A mining/transport strategy game

This is a business game in which each player owns a mining company. The aim is to mine ore and transport it to the coast and then overseas where it is sold as exports. It is by the effective use of three types of transport: lorries, barges and ships, that players maximise profits. 

The struggle to expand business and achieve maximum exports but keep ahead of rivals, produces one of the most compelling business games ever invented (back in the 70's)
