Abstract
Large areas of prospective North-West and North Queensland have been surveyed by airborne hyperspectral sensor, HyMap®, and airborne geophysics as part of the " Smart Exploration" and Smart Mining" initiatives of the Department of Mines and Energy Queensland. In particular, 25000 km2 of hyperspectral mineral and compositional map products, at 4.5 m spatial resolution, have been generated and made available via the internet (http://www.em.csiro.au/NGMM/; http://www.dme.qld.gov.au/mines/hyperspectral.cfm) (Figure 1). In addition, more than 130 ASTER scenes were processed and merged to produce broad scale mapping of mineral groups (Figure 1) (Thomas et al, 2008). Province-scale, accurate maps of mineral abundances and mineral chemistries were generated for North Queensland as a result of a 2 year project starting in July 2006 involving CSIRO Exploration and Mining (www.csiro.au/science/psl6a.htrnl), the Geological Survey of Queensland (GSQ) (www.dme.qld.gov.au/mines/hyperspectral.cfm), Geoscience Australia (www.ga.gov.au). James Cook University, and Curtin University. This project also involved CSIRO’s Minerals Down Under National Research Flagship (MDU - www.csiro.au/science/MineralsDownUnder.html), the Cooperative Research Centres for Predictive Mineral Discovery (pmd*CRC) and Landscape Environment and Mineral Exploration (LEME), and HyVista Corporation (www.hvvista.corn).
