This Study Tour continues a series of courses presented and managed by Porter GeoConsultancy Pty Ltd for the Australian Mineral Foundation and immediately followed the New Generation Gold Mines Conference in Perth.

It visited a selection of the more significant new deposits discovered over the last five years, mines that have gone into production during the same period, as well as some longer established, and better understood orebodies in the same districts.

The seven mines and projects visited extended from south of Kalgoorlie, to Wiluna in the north, and cover the current hot exploration areas.

The seven mines and projects on the itineray included the following:

  • Ghost Crab/New Celebration - New discovery and mine, as part of a mature project.
  • Golden Cities - New discovery.
  • Sunrise Dam - New mine, mainly in oxidised ore.
  • Chatterbox Shear Zone - Whisper, Rumor, Inuendo - New discovery.
  • Granny Smith - Mature project (same district as Sunrise Dam, Chatterbox Group & Wallaby).
  • Wallaby - New discovery.
  • Jundee - New mine.
Most of the new discoveries were covered by papers presented at the conference, and as such allowed participants to see at first hand the ore, host rocks and ore controls described. The visit also gives an impression of what, if any, surface expression there was of ore, and what inspired the discovery.

The new mines took the participants to the next stage, and allowed for a three dimensional sub-surface impression of the ore, both in the oxide zone for the most recent open pits, and the primary zone for those that are more advanced.

Finally, established mines in the same district as the new discoveries allowed access to much better understood deposits, to compare and gain an impression of what the new discoveries can eventually grow into, and see how the actual orebody, as mined, relates to the initial drill interpretations.

The primary focus of the tour was on exploration and mine geology, although attention was also be devoted to the mining, metallurgical and economic aspects of the operating mines.

The tour commenced at the Burswood Resort in Perth with a brief Introductory Meeting on the evening of Tuesday 23 November, and ended at Perth Airport in the late afternoon of Saturday 27 November. The tour arrangements and fees included all surface and air travel, mine visits, organisation and logistics between the start and end in Perth.

Tour participants were from around the world. They will brought a breadth of international experience to the tour that broadened and enriched the discussion and greatly enhance the tour.

All of the arrangements were be made by PGC on behalf of the AMF to allow the maximum impact, in the minimum time, and at reduced costs.
