No,How can you mine a resource you can't see?? I suspect KCD will look at the resource screen to determine you have all the resources. I think the rules are quite clear. If you pick a corp that requires modern resources like aluminium. coal or Uranium you need to research the related tech and have all the resources worked or traded for on the map.
I think all you need to do is have all the resources worked or traded for. You don't have to actually learn the tech. Although you would probably want to.
For aluminum, AFAIK it always occurs on hills. So, if you control and mine every hill, then you will also control all the aluminum.
