Isotopes
Isotopes are a rare kind of mineral. You will begin to mine isotopes at around 20 to 30 kilometers depth.
Uranium
Uranium is the most common isotope, and the third rarest resource to be mined. It is used to craft Cargo Bay 3 and Basic Nuclear Engine. It will start occur at level 24.
Uranium 1: $100 / unit
Uranium 2: $2,000 / unit
Uranium 3: $50,000 / unit
Plutonium
Plutonium is the second rarest isotope, and the second rarest resource. It will start occur at level 34 and achieve maximum at 54 (upgrades and miners still increase the amount you get, but not depth)..
Plutonium 1: $1,000 / unit
Plutonium 2: $20,000 / unit
Plutonium 3: $500,000 / unit
Polonium
Polonium is the rarest isotope and rarest resource. It will start occur at level 55 and achieve maximum at 84 (upgrades and miners still increase the amount you get, but not depth).
Polonium 1: $5,000 / unit
Polonium 2: $200,000 / unit
Polonium 3: $50,000,000 / unit
Nitrogen
Nitrogen 1: $50,000,000 / unit
Nitrogen 2: $150,000,000 / unit
Nitrogen 3: $300,000,000 / unit
Einsteinium
Einsteinium was the rarest isotope and rarest resource.
Einsteinium 1: $5,000 / unit
Einsteinium 2: $200,000 / unit
Einsteinium 3: $50,000,000 / unit
- Einstenium was replaced with Polonium in patch V0.25 as Einsteinum cannot be mined whereas Polonium can be
