In a clash of clans war base what is the best position for gold/elixer mines? [closed]

Because you do not lose resources from being attacked in a war, there is no reason to defend the collector and storages. The storages have a lot of health and a bigger radius than the collectors, so putting storages outside of your walls in weak spots of your defences would be ideal. Also, putting the non-defense buildings, except for things like the town hall that actually matters, in places so that the attacker cannot easily lure out the clan castle troops would be an effective strategy. Another choice is to use these buildings to increase the distance between the "red line" and your walls to allow your defences to get extra hits in and kill wall breakers easier.

You can't lose any resources, mines are a kind of useless except that they can take some damage and hold up enemy troops in clan wars. Almost everyone normally place the mines outside their base for that reason.

The storages have high health points, use them to hold up enemy troops on strategic places in your base.
