I was at the Orient Mine mid 70's and there was nothing except a few foundations for worker housing and a big hole in the mountain. You could plainly see the old grade coming up from the valley. Since I drove mostly on a old wagon road that approached from the other side it is possible the boxcar was hidden by a terrain wrinkle if it was still there. There was a private cabin above the mine but didn't look very old and behind a locked gate.
Most of the mine now belongs to the hot spring resort south of the Orient who intend to prevent any development around the mine and have put the Orient Mine area in a land trust.
