Deepslate coal and emerald nearby each other

I started a minecraft game under the seed 2026 for new years for fun in survival mode, and its actually a decently beautiful seed and has a cool cherry blossom mountain pit at -500, -500 ish. But while mining, I found deepslate coal and deepslate emerald in the same general cave no xray, cheating, or mods at -473, 1, -481 for the emerald and -545, 2, -515
