From level 7 town hall you don't get any more gold or elixir mines until level 10. If you are at level 7 and have all of the mines at level 11 and are upgrading all of your walls from level 6 to 7, then assuming you do not attack and are not attacked, it will take 80 days. That is the 200,000 gold upgrade. At level 8 you upgrade for 500,000 gold and still have the same number of mines but things are more expensive. Then you get to level 9 town hall and still no more mines to be able to buy things. If you could add more mines during that stretch then it would be very nice.
