Permafrost Iron & Scrap Pickaxe Locations

In 7 Days to Die, iron ore in the permafrost biome is found in the same gravel and iron nodes as elsewhere, but the ground is harder and requires a better tool. You need at least a stone axe or a basic iron pickaxe to mine it effectively; a scrap pickaxe works, but it is slow and will break quickly. This article explains where to find iron in permafrost, how the scrap pickaxe compares to other tools, and how to mine efficiently.

Formula

The calculator works out your mining rate: blocks per minute = blocks mined ÷ time spent (minutes). The second output gives the inverse: time per block = time spent ÷ blocks mined. Both use the same two inputs. The default values assume you mined 50 blocks in 10 minutes, which gives 5 blocks per minute and 0.2 minutes (12 seconds) per block.

Worked Example

Using the defaults from the block:

• Time spent: 10 minutes
• Blocks mined: 50
• Blocks per minute = 50 ÷ 10 = 5 blocks/min
• Time per block = 10 ÷ 50 = 0.2 min = 12 seconds

So with those numbers you mine one block every 12 seconds on average. If you switch to a slower tool, the time per block goes up and the blocks per minute goes down.

Where Iron Spawns in Permafrost

Permafrost biomes (the snowy, frozen tundra areas) have the same ore generation as other biomes. Iron appears in two main forms:

• Surface gravel patches – small clusters of grey rocks that yield stone and a bit of iron when broken.
• Underground iron nodes – large, dark-grey blocks with a metallic sheen, usually found a few blocks below the surface or inside caves.

You will also find iron by mining any stone block, because stone has a chance to drop iron fragments. However, the highest yield comes from dedicated iron nodes. Look for the distinctive grey-blue blocks with a rough texture; they are often mixed with coal and nitrate in the same underground layers.

Why Permafrost Is Different

The permafrost biome itself is not harder to mine than other biomes – the ground is the same dirt and stone. What makes it feel different is the cold. Exposure to freezing temperatures drains your health unless you have proper clothing or a heat source. That means you need to bring warm gear, campfires, or coffee to avoid dying while you dig. The cold does not slow your mining speed directly, but it forces you to take breaks, which reduces your overall blocks per minute.

Scrap Pickaxe vs. Iron Pickaxe

The scrap pickaxe is the second tier of pickaxes, crafted from scrap iron. It mines faster than a stone axe but slower than an iron pickaxe. Here is the practical comparison:

• Stone axe – slowest, but free and easy to repair. Good for breaking surface gravel.
• Scrap pickaxe – moderate speed, decent durability. Works for iron nodes but will wear down noticeably.
• Iron pickaxe – faster and more durable. The standard choice for serious mining.
• Steel pickaxe – fastest, but requires steel and a high level to craft.

If you only have a scrap pickaxe, you can still mine iron, but expect to repair it often. Carry a repair kit or extra scrap iron.

How to Get a Scrap Pickaxe

You can craft a scrap pickaxe at a workbench or directly in your inventory if you have the recipe. The recipe requires:

• Scrap iron (about 10–15 pieces)
• A workbench for the better version, or just your crafting menu for the basic one

To get scrap iron, break down metal objects like cars, pipes, and old machinery with a wrench or a stone axe. You can also find scrap pickaxes in loot containers, but crafting is more reliable.

Tips for Mining Iron in Permafrost

1. Wear insulated clothing or carry a torch to avoid freezing.
2. Dig down in a spiral staircase pattern to reach underground nodes safely.
3. Use the surface gravel patches to get early iron without digging.
4. When you find an iron node, mine around it first to expose all sides – this lets you break it faster.
5. Repair your pickaxe before it breaks; a broken tool stops all progress.

Common Mistakes

• Using a stone axe on iron nodes – it works but takes many hits and breaks quickly.
• Ignoring the cold – you can die from exposure while mining, losing all your loot.
• Not repairing your scrap pickaxe – it has low durability, so carry repair materials.
• Mining straight down – you can fall into a cave or lava; always dig at an angle.

Alternatives to the Scrap Pickaxe

If you cannot craft a scrap pickaxe, the stone axe is your fallback. It is slower but free. Later, the iron pickaxe is a direct upgrade. You can also use explosives (like pipe bombs) to clear large areas, but that is wasteful for just iron. The best long-term solution is to invest in the Miner 69er perk, which increases your mining damage and reduces tool wear.

Frequently Asked Questions

Can you mine iron with a stone axe in permafrost?

Yes, but it is very slow. A stone axe can break iron nodes, but it takes many hits and the tool degrades fast. It is better to craft at least a scrap pickaxe before mining large amounts.

Where exactly do iron nodes spawn underground?

Iron nodes are found in the same layers as stone, usually between 5 and 30 blocks below the surface. They appear as large grey blocks with a metallic texture, often near coal and nitrate deposits.

Does the permafrost biome have more iron than others?

No. The ore distribution is the same across all biomes. The only difference is the cold, which makes mining more dangerous but not more rewarding.

How do you repair a scrap pickaxe?

Use a repair kit or scrap iron. Open your inventory, select the pickaxe, and click the repair button. You need the required materials in your inventory.

What is the fastest way to mine iron?

Use a steel pickaxe with the Miner 69er perk maxed out. Also, drink coffee or take other buffs that increase mining speed. Explosives can clear large areas but are not efficient for small nodes.
