In order to manufacture products in industrial production facilities, each product requires specific raw materials. To produce these raw materials, suitable land must first be purchased, and then a mine must be established on this land. The lands are refreshed every hour. With each refresh, 1000 lands are added, completely updating the list.

Once the mine is established, different raw materials can be produced depending on the type of land.

There are 15 different types of land in total:
coal deposit, silica sand land, iron ore deposit, silver mine land, gold ore land, forested land, oil deposit, aluminum deposit, lithium deposit, chemical material land, lead ore land, copper deposit, zinc deposit, diamond mine land, ruby mine land, and emerald mine land.
