This does not make practical sense, at least in my view. The predominant problem in interplanetary travel is the presence of gravity wells. As Kim Stanley Robinson put it, "The hardest part is leaving Earth behind." Mars is smaller, but the resource base for getting minerals off it is nonexistent. Asteroid mining is a far easier method of obtaining just about anything you could want than strip mining Mars, with the bonus that you get them already in space.
In any case, the capacity to mine Mars is at barest minimum 50 years away, probably more like a century or two, if we're talking economic viability. It's too far away, the infrastructure (including an atmosphere!) is too undeveloped, and the alternatives are too easy.
As for "if it turns out to be highly habitable," I'm not sure what you mean. Mars has no atmosphere, no biosphere, no soil, and almost no nitrogen. Even under ideal conditions, where there are no real impediments to terraforming, a Mars capable of relieving population pressures on Earth is centuries or even millennia away.
