16th SGA Biennial Meeting 2021 , Rotorua New Zealand

The 16th Biennial Meeting of the Society for Geology Applied to Mineral Deposits (SGA) will take place 15-18 November 2021 in Rotorua, New Zealand. 

The meeting will feature presentations on topics related to mineral deposit research, exploration, sustainable development and environmental and social aspects related to mineral deposits. The oral and poster presentation sessions, and pre- and post-conference short courses and field trips will provide a comprehensive programme.

The conference is organised by SGA with support from professionals in universities, research organisations, government, minerals industry, and service providers.

AIG is a supporter of the conference. AIG members may register for the SGA 2021 conference at the SGA member rate, a significant reduction in the conference registration fee.

AEGC2019 Data to Discovery

Perth will host the 2nd Australasian Exploration Geoscience Conference (AEGC) from Monday 2 to Thursday 5 September 2019 at Crown Perth.

The AEGC is the largest petroleum and mineral geoscience conference in Australasia, and incorporates the West Australian Basin Symposium (WABS) and the ASEG-PESA International Geophysical Conference and Exhibition.

The event will be jointly hosted by the Australian Institute of Geoscientists (AIG)Australian Society of Exploration Geophysicists (ASEG), and Petroleum Exploration Society of Australia (PESA).

The theme for the 2019 conference is “Data to Discovery”. The AEGC technical program committee has a focus on Geology, Geophysics, and Geochemistry and how these are applied in exploration for both Petroleum and Mineral systems in Australasia and the wider Asia-Pacific region. The conference has major sub-themes encompassing but not limited to:

  • New technologies
  • New information from old data
  • Local understanding from regional context
  • Workflows and methods that reduce cost/turnaround on projects
  • Cross disciplinary co-ordination
  • Case studies
  • Interacting and communicating science to the wider community.

A vital component of the 2019 conference will be the inclusion of dedicated streams for Australian basins, discovery techniques, mineral mapping, and remote sensing applications.

On behalf of the AEGC 2019 Organising Committee, we look forward to welcoming you to Perth.  Visit the conference web site for the latest information regarding the conference, accommodation, sponsorship and exhibition opportunities.

John Gorter and Tim Dean

PACRIM 2019: call for abstracts

PACRIM 2019 will be held in Auckland New Zealand, 3-5 April 2019 by AusIMM with the support of kindred societies and professional institutes.

The theme of the conference will be mineral systems of the Pacific rim.

This call for abstracts seeks the submission of practical and applied case studies for presentation at the Congress.

Please submit your abstract not exceeding 300 words via the speakers portal on the conference website, 

The organising committee encourages collaborative works and urges young professionals and students to make submissions and participate in the extensive and technical networking opportunities this Congress will offer.

The Congress will also offer a series of workshops and field trips in New Zealand and the western Pacific for professional development, and a full social program for additional networking opportunities.

We welcome abstracts with a geophysics and multidisciplinary focus that fall under any of the Congress themes.  Further details regarding the conference are provided by the flyer, available here.

Epithermal Au-Ag and Porphyry Cu-Au Exploration

Lectures and practical, 4-6 December 2018, by Greg Corbett and Stuart Hayward

December 4 & 5, York Club, 99 York St Sydney, lunch, morning and afternoon teas provided. Two days of PowerPoint lectures focus upon mineral exploration for epithermal and porphyry ore deposits derived from Dr Corbett’s 40 years field experience, including earlier short courses provided with the late Terry Leach from the early 1990’s. Exploration and mining examples from over 40 countries are used to delineate the characteristics of different epithermal and porphyry ore types, and controls to mineralisation, using tools such as alteration, structure and breccias. The exploration implications are considered throughout and a final section considers geological features recognised in exploration marginal to ore bodies. Participants will be provided with a current draft to the notes to be published by Springer in 2020.

December 6 – A practical exercise held W B Clarke Geoscience Centre, Londonderry, uses selected diamond drill core referred to in the lectures (above) and a set of teaching specimens to provide hands on training in ore and alteration mineralogy and the use of geological models. It is run by Corbett and Stuart Hayward, who has over 30 years experience in epithermal-porphyry ore deposit exploration and mining. A return bus from the city and lunch provided.

Prices include lunch, morning and afternoon teas and transport to and from Londonderry.

  • Students $150, but if you need assistance contact
  • Unemployed geologists $400
  • Employed geologists $1500

Minimum of 20 participants required and limited to a maximum of 40.

The Short course registration form is available via the Corbett Geology web site.

Miner critically aware of social licence responsibilities

The mining and exploration quest in and around New Zealand’s Waihi gold mine involves a high degree of social licence.

A consultant to OceanaGold Corporation (TSX & ASX: OGC) working on the Waihi operations, Rick Streiff, told attendees at the recent Gold17@Rotorua Conference that in Waihi the Martha open cut mine has operated in the town and that the latest underground operations go underneath some housing.

Streiff, who also undertook work for previous owner Newmont Mining, said it was clear from the outset that the mining companies needed to listen to the concerns of Waihi townsfolk and he believes this has been a successful operation.

There were some challenges for exploration including when operating teams needed to undertake CSAMT work to enhance underground targets that the wiring near houses did not create any problems. This took in looking out for dogs and cats.

There were noise issues that needed to be covered, including encasing drill rigs in containers to mute the noise and to ensure at night functions such as not using hammers on drill steels or rods.

Modern gold mining at Waihi began in late 1980s with a pit at Martha over the original underground mines and this was originally operated by a joint venture of US and Australian companies, then taken over by Normandy Mining before that big Australian company was taken over by Newmont, which in turn sold Waihi to OceanaGold in 2016.

Rick Streiff said that following on Martha’s develop the underground discoveries to follow included Moonlight-Favona, Trio and the 2009 discovery of Correnso, now the current mining focus.

Discovery of Correnso came about when exploration near the Reptile Vein came across an intersection that appeared to be “something else.” Ongoing exploration outlined Correnso as a significant target and there was excitement with an intercept of 11.5 metres grading 17 grams/tonne gold.

Broader regional exploration advanced originally by Newmont which undertook a remapping programme in 2008-09 identified a host of targets including the large WKP deposit which had seen holes like WKP24 outlining a wide zone grading 1.5 g/t and, later WKP35 which outlined an equally wide zone and a related narrow vein high-grade zone.

Streiff said modern mining at Waihi has seen about 2 million ounces of gold produced at Martha and roughly about one million ounces coming from underground mines. The ratio of silver varies, with Martha having had 10:1 silver to gold and Favona 1:1.
