Quarry

Improvement Structure Quarry
The Quarry is a unique structure that replaces mining by allowing miners to put their pickaxes into the Quarry mine for them. The Quarry consumes the pickaxes and in return has a small chance of generating Iron, Gold, Diamond, Emeralds and Tungsten Ore. The Quarry excretes cobblestone with a 1:1 ratio as a bi-product of the mining. Both the cobblestone and the precious minerals are stored in a single double chest. If the storage chest becomes full the structure will jam and stop working until the storage chest is cleared. It is important that the Quarry's storage chest is emptied often or it will not function.

How does the Quarry work
The Quarry is very simple to operate, simply select the pickaxes you wish to deposit it into the input chest. The Quarry will then start mining with it and sometimes, if you're lucky, precious minerals.

Currently, Enchanted Pickaxes do not have any affect on the quarry.

Mining Chance
The following chances do not take into account the diminishing chance caused by a lower chance item being generated. The Quarry randomly picks a number between 1-10000. This number is then checked against the lowest chance item first.

Quarry Upgrades
As of Civcraft 1.6, you can now purchase upgrades to the Quarry. These upgrades allow the Quarrys in your town to use higher levels of pickaxes: Stone, Iron, and Diamond.
