This raises a number of points. I certainly have no axe to grind with Norpex, however:
#1 The place has virtualy been stripped of artefacts already, a saying about "stable doors" springs to mind.
# 2 What if any arrangements will be made for explorers such as myself who only take photographs, albeit poor ones.
#3 Bearing in mind the fate of the previous gate, is the new one to be the subject of some kind of lottery.
# 4 The ownership of the mine is not with Norpex, unless I am misinformed. Has authorisation been sought with the owners, the County Council or NPHT?
