8. East Riverina Mapping Project – Overview
• 5 year project (2014-18)
• Multi-discipline approach
• Enhance geological data in an
underexplored terrane
– Higher resolution mapping
– Crustal framework
– Constrain geology & timing
• Develop exploration models &
mineral prospectivity
– e.g. porphyry Cu-Au,
orogenic Au, magmatic Sn
• Quarterly project updates
9. East Riverina Mapping Project – Progress
• Field mapping completed for
Ardlethan & Barmedman
– Currently mapping around
Wagga, Temora and Henty
• 35 new SHRIMP ages (with GA)
– Magmatic history
– Sediment provenance
• Identification of age-diagnostic
fossils to aid stratigraphy,
structure
10. East Riverina Mapping Project – Progress
• 3D and potential field modelling
– Crustal framework
• Deformation and metamorphism
– Strain, kinematics, timing
– P, T & timing of heat / fluid
transfer to upper crust
• High quality geophysical data
– Magnetic, gravity, rads
– ASTER review (Hewson)
• Collaborative projects
– Uni of Newcastle

11. East Riverina
Minerals Systems
• Improved MetIndex data
– Endowment
• HyLogger™ scanning of core,
uploaded to AuScope
• Isotopic studies
– Timing (Ar-Ar, U-Pb)
– Nature of fluid (S, Pb)
• Tin prospectivity study (CET)
• Developing exploration
models & prospectivity maps

Also – University of Queensland, Queensland University of Technology
Partner Investigators – GSQ, GSNSW
1. Systematic age determination of
key lithostratigraphic units
2. Detrital zircon age spectra of
major sedimentary units for
provenance analysis
3. Kinematic analysis and Ar-Ar age
determination of major fault
structures and syn-kinematic
intrusions

14. Yathong Trough Seismic
• 2 lines (229km) deep seismic acquired in 2013
• E-W line extended approximately 50 km westward into the
Lachlan Orogen, to provide data for mineral systems studies in
the broader Cobar region.
• N-S line has been of
particular benefit to
the understanding of
the sub-basin
structure
• Data now available
for download from
Geoscience Australia.
