Why look for mineral deposits, just start digging the ground right under your feet, as in the game Hole Digger. You will be surprised how many valuable resources are where you go. Get into the ground with an ordinary shovel and delve into gradually, digging more and more different useful resources. Naturally, you can’t do with one shovel, but at first the tool can be improved by selling what you managed to dig. Next, you can buy something more powerful to get into the earth's bowels and dig up very valuable resources in Hole Digger.
