Still trying to find my way around GregTech earlygame. Didn't expect to be able to just craft nuggets into ingots, somehow.
But I don't understand how mining works. I think it does the TFC route of very few very large ore veins that you have to find?
But how do you find the knowledge to find them? In TCF prospecting was a thing.
Also are hostile mobs not supposed to spawn? I have not seen any.
Large veins, easily found by walking around the surface and picking up or inspecting rocks with a magnifying glass. When they say they bear some more, dig down to find it. You can also right click with a hammer to prospect, but I've never found it useful. Hostile mobs don't spawn within some distance of world spawn.
