Hello derrickman,
the conveyor was in very regular use up until a few years back
my mother was always moaning about the strange whirr that seemed to come from the mines-as she put it!Miller Buckley.l'd forgotten all about that name,and l think the conveyor was finished in the late 80's from memory.The ropeway was all but
completely dismantled at that time,some said it all went to Russia,but l don't know for sure.The old cable cars looked very odd in such rural surroundings,some of their supporting pylons were very high.There were,l believe,3 "corner stations" that looked like meccano gone mad,but very compelling to watch.Some pics of the system,both ropeway and conveyor,are on the flickr photo site.
