hi there,the shaft (s) that richard b refered to are vent shafts, there are 4 of them, 3 of them are now capped with these which i made early this year: theres one biggy still to do,so i'll probably be back there soon to make another
Would you be able to point them out on a map?
Is the reason for capping purely so someone doesn't fall down there, or some other bizarre reason such as making the mine more dangerous?
