During the tutorial of the game, there are multiple things you can pick up before the search for gerald truely starts. One of those things is the gold ore. If you search once and cant find it, search again!
I am still unable to unlock scene 10, but I was able to unlock scene 9. You unlock scene 9 by maxing our your relationship with Lozran, completing all of the games quests, and finally saving Gerald . Just try to complete all the quests, keep flattering Lozran, do one of his first scenes with him, then, once everything is done and Gerald is gone, go back to the inn and speak to him.
