Find some compass. A good source of iridium.

引用自 Carly：

I've been in the mine for 15-30 minutes and i still cant find any.

Fishing is also a good source

Thanks i didnt know i can get it like that

Scrap AP shells or from quest for copper coils

Edit: And fishing

You also get Iridium bar in airdrops but its going to take 3 in-game days till the heil come by and drop the crate

To sum it up in one post:

- you get iridium by scraping: AP-Shell, compass and spark-plug
- get it from fishing
- from airdrops
- the architect has a barter option after some progress in his questline, where you can exchange one big copper coil for 3 iridium "parts" (yes, it is repeatable)
