Anyone recognize this one from the U.P.? I have several pieces...

Looks to be a conglomerate with Calcite, not seeing obvious Copper though.

It doesn't look like any conglomerate I've seen. It does appear iron-bearing. Need some streak and hardness test.

Not like any copper that I have seen.
Looks like rusty iron bearing rock with calcite.
If it were copper, even a radio shack detector would scream from it.
