Fired up a few more along the way, learned a few nice new pieces of detail.
#1: Some forms of "crap rock" (I'm looking at you Orthoclase). Are not counted in the shallow/deep metals even though they're part of the stone minerals raw. Good to know that. This may only be true for .21 and not earlier.
#2: Raw Adamantine is not a deep metal.
At about 6k my shallow/deep metal 2 biome site didn't have any metal in some situations, but it did have Orthoclase.
I unfortunately had to skip 4.5K 24K, and36K since a dwarf civ was genned right on top of it. They needed to move. Regenned the worlds 5 times with no luck.

And this one I was hoping would be particularly interesting since it's past the theoretical wrap-around point. Unfortunately it's not. Most of the map is lit up as shallow/deep metal just like 48000 but my location, I've been recycling over and over is...utter crap.

It'd require more testing to delve further into this, but at least one thing seems to be conclusive now. Stuff isn't getting flagged as shallow/deep metal in .21 if you can't smelt it. Which is a general relief compared to the .19 situation where people were reporting cobaltite or something for a metal.
A little more learned and a little fun from it.
