A district in which gold is found as a mineral:the Klondike goldfields...
A map of Victoria in 1869 showed most of the colony, except for the Western District and the central goldfields, still under forest cover.
The New Zealand Minerals Industry Association estimates there is $30 billion worth of gold in the Hauraki goldfields but most is under Conservation Department land which can not be mined.
It was built to satisfy the demand for an improved route to the goldfields on the West Coast.
