Quartzburg, Idaho

[1] The discovery of gold, silver, and other valuable natural resources throughout the Idaho territory beginning in the 1860s, as well as the completion of the Transcontinental Railroad in 1869, brought many new people to the area, including Chinese laborers who came to work the mines.

Where two rivers, creeks, or streams divided, prospectors would each and follow the richer one in their search for the source of the gold also known as the mother lode.

Annie Lee was a legendary Idaho city woman who like Polly Bemis, escaped enslavement as a prostitute.

[4] The story of Polly Bemis, who helped settle the Idaho territory, became the basis for the novel and fictionalized 1991 film A Thousand Pieces of Gold, which was set in California.

When silica-rich solutions penetrate cooler rocks, the silica will precipitate as quartz in fissures, forming thin white seams as well as large veins which may extend over many kilometers.

Phyllites and schists often contain thin lenticular or regular veins of so-called "segregation quartz" [8] that run parallel to the bedding and are the result of local transport of silica during metamorphosis.

Orogenic gold deposits (Böhlke, 1982) dominantly form in metamorphic rocks in the mid- to shallow crust (5–15 km depth), at or above the brittle-ductile transition, in compressional settings that facilitate transfer of hot gold-bearing fluids from deeper levels.

This rapid rise takes the fluids out of equilibrium with their surrounding rocks, promoting destabilization of the gold-carrying hydrosulfide complexes [Au(HS)2− and AuHS].

- East of Idaho City a road crosses the divide between the drainage basins of Moore Creek and North Fork of Boise River and leads to the Edna and Banner silver mines.

The company employed upwards of 300 men who constructed a wooden dam across the Boise River to provide a log pond and an electrical plant for the sawmill.
