A public inquiry into Dalradian Gold Ltd's proposed gold mine near Greencastle resumed in Omagh this week, with testimony focusing on the site's proximity to the Beaghmore Stone Circles.

The Planning Appeals Commission is examining the 2017 planning application for the mine and processing plant, which was referred by the Department for Infrastructure.

Representatives for Dalradian Gold stated the mine site lies outside the Beaghmore Area of Special Scientific Interest and argued there would be very low visibility from the stone circles.

The Historical Environment Division of the Department for Communities disputed those claims and requested further surveys to assess potential landscape impacts on the monument.

Objectors highlighted the Owenreagh Valley's historical significance, citing the Battle of Formil recorded in 965 and its role as a route used by the Cineal Eoghain.

Local historian Sean Clarke noted that people have lived in the Greencastle area for approximately 7,000 years, with additional archaeological sites discovered in nearby Broughderg in recent decades.

Third-party objector Pat Haughey said the area contains numerous ancient monuments and warned that 24-hour operations at the mine would introduce light and noise into the historic setting.
