Ores

Ores are collected by mining clones from the back of your base. Ores are usually in big rocks from the hills in the map and only some ores can only be obtained by certain pickaxes and a certain limit of how many of the certain ore you can keep. To expand your ore limit, buy the ore storage from Build Mode.
