Every NFT in this category, marked with an iron symbol, will bring different resources. Some NFTs will bring in addition coal, gold, diamonds, or other rare resources.
Having your own land will bring you passive resources if the NFT provides a bonus for this category of resources.
Mined resources will be used as materials to craft various things from your discovered blueprints, and other purposes.
