The team now faces 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 its 300-year-old tunnels! Since its 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!
