A friend brought this to us from Utah. He says it's from a copper mine, but doesn't know anything else about it. Any info would be appreciated (I told him I would ask here). Whole Cut Wet

Don't see anything that looks like a copper mineral in that. The brown staining does look like limonite (iron hydroxide), which is common with a lot of the copper mines around here. But copper minerals are generally blues or greens.

Thanks. Your answer is close to what I said. Actually, your answer is a lot better than mine. I said something more along the lines of, "I dunno. Looks like iron."
