I know that there are some very old posts about one or another invisble ressource node in the Northeast of the map but i thought i should share this hilarious screenshot of a floating caterium node :D In around 200 meters there are 2 more of these floating caterium nodes. I needed to stack 5 or more big foundations to get the miner to find the node.
Here are 2 screenshots....1 is the location and 2 is the floating and operating caterium miner.

Almost every Ressource Node in the Northeast is invisible but working. I have my Base in this desert and there is invisible iron, quartz and coal around :D
