    Prospecting from Orbit. Mining for ore isn t 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.
