*NEW* Annual General Meeting 3 May - Advance Notice & GSA WA Division committee nomination form

The Western Australian Division of the Geological Society of Australia will hold its Annual General Meeting beginning at 6 p.m. on Wednesday 3 May, at the Irish Club of Western Australia in Subiaco.


The provisional Agenda is provided on p.9 of WAG522 (April – May 2017); the Annual Report on the Division’s activities in 2016 will be distributed in due course.


Most importantly, the biannual election of the Division Committee Executive (Chair, Vice Chair, Secretary, Treasurer, Business Manager, Newsletter editor, Web Master) is to be held at this AGM. Several of the current Executive will not be nominating for re-election to their current roles. It is critically important for the continuity of Divisional activities that there is a smooth transition to the new Committee, and all members are therefore invited (indeed urged) to nominate to the Executive. We also call for expressions of interest in becoming general members of the Committee, to represent the different professional spheres of the Society (academia, industry, student).

Talk title:    Lithium-caesium-tantalum pegmatites, targeting techniques and recent WA advances


Speaker:    Mr David Crook, Managing Director, Pioneer Resources Ltd, West Perth, WA 6005


Abstract:    Pioneer was one of the plethora of companies that elected to explore for LCT (lithium-caesium-tantalum) Pegmatites during 2016. It became quickly evident that systematic exploration for alkali metals has been negligible over the last 50 years, resulting in a vacuum of knowledge relating to LCT Pegmatites in general and exploration techniques thereof.

This talk will draw illustrations from the Company’s Canadian and Australian Projects to describe the geological setting and geochemical signatures for detection of fertile LCT pegmatites to provide a robust set of criteria which, we trust, will result in the discovery of further LCT Pegmatite-hosted alkali metal deposits.

With regard to the Western Australian Sinclair Zone pollucite discovery, the first of any note in Australia, and recognising that there are very few dots internationally to join, the incompatibility of caesium in the usual pegmatite alumina-silicate minerals means that pollucite forms in the most differentiated phase of the LCT pegmatite, following, we suspect, the point of caesium saturation of micas. 

Much of the background information drawn on for Pioneer’s understanding is from:

  • Bradley, D., and McAuley, A. (2013): A preliminary deposit model for lithium-cesium-tantalum (LCT) pegmatites.  U.S. Geological Survey Open File Report 2013-1008 7p.
  • Selway, J.B., Breaks, F.W and Tindle, A.G., (2005) A Review Of Rare-Element (Li-Cs-Ta) Pegmatite Exploration Techniques For The Superior Province, Canada And Large Worldwide Tantalum Deposits.  Exploration and Mining Geology, Vol 14, Nos 1-4 pp, 1-30.
  • London, David; Pegmatites, (2008): The Canadian Mineralogist Special Publication 10.
  • Internal documents recording the analysis of geochemical results by Dr NW Brand, Geochemical Services.



About the speaker:    David Crook attained his BSc from the University of Canterbury, NZ in 1978, and has worked as an exploration geologist and manager predominantly in Western Australia, since 1980, accumulating over 30 years of experience across gold, nickel sulphide, nickel laterite and other commodities.


Amongst other exploration plays, he was in the discovery team at the Radio Hill Nickel Sulphide Mine, the reserve-build and early production for the Gidgee Gold Mine and the acquisition and drillout for the North Kalgoorlie Nickel-Cobalt Project.  He has been Managing Director of Pioneer Resources Limited since its IPO in 2003.


Pioneer commenced exploring for LCT pegmatites in Western Australia and Ontario, Canada, in mid-2016 and recently announced that it has discovered a modest, but it seems globally significant, deposit of the caesium mineral pollucite.

Gibb Maitland Medal 2017

Call for Nominations - Now Closed


The Gibb Maitland Medal was established by the Western Australia Division of the Geological Society of Australia in order to recognize individuals who have made substantial contributions to geoscience in Western Australia.  It is named for Andrew Gibb Maitland, Government Geologist from 1896 to 1926, who established the Geological Survey of Western Australia.  The Medal is usually awarded annually and nominations are now sought for the 2017 Award.


In assessing nominations, the primary consideration will be the significance of individuals’ contributions to geoscience and the quality of their scientific work.  To reflect the importance of resources to Western Australia, particular consideration is given to contributions that relate in some way to discovery or documentation of mineral and petroleum resources in the state.  Geoscientists from industry and from academic, government or other institutions are all eligible for the award, but especially those who are actively engaged in their careers, whether in Western Australia or not.  Unsuccessful nominees do not have to be renominated because their names automatically remain on the list for annual consideration for five years, although sponsors may wish to update the nomination.


Recent recipients of the Medal include:


2005   Dr Jon Hronsky                                WMC Resources

2007   Dr Peter Eadington                          CSIRO

2009   Mr Philip Commander                     Department of Water

2010   Dr Tim Griffin                                    GSWA

2011   Dr Stephen Barnes                         CSIRO

2012   Dr Scott Halley                                 Mineral Mapping Pty.

2013   Professor Cam McCuaig                Centre for Exploration Targeting, UWA

2014   Dr Ravi Anand                                 CSIRO

2015   Dr Graham Begg                              Minerals Targeting International Pty Ltd

2016   Professor Kliti Grice                         Curtin University

No awards were made in 2006 or 2008


Nominations should be in writing, with sufficient details of the nominee to allow evaluation by the Awards Subcommittee.


2017 Gibb Maitland guidelines & nomination form download: MS Word doc


Nominations will be strictly confidential and should be sent to the Convenor no later than Monday 28th November 2016.
