Miner

A miner is someone who works in a mine. Mines can afford prospectors any number of riches ranging from conventional minerals such as gold and copper to more fictional fare like gulanite. On the Syfy original series Defiance, the character of Rafe McCawley was the owner of the McCawley Mines, which, in addition to containing lodes of gulanite, was also where an ancient alien spacecraft had laid dormant and buried.
