Kyanite is one of the more elusive mineral deposits in Subnautica, prized for its distinct blue hue and its role in crafting advanced components. Unlike common resources such as copper or titanium, kyanite does not form exposed veins on the seabed, requiring a more deliberate approach to locate. This guide details the specific environments, tools, and scanning techniques necessary to reliably find and harvest kyanite.
Geographic Distribution and Biome Specifics
The primary factor in finding kyanite is understanding its strict depth and biome requirements. This resource exclusively generates in the Lost River and the deeper reaches of the Grand Reef, specifically within the Kyanite Biome. You will not find it in the shallower kelp forests or the sparse grass plains, so wasting time scanning the wrong areas is counterproductive. The mineral appears as clusters of light blue crystals against the dark rock, making visual identification straightforward once you are in the correct zone.
Utilizing the Habitat Scanner Effectively
To avoid aimless wandering, the Habitat Scanner is your most reliable tool for confirming the presence of kyanite in your immediate vicinity. Before deploying the scanner, check your navigation chart to ensure you are hovering over the Lost River or a deep section of the Grand Reef. When the scanner reveals the Kyanite Biome icon, you can be confident that deposits are nearby. Use the scanner in a slow, sweeping motion just above the terrain to pinpoint the exact location of the resource nodes without breaking the surface.
Scanning Tips and Range
The scanner provides a radius of detection, so it is not necessary to locate the exact node the first time. If the icon appears faint, move systematically through the biome until the signal strengthens. Remember that kyanite only appears below a certain depth threshold, so ensure your vehicle or your position is sufficiently submerged. Floating on the surface will yield no results, as the resource is buried beneath the seabed.
Extraction and Resource Management
Once the resource node is identified, extraction requires a specific tool to avoid wasting energy. A Survival Knife or a Thermal Drill is necessary to harvest the kyanite; attempting to mine it with a standard laser cutter will fail. The node yields three Kyanite per harvest, which is a relatively low drop compared to other minerals, necessitating multiple trips. Players should prioritize refining this resource only when they have a specific build queue that requires the Blue Capsule or the Ion Cube.
Efficient Route Planning
Because kyanite is found in a dangerous region of the map, preparation is essential for survival. The Lost River is home to aggressive fauna such as the Reaper Leviathan, and the Grand Reef features Stalkers that can disorient your view. Equip your vehicle with high-grade sonar and lights to navigate the pitch-black waters safely. It is often more efficient to collect a sufficient quantity in a single dive rather than making repeated short trips, conserving both oxygen and battery power.
Alternative Methods and Common Pitfalls
Some players experiment with using Propulsion Cannon fragments to move surface deposits, but this is unreliable as the resource often fails to register in the inventory when broken. The definitive method is always to locate the correct biome and extract it properly. A common pitfall is confusing the visual texture of kyanite with other blue-hued resources like quartz; however, kyanite crystals have a more vibrant, saturated blue and a distinct crystalline shape that sets it apart.
