To explore the number of underground resources, the player should send his worker to this plot to make the exploration. If someone has already made the exploration before, the information about resources on this plot will be visible to all players. Resources are randomly distributed along the map. The amount of wood and stone is visible right from the start so you only need to explore for the underground resources. You can explore all the deposits, except for gold, with bare hands. The amount of resources on the plot is defined in the moment of its exploration and recorded into the blockchain.
To explore gold deposits, specific tools are required: pickax and pan.
