Cave entrances are on the many natural cliff faces, but only on the east-facing and south-facing cliff faces. (read: not the 'thin' side of the cliff face) Currently it is unknown if they connect to one another, if enemies spawn in them, or if they are simply large randomly generated holes in the ground similar to mines. Presumably (read: i'm not sure) you can mine in them like a normal mine, so in a way, they're a easy source of metal for characters who don't have the skills to find and build a mine.
