In reply to Samuel Wainwright:
As Ian Mc notes the Save Gillies Hill Facebook page gives current information about the site.
The whole picture is too complex to describe here but it is currently not being operated though permission exists to do so. The quarry is in split ownership and both parties are active in shaping its future, albeit not co-operatively.
The local community has been campaigning for many years to oppose the re-opening. There are currently several obstacles to new activity but we are well aware of how patient and thorough developers are in pursuing their interest. If successful then the whole area could be worked and even the existing climbing could be affected.
A proposal by the community for restoration of the quarry when the workings finished (Possibly 2042) included providing several climbing faces but was rejected by the developer.
