Stone Hatch: rock feed, coal output, and mineral planning
Stone Hatch-style critters focus more heavily on rock and mineral conversion. They fit bases with large mineral stockpiles, but only when the player knows which resources are truly expendable.
Resource role
The purpose is to turn selected rock materials into power-chain support. It will not solve every power problem, but it can extend the usefulness of coal-based systems.
Feed selection
Do not treat every rock as surplus. Granite, sandstone, ores, and other minerals may be needed for construction, decor, insulation, or refining. Confirm short-term building plans before feeding them away.
Layout advice
Place the ranch near mineral storage and coal output. With shipping, separate feed input from product output to avoid accidental hauling loops.
Best timing
Mid-game is usually best. Early on, materials are too scarce to sacrifice casually. Later, coal may matter less once stronger power systems exist.
