Gyproc are maintaining the survey programs in place that monitor the lands and roads in area’s that relate to their mine workings. The monitoring program is important to ensure ongoing safety and we hope it provides reassurance to the community that our focus on the mine workings has not been diluted even during this unprecedented crisis of COVID-19.

Much of the routine monitoring takes place on a monthly schedule and the next round of surveying starts on April 13^th.

Over the next four weeks, in line with the program agreed with the authorities in late 2019, we will also prepare the area..
