How did mining lead to the establishment of new towns in the west?

Mining settlements sometimes developed into permanent towns and cities.

Explanation:

Beginning with the California Gold Rush of 1849, several other mining areas were discovered in the West.

These new boomtowns provided the crucial material for the eastern Industrial Revolution: gold, silver, zinc, copper, and lead.

Each mining area needed a town. Although most of them would disappear after the mines were emptied, leaving behind ghost towns, some of them prospered into big cities.
