Horace Austin Warner Tabor (November 26, 1830 - April 10, 1899), also known as Silver Dollar Tabor and The Bonanza King of Leadville, was an American prospector, businessman, and politician born in Holland, Vermont to Cornelius Dunham Tabor and Sarah Ferrin.

The Colorado Gold Rush was the boom in the prospecting and mining of gold in present-day Colorado in the United States that began in 1859 (when the land was still in the Kansas Territory) and lasted throughout the early 1860s.

While this is not exactly mining history, I thought that this event was an important enough event in the general history of the West that it deserved a section on this site. San Francisco was the center of finance and industry for many of the western mining frontiers, so this section is actually appropriate to the theme of this site.

The Colorado Silver Boom was a dramatic expansionist period of silver mining activity in the U.S. state of Colorado in the late 19th century.

Deep within the mountains of the panhandle of Idaho is a valley that white people named Silver. This valley is the heart of what became known as the Coeur d'Alene Mining District.
