Yeah! Some rooms allow you to dig the floor with the shovel, or mine the walls with the pick. It will say this in the descriptions when you choose the room or focus on the map. In the room, go to your inventory and browse the tools. You will hear a chime when you can use the tool. That's how you get most of the gold. Bring it to Citrine and permanently unlock the next category of rooms :).
