Old Gossip
Rudall told Christopher that the mine might have been a gold mine made decades ago. The gold stayed untouched when he started to look at the walls. There was abundant evidence that the workers did not deliver the work and opted to leave the mine. What might be the explanation? Normally, if you know that gold can be collected, you will not stop until you can get it.
Abandoned Gold
Rudall then did explain that there have been several extraction assumptions throughout most of the turn of the century, even though he had very less understanding of specific gold mines earlier. So why did the laborers finally leave the mine and simply leave far too much gold? None of it was useful, but Christopher wanted to know the truth of the matter.
