Enrichment of Gold Veins
November 2000 by Edgar B. Heylmun, PhDMost of the world's great gold mines are in secondary (supergene) enrichments in veins and stockwork, brought about by physical and chemical processes.
While women were extremely rare in the early California gold camps, their relative absence did not always guarantee their safety or protection if they happened to be of Mexican nationality. The most memorable, graphic example of this tendency took place in Downieville, seat of Sierra County located on a fork of the Yuba River.
Successful miners report that the Peshastin’s gold is unusually course and most of the recovered nuggets are small pickers. Flood gold is prevalent here and easy to find and recover on the Peshastin.
Not all of these slides and debris flows will produce results, but if you search for these while prospecting in your gold producing areas, then you can increase your odds of finding new gold.
I remember in the couple of years after that 1997 flood, prospectors around California did very well, taking ounces of gold from places that had not yielded any gold for years before that.
In part one of this two-part series on gold in Guyana, I describe artisanal mining efforts currently winning alluvial gold from small-scale placer operations located along the lower Puruni River and its tributaries.

Back in the early 1800s, there was a gold mine being dug in a mining community called Garden Valley. Garden Valley is located northeast of Sacramento, between Georgetown and Coloma. They called it Garden Valley because there were some miners who thought there might be more money in growing and selling vegetables than in mining for gold.
