Where is the Metal?

Question for you scientific minded people, what effect does moving large amounts of metal ores from deep within the earth to concentrated areas on the surface (cities) have on the magnetism of the earth? I realize that the core carries most of the power for our system, but consider that the ores on the mantel have accumulated over millenia, while the bulk of the changes we have made have occured in only a few centuries and the quantities are staggering. Just something I feel no one has thought about like the effects of our insatiable hunger for seafood.
