Miner

The man who moves a mountain begins by carrying away small stones.

Description

 * I mine useful or valuable ores and refine them into minerals.
 * I search asteroid belts for useful or valuable ores.
 * When I find the right asteroid type I mine the ore.
 * I return to a station or starbase with my ore.
 * My ore can be refined into minerals I sell on the market.
 * If the ore is in demand I also sell it directly without refining.
