"Holy mother of berezaa this mine is giant. It's so big, the builders had to make a built-in ladder."
The Massive Iron Mine is a Rare-tier massive mine. It is the cheapest, and first, massive mine in the game. It can be useful for new players, but its ores can get stuck inside of some upgraders (e.g. Rainbow Upgrader). The Massive Iron Mine is MUCH larger than the Yuge Iron Mine, despite the mine's description stating otherwise.
- Its ore size is the same as all the other massive mines, 4x4x4.
