For Mines, the rules state:
...at the end of each phase, the player recieves 1 Silverling from the supply for each mine in his estate.
And in the Game End section:
The game ends after the fifth phase has been played through to completion.
My reading of these rules are that after the final round of phase E players would receive 1 Silverling for each mine they have and then the final scores would be counted. So effectively you'd get an extra point for each mine you have at the end of the game.
Is this correct, incorrect or something ambiguous where you could just agree on the interpretation before the start of the game.
