Recently, Mike Piersa uploaded some images of Grace Mine, which can be seen here:

A little background: Grace Mine was a former Bethlehem Steel Mine, situated near Morgantown, Berks County, PA. At Grace mine, magnetite ore with an iron content of approximately 40 percent was processed through the surface plant. It is first beneficiated to a concentrate of about 65 per cent iron content then baked into rock-hard marble-sized pellets for shipment to the blast furnaces at Bethlehem, Pa.
Bethlehem Steel started construction in 1951, in which they undertook the first step of the mine with the sinking of "A" shaft, the first of two. " A" shaft, which is 2,208 feet deep, was used for hoisting ore and transporting materials. Ultimately, "A" shaft was sunk to depth of "B" shaft, which is 3,079 feet. "B" shaft was used for men and materials. When the mine closed in 1977, both shafts were sealed and the headframes were torn down. Today, the hoist and compressor building still remains, but unfortunately, vacant.
Grace Mine was the last iron ore mine to close in PA.
After the mine and surface plant closed, developers were toying around with different ideas for the site, but eventually it became an industrial park. Visitors today will notice that only the substantial buildings remained, seen in Mike's images, while the headframes, pelletizing plant, crushing and screening plant, mill tailings thickener tanks and raw materials conveyor system, were all torn down.
