Silver Mine

"'A silver mine that produces ore slightly better than iron but fires much more rapidly'"

Overview
The Silver Mine is a Common-tier mine. It has a very high drop rate for low level mines. It is the seventh fastest dropper in Miner's Haven (beaten by the Spookmaster-5000, Newtonium Mine, Atomium Mine, Spitfire Iron Mine, Wubium Mine, and the Breech Loader).

Trivia

 * Due to its fast drop rate, it could be considered the best mine to use in early-game RP farms. With better research furnaces however, it is usually necessary to use upgraders, as the ore value is too low (a Cursed Ore Purifier is useful for this).
