This page isn't as much a guide as it is a map for all the different Orichalcum Nodes I have found in the game. There will always be nodes not listed here since they are always changing but consider this a constant source of new information for when I find a node that isn't on this page. And a source of information of known locations or areas you could hunt to find Orichalcum Spawn Locations. I will update it as much as possible but for now, here you go!
It is also important to remember certain Orichalcum nodes have a 24/7 respawn time and other ones seem to be up at the same time every other node respawns.
If you follow the links below you'll find all of the Orichalcum Spawn Locations as well as Ancient Wood Spawn locations listed on big map pictures instead of broken down into their own individual pictures. It may be easier to understand for some people.
Cursed Shore - Orichalcum Hotspot Desmina's Hallow
This location deserves to be completely singled out because at almost all times there is an orichalcum node here. I have found that no matter how many times the nodes change Desmina's Hallows always has at least one but typically two active Orichalcum Nodes present. If you want to find some easy Orichalcum without too much running around aimlessly, come here!

Easiest to gather Orichalcum Node probably in the game

Malchor's Leap - Blighted Arch Orichalcum
This is one of the hardest Orichalcum nodes to get too. It is surrounded by Veteran mobs so if you plan to get it you should bring a friend. The closest waypoint is Blighted Arch Waypoint just to the south.
