# Mines * Last but not least, there are **mines** specific to each land, which can be extracted using the worker robot. In each land, there are certain mines that players must extract from them with their explorer robot. Then they can store the extracted [resources](/whitepaper-space-six/nfts/resources.md) in their warehouse. There are different amounts of mine reserves on different lands, such as gold or bronze, so that the more valuable the [land](/whitepaper-space-six/nfts/lands.md), the more mine reserves there are. As the mines are upgraded, their reserves will gradually increase. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
