Here's the problem: until the 1960's/'70s Antarctica's going to be dangerously far from the nearest shipping lanes, so that any industry is going to largely be local. Mining is hard because resource extraction blows nuts in permafrost, but it's only made worse in a place like Antarctica if you can't build a town around the region you want to extract in (I imagine towns would need to be near the coast but the mines are going to be a bit more in the interior). No one's also going to want to pay a premium for Antarctic mining when they could establish arctic mining in Svalbard for free (only Norway and Russia have done this fyi) or to simply import from a country that does it much cheaper.
Fishing is.. possible, but again it's going to be domestic. If you can somehow get a colony up before whaling becomes obsolete (for blubber and the like) there could be a small industry for that, but after that you essentially have the usual food-staples that stay in the Arctic zones because they're cheaper.

Industry, Mining, Fishing, and Hunting are the resources for a base.
