One of the most common problems for new players in Subnautica 2 Early Access is finding Silver Ore early enough to craft the Air Tank before the limited oxygen supply starts causing real problems. The starting oxygen supply runs out surprisingly quickly — especially once you begin exploring caves, tunnels, wreckage, and any resource areas that sit at meaningful depth. Crafting the Air Tank is one of the most important early upgrades in the game, and getting there requires Silver. This guide shows you where to look, what to expect, and how to make the hunt efficient from the very start of your playthrough.
Why the Air Tank Matters So Much Early On
In Subnautica 2, your starting oxygen capacity is deliberately limited. This is an intentional design choice that keeps the early game feeling tense and encourages careful, shallow exploration before players are ready for deeper water. However, that limited oxygen also means that every dive is on a tight clock. You swim down, gather what you can, and return to the surface or the escape pod before you run out of air.
The Air Tank changes this dynamic significantly. With an upgraded oxygen supply, your dives last longer, your exploration radius expands, and gathering resources from slightly deeper areas becomes much more practical. You can spend more time scanning blueprints, collecting materials from caves and outcrops, and investigating points of interest without constantly needing to surface.
Almost everything that opens up the early-to-mid game in Subnautica 2 benefits from having the Air Tank. It is one of the first meaningful progression milestones and Silver Ore is the key material that makes it possible.
Where to Find Silver Near the Starting Area
Silver Ore in Subnautica 2 is found in cave environments near the starting region. Unlike surface outcrops or shallow-water deposits, Silver tends to spawn in areas that require a short dive — enough to put a small amount of pressure on your oxygen supply but not so deep that it is inaccessible before you have any upgrades.
The key is knowing what type of geological environment to look for. Silver in Subnautica 2 appears in cave systems and rocky outcrops in areas with specific terrain features. Rather than searching open water, look for cave entrances at depth — often signalled by darker patches on the seafloor, rocky formations, and the visual style that distinguishes underground resource areas from open biome terrain.
Hotfix 2 added more Silver resource areas to the early-game region specifically in response to player feedback that Silver was too scarce for new players. This means that after Hotfix 2, Silver should be more accessible near the starting zone than it was in the first days of Early Access. If you played at launch and struggled to find Silver, the situation should be meaningfully better in the patched version.
What Equipment to Bring
Before heading into cave systems to hunt for Silver, you should have your core early tools prepared. The Scanner is essential — not just for scanning Silver and identifying it reliably, but also for scanning any other blueprints and resources you encounter during the same dive. Every cave run is an opportunity to gather multiple types of useful data, and the Scanner makes it possible to do that efficiently.
The Survival Multi-Tool is your primary means of extracting ore and resources. Without it, you cannot gather the Silver even when you find it. Make sure the Multi-Tool is charged and ready before you dive into a resource cave.
Having a good supply of oxygen before going into caves is the other critical factor. Do not start a Silver-hunting dive if your oxygen is already low from a previous run. The cave environment limits your ability to quickly surface, so beginning every cave dive with full oxygen is a basic safety rule that will save you from a lot of unnecessary deaths in the early game.
How to Spot Cave Entrances
Cave entrances in Subnautica 2 are often easy to miss when you are focused on looking for ore deposits in open water. The key visual signals to watch for are darker patches in the seafloor, tunnel-like openings in rocky formations, and areas where the terrain shifts from sandy or biome-floor surfaces to harder rock structures.
The depth at which Silver caves appear in the early game is manageable without the Air Tank, but you will need to be efficient. Plan your route through the cave before committing, know roughly where you entered, and turn back toward the surface or exit before your oxygen reaches the danger zone — not when it is already critical. Subnautica 2 gives you audio and visual warnings as oxygen depletes, and learning to respond to those warnings before they become emergencies is a survival skill worth developing in the first hours of the game.
Crafting the Air Tank
Once you have gathered sufficient Silver Ore, return to your escape pod and the Fabricator to craft the Air Tank. The Air Tank is crafted using Silver Ore combined with other early-game materials. The exact recipe is visible in the Fabricator interface once you have scanned the relevant blueprint or progressed far enough in the crafting tree.
Equipping the Air Tank immediately expands your oxygen capacity and changes how the early-to-mid game feels. Dives that were previously risky become manageable. Resource areas that were borderline inaccessible become reachable with reasonable confidence. The Air Tank is not a luxury in Subnautica 2 — it is effectively a prerequisite for comfortable progression beyond the very first hours of the game.
Tips for Efficient Silver Hunting
A few principles will make Silver hunting significantly more efficient in the early game. First, use the Ping system to mark any cave entrances you find but have not fully explored yet. Coming back to a known cave location is much faster than finding a new one from scratch on every dive. Second, gather Silver whenever you encounter it, even if you are not specifically hunting for it at that moment. Silver deposits respawn on a longer cycle, so taking what is available when you see it prevents wasted future dives.
Third, combine your Silver-hunting dives with scanning runs. If you are diving into a cave looking for Silver, bring the Scanner and scan everything else you see while you are down there. Blueprints, creatures, and other resources scanned during Silver runs make each dive more productive overall and accelerate your crafting progress faster than single-purpose dives.
