Silver Mountain Mine The team now face an investigation unlike anything they\'ve attempted before; to descend into the darkness of a 17th century silver mine. Llywernog Mine - now known as the Silver Mountain Experience - is now a tourist attraction for those brave enough to venture down into it\'s 300-year-old tunnels! Since it\'s opening both staff and visitors have experienced many unexplainable events, so the site\'s owner was eager to see if the team could document any evidence to support these claims!
