TotK Abandoned Mines: All 10 Forge Constructs and Trades

The abandoned mines of the Depths in The Legend of Zelda: Tears of the Kingdom are where Zonaite was once mined and refined. Every mine has a Forge Construct that turns your Zonaite into Crystallized Charges and Zonai Charges, and a Steward Construct that hands out Schema Stones. This page lists all ten mines, the Forge Construct’s rates, and what else each mine has.

How many abandoned mines are there, and where?

There are ten, most of them named after the town or region on the surface above. The map and the table come from the game’s placement data; each point is that mine’s Forge Construct.

Click “Show on map” to move the map above to that spot.

The “How to get it” column names the Lightroot nearest each Forge Construct; once it is lit you can warp straight there. Statues along the way in the Depths often face toward the mines, so following them works too.

What does a Forge Construct trade?

In the game’s data, all ten Forge Constructs in the mines (and the one in the Mining Cave on Great Sky Island) trade the same things at the same rates:

Large Zonaite is the one to chase: 3 of them buy a charge worth 20, while 3 ordinary Zonaite buy only 1. How the battery grows and what it costs: battery upgrades. Where to mine the most ore: zonaite farming. What Zonai Charges get you at a dispenser: Zonai devices.

• Wake it first. Forge Constructs in the Depths start out dormant. Walk up and activate one with your right arm; it says “Authorizer verified.”
• Stock is limited. When the shelves are empty it says “That is all I have on hand. Please wait until I have processed more.” Each one in the Depths reportedly stocks 30 Crystallized Charges and 5 Large ones at a time.
• Bring a full bag and visit several. When one runs out, move on to the next mine.

What else does each mine have?

Schema Stones. The Steward Construct at each mine gives one. The stones at the Central, Gerudo and Lanayru mines come after you beat Master Kohga there. At the other mines, if you have not been to the Great Abandoned Central Mine yet, the Steward Construct sends you there first: “I have something for you. But I do not think you are ready to receive it. Please visit the Great Abandoned Central Mine and return here afterward.” Come back afterwards and it hands the stone over. All 12 Schema Stones are on the schematics page; how to use them is under Autobuild.

Bargainer Statue. Of the ten mines, only the Great Abandoned Central Mine has one, where Poes buy armor and materials; see Bargainer Statues. Grand Poes often sit up high around the mines; see Poe farming.

Which mines does Master Kohga show up in?

The main quest Master Kohga of the Yiga Clan takes you through four mines: the Great Abandoned Central Mine, the Abandoned Gerudo Mine, the Abandoned Lanayru Mine and finally the Abandoned Hebra Mine. The quest log sums up the end: “Your final showdown with Master Kohga at the Abandoned Hebra Mine resulted in the revival of the ultimate weapon—a giant construct. You managed to defeat it.” Once the Yiga are gone, the mine’s Steward Construct thanks you: “Thank you for driving out the trespassers.”

How to win all four fights: Master Kohga. The Yiga Clan’s other hideouts: Yiga Clan.
