A copper deposit shows you its crown first: a green-streaked back rising through the forest floor, with the rest of its shape still hidden by soil. It is tempting to shave that visible surface and move on. Follow an edge downward, though, and another working face may emerge. The useful discovery is the shape of this particular deposit, not a secret number of swings that makes every outcrop burst.
Start with a way out of the excavation and somewhere to put the yield. Then expose the copper in passes. Undermining can destroy unsupported sections, but a rock that looks suspended has not necessarily lost the support the game checks. If the remaining deposit refuses to collapse, you can still mine the reachable faces and leave with a worthwhile load.
Give the place a route home
Before the first cut, walk around the outcrop. Pick a recognizable arrival point: the low side facing the coast, the gap between two boulders, or the open slope toward your smelting base. Mark the deposit and the intended exit on the map if you use one. Those landmarks become more useful after the original mound has turned into a rim above your head.
Look beyond the copper itself. A slope can offer a gentle approach on one side and an awkward climb on the other. Water may put a limit on where you can stand. A nearby boulder might matter less to the first pickaxe swing than to the cart you eventually hope to bring through. Choose the accessible side first, with room to turn and retreat, and keep that approach open as the dig changes.
Clear the obstacles that obstruct that route. You don't need to remove a mathematically perfect ring of forest before finding out how much room the deposit needs. If the cart must wait on firmer ground, choose that staging point now and leave a short hand-carry route between it and the excavation. The mine and the loading area can be different places.
Bring a pickaxe you can keep working
The Antler Pickaxe is enough for a standard copper deposit. Its base tool tier meets copper's minimum tier; a Bronze Pickaxe improves the tool rather than unlocking a rock that the antler could never touch. The practical choice is how much digging you intend to do and where you can maintain the equipment.
| Tool | First craft | Crafting station | Base pickaxe damage | Base durability |
|---|---|---|---|---|
| Antler Pickaxe | 10 wood, 1 hard antler | Workbench, level 1 | 18 | 100 |
| Bronze Pickaxe | 3 core wood, 10 bronze | Forge, level 1 | 25 | 120 |
These are the first-craft recipes and base tool values. An upgrade requirement is a separate question from the materials for making the first pickaxe. An upgrader-only material is not part of the Bronze Pickaxe’s first-craft shopping list. The damage column describes the unmodified base equipment; it is not a promise of a fixed number of swings or an explanation of which neighboring sections will lose support. Inspect the pickaxe you are carrying, rather than treating its name as a guarantee of the work it will finish.
A second pickaxe can be a sensible companion on a longer trip. So can a short journey back to an existing station. Choose between those arrangements before the first tool breaks, while the question is still about the route rather than how to leave a pit with an unfinished load. Bring food and the ordinary means to deal with an interruption; the copper will wait while you make the work area usable again.
A workbench costs ten wood. A forge is a larger local commitment: four stone, four coal, ten wood and six copper, with a workbench needed for placement. Build around the trips you expect to make. An elaborate camp beside a deposit you will visit once may be less useful than a modest staging area on a route you already travel.
Trace an edge, then decide where to dig
Open one side of the deposit before committing to a complete trench. Dig beside a visible copper face and inspect what the cut reveals. Follow the newly exposed surface while leaving enough ground to stand and enough room to turn toward the exit. You are learning where this rock continues, rather than excavating an imagined sphere whose outline you decided in advance.
Where the ground allows it, work around another side and compare the two faces. A low approach may uncover copper conveniently; the opposite edge may require much more digging for another small working surface. Keep asking whether the next cut gives you access to ore. That question is more useful than making the entire rim equally deep for the sake of a tidy pit.
Preserve a ramp or another approach you can actually use. Test it from below after the excavation deepens, not just from the rim before you start. Leave the cart on accessible ground if the route into the pit is awkward. A little extra hand-carrying is easier to plan than recovering a loaded cart from the wrong side of a steep cut.
Why a floating section can remain
Copper is divided into damageable sections. Its support check uses collider bounds and nearby qualifying colliders; the visible outline alone does not describe that calculation. Support can also pass between parts of the same deposit. A narrow-looking connection or a gap that appears clear from one angle therefore isn't proof that every remaining section is unsupported.
When a mined section breaks, the deposit can recheck support and destroy sections it finds unsupported. That is the collapse worth looking for. It is not a promise that digging one particular trench width, breaking the lowest visible point or tapping a seemingly airborne rock will remove the whole mass at once.
If the deposit hangs above the cut, circle it where you can do so safely. Inspect the other edges and the ground beneath reachable sections. Remove a small accessible section and watch the response. If a larger part breaks, collect the drops and examine what remains. If it stays, continue mining the faces you can reach; don't turn a stubborn remnant into an obligation to dig indefinitely.
There is a useful stopping point before the perfect excavation. If water covers your footing, the exit has become difficult or the next face requires a great deal more earthwork, compare that effort with another accessible deposit. Leave a map note about the remaining side. Returning with a clearer route is a better prospect than finishing the session stranded beneath the last bit of copper.
Collect the yield in passes
Destroyed sections can produce stone as well as copper ore. The drop table makes weighted selections, so a particular broken section is not a promise of a particular copper count. A dramatic collapse also does not establish a universal total for the whole deposit. Judge the trip by what you have collected and can transport, not by an expected haul copied from somebody else's pit.
Make collection part of the excavation rhythm. Clear the loose material from a working face, carry a load to the staging point, then return to the next cut. This gives you a reason to check the exit, tool condition and remaining supplies before another part of the mound disappears. If you're working with friends, one person can handle the short haul while another mines, provided both keep the same route open.
An ordinary portal costs twenty fine wood, ten greydwarf eyes and two Surtling cores, and needs a workbench for placement. It can help with travel to a station or fresh supplies, but under ordinary portal restrictions copper ore cannot pass through it. Keep an actual ore-hauling plan even when the portal makes the return journey feel wonderfully short.
Test a cart route before loading it. Walk the turns and check the places where a stump, rock or uneven edge narrows the path. If the deposit sits above the staging point, make sure you can reach the containers without committing to a drop you cannot climb back from. A route that works for the first handful of ore should still work when you're tired of looking at the same rock.
Back at base, a compact smelter and kiln layout can make processing easier. Leave room for the arriving load rather than using the last clear approach for another building. The forest has supplied the copper; the remaining job is to bring it through the gate, with a usable path left behind for the next visit.
