Field Trip

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

25th September

* You must have registered for the field trip to be able to attend field trip.


This field trip is designed to examine aspects of the geology and mineral systems of the Lachlan Orogen, as part of Discoveries in the Tasmanides Conference in Wagga Wagga. In particular, the field trip is focussed on:

  • Early Silurian epithermal and porphyry systems
  • Early Devonian intrusion-related tin (± tungsten) systems

The field trip will combine new work by the GSNSW - including the East Riverina Mapping Project (ERIV) and mineral systems studies – with known mineralisation and recent exploration activity by Australian Tin Resources, Thomson Resources, Sandfire Resources and New South Resources.


The trip leaders are Phil Gilmore, Phil Blevin (ph 0403 157 491) and John Greenfield (ph 0427 943 909).


Meet at 7.30 am in front of Wagga Wagga RSL for a 7.45 am departure. There should be two big Priest buses at the bus stop there.


Field clothing - steel-capped boots, workwear, water. The weather will be cool in the morning so bring warm clothes, and of course a rain jacket just in case (actually it would be great for the region if we got rained on all day).


You will be given a bag with morning and afternoon tea (lunch will be provided at Temora). We will have extra snacks, water and sunscreen available. You will also be given a hard-hat and vest for the Ardlethan mine site.


The field trip will visit locations on mine sites and along roads, so please adhere to the following guidelines:

  • Always follow the instructions of the field trip leaders and the bus drivers.
  • Please where appropriate Personal Protective Equipment (PPE) when instructed.
  • Do not walk away from the group.
  • Field trip guides and geological staff are trained first aiders. First aid kits will be in GSNSW vehicles.
  • Be aware of environmental factors – such as uneven ground, traffic, old mine workings, wildlife including snakes and weather conditions.
  • Please respect landholders – permission should always be granted prior to accessing private land.
  • At Ardlethan – do not take hammers off the bus, or break rock samples as this poses a risk to others.
