Step 1
Use Angel Comb as the landmark
Follow the Colonist Bunker 1 guide: from Angel Comb, turn southwest toward the two-light cave, then follow the black cable west to the green-lit Silver cave.
Early material route
Silver Location Route
Silver supports the first oxygen upgrade and the Wiring Kit electronics chain. Use the illustrated Colonist Bunker 1 cave route from Angel Comb, and choose a material target before making another pass.
Quick answer: collect 2 Silver for Standard Air Tank, or 3 for the tank plus one Wiring Kit. Follow Angel Comb → southwest two-light cave → west black cable → green-lit Silver cave. Use the route guide for pictures and oxygen stops.

Early Silver route plan
Step 2
Choose a material target
Collect 2 Silver for Standard Air Tank or 3 Silver for that tank plus one Wiring Kit. The kit also needs 1 Copper Wire, made from 2 Copper.
Step 3
Recognize the green-lit cave
Follow the black cable west around 270 degrees, enter the next cave, then look upward for the green plant glow. Keep the entrance in view while descending to collect Silver.
Step 4
Return with oxygen in reserve
Use the nearby oxygen point before another pass. If the first two Silver complete your tank budget, return to craft it; entering the deeper red-hatch bunker is a separate objective.
Why Silver matters
Make the Standard Air Tank first when oxygen limits your trips, then set aside Silver for the Wiring Kits used by your next tools. Each kit is consumed by its recipe: one finished kit cannot cover several electronics projects.
Standard Air Tank
Reserve 2 Silver, 2 Titanium, and 1 Rubber for the first tank.
Wiring Kit
Reserve 1 Silver plus 2 raw Copper. Turn the Copper into one Copper Wire before making the kit.
Tank plus a kit
A Standard Air Tank and one Wiring Kit together need 3 Silver, alongside their other materials.
Three electronics goals
Repair Tool, System Chip, and Advanced Wiring Kit each consume a separate Wiring Kit. Their kits require 3 Silver and 6 Copper in total; the other ingredients are additional.
Depth discipline
If the Silver route forces a risky deep dive on starter oxygen, stabilize oxygen or vehicle routing first.
Patch changes
Hotfix 2 added more Silver resource areas to the early-game region.

Questions people ask
Where do I find Silver in Subnautica 2?
For the first oxygen upgrade, use the Colonist Bunker 1 Silver route from Angel Comb to the green-lit cave. It is a focused early trip for two Silver and the Standard Air Tank craft.
Did Hotfix 2 change Silver in Subnautica 2?
Yes. The official Hotfix 2 note says more Silver resource areas were added in the early-game region. The Colonist Bunker 1 cave remains a useful landmark-based trip for the first tank and Wiring Kits.
What is Silver used for?
Standard Air Tank uses 2 Silver. Wiring Kit uses 1 Silver and 1 Copper Wire, and that kit is consumed separately by Repair Tool, System Chip, or Advanced Wiring Kit. Reserve 3 Silver for the first tank plus one kit.
Do I have to enter Colonist Bunker 1 to collect Silver?
No. Collect Silver in the green-lit cave before the deeper bunker passage. The red hatch and interior scans are a separate extension; return to craft your tank if oxygen is tight.
