The ice would have scoured most if not all of the soil away, so the revealed continent would resemble a huge rocky plain covered in gravel, for the most part. Without intervention, it would also remain like this for millennia as it would take that long for the rocks to weather, lichens and mosses to begin "dissolving" the rocks and soil to develop, allowing for the colonization of the continent by plants, and eventually animals outside of the coastal region. This process will work somewhat faster in the places where volcanoes currently exist, since the volcanic ash and pumice are soft and easily weathered, and also make for a rich base for soil to develop.
The weather will be fairly harsh even without the ice (six month "seasons" of summer sun and winter darkness), and Antarctica gets little precipitation, so will be quite dry and arid.
As for natural resources, there is no reason to expect that minerals, oil and coal might not exist, since Antarctica underwent the same processes as the rest of the Earth, and even spent time in higher latitudes aeons ago, so would have supported life at one point. Prospectors and miners would be living and working in a very tough environment, and the high costs of supporting a large work force with imported food and everything else would make much mining and oil drilling less competitive than stuff mined or pumped closer to the markets of the world. Depending on political and economic events, it might still be worthwhile to exploit Antarctic resources.
