Lithium spawns in Mushroom forest.

Rubies spawn in Bulb Zone, next to the hot water vent thingies. Watch out for bonesharks.

It totally depends on the sort of resource you are after. They are spread out all over. Usually specific resorces are found in certain places while others are found throughout.

If you want to find everything yourself, without looking anything up, you'll want to find the fragments to build basic base pieces and a scanner room.

The scanner room checks for a resource you select within a range.

Build a scanner room in multiple biomes, and you'll start to see where all of the resources are throughout the world.

Besides that -- scan things and check your PDA. It'll tell you more about any resources it can make since some things require "samples."

Build a scanner room and a HUD chip, let it do your job

Go. Deeper.

Silver from sandstone and mobile vehicle bay fragments in the kelp forest I think

Try here and here. The wiki may contain spoilers, but most of the time they are marked and hidden until you click on the 'show' button.

I'd love to use this in my world but I'm struggling a bit with deciphering the info in the spreadsheet? Am I dense or what

I used same trick, but with picture of biome map .. I used to have it in cyclops's helm so I could look at it while navigating 😄

does this work for switch?

Very neat trick.

I plant vine in front of my moonpool entrance over 50m to make like a entry vector

Cyclops fragments - Mushroom forest (signal for emissary will guide you there) Cyclops engine - near the Aurora engines/Underwater Islands wreck outside of it on the ground.  Ruby near Officer Keen lifepod and in general in that biome plenty Magnetite - Yellyshroom cave (Ozzies lifepod gives you a clue)  Ion Cubes generally in Alien facilities  Crystalline Sulfur in Lost River (green brine pools) 

Use this interactive map it’ll pretty much give you everything you need https://subnauticamap.io

Magnetite is in the jellyshroom caves. The place with the purple mushrooms. >!Its where Degasi Base 2 is. Or theres an entrance near lifepod 17.!<

Cyclops bridge and hull fragments are best found in the mushroom forest >!northwest or northeast fo your spawn approximately.!< cyclops engine fragments are harder. >!I recommend the underwater islands wreck just west of the Island where the sunbeam came or rhe crag field far behind the aurora with the spikes where all the bonesharks are.!<

If you want to avoid spoilers, get yourself a scanner room. Build it near Lifepod 17. Use the remote cameras to find your first magnetite, then construct the HUD chip. A scanner room, solar panel, and hatch don’t take up a lot of inventory space so you can deconstruct it and take it from biome to biome to find everything you need. 

Scanner room plus hud upgrade. Pop a couple of those suckers around the map and you’ll have a ton of whatever you’re looking for in no time. I have one in the safe shallows and another in the north west mushroom forest and it took me like 5 min to gather the resources for a cyclops.

Make circuits around the Aurora with a Cyclops to gather tons of metal salvage quickly and easily*.

Reapers make it not easily. Make 3-4 scanners along your route to track them and avoid them. Or kill them, if you're one of those people.

Unless you have some strong desire to do it “naturally” there is nothing wrong with using creative mode to scratch the itch of making a huge base. You already beat the game after all. You’d really save yourself a lot of hassle, and huge projects can cause burnout.

Go around the lost river with a drill/grapple prawn

When I am usually doing a big resource grab, I have found success going along the border area of the dunes/shroom first in the west. I take all the vehicles, use the seamoth to find nodes, prawn to mine, cyclops to store. You’ll find lots of titanium and crystal, your most used base building mats and some of the rest as well

Head to Lifepod 19. Along the black walls in that entire area you'll find a TON of ruby. It goes down to 300 meters.

Only place I can think of is the place where officer keen's lifepod is

Sparse reef, it is right under the big floating island

First of all make a Seamoth depth module if you haven’t yet, then make a depth module MK2. For that you need magnetite which is found in abundance in the Jellyshroom caves (big glowing mushrooms), then if you want rubies, the first place off the top of my head would be the grand reef (go in the direction of the big cloud to the right of the Aurora)

WHOLE COMMENT IS SPOILERS BUT THIS IS A SPOILERS THREAD SO I SHOULD BE OKAY RIGHT?

Mushroom cave for gold, lithium, and magnetite. Grassy plains (red grass) for quartz, sandstone. Sea traders path for shale out cropping. Shallows and the stalkers place (the green one) for limestone.

Personally, I love putting down a scanner base right by lifepod 17, near the entrance of the mushroom caves. Plenty of sandstone, limestone, metal salvage, quartz, and the goodies in the cave, of course.

I've been looking for a reason to write this down somewhere. Ignoring the stuff that's obvious, ubiquitous, or late-game (you'll find it when you get there), the first good place to find certain items is:

• Lithium is in >!the Mushroom Forests!<
• Magnetite is in >!the Jellyshroom Caves!<
• Ruby tends to be >!near thermal vents!<
• And there's a lot of good stuff in >!the caves on the QEP island.!<

If you forget what outcrops hide which resources, check your PDA.

Scanner Rooms are under-appreciated. Get yourself the HUD chip ASAP, priority number one as soon as you find your first Magnetite.

Also, grab a sample of every single plant the game will let you pick up and build a series of growbeds in and around your main seabase for them. With the possible exception of the Tiger Plant.

Sea Treaders Path have infinite shale deposits. They appear after the sea treaders take a step. You’ll never run out of gold, lithium, and diamonds.

Over the Jellyshroom cave, every basic ressource in a 100m radius

Behind the Aurora!

Not joking, when I first played I couldn’t find sulfur till a grav trap pulled it for me

This is useful when you can’t really see where resources are. It’s how I got first bits of lithium and magnetite. It’s also somewhat better than chasing fish down.

Wow, I might actually make a grav-trap now

also really useful with sea trader leviathans

Nice! I never thought of this :)

Underwater Islands has tons of large gold deposits all around it

Wouldn't >! sea treader's path!< be best for gold, lithium and diamonds?
