It's ''endless-resources-depletion'' by Morhe, which was basically the only mod what did what expected and worked on every scenario correctly. Updated for 1.0, if he ever updates his version I'll delete this one. All ore resources are infinite but their yield will deplete to very low amounts.
RSO & Bob's Mod compatible.
