Okay it's a photo from inside a side mine (the actual Berlin Mine has been closed to the public for years since a flash flood occurred) but it did pull out a small amount of metal. Unlike the actual main Berlin Mine, which went vertically down 365 feet, this went several hundred feet sideways into the hill toward the Berlin Mine.

Hard hat area for sure! Very cool - literally! Hopefully this doesn't display sideways. If it does I'll fix it later.
