Clan Quarry (mining quarry) - what is it, how do I unlock it, who can build it, and how does it mine ore, who can collect the resources?

The Clan Quarry is a clan automation station that mines stone and ore, including high quality metal ore, so your clan doesn't have to farm it by hand.

Unlocking it. You unlock it in the clan progression tree — the clan leader or an officer activates it there. It needs the previous progression level and enough clan currency (payable with coins). Activation takes time and can be sped up for an extra cost.

Placing it. Only the clan leader or an officer can place it, and you have to be in a clan. A clan can have one station of each type on each server — stations are not shared between servers.

Who can use it. Any Leader or Officer of the clan can refuel it, switch it on and off and take out the resources it mined. Soldiers can't use it.

Fuel and running it. The station runs on Fuel Bottles (one slot). Switching it on reserves clan currency for all the fuel you loaded; whatever isn't used is refunded when you switch it off. While it's running the fuel slot is locked — you can't add or remove fuel until you switch it off. Use the button in the station's panel to switch it on and off, not the switch on the model. It stops by itself when the fuel runs out or the storage fills up. After a server restart the station keeps working as long as it has fuel.

Collecting. Mined resources collect in the station's storage. That storage is take-only: you can take things out of it, but you can't store anything in it. The higher your clan level, the more it produces and the shorter each cycle. A new level applies while the station is switched off.

Protecting it. The station needs a Repair Cupboard nearby — simply having one in range is enough, and it doesn't consume upkeep resources. Without one, the station decays and is destroyed within hours. Enemies can damage and destroy it, and it can't be locked. Anyone authorized at the Repair Cupboard next to it can repair it or pick it up; with no cupboard, only the player who placed it. It can only be picked up when the fuel slot and the storage are empty. If it gets destroyed, the fuel and everything stored inside drop on the ground.
