I threw a piece if U Ore that I bought a couple years ago in the scope to see what it would show, here it is, no pic of the sample, it was pretty boring looking:

I was surprised by the gold. I guess I should have not been, U was first found in Gold mines so says the internets. But I am scanning a very tiny piece of the ore so who knows if it is homogenous throughout the sample.
