The Copper Boulder is a boulder you break with a pickaxe to get Copper. You need a Flint Pickaxe for it, because the Stone Pickaxe mines only Flint and Stone. When you aim at a boulder, the prompt shows its name with a pickaxe icon. If that icon is red and crossed, the tool in your hand cannot break it, so swap to the Flint Pickaxe before you swing.
The map has 136 Copper Boulder spots, and they gather most thickly around Rift Cave with 17, Landscar Cave with 13 and Crater with 11. Smaller clusters sit near Improvised Radio Tower, Shattered Convoy and Shallow Rift. Another 69 spots lie out in the open, away from any named place, so you can pick up Copper while crossing open ground. Copper goes into crafting Copper Ingot.
