Getting a current map of mine locations for any section can be a challenge.
This can make it difficult for you to find then claim your own mine, much less know where to dig.
To get make such a map you have to determine the mines in any section, then go to BLM to make copies of their maps when they submitted their paper work.
Then we convert all this from township and range coordinates system to GPS. Creating a file for your device letting you know where all the current mines are.
