The mining majors, BHP, Rio Tinto, et al have petabytes of surface geochemistry, samples, near surface magnetic maps that penetrate into the crust, 3D seismic maps, drill cores, technical reports on every mine ever, surrounding geology, and good models on where economic feasible (at particular price points) amounts of desirable metals can be found.
For example, there are only so many places significant masses of porphyry copper deposit will be found (although these aren't the only types of copper deposit).
For people interested in subscribing, there are databases such as the S&P portal that scratch some of that industry knowledge.
although they seem to have backed off from a public page about the GIS portal to the mining databases they purchased.
So; pretty much most areas have been scratched - Antartica is still open, the Artic has possibilities .. but should we.
There are known untapped masses of copper, eg: in the US there's a mass that will take 64 years to mine .. that's on Apache land so, you know, it'll be US history all over again poking that one.
