There is still a chance of all 3.


 * Breaking one Demon Altar is all that is required to place multiple, but rare, pockets of cobalt ore in your world. For each Demon Altar you break thereafter, more pockets of Cobalt ore appear in the world.

This applies to the other ores aswell im guessing,but it's completly random when you break the Altar.
