Unfortunately, it's impossible to get the miner achievements. There used to be drop boxes in the arcade with gates where you could put minerals into stratums to make their levels. But since the battle sprites, there has been nothing but Valestone and Moonstone deposits making constant freeze, shock, and poison levels. So they removed the drop boxes, Valestone and Moonstone are still useless, and the only use for Crimsonite Darkmatter and Luminite are sprite foods. Levels are now randomly generated.
