After much discussion and research, the 6ias and Target 2020/2022 Committees regret to advise you that they have decided to postpone the 6th International Archean Symposium (6ias) and Target2020 (to be rebranded Target 2022) conferences until 2022. We note that the 2021 calendar year is now filled with conferences already booked and those transferred from 2020, and we continue to face ongoing uncertainty regarding the opening of international borders. As such, we have decided that hosting the Target 2022 conference and the symposium in 2022 will maximise the opportunity for participation for our international Archean community. We anticipate that the conference will be held sometime in the mid-year.

Important dates and deadlines for registration for the 6ias and Target 2022 will be announced next year via this webpage. Please subscribe to the 6ias newsletter for further announcements.

During the remainder of 2020 and into 2021, the 6ias, Target 2022 and Geoconferences committees will endeavour to foster the global Archeal-Paleoproterzoic geoscience community through the development of a regular Webinar series.

For information regarding existing registrations for 6ias and Target 2020, please contact Jocylen Thomson, Geoconferences Secretariat, at

Please keep safe and we look forward to welcoming you to Perth in 2022.

Targeting for a New Era of Discovery

The Target 2020 Organising Committee are pleased to announce the upcoming Target 2020 conference, Targeting for a New Era of Discovery. The Target 2020 conference will be held at the University Club at The University of Western Australia in July 2022 in Perth, Western Australia following the 6IAS.

After the great success of Target 2017, Geoconferences is organising Target 2020 to showcase innovations developed to aid the discovery of new tier-one deposits and broaden the exploration search space under cover. Target 2020 will focus on all aspects of mineral exploration and provide a unique opportunity to workshop solutions to the mineral industry challenges that lie ahead.

We expect more than 250 attendees from both the Australian and international mineral exploration community, including executives, exploration professionals, researchers and university students. The technical program will consist of a plenary format and multiple poster sessions, impacting multi-commodity exploration from the regional greenfield scale through to camp scale.

The program will highlight:

(i)           Key research outcomes that impact our understanding of Mineral Systems and the derived exploration strategies

  1. Putting time and dynamics into improved Mineral Systems prediction (Cam McCuaig)
  2. Deposit periodicity and clustering (Nick Hayward)
  3. Isotopes, trace elements, and productive Mineral Systems (Crystal Laflamme)
  4. Large-scale crustal architecture as a first-order control on Mineral Systems (David Mole)
  5. The whole-lithosphere Mineral System context (Karol Czarnota)
  6. Upper crustal spatial organisation within ore systems: A new prediction power (Tim Craske, Bruce Hobbs, Alison Ord)

(ii)          Data integration, interpretation and key exploration targeting inputs

  1. Hydrothermal alteration in space & time (Heidi Pass)
  2. Mapping Trans-Lithospheric Faults using integrated geophysics (Ruth Murdie)
  3. Multi-scale application of magnetotellurics (Kate Robertson)
  4. The new generation of pre-competitive data (Paul Duuring)

(iii)         Improved targeting strategies and methodologies

  1. Putting geochemistry to work (Paul Agnew)
  2. The way forward for Prospectivity Mapping (Jon Hronsky and Oliver Kreuzer)
  3. 3D prospectivity and machine learning (Becky Montsion)
  4. Drilling with a dynamic targeting feedback loop (Michelle Carey)
  5. The Gruyere Discovery Case Study – out of the box (Clayton Davies)

We look forward to welcoming you to Target 2020 and together shaping tomorrow’s exploration strategies for the future sustainability of our industry.

Abstract Submission

The Target 2020 Organising Committee welcomes authors to submit abstracts for Poster Presentations only. Poster sessions will be held throughout the day. Authors of the six most outstanding abstracts will be invited to participate in 2-minute rapid-fire summary talks. 


Registration will be open closer to the event.
