Mining Jadium?

Now that some of the major bugs from the RH update have been patched (looking at you, crabs who refused to be captured), I'm finally getting back into Palia. I'm working on the Queen Ushindi housing line, and need to grind jadium.

It feels like wherever I go in RH, I can't find jadium! The other lands are easy to find mining nodes in caves and cliffs, but it feels like wherever I go in the RH, I only come across like, one or two nodes at a time.

Where are the best general spots for mining in RH?
