The Junkyard - a third dig site: 50 layers under Rudy's junkyard, with brick, grey gravel, scrap and crushed cars

Scrap - scrap blocks pay a little every time you hit them, not only when they break

Crushed cars - only the pickaxe breaks them; rigs and Biscuit leave them to you

The Old Quarry - a fourth dig site: 60 layers of limestone, dark basalt, silver and coal under an old stone quarry

TNT crates - break one and it blasts every block around it, and sets off other crates nearby; rigs keep away from them

Story - Uncle Rudy has new radio lines for both sites, and each one has something at the bottom

Old Bones' map - the last two pieces of the first map
