Graveyard Keeper 2: How to Automate Stone Production

Stone gets used steadily in Graveyard Keeper 2, from early building projects to mid-tier recipes. You can avoid repeated trips to the Quarry to mine more by putting undead workers in charge. Once set up, the system mines the stone, processes it, and delivers it underground to your Yard automatically.

Quick answer: Place a Zombie Stone Quarry beside the Quarry cliff and assign a pickaxe-wielding zombie to it. Add a Zombie Supplier Station and a Porter Station, staffing both with a zombie. The porter delivers the finished stone to the Yard’s Stone Stockpile.

What you need before automating stone

The system depends on an inexhaustible stone node on the Quarry cliff, south of the Yard and beyond the Inquisition Base. Since mining it has no limit, you won’t need to gather loose rocks around town that don’t respawn. The rest of the setup transports stone from this node back to your home.

You must research two entries and get your workers ready before the workstations become available in the build menu. Research makes the option available, but you’ll still need to provide the materials and build the structures yourself.

The Old Mine remains locked until you make progress in the early story. Finish the opening quests for both NPCs at the forest Refugee Camp to unlock it; zombie extraction and crafting technologies are available in that tunnel.

Clear the underground route to the Quarry

Go down to the basement under your home, enter the Writing Basement, and continue toward the Factory. You’ll find rubble blocking the tunnel; clear it to connect the route with the Quarry and Old Mine.

Inside the Old Mine, walk to the northern end of the tunnel and clear the rubble blockage there. Clearing it unlocks the zombie mining and crafting abilities you need for the chain.

With the blockages gone, follow the Old Mine corridor north past the existing Porter Station and out to the surface Quarry entrance. This corridor becomes the highway your porter uses to carry stone home, so keeping it open matters.

Unlock the Building blueprints

Open the Tech Tree from the top menu and choose Building. Spend points to research Blueprint: Zombie Stone Quarry and Blueprint: Porter Station. With both unlocked, the quarry workstation and porter become available in the build menus. You need no other research in this branch to transport stone.

Build and staff the quarry stations

You need three zombies on separate tasks to automate stone completely: one mines, while the supplier and porter manage transport. If stone collects at the Quarry and never reaches home, check whether a transport station is missing or lacks a worker; the miner isn’t the cause.

Station	Zombie role	What it does
Zombie Stone Quarry	Miner (needs pickaxe)	Extracts raw stone blocks from the cliff node
Zombie Supplier Station	Supplier	Breaks blocks down and moves stone into chests
Porter Station	Porter	Hauls processed stone through the corridor to the Yard

Open the build menu at the Quarry cliff and set a Zombie Stone Quarry beside the mining node. Assigning a worker to this workstation lets it extract stone automatically.

Put a zombie to work at the Zombie Stone Quarry and equip it with a pickaxe. The zombie won’t mine without the tool and will remain idle on the scaffolding, so be sure to equip one.

Set up a Zombie Supplier Station close by and put a second zombie to work there. Rather than mining, this worker cuts the raw blocks and places the processed stone in the nearby storage chests.

Build the Porter Station and assign a third zombie as the porter. In the Porter Station’s “Items for transport” screen, toggle whether the porter carries Stone, Marble, or both, then confirm the porter is assigned. This zombie physically carries the finished blocks along the cleared corridor to your base.

You can place up to two miners on the extraction cliffs at once, and the same layout mirrors on the right side of the Quarry for automated Marble production.

Confirm stone is delivering to the Yard

Back at the Yard, inspect the Stone Stockpile. The porter’s trips from the Quarry should add stone to it automatically. Watch the counter rise to confirm deliveries are coming through, without hauling stone yourself. For example, a count moving toward 20/20 shows the loop is working.

The Stonemason’s Workbench can use stone stored in the Yard’s Stone Stockpile directly. Queue Piece of stone or Polished Stone there, and the bench takes what it needs from the stockpile without requiring you to put anything in your inventory. Once the miner, supplier, and porter are all assigned, stone continues arriving in the background as you handle quests and construction.
