Cracked open a rock only to find an amazing surprise inside

Found this today up in carefree Arizona. Looked interesting and was really dense and heavy for its size. It has a black crust on it and some weird black crystals in it aswell. The small pieces are just from a small piece of it. I still have almost the whole thing to break down. What do you guys think

Granite, magnetite, and hornblende. The black crust is desert varnish. My guess anyway..

. It looks like it was in a highbrow thermal vein
And that is a very good area for gold to form as it could be leached out of se rounding host rock . Hard to tell from pix . I do fire assay's when I find something that makes me ask questions of such . May be something or may not .

Pretty rock.

It's Chalcopyrite with a little Bornite. That mine is owned by a friend of mine. I've been familiar with that ore since 1980. It does contain some gold values but that small of a piece isn't going to net you much, if any, gold.

jair is right, it's a rich hydrothermal deposit. The cap is mostly missing off the gossan but the structure is still evident.
