Sure, we'll never run out of fossil fuels, because as they get more scarce, the price will go up and some reserves that used to be unprofitable will now be. But then, we definitely don't want to burn all fossil fuels there are, because that would be catastrophic for the climate. Nevertheless, as long as it is profitable to do so we will. So we'll never run out of oil, and that is, in truth, unfortunate. In the same manner, we'll never run out of minerals, which is also pretty unfortunate because mining is somewhat environmentally damaging.
