"A very big osmium mine that produces massive ore manually on click."
The Osmium Excavator is a Super Rare-tier mine. This is the most powerful excavator in the game, with an ore value of $40,000. This works well with cell furnaces because of it's high ore value.
- The ore pruduced from the Osmium Excavator is large enough to get upgraded by a Morning Star without having to be shot through it's hoop.
