Insights gained from HyLogger spectroscopy in minerals exploration targeting

*This is an abstract only. No full paper is available for this abstract.* Several advances in the HyLogging SystemTM has seen the progressive evolution of the technique, including the commercialisation by Corescan in May 2017. The broad range of the infrared spectrum covered (400-2500 nm and 6000-14500 nm) enables the technique to be applied in mapping and exploration targeting across a wide range of commodities. The generated data set can reveal important or often new vectors and create superior mineral system models, thereby adding value and understanding. This overview demonstrates the insights gained by this technique in several case studies.Short wave infrared and visible near infrared reflectance (SWIR and VNIR) has been applied with petrography and geochemistry at the Leven Star gold prospect in Central Victoria (Figure 1). This identified: mineral phases associated with sulfide mineralisation these mineral phases were structurally-hosted non-mineralised structures._x000D_
Thereby, a positive identification of minerals associated with mineralisation can vector future targeting (Travers and Wilson, 2015).The generation of near-comprehensive mineral maps and geological classifications can be used to identify the extent of target host rocks (Burley et al, 2017). This is demonstrated in the Fisher East nickel sulfide prospects within the Mount Fisher greenstone belt, Western Australia (Figure 2).The differentiation of ores, alteration and impurities provides value to projects relating to gold, iron ore, rare earth elements (REE), uranium and base metals provinces. This is achieved through the spectral mapping of iron oxides, silicates, sulfides, carbonates and manganese-bearing minerals. Phases can be used to differentiate ore and impurities (Haest et al, 2012) or map alteration haloes that can range from the regionally extensive to the modest and precise vein selvedges (Wang et al, 2017).CITATION:Travers, S J, 2017.
