Mini Miner addresses a common inefficiency in modded Minecraft: the “giant hole” problem. Traditional quarry solutions often require massive multi-block structures that destroy landscapes and lower frame rates. This project introduces a compact, single-block solution designed to automate resource gathering while maintaining the aesthetic integrity of the player’s base.

Compact Architecture: Unlike traditional 64×64 quarries, the Mini Miner functions as a standalone, single-block entity, allowing for discreet placement within existing builds.

Automated Resource Extraction: The unit automatically mines resources from the chunk it is placed in without physically breaking the blocks in the world, preserving the terrain.
