Study shows Black Hawk mine larger than first thought

BLACK HAWK — Results of a geophysical study of the Hideaway Hills subdivision show that it is very likely that the mine extends underground well beyond the known mapped areas on the northeast, east, and southeast side of the subdivision.

And, according to an attorney who is part of the team representing Hideaway Hills homeowners, the findings show that there is also the possibility that the mine extends below Interstate 90.

“This interstate find is in agreement with possibilities left open by the (South Dakota) DOT study conducted over the summer of 2020,” said Patrick Ealy, director of Research and Communications for Fitzgerald Law Firm of Rapid City.

Mohammad Sadeghi, a professor of geological engineering at Montana Tech who has conducted multiple studies on gypsum, said in his summary of the study that data gathered in the Hideaway Hills subdivision in mid-May will help show the long-term stability of the gypsum mine located under homes there.
