It would be both a bomy and human job.

There should be these mines, and to enter you'd have to pay a certain amount of gralat for a set amount of time.
(20g=5 minutes, 30g=10 minutes, etc)
In the mines, you can dig, and occasionaly you dig up stuff.
There would be fossils and other things that you only sell to an npc at entrance to mines.
But you could also dig up iron, gold, durbies, diamonds, crafted or non. You could keep these or sell them to the npc.

There would be different types of fossils with different values
for example, a T-rex skull worth 100g (very rare) or a Triceratops tooth (10g)

Prices/value of stuff could vary of course. I'm just using those numbers as examples.
