I have crushed a piece of rock the other day just for the hell of it, not thinking there would be any gold in it. It turns out I was wrong. I bashed it a bit in the mortar and just quickly panned it under a running tap. I hope you can see the gold in the picture below as it was quite a bit from such a small specimen (about 30 specs).
Now if I only remember where I picked the rock from. LOL
