That's a nice report. One thing though, the gold bar from here and Ogofau and Marina mines that was used for royal wedding rings was apparently used up by around 1980 and replaced by a bar from Gwynfynydd mine - that was in production around then (and was a fine explore).
Thanks for the info man, The remaining 1KG of gold from Gwynfynydd that was presented to the queen was apparently on display in south wales somewhere before Christmas but cant remember were...thanks again
