ALTERATION PACKAGE DETAILS
PhotoSat uses Short Wave Infrared (SWIR) bands produced by two satellites to map both larger scale regions and smaller areas.
PhotoSat uses proprietary data processing technology developed with deep learning to improve the accuracy and reliability of alteration mineral mapping. PhotoSat has been able to continuously improve spectral matching and reduce incidences of false positives to accurately identify more subtle alteration zones and map more effectively in partially vegetated areas.
Deliverables are provided in a clear, easy to understand format that identify areas of possible to probable alteration, allowing resource exploration companies to communicate findings to stakeholders. With reliable data identifying areas of probable alteration, targets for sampling or drilling exploration can be defined with confidence.
PhotoSat offers a geological alteration mapping package produced using ASTER satellite photos. In larger areas with sparse vegetation, ASTER photos are used to map opal/chalcedony, total silica, kaolinite, jarosite, sericite, chlorite, calcite and many other minerals for epithermal gold and silver and porphyry copper exploration.

PhotoSat’s geological alteration mapping package produced using WorldView-3 high resolution satellite photos offer about 64 times the spatial resolution of ASTER alteration mapping. In areas of sparse vegetation, 16 band WorldView-3 photos are used to map opal/chalcedony, kaolinite, jarosite, sericite, chlorite, calcite and many other minerals for epithermal gold and silver and porphyry copper exploration.
