Need more of gold and aetherium

[Humble]

I'm in final angra Mainyu Bridge camp, but where and how do I find or collect more of gold and aetherium for crafting stuff for best stuff for everyone before final quest/areas battle?

If you haven't already cleared the Arena, you can also beat up on repeatable missions. It will always yield 1 aetherium at the end, and maybe you'll get some lucky drops.

Hmmm, I go revisited map Aetherial Manifold again, and do find few more of those thing, but problem is I'm done with that map where there is dragon standing with huge green cheat, it's where first place to enter other place in main quest, but this time, there is no door or anything, so I'm unable to get out of map or unable to return to the world map, camp, not sure how I got out of here?

There's an exit mission option in game settings, or you can click exit on the menu bar to leave repeatable missions.

Check in the Settings, in the menu, you'll see an "Exit current mission" option.
