They are as rare as treasure chests, if not slightly less so. However, the majority of them are underground, below sea level (where the rocky background starts). So, if you're exploring above and building mostly, you will never find them, ever. As to the other person that replied: Yes, it's random... like everything else in this game, if you haven't noticed. I maxed out my health after 12-24 hours of gameplay, so it's fairly easy.
