  3. Exploration Challenges • Easy “surface” mineral deposits were discovered a long time ago • “Exploration under cover” • Last 40 years – new geophysical/geochemical exploration technologies successful in deposit discoveries though….. • Increased global demand for commodities not matched by recent discovery rate • Understanding 4D processes of geological systems may advance future exploration success • Mineral Systems > Predictive Models > Vectors • Drilling still the ultimate exploration test • High cost but little “predictive” geological value extracted • Fundamental pre-competitive geoscience data missing from current strategies, such as • mineralogy • Mineralogical models (vectors) + spatially comprehensive mineralogy = • exploration success? Spectral In-House 2010

  4. What is Mineral Mapping? Hyperspectral sensing, spectral geology, imaging spectroscopy, molecular sensing, optical sensing The identification of mineralogy and mineral chemistry using reflectance and/or emission spectroscopy EMR absorbed/emitted by molecular processes (electronic, vibrational) at specific frequencies (wavelengths) Compositionally-diagnostic a “complete” spectrum measured for every pixel/sample non contact, non invasive, multi-scale in application. Complementary information to that of conventional exploration data (e.g. geophysics, geochemistry and geological mapping) Spectral In-House 2010

  7. pyrophyllite What Can Mineral Sensing Technologies Provide? • Seeing beyond the visible • Mapping of mineralogy from every pixel on the ground • See between the trees Spectral In-House 2010

  8. What Can Mineral Sensing Technologies Provide? • Seeing beyond the visible • Mapping of mineralogy from every pixel on the ground • See between the trees: • Accurate, seamless maps of mineral abundances and mineral chemistries • Laboratory-grade spectroscopy remotely Spectral In-House 2010

  13. CSIRO’s vision in Australia • Every drill hole logged for mineralogy • RC, RAB, diamond • Mineral map of Australia • Host rock, superimposed alteration (metamorphic and metasomatic), regolith mineralogy, as well as soils, vegetation cover (baseline environmental maps) • Environmentally sustainable! • drill core +remote sensing  3-D mineral map (+ multi-temporal  4-D) • Provided through the government geological surveys as part of their pre-competitive geoscience information suite • Web based delivery, distributed data archives, interoperability • Empower the exploration industry with tools for accurate mineral mapping • No longer used as “colorful” pictures for subjective interpretation or boardroom walls but for quantitative mineralogical analysis and “frontline” exploration Empowering the geoscientist with mineralogy Spectral In-House 2010
