Go along with the North Depths game somewhere to Antarctica to start mining there. Initially, a building has been built that will allow you to start prey. You will see it on the right on the screen, and on the left click on the field to lay tunnels and look for natural resources. Click on them and below on the panel you will see replenishment of your budget both in obtained resources and in the breakdown of ice blocks. Having accumulated enough, you can start building additional buildings and improve them so that the production is faster and more modern methods in North DeptHs.
