As for the pictures, here are some comments from the other board, edited to reflect a different order of pictures:
In your 4th picture, there are lots of new piles in the yard- and the main pile is freaking humongous. But maybe more significant are the new piles out back beyond the fence. Looks like even more than in the main pile in the fenced area. But they wouldn't put the valuable stuff outside the fence- so this must be the dump for what are now real "tailings"- ore after it has been processed by our mill. Anyone who thinks that the mill has not been processing a significant amount of ore should have a look. The piles must be 20 feet high by 100 feet wide. Maybe 50 feet deep? That would be 5000 tons- close to 100 tons per day for a couple months. My numbers may be off- but that's still some big piles.
The other new item is in your first picture of the "back" side of the mill. A conveyor has now been added to the outlet of the horizontal conveyor that comes out of the side of the building. It is now certain that the horizontal conveyor is an output conveyor- since it dumps onto the new conveyor, which then heads up. Wonder what it will dump into? You can see some small piles beneath the new conveyor, so they have at least been testing it.
To repeat- lots going on at the mill- continued construction and additions, and indications that a lot of ore has been processed.
