During World War II, the mine and works were leased to the Redlands Coal Company, a commercial operator.

The Pine Township Company evidently leased the Mentcle Mines at a later date, but operations were shut down permanently c. 1960.

The front-gable houses are built on concrete block foundations and are topped with shingle roofs with brick chimneys near the center of the ridge.

The Mentcle Mine complex was located to the north and east of the town, across Yellow Creek, along the former Cambria and Indiana Railroad.

This brick and iron building has a shed roof and c. 1993 contained an intact 16 feet (4.9 m) diameter metal fan and housing.
