The derrick is a building intended for the extraction of raw materials from the earth. If erected in a location where titanium or uranium are present in the subsoil, it will extract chunks of ore at a regular rate. If an object (most commonly another ore) is already present in the drop zone when it finishes digging, the derrick's functions will pause and it will hold the ore until the offending item is removed, after which it will drop its ore and resume drilling. In order to determine the best site on which to erect a derrick, a sniffer should be used to prospect the subsoil. The marks it lays down provide information about the specifics of what the derrick will be able to extract; a red cross indicates the presence of titanium in the subsoil, while a yellow circle with a black radiation symbol represents a uranium deposit.
