There are possible shafts to be explored, however the farmer would have to be approached, and I am not sure how he would take to the idea.
When the mines, commenced, a small village, was built,following the leadhills/ Wanlockhead examples, indeed some of the miners came from these villages, so it was inevitable that they would bring their working conditions with them.
A smelt mill was built on the site and the flue, can be followed.
In the 1960's the heaps were raided for road metal to make new forest tracks, and in the process I am sure damage to site's buildings, took place.
However the remoteness of the mine makes the site almost unique.
