The Grace Mine closed operations in 1977 due in part to depressed iron/steel prices and the high cost of underground ore extraction. The dumps were later used in road/ramp highway construction. Final reclamation of the property by Morgantowwn Properties began sometime after 2004, for an extensive housing development project.

The project "Bryn Eyre" is a housing project in which an entire town, 12,393 residential homes, commercial, school and public areas will be built on site. Projected to be constructed over a 20-25 year period, it is the largest such project in Pennsylvania since the 1950's. (Ref. R. Robinson, Lanc. New Era, 2007)

Ground breaking began April 1, 2007 (observations: Ms Sophia Shultz).
