I revisited the Copper Mill in order to try and do the tomb to the far north of the area. I climbed all the way to the top, where I found that that the area you fight the 'boss' in (those flamer chaps) is blocked by burning debris.
So I cannot progress past this to reach the other side.
Going back down, I need to back eject (jump back off a wall) in order to land on a balance beam, which I can't figure out either.
So am I really stuck, or is there a way through the Copper Mill, once completed, or a secret way back down to the camp in order to fast travel?

I didn't understand David Yell's own solution, but here is another, probably easier way:
Standing all the way at the end at the top, facing the burning debris that's blocking the way, turn right 90 degrees, and, above the stairs you came from, there is a ledge. Climb it, and from the platform you've reached there is a sort of chute down to a secluded area at a lower level.
