Mineral seal

Estimated value:

1 000 000
It is placed in Mineral Warehouse, strengthening the structure and reducing mineral erosion.
It can be found in any expedition with Science Vessel (for humans), Queen (for xerjs), and Investigator (for tosses), with a probability proportional to the expedition's time in days.
Once per hour, an active Mineral Sealer has a 0.125% chance of breaking.
