A public inquiry into Dalradian's application for an underground gold mine at Curraghinalt near Greencastle in the Sperrin Mountains resumed at the Strule Arts Centre in Omagh. The Planning Appeals Commission investigation opened in January 2025 but suspended after concerns that the Irish government had not received notification and Donegal County Council lacked time to respond to a cross-border issue.

Commissioner Jacqueline McParland noted the inquiry faced similar issues to those a year prior. Conor Fegan, barrister for Fermanagh and Omagh District Council, stated new information from transboundary consultations prevented reasonable response time under law. Daniel Elvin, representing the Department for Infrastructure, said the Irish authority could access added details on the department's website and submit further input before permission decisions.

McParland asked Elvin if the department arranged access for Republic of Ireland authorities beyond website availability. Elvin confirmed information was posted online. Fegan argued public inquiries require timescales allowing parties to influence outcomes, not late additions. Emmett McAleer, former independent councillor, raised public participation concerns from late documentation.

Bill Donnelly, a campaigner with decades opposing nearby mining, claimed Dalradian documents still reference cyanide for processing concentrate, despite past withdrawal of such plans. He noted planning exists to process concentrate at Cavanacaw by Omagh Minerals, potentially allowing cyanide use. Counsel for the Northern Ireland Environment Agency said cyanide introduction anywhere in Northern Ireland needs a new application and public consultation.

Dalradian has worked on the site since 2009. The firm states the deposit holds gold, silver, copper and other minerals, with proposals for economic benefits including 1,000 jobs and contributions to local and wider economies. Opponents cite impacts on health and environment in the Area of Outstanding Natural Beauty. McParland scheduled decisions on transboundary issues for the next day.
