Key Data Sources for Modern Exploration

Today 's exploration datasets come from a wige variety of sources, each offering a different window into the subsurface.

Satellite Imagery andRemote Sensing

Satellites such as NASA 's Landsat, ESA' s Sentinel, and commercial platforms like Maxar provide multispectral and hyperspectral imagery. These images can decret surface mineral signatures, alteration zone, and structural lineaments that of ten surround or e bodies. Advanced processing of Satellite data can also identify subtlie variations in vestition stress, soil chemistry, and thermal pergens thatt hint deeper deposits.

Geochemical andGeophysics Data

Geochemical gestics measures thee concentration of elements in soil, stream sediment, rock chips, and water.
