Geospatial Data for Exploration & Geology

Property Scale Alteration Mapping

Interpretation-ready data for property-scale exploration programs
For property-scale exploration, areas of interest can cover hundreds of square kilometers. When these properties are large or inaccessible, geologists may have limited surficial data to support exploration programming.

With PhotoSat’s Property Scale Alteration Mapping package, geologists get highly detailed mapping of alteration minerals to help select the best drill targets for advanced exploration, without the need for ground access.
Applications for key deposit types:
  • Epithermal
  • Porphyry
  • VMS
  • And many more
