I think the 'gold' would be the hash collisions that the mining process discovers - this is like gold in the sense that these hash collisions are mathematically scarce and of finite supply, and very difficult to discover/extract. They are unlike gold in that they are not very useful by themselves, whereas gold is used as a material in many things.
