The Coin Mining Den is a Rare key in MW4 DMZ.

Below is where the door is, how to get the key and what we found inside.
- The door is in NuriGO West (G6), in the apartment block directly east of the westernmost gas station inside NuriGO Mall.

From one opening in our own run. Loot is random, so your room can roll differently, and we add every new run of this key. Values are per item, from the in-game tooltips. The carried out value is the change in the loadout value the game shows while you loot.
Most of the den is crafting parts. The server blades and computers are full of CPUs, Control Units, Electronic Sensors and Electronics, and the kitchen adds Chemicals. The valuable finds sit in the two MINA MS41 crates and the military bags, with a weapon manual, Nuclear Program Files and Degraded Execution Footage. Loot is random, so your den can roll differently.

Is the Coin Mining Den Key Worth It?
Yes. For a Rare key this is a lot of loot, and the den is easy to reach. It sits in an ordinary apartment block next to the westernmost gas station in NuriGO West, one stairwell up from the street. The server blades and computers fill your stash with CPUs, Control Units, Electronic Sensors and Electronics for the 3D Printer. The weapons are thin, one Common SMG in the rifle case, but the MINA crates and military bags can hold valuables like a weapon manual.
