You are now the person in charge of this mine. Arrange your workers to mine. Although you have nothing now, as long as you arrange your workers reasonably, I believe you will become a mining tycoon! Earn a lot of money!

Click on your worker to produce resources for selling. You can then use your elevator to transport the rocks to the ground, where they will be transported to the warehouse. As you get further in the game you can dig deeper and unlock mine shafts that generate more money.
