Finding Atacamite in Subnautica 2 might not seem like a priority during your first few hours on the planet, but this mineral is essential for mid-to-late game progression. It serves as a primary ingredient for crafting Mangalloy Ingots, which are required to build invaluable Metal Farms once you unlock the necessary blueprints.
Beyond base building, you will eventually need ten Mangalloy Ingots specifically to repair the Alien Power Plant. While materials like Celestine or Creature Enamel are often needed for immediate glass upgrades, Atacamite is a resource you can collect steadily as you venture into deeper waters.
Best Subnautica 2 Atacamite Location
To find Atacamite effectively, you need to head to deeper zones. Most deposits are located at depths exceeding 250 meters, specifically clustered around the Alien Ruins. Because of these depths, you will likely need the Tadpole Depth Module—found within the Needler nest—to reach these areas safely.
If you are looking for a high-density resource node, follow these steps:
- Locate the Alien Ruins Research Base.
- Set your compass to approximately 75 degrees (East-North-East).
- Drop off the cliffside and descend toward the alien dwellings.
- Look on the sand just to the left of the structures.
You will find large clusters of green Atacamite crystals sitting near various quartz nodes. Since you need a significant amount for the Alien Power Plant, it is best to mine as much as your inventory allows when you spot a cluster.
How to Mine Atacamite
Atacamite is easy to identify visually; look for distinct dark green columns protruding from the rock formations. Unlike some materials that require specific tools, you will use your Sonic Resonator to smash these nodes and collect the raw material.
Because this mineral is tied to major story progression and essential infrastructure like Metal Farms, don't wait until the last minute to start gathering it. Once you have the mobility to reach the 250-meter mark, make Atacamite one of your first scavenging priorities.
