In a statement to Northern Sound this lunchtime from Gyproc they have confirmed that the hole found on farming lands is unrelated to mining activity and there is no evidence of mining related subsidence,
"Following a site inspection on farming lands where a surface disturbance of the soil had been identified, there is no evidence of mining related subsidence, crown hole or sinkhole at the location. This inspection has confirmed that the soil disturbance is not related to any mine or mining activity. A full report is being sent to Monaghan County Council."
In a statement also this lunchtime from Monaghan County Council they confirmed that the road alongside the lands as inspections get underway.
Yesterday afternoon at 4:30pm, Monaghan County Council received notification from Gyproc/Saint-Gobain that they had been alerted to the development of a relatively small-sized surface opening on lands immediately adjacent to the LP4900 at Drumgossatt. The primary concern was that this opening might be indicative of a more significant sub-surface subsidence. As a precautionary measure, in the interest of public safety, Monaghan County Council has implemented a road closure. The LP4900 shall remain closed, pending the outcome of further site investigation. It is very much hoped that Saint-Gobain and Monaghan County Council shall be better placed to provide a more comprehensive update later this afternoon.”
