Insane deepslate emerald generation in meadow biome (triple vein and 3 more within 70 blocks)

I was just mining in a meadow biome on my aternos server and found this. I counted 6 deepslate Emeralds total in a really small area. one spot even has triple vein in the same chunk. I also found 8 deepslate coal ore nearby in one vein.

Explaining the creative mode: I found this while mining on my aternos survival server first. I was so shocked that I opened a new world with the same seed in creative just to get a clear screenshot of the whole vein (Seed and coords are in the description if you want to verify it)
