Purpose 

The purpose of this activity is to give the player an introduction to the economics of mining. Each player buys "property," purchases the "mining equipment," pays for the "mining operation," and finally pays for the "reclamation." In return, the player receives money for the "ore mined." The object of the game is to develop the mine, safeguard the environment, and make as much money as possible.
