th September

Led by Phil Gilmore and Phil Blevin (Geological Survey of NSW), plus exploration/mining reps (TBA)

Join us on a one-day field trip which will highlight recent regional mapping and mineral systems studies by the Geological Survey of NSW, and current exploration programs in the East Riverina project area. The field trip will visit key outcrops and structural features through the region, highlighting the updated mapping and understanding of the region's geology. Mineral systems and exploration programs to be examined will include porphyry Cu-Au in the Junee-Narromine Belt of the Macquarie Igneous Province and magmatic Hydrothermal Sn(-W) in the Wagga Tin Belt.

We are planning on visiting exploration programs from one or more of each of the follow mineral systems:

  • Porphyry Cu-Au at West Wyalong (Argent), greater Gidginbung (Sandfire), Dobryode (New South Resources).
  • Magmatic Hydrothermal Sn at Ardlethan mine and/or Bygoo (Thomson Resources)
  • Orogenic gold (Barmedman)
Key outcrops
  • Junee-Narromine Belt and Junawarra Volcanics
  • ~430 Ma S-type granite
  • ~418 to 412 Ma granite and volcanic rocks
  • Silurian-Devonian basins
  • Gilmore Fault Zone

AM depart from Wagga Wagga 1. ~430 Ma granite 2. ~415 Ma granite 3. ~415 Ma volcanic rocks 4. Ardlethan 5. Bygoo.

PM 6. West Wyalong / Gidginbung 7. Barmedman (Sil-Dev basins) 8. Temora 9. Junee 10. Wantabadgery/Eurongilly (Gilmore Fault Zone, turbidite) – Wagga Wagga.
