Were our civilsation to fall or become extinct no future civilisation would ever reach our level. Why?. Because we have mined all the minerals freely available on the Earths surface. Future civilisation would need to develop deep mining technology to reach our level and they can not do that without the very resources they can not reach.

Well, if you think about it... that's not true. Really, we were just nice enough to bring all of it up to the surface. Sure, we've combined it into various different forms, but it should be relatively easy to take, say, a partially oxidized aircraft, and extract the aluminum and other metals in it. The bigger problem would be the amount of time needed for another intelligent species to develop.
