Geochemical exploration is an important part of copper-resource evaluation. A large number of geochemical exploration techniques, both proved and untried, are available to the geochemist to use in the search for new copper deposits. Analyses of whole-rock samples have been used in both regional and local geochemical exploration surveys in the search for copper.

Prospecting from Orbit. Mining for ore isnt what it used to be. A hundred years ago when a mining operation happened upon a copper vein or a gold deposit, the outfit would often just rip out the local flora, excavate the land, and dump the resulting waste and rubble in the nearest pristine stream or flowering meadow.
