Being a part of a European mining heritage organisation means that I have participated in trips to mines in the Czech Republic, UK, Germany, Norway, Italy, Poland, Spain and Ireland. I think it would be great to organise overseas mine trips, but it is my experience that in order to run a truly successful trip, you really need to have people in the know (at geological surveys, mining heritage attractions, universities etc.) to help to plan such events and obtain permission if necessary.
Issues such as access to abandoned underground workings and permission to explore mine buildings on private or state owned land can sometimes be problematic. For example, here in Ireland permission must be sought from the DCENR (Dept. Communications, Energy and Natural Resources) before venturing underground. In Spain there is not a culture of mine exploring such as we enjoy in Britain; it was forbidden to enter abandoned mine workings during the Franco era, and I get the impression from the sites I have visited (Tharsis, Rio Tinto, Linares, Alcarajecos, Cartagena-La Union, Mazzaron) that it is probably still illegal. In the Czech Republic, health and safety concerns have curtailed the activities of mine exploring clubs in recent years.
Hence it is very important to link up with other mining heritage enthusiasts in overseas countries that might be able to help put trip leaders in touch with the right people in their neck of the woods.
Welcome to our Mexican friend, Tayopa. I have really enjoyed exploring mine sites in your country, but woud have been unable to do so without the help of local friends and their knowledge of places, terrain and access issues.
Out of interest, I am thinking of organising a mining heritage trip to Peru and possibly Bolivia for later this summer.
