Do solid minerals found within land become part of the sale when the land is sold?

Primary text

Solid minerals existing in the land, such as gold, silver, iron, copper, and lead, enter into the sale and ownership is established through the ownership of the land containing them, as they are considered parts of the land, similar to its soil and stones. However, the mineral of gold cannot be sold for gold, and the mineral of silver cannot be sold for silver; selling them for a different commodity is permissible.
