This place is called Wall Street Mill. It is an abandoned gold ore processing site in Joshua Tree NP, USA. It's little know fact that there was a bit of gold rush in the area that is now know as Joshua Tree in the late 1800's that ran strong for a few years into the early 1900's. This site was active off and on until the 1966.

Looks like the south side of Jumbo Rocks. The quartz monzonite had bearing veins of quartz but the pickings were scarce.
I know it's all in the time of day, but I'd love to explore the angles and curves of the place since the metal contrasts with the rock so well.

@John, this is just a bit north of Barker Dam about a mile hike from that parking lot. I didn't have much time to stay, we decided to walk out there on the spur of the moment and it was looking a lot like rain, so we didn't tarry... I plan on going back again with better light and more time.

Sheer pleasure seeing this shot. Great BW tones. Nice composition.

Looks like an intriguing place. Nicely composed shot, and the only thing I would add is that the horizon seems a little high on the right and maybe crop it in a bit on the left, thats being fussy though...Great work.

Abandoned mine, isn't it?
I think you a bit overcontrsat this photo. Lights are to light and shadows are to dark. But nice place for great photos and this once as sugject, composition and so on very great!
