Just come across this thread. I went on one of their tours in August 2008 with Cumbria Industrial History Society. It was absolutely first class. We were split in to two groups. One went undergound in the morning while the other toured the mill.
You are driven in landrovers down the incline into the mine and taken directly to the face of one of the "districts" which is well below 1000 feet undergound. You will see loading activities, how the gypsum is won, drilling the shot holes and how the charge is fired. You then follow the gypsum on its 2 mile conveyor journey to the mill.
The company provided a light lunch and then the parties swapped and we were taken on a tour of the mill to see the plaster and plasterboard being made. Very impressive.
Everyone from the receptionist to the shot firer to the mill hands was really helpful and intensely proud of their product.
Nice to see in this day and age.
The company also do a geological day when the company's geologist is present and this also includes a trip down the mine
Back then I was going to ask if anyone on Aditnow would be interested in an organised visit but as I had only been a member for a month or so, I decided against it.
Will will ask the question now. Is anyone interested?
I do know that the company monitor sites like aditnow so any comments or suggestions of ways to get in would be very unhelpful. It is after all a working mine that has to comply with all H & S and Mines and Quarries regs.
Don't wait for a light to appear at the end of the tunnel, stride down there and light the damn thing yourself
