Drawing together some threads
• Look what we can do in areas of dense data coverage – great
but that’s not where the problem is!
• All that work (regardless of the current trends in economics,
commodities, exploration methods and scientific thinking) is
fundamentally pattern recognition
• All that work requires data/sample (there is no data undercover,
we need to get it). We need to drill to get a sample
• All that work requires a certain density of data in order to
recognise the pattern. How often do we need to drill?
• Different density of data relevant to different questions
Province selection (permissive terrane): Fundamental geodynamic
questions
Camp selection (mineral system): Reservoir delineation and fluid pathways
Targeting (deposits): Prioritisation, ‘vectoring’ within systems

What draws the research community
together?
• Geochronology and isotope chemistry – sample
• Mineral System footprints – sample
• Structural Geology – sample
• Lithospheric characterisation – sample
• Calibrating geophysics – sample
• Calibrating 3D models – sample
• NO RISK MITIGATION AND NO PROGRESS UNTIL WE SAMPLE
• NO SAMPLING UNTIL WE DRILL

The enduring value of the sample
• Provides research platform for all researchers (the sample is an essential part of the research infrastructure)
• Legacy – sample survives as trends come and go, available to future researchers and explorers
• Provides data levelling tool (important for incorporation of inherited data sets)
• Not just mineral exploration – informs diverse land use options (energy, water, agriculture)

What density of sampling is required and who
does the work?
• Province scale – to open up the search space, provide confidence for explorers to enter, precompetetive Targeted (stratigraphic) drilling of density required to identify
critical geology (~50km centres?)
Government (‘cause nobody else will)
• Camp scale – to map the mineral system from early in the exploration cycle Targeted drilling of density required to map the fluid pathways (~2
– 10km centres?)
Companies and Government/Industry alliances
• Target scale – to prioritise and move toward ore Targeted drilling to find ore grade horizons
Companies

The Challenge for UNCOVER
• Do we have the courage to ask for what is
needed?
• A serious, long term deep sampling (drilling
program) Thousands of holes!
• Linked to the Australian geoscience research
powerhouse
• In the context of continent wide (calibrated)
geophysics
