Minerals
The whole story behind MotherLoad is the search for the extremely rare wealthonium, so minerals play a huge part in the game! You also need minerals to get money, which is used for buying fuel, repairing your machine and upgrading your machine.
All the minerals in the game are shown on this page with their attributes. Also shown are items that can be found in the soil whilst digging. While these items are not minerals as such, they still give a good amount of cash.
You still mine items in the same way as you would minerals, except there is on major difference: to get money from minerals, you need to take them back up to the surface for processing, but with items you get instant cash.
The minerals and items in the table are listed in rarity, as you go down the list the more rare that item/mineral it is, and the more money you get for finding it. You can carry more minerals with a bigger Cargo Bay.
Please note: the "Where Found" column in the table refers to where the minerals are commonly found.
