A public inquiry into Dalradian's application for an underground gold mine near Greencastle in County Tyrone resumed on Monday at the Strule Arts Centre in Omagh. The Planning Appeals Commission, led by Commissioner Jackie McParland, is examining the proposal.

Dalradian plans to extract 100 tonnes of gold, almost 50 tonnes of silver, and 15,000 tonnes of copper from the Curraghinalt site in the Sperrin Mountains. The company submitted its application in 2017 and amended it in 2019 to exclude cyanide use. A spokesperson for Dalradian stated the project would create up to 1,000 jobs and contribute £9 billion to the Northern Ireland economy.

Save Our Sperrins members Fidelma O'Kane and Marella Fyffe attended the inquiry. O'Kane, the group's treasurer, expressed concerns over impacts to water, air, land, and public health. Fyffe, the chairperson, described the campaign as a stand for community and culture.

The inquiry, requested by former Infrastructure Minister Nichola Mallon in 2021, was suspended twice, including after two-and-a-half days in January 2025. The suspension followed findings that the Department for Infrastructure failed to notify the Irish government and Donegal County Council properly.

On Monday, similar procedural issues arose. Conor Fegan, barrister for Fermanagh and Omagh District Council, argued that new information submitted in transboundary consultations did not allow reasonable response time. Daniel Elvin, representing the Department for Infrastructure, said the information was available on the department's website.

Commissioner McParland noted the situation resembled the January issues and reminded attendees against heckling. She stated the department handles transboundary submissions, with a decision due the next day. No Irish state body representatives attended, despite invitations to all state bodies.

The inquiry will address issues including cultural heritage, waste management, landscape, climate, transport, and socio-economic factors. Hearings are scheduled for at least 21 days over eight to 10 weeks.
