After doing the exotic ore mining mission (3 times) i have never been able to find an exotic ore deposit in a cave in any other mission.
Definitly 10 to 15 missions and 100+ caves.
Is that normal.
Do they only spawn in specific missions or in all of them???

Don't think they spawn on Outpost type missions.

They are random. I can normally find them without looking too hard...I believe that sometimes they may spawn in bad spots you can't access.

Yeah it's totally random. I don't typically go out of my way to look for them. If I pass a cave I'll usually check it out, but I don't scower the map for them.

I always forget that they are a thing and am pleasantly surprised when i find a few. Last time i found them in 5 caves that were close to eachother. 3 days ago just one cave...

I wasn't sure if they spawned more than one per map.

So is it an RNG chance per cave then? Must be RNG chance per node if you had multiple in one cave and it wasn't an exotic mission or something.

Most likely. 5 caves is the most we found so far. The caves also offer different types of ores every time too so it's looking like an RNG thing.

Ok so i have realy bad luck all the time.
I'm not really looking for it either. I just noticed that in the many days and many caves I have never found an ore deposit.
Friends of mine told me that they occasionally find some, just like you.
