Gold Mine Ability

[operation3000]

Hello
Here is my probleme:

I need a way to make unit unable to harvest gold from gold mine untill they built a building on them. when the building has been built, worker can harvest gold.
Another problem: I need also a way to upgrade this building. Example : first upgrade will allow workers to harvest gold in half time and it can be upgraded again to allow two workers to go inside at the same time.

please for helping me

PS: when i said that worker will bet allowed to harvest gold, they will harvest it like Human and Orc, not like Undead or Nigh Elf. ok? thanks again

First off, do a similiar structure as Haunted Goldmine, which need a mine to be built on. Then add the goldmine ability on that mine, so the one you build on doesn't have one but the one that is built has. After yuo make new goldmines that is being upgraded(I think this works...) and make new abilities for them and so on.
