LEME Minerals Exploration Seminar well received
The latest research developments within CRC LEME aimed at assisting the Australian mineral exploration industry find new mineral deposits was presented at the 2006 LEME Minerals Exploration Seminar held on Friday, 11 August.
More than 100 representatives from exploration companies, big and small, as well as State Government Agencies, attended the Seminar to hear LEME researchers discuss their latest work to find new geochemical and geophysical ways to locate mineralisation in areas of regolith cover.
Topics on the day included the inside story on the making of the Northern Territory Map and Atlas of Regolith Materials, a discussion on regional geochemical trends in laterites found in the south-western part of the Yilgarn Craton, and the potential of the humble spinifex plant in becoming a new medium to detect geochemical anomalies above mineralisation.
The response to the presentations and feedback received by LEME staff were both very encouraging. The high degree of interest shown in LEME research was also reflected by the large number of Centre publication purchases made on the day.

Humble spinifex could be exploratory key
THE common spinifex plant of Central Australia is proving a good indicator of mineralisation, according to the Cooperative Research Centre for Landscape Environments and Mineral Exploration (LEME).
LEME's research on Tanami Gold's Coyote gold deposit in the Northern Territory's Tanami Desert, which was presented as part of the centre's annual Minerals Exploration Seminar, revealed that spinifex leaves had shown elemental anomalies over known mineralisation.
The use of spinifex leaves as a geochemical sampling medium is one of the many topics under discussion at the seminar, which is designed to showcase new techniques developed by the centre that may aid Australian mineral explorers.
LEME Education and Training program leader Dr Steve Hill, from the University of Adelaide , said Australia was a continent that has undergone extensive weathering, erosion and deposition in many parts.
"Most surface or near surface mineral deposits have been found, mineral explorers now need to find cost-effective ways to find deposits beneath the weathered and transported material known as regolith," Hill said.
As a result, the centre has looked at improving the understanding of the physical, hydrological and biological controls of geochemical dispersion in regolith from mineralised areas.
"Our biogeochemical study of spinifex plant leaves over the Coyote gold deposit is one of the many ways we are doing this," Hill said.
"So far, a study by our PhD student Nathan Reid has shown that spinifex has great potential as a biogeochemical sampling medium throughout Australia , as its roots penetrate deep into the ground and it's common throughout arid Australia ."
The seminar held in Perth on August 11, also featured presentations on how other geochemical anomalies are showing up in vegetation over gold and base metal deposits, as well as breakthroughs. MORE INFORMATION ON THE SEMINAR AND ABSTRACT VOLUME AVAILABLE TO DOWNLOAD [2.7MB]

LEME STUDENT WINS BEST POSTER AWARD AT AESC
Anna receives her award from Geological Society of Australia President, Andy Gleadow
LEME Adelaide University PhD student Anna Petts has taken out 'Best Student Poster' at the 2006 Australian Earth Science Convention (AESC) in Melbourne July 06
The informative poster entitled 'Nature's Drillers and Geochemical Samplers: Termites and their implications for regolith geochemistry in northern Australia' summarised Anna's PhD project work in determining the potential use of soil biota as a biogeochemical sampling medium and regolith mapping tool in the Tanami Desert, located near the Western Australian and Northern Territory borders.
Anna's ongoing research focuses on the use of termite mounds as regional geochemical indicators and to establish a regolith-framework for estimating the depth of transported cover.
Anna explains: "In the Tanami, termites have been observed tunnelling tens of metres below the surface in the search for groundwater. Some of this material, which can contain anomalous geochemical signatures, is taken back to the mound."
"In effect, this means that mound-building termites, through their digging, undertake similar activities to regional geochemical sampling."
Her field research includes sampling mound material for metal content, regolith-landform mapping, geobotanical analysis. A GIS will be used to incorporate the multivariate data generated by her project.
Anna has already determined a relationship between termitaria density, vegetation assemblages and regolith landforms.

New 'atlas' highlights WA Wheatbelt's mineral potential
Data from this laterite geochemical database of WA's wheatbelt suggests the region has potential to host gold and base metal mineralisation. It provides a regional geochemical framework at a spacing close enough to recognise regional geochemical trends, major rock types and disperson halos around significant mineralisation.
"It contains a whole swag of new data that can be used for mineral exploration or land use management" Dr Cornelius said.
This collaborative "Laterite Atlas" project (Program 2 Research) is led by Matthias Cornelius (CRC LEME) and Paul Morris (GSWA) and funded by Minerals and Energy Research Institute of WA (MERIWA), CSIRO Exploration and Mining and LEME.

Congratulations to Baohong Hou who has been awarded a 2005 Churchill Fellowship
- from the Winston Churchill Memorial Trust "rewarding Australians striving for excellence"
Baohong Hou who is a LEME in-kind geologist with PIRSA, now has several credits to his name. Baohong and his colleagues have been complimented by Iluka Minerals for their palaeographic reconstructions of the Eocene shorelines of the Eucla Basin, which played a significant part in the recent discovery of the Jacinth heavy mineral sand deposit in South Australia. Then he was instrumental in getting up an IGCP project called Continental Fluvial Palaeosystems - Evolution and Mineral Deposits . In May-July 2004, Baohong undertook a exchange lectureship with five Chinese universities to speak on regolith work in Australia, and learn of CHIM electro-geochemical techniques in China.
Baohong will use his fellowship to interact with colleagues in US, Canada and Russia on palaeodrainage and electro-geochemical techniques of exploration through cover. Baohong will probably travel in the second half of 2006.

RIVERINA GEOCHEMICAL SURVEY
Collaborative project between CRC LEME and Geoscience Australia. First report on low-density geochemical surveys in Australia. Refer to AusGeo News Issue 78. June 2005.
Such surveys have not taken place here before, for a variety of reasons, and this first pilot project, in the Riverina region, outlines and tests a methodology adapted to Australian conditions. Geochemical surveys have a multitude of potential applications for
- natural resource management,
- mineral exploration and
- geohealth/environmental health risk assessment.
Please do not hesitate to give Project Leader Patrice de Caritat your feedback on this pilot project, as others are under way, and we are keen to collaborate with other state, federal, academic and international research organisations.
