Mining Law is very closely tied to the taxation framework for the High King. By law, the High King is entitled to a small percentage of the output of each mine. This is part of the taxes paid by each Realm. Each Realm has what is known as a “Regalian right” over the mining activity within their borders, and this right is enforced by the High King's Law. That right allows the ruler(s) of each realm to claim a share of the output of mines within their territory, and assign ownership and/or administration as they see fit and/or their own laws provide. In some realms things are pretty straight forward - the mines are owned by the Monarchy, and nobility appointed to run the mines make take a share of the profits. In other realms, things get pretty complex - feudal rights, political appointments, family favors, debts and mines being used as collateral, among other things have led to a complex web of ownership.
