Every ore patch on every surface is infinite. Patches show a yield percent instead of an ore count — like oil wells — frozen forever at each patch's natural richness. And the percent is the patch's mining speed: a 4,000% mega-patch runs its drills 40x faster, forever. A pure data-stage tweak: no scripting, no per-tick cost, no save bloat. Vanilla ores, Space Age, and modded resources all covered automatically. Dig forever.
