Not sure but mineables? Im probably oversimplifying because all my knowledge of getting stuff out of the ground comes from games but stuff like metals.
You mean like ores like copper, iron, rare earths that kinda thing. There are seems of minerals that are actually meteorites that have collected in certain spots on a glacier. Haven't heard anything about other large deposits but usually you would need to do all kinds of geological surveys to find that stuff and since most places are covered in 1mile+ of ice it's near impossible.
Oil rigs and mines aren't exactly living off the land. Dropping enough preserved food off to supply a facility wouldn't be too difficult. The main reason nobody's doing it is the international treaties involved
