Spectra Analysis

GeoSpectra offers cutting-edge spectral remote sensing for regional- and camp-scale mineral/structural mapping and field target generation for precious, base, and critical metals using medium- to high-resolution multi-hyperspectral satellite imagery.

Regional Target Generation: We use Aster multispectral and EnMAP/PRISMA hyperspectral imagery to map alteration signatures, including argillic (kaolinite, smectite, illite), advanced argillic (pyrophyllite, alunite), phyllic (muscovite, phengite), propylitic (chlorite, epidote), carbonates, silica and iron oxides, as well as lineament analysis at a 15–30 m resolution.

Camp-scale Target Generation: We utilise commercial high-resolution multispectral WorldView-3 satellite imagery, additional exploration datasets, and mineral systems to identify favourable mineral targets and structural controls for further exploration. Both SWIR and VNIR data are used in the SuperCube format, ensuring all spectral bands are co-registered, orthorectified, atmospherically corrected, and resampled to a 1.24m resolution. This approach enables precise high-resolution mapping of alteration minerals (e.g., Li-bearing lepidolite in pegmatite dykes), iron oxides, and structural features, supporting robust target generation for follow-up exploration.
