Might be able to add some small clarification to aspects raised on this thread.
Pollution - the impacts on the River Ystwyth are zinc and acidity, followed by lead, with cadmium trailing. The mine is one of three largest polluters in the county. Statutory bodies have been looking at alleviation schemes for over 25 years (originally Welsh Water, later the National Rivers Authority, now the Environment Agency). There was a major consultancy a couple of years ago that included through liaison with stakeholders (including heritage bodies such as Welsh Mines Society and Welsh Mines Preservation Trust, local residents), though no concrete recommendations beyond it becoming clear that more detailed studies were required by the EA to better quantify the major pollution inputs. [A promising sign IMHO - better slow and cautious than rush in the JCBs]. Throughout all this, there appears never to have been a suggesrtion that the landowners could be clobbered with all/part of the costs of remediation - until the late 1980s or early 1990s the mining rights were owned by Cwmystwyth Mines Ltd (or a company of similar name), after it was dissolved, the site reverted to the Crown Estate. Whilst CMLtd had minimal assets and its handful of shareholders (two or three individuals only, I believe) probably had no more assets than their homes and cars, the CA was making a profit of around £90m p.a. a couple of years ago. Whether the lack of any apparent suggestion that the owners should pay for the pollution might reflect pragmatism that the shareholders of CMLtd possessed insufficent assets to be worth pursuing, and might possibly reflect perceptions of Crown immunity, I always gained the impression that the pollution was deemed to be deeply historic and that current owners would not be pursued. Cerainly the (admittedly modest) alleviation works undertaken at other mines in the county over the last 30 years have all been at public expense, I believe. So Roy iss probably correct in his assumption that neither he, nor his intended trust will be pursued over pollution (unless, presumably, he or the trust carried out works that changed the existing pollution situation) or the costs of alleviation. After all, a full blown alleviation project would cost a couple of orders of magnitude of the value of Roy's probable assets, or the likely assets of a group of trustees.
Access agreement or outright sale - the WMPT reported that in an exploratory meeting with CA a couple of years ago, that they were offered the site for a nominal sum. The WMPT considered the offer but, I am told, concluded that their constitution did not empower the existing trust to own a mine, and felt that they were already fully committed to preservation projects at a wide range of sites, and were not well placed to take on a major site such as this. Roy then reported at a meeting of the Ceredigion Mines Forum (stakeholder consultation group founded by the county council's 'Spirit of the Miners' project about four years ago, and now continued by the council's successor project 'Plwm') that, as a result of WMPT not feeling able to proceed, he was opening discussions with CA with a proposal that he would acquire the site and promptly transfer it to a trust, to be newly created, to safeguard the site, administer access, etc. Updates thereafter are on this thread, directly from Roy.
Will CA sell the site / why is everything so slow - crystal ball land; I know nothing more than the average contributor to this thread, I'm afraid, so what follows is no more than speculation (aplogies in advance). The matter is entirely in the hands of their agents. Whether they have an endless stream of more pressing matters, or whether they have doubts of some sort over Roy's offer, who knows. However, if they have not dismissed the offer, and of they are still talking, no matter how slowly, it must be a positive sign. Roy has a business background (read his website) so he is coming into this with his eyes open and can speak business language to the CA's agents. With the CA having made it clear that they will consider a sale of the site, but will not discuss an access agreement, Roy's offer is the best hope of the mining community for access, and indeed for conservation of the surface remains, as no other body, nor the current owners, are showing any meaningful interest in conservation of the deteriotating structures. The only potential obstacle I can detect is the possiblity that the CA's agents might prefer to sell the site direct to a trust rather than to an individual, whereas Roy stated (a year or more ago, admittedly - things may have changed since) to the Ceredigion Mines Forum that he is not prepared to go to the expense of registering a trsut until a sale is definite. It also occurs to me that there might possibly be some potential difficulty in finding trustees unless some of the potential liabilities of the site are mitigated. As a trustee of a charitable body (nothing to do with mining), I very carefully considered what I was potentially letting myself in for, as - in some circumstances - trsutees can find themselves laible for all their assets thanks to the litigatious nature of modern society and some perturbing case precedents. In the case of this site, an exchange of letters with the EA could provide suitable reassurance concerning the possibility of the proposed trust being pursused over pollution or its alleviation. However, with the greater part of the site being open-access under CRoW, and the afore-mentioned litigatious nature of modern society and some perturbing case precedents, there are some worrying potential liabilities for claims due to injuries by people wandering the site surface. However, the site comes with a grazing tenancy that brings in a modest but useful revenue each year so fensing and signage could feasibly be funded from that source and a suitably constituted trust would probably be able to tap into various grants to enhance access to the historic environment (on surface at any rate) that could probbaly be legitimately be partly applied to the mitigation of the risks inherant in the surface of the site. So, I can't see any over-riding obstacles and am cautiously optomistic that Roy's long and patient discussions may prove fruitful. Hats off to Mr.Fellowes for his stalwart efforts.
Couple points of interest - the greater part of the site is a scheduled ancient monument, the only notable exceptions being the dumps south of the road (which have been much reworked by the river; though the crusher house south of the road IS part of the scheduled monument) and western extremities of the site, which is mostly natural hillside. I believe that parts of the site may be a SSSI due to lichens and heavy metal -tolerant flora. I believe that portions of the site are a RIGS (Regionally Important Geological Site).
Hope these notes help understanding of the background and aspects of the 'wading through treacle' situation that Roy finds himself in his discusions with the CA's agent. There's a final caveat of course - this is the understanding of an individual not directly involved in the process, gleaned from various public statements and is probably incomplete, and possibly wrong in places. I have tried to flag up what is outright speculation on my part. Apologies, Roy if I've got anything wrong - I thought that an attempt at a fuller background might be of interest and would help engender patience in bystanders as your discussions drag on.
Thanks for your patience everyone.
