Digging up minerals and bringing them up to the Mineral Processor 3000 is your main source of income. Different minerals are worth different values, with the less valuable found abundantly and the more valuable found in increasing quantities the deeper you go.

Minerals have weight, with the more valuable ones weighing more. The mining pod itself also weighs 1980 kg. Depending on your engine your pod will only be able to fly up at speed with a certain amount of weight, slowing down as you get heavier, until the point at which your propellers can only slow your descent. Even with the best engine, it is very difficult to take off with 5800 kg, and impossible above roughly 6200 kg. You can discard minerals by clicking on them in the inventory.

Any square with a mineral can be drilled in to collect it, and they never have gas pockets, making them safe.

^This is based on when you may expect to start seeing two of that mineral in one screen, a rough benchmark for being "common".

*Displayed in-game as ?XXXXX ft. with numbers flashing, which happens beneath -5800 ft.

There is a large degree of randomness in mineral spawning, and these estimates are based on realistic scenarios. You may discover them out of order, or find Amazonite at -3000 ft (there are even unverified reports of it spawning near the surface), but they are too rare to be realistic.

*These are Level 1 base values but prices are reduced by the number of times you defeat Satan, e.g half this value for Level 2, one-third for level 3. For more information, click here
