The blacksmith shop is pretty rugged looking. Through the door you can see the collapsed walkway that might have once connected to a building covering the Santiago Tunnel adit.
The control room floats above the top of the dock atop a spiral staircase.
Identical warehouses seem a little newer than the rest of the plant. I suspect these were added in the mid-1950s for the Korean War, during which about 200 buildings were added to the complex.

It seems that the sawdust would be shot into a dust collector above the powerplant and burned.

The school (hospital) campus was expansive.
Two counterweighted elevators moved men between the surface, mine, and underground mill.
The Blacksmith Shop (right) was connected to the Bunk House (left) via this narrow walkway. This is likely due to the fire risk in each building. The left building had a cooking stove and furnace for heat and the right building had a small industrial furnace to repair mining equipment. A little walkway would mean that a fire on one side would be easier to fight from the other.
