As I said in my post a few months ago, I was up in the area [Minnions, Cornwall] around 1994 with one of the Archaeologists From County Hall at Truro, while I was a member of a Tinworkings Research Group. We looked at the tinworkings all over the area, covering times from the Medieval to the 1800's. The ore was streamed in the earlier times and mined in the later times . The archaeologist taking us around took us up onto the Cheesering to look at Stowe's Pound and also showed us this stone , which I think he said was the Jubilee Stone, done by the miners to comemorate one of Victoria's jubilee's. It apparently plays God Save The Queen in small bangs made by putting dinamite in the small indentations.
Hope that is helpfull to all.
Peace Lubin.
