Gold, which has a relatively high mass, would drop through the slats of the sluice boxes as the water flowed over them. Around the dredge were a half dozen radiator pipes to keep the water flowing through the machines.
The working end of the blast furnace, where molten metal would flow like lava out of the furnace… a process called ‘tapping’.
A mid-line polishing booth. It was fun to see the thousands of lasers and other sensors that guided the robotic arms and tools around the bodies as they passed. Note the red/green stop/go lights in the distance.
A machine to cast copper billets.
Two bin signs criss-cross in the North Annex.
Taken from the arm of the pocket loader–note the tree growing out of the conveyor belt. Often where you see old piles of taconite, trees are springing up. The byproducts of the pelletization process break down and make a really fertile mix, especially with all the iron content!

The man behind the curtain watches, but doesn’t say anything. Probably the smartest one in the room.
Empty spools, thousands of them, were around the mill.
