"One canary for every miner, these mines will be dug deep into the earth to find precious minerals. The mine produces metal, which can be used in a myriad of places."
Mine[ | ]
A Mine is a Stronghold structure that produces Metal over time. To transfer the Metal at the Mine to the Stronghold Coffer, you must tend it by interacting with the sign at the plot is is built on. Upgrading the Mine increases the rate of production of Metal and the capacity of Metal the Mine can hold. A Smelter's Yard increases the Mine's production rate and capacity.
The first Mine is built at the "Stronghold Height" plot. A second Mine may be built at the "Maiden Lane's Hollow" plot.
