Icecore Prospect

Recover gold from three central veins. Tunnel inward, refine exposed ore with a cross-shaped blast, then collect it before another blast burns it. Only two charges. Select a tool and target, then Apply. Hand tools require edge access or an adjacent empty cell. Scraper: ice→rock. Drill: rock→ore. Grabber takes ore or gold, but only vein gold counts toward the contract. Blast advances every material in its cross, turning vein ore into gold and destroying existing gold. Undo recovers tools and destroyed samples. No timer.
