All of the heavier metals on earth came from outside of the solar system (such as, for instance, Tungsten). How much of the ore deposits on earth do we attribute to extraterrestrial technology? I'd wager none.

All our own technological signatures will be reduced to odd mineral deposits if we wait long enough. On a planet with active geology like Earth, tens of millions of years should be quite enough to do it.
