Regional Scale Mapping with Aster

Accurate and dependable mapping of alteration minerals is essential for exploration projects. Using satellite images, PhotoSat’s proprietary processing methods enable exploration targeting through the clear and reliable identification of alteration minerals relevant to several different deposit types including epithermal gold and silver, and porphyry copper.

PhotoSat offers a geological alteration mapping package produced using ASTER satellite photos. The ASTER satellite provides the best data for regional prospecting, covering areas up to thousands of square kilometers. 

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.

We regularly publish case studies and reports; sharing proven success stories and best practices that demonstrate the effectiveness of our alteration mapping packages.
