Can't be destroyed
Ore Mines are the main resource structure in Command & Conquer: Red Alert 3 . They provide an infinite number of ore, slowing down to a trickle once the mine is "depleted". In campaign mode, ore mines usually provided as much as 30,000-90,000 due to the difficulty of the levels. In skirmish/multiplayer mode, the number of ore per mine is at 30,000. Ore collectors would come and let the mechanized crane of the ore mine drop ore onto the cargo bay while turned in the ore mine port- which would be dumped at an Ore Refinery. Ore mine structure cannot be destroyed, even by superweapon (but any miner caught while standby on its port automatically get damage). Ore mines also imune from Spy and Shinobi harrasement. They are exist inland and in water bodies as well.
