Preliminary list of field trips (may be subject to change) 

New Zealand

Orogenic and placer gold deposits of the South Island

This field trip provides an overview of the geological setting of orogenic and placer gold deposits in the South Island. Visits will be made to historic sites, and active mines and prospects including Macraes that is mined by open-pit and underground methods producing approximately 180,000 oz of gold annually, with more than 5 Moz gold produced since 1990. The itinerary transects the South Island from Christchurch to Greymouth on the West Coast, then heads south to Haast and crosses the Southern Alps to Hawea and after three days in Otago, finishes in Dunedin. The trip will feature fantastic alpine and coastal scenery and some of New Zealand’s most famous tourist locations making it highly suitable for accompanying persons.

Timing: Pre-conference
Start: Christchurch, Saturday 6 November
Finish: Dunedin, Friday 12 November
Duration: 7 days and 6 nights


Macraes open pit gold mine (orogenic Au), Otago

Epithermal environments of the North Island 

This field trip provides an overview of the volcanic-tectonic setting, hydrology, fluid chemistry, alteration and mineralisation of sub-aerial hydrothermal systems and their energy and mineral resources. The itinerary includes visits to active volcanoes (Tongariro Volcanic Centre), active geothermal systems (Waiotapu, Orakeikorako, Waimangu, Wairakei, Rotorua) and epithermal gold-silver deposits in the Coromandel Peninsula (Waihi and Karangahake).

Timing: Post-conference
Start: Rotorua, Saturday 20 November
Finish: Auckland, Wednesday 24 November
Duration: 5 days and 4 nights


Champagne Pool, Waiotapu thermal park

Volcanic features of the Rotorua District 

A 1-day tour of the volcanic and geothermal features of the district including the Rotorua and Okataina calderas.


Volcanic features of the Taupo Volcanic Zone

A 2-day tour of rhyolitic and andesitic volcanic features of the region


Lakes Okataina, Rotoma and Rotoiti

Australia

Arc- and orogenic-associated mineral systems in Victoria, Australia 

This trip will explore Cambrian-aged porphyry-style mineralisation that developed along the eastern margin of Gondwana in the Grampians-Stavely Zone and world-class gold mineralisation in the Bendigo and Stawell Zones. Emphasis will be placed on new developments in understanding the larger-scale geodynamic context of these mineral systems through visiting key outcrop, underground mine visits (likely at Fosterville, Stawell, and Costerfield), and drill core viewing.


Timing: Pre-conference
Start: Melbourne, Monday 8 November
Finish: Melbourne, Friday 12 November
Duration: 5 days and 4 nights


Underground exposure of a gold-bearing orogenic quartz
vein system, Victoria

Metallogenic evolution of the Yilgarn Craton, Western Australia

The Yilgarn Craton has long been recognised as having world class Au and Ni endowment. Yet the endowment varies dramatically between terranes of the Yilgarn and between constituent geological domains, showing a tendency to cluster in districts or ‘camps’. The one-week excursion will visit classic geological localities of both nickel and gold deposits from the Yilgarn Craton showcasing the deposit style diversity and focusing on Ni and Au mineral system formation from regional to deposit scales.


Timing: Pre-conference
Start: Kalgoorlie, Saturday 6 November
Finish: Kalgoorlie, Friday 12 November
Duration: 5 days and 4 nights

VHMS and Sn deposits of Western Tasmania: from exploration to remediation  

Western Tasmania has undergone three major metallogenic episodes that have resulted in the formation of many significant base metal and tin deposits within a small (~100-km-long) region. The major geologic feature that hosts the copper, gold, and base metal deposits is the Cambrian submarine Mt Read Volcanic belt, whereas the tin deposits mainly formed where Devonian to Carboniferous granites intruded basement carbonate sequences, producing proximal and distal skarns. The field trip will provide the opportunity to visit several of the well studied Cambrian VHMS and Devonian granite-related deposits (e.g. Hellyer, Mt Lyell , Henty and Rosebery-Hercules VHMS, Renison Sn and Kara Fe-W skarn – to be confirmed by host companies). The field trip will also focus on the environmental legacy of mining and remediation strategies that have been adopted in the past, present and future.


Timing: Post-conference
Start: Hobart, Saturday 20 November
Finish: Hobart, Wednesday 24 November
Duration: 5 days and 4 nights

Indonesia

Porphyry and epithermal systems of the Sunda-Banda Arc, Indonesia 

This field trip will introduce participants to the geology and mineralisation that characterise the Sunda-Banda arc. It will include site visits to porphyry Cu-Au and high-sulphidation epithermal gold deposits, modern hydrothermal systems on an active volcano (Mt Ijen), and exploration projects on Lombok and Sumbawa.

Timing: Pre-conference
Start: Lombok
Finish: Tujuh Bukit
Duration: 8 days and 7 nights

Mt. Ijen Crater, East Java, Indonesia


New Caledonia

Geology and Ni and Cr deposits of New Caledonia 

This trip is a rare opportunity to visit New Caledonia in northern Zealandia, a tropical paradise, and explore key aspects of its geology, its mining history and its mines. The tour will visit all tectonostratigraphic units, embracing the oldest and youngest rocks and sediments (beaches), as well as visit a number of active nickel and chromite mines. The tropical island scenery and French colonial features make this tour highly suitable for accompanying persons.

Timing: Pre-conference
Start: Nouméa, Thursday 4 November
Finish: Nouméa,Saturday 13 November
Duration: 10 days and 9 nights
