Metals have nothin' to do w/ makin' the planet inhabitable on any level.
They'd need to build a huge chamber that can create an artifical atmosphere and survivable temperatures (keepin' in mind that humans would instantly freeze to death on Mars) and find a source of renewable food.
We cannae exactly jus' plant some orange trees and ship over some coo's to farm so food would still have to be supplied from Earth. Water and oxygen could be renewed but thas obviously not enough.
So a small number of people can stay for short periods of time living off of supplies fed from Earth while they advance said chamber.

And that's after they've actually built the chamber which will take....several...several years at absolute minimum.

And then thas only astronauts and engineers.

And then that's still only very temporary solutions.

To turn that into a permanant livin' situation that can sustain more than a score of astronauts would take longer than any of our families will be alive and cost more money than we have.
And that's assumin' that all goes to plan and we land in 2020...which isn't likely.
