Overview

The Mine is an essential Resource Gathering building. It has to be placed over at least 1 vein of Copper Ore, Coal, or Salt. The mine is the only way to make use of these veins.

The Mine is unlocked at level 2.

Whether you get Copper Ore, Coal, or Salt charges and their amount depends on the number and resource of veins covered by the Mine.

12 Pipes/ 4 Parts/ 10 Tools +
15 Planks/ 15 Bricks

Strategies

Make sure to build a Small Warehouse next to the Mine to cut down on the time workers spend hauling resources.
There are virtually no scenarios in which the Minecart upgrade outperforms Pit Ponies. ^[1]
At full citadel, with optimal warehouse and hearth placement, miners on average spend 22.4 seconds working in the mine, 3.2 seconds taking break, and 2.5 seconds hauling per every charge.^[1]
The Sea Marrow produced as a bonus resource in Salt mines can be used to alleviate fuel shortages or be used to open Abandoned Caches when Stone isn't available.
The Royal Woodlands do not spawn mining veins by default. Unless you can find a Rainpunk Drill, plan on obtaining Copper Ore from Clay deposits and burning Wood or Sea Marrow for fuel.
