Reno's 1872 Time Capsule Includes Gold Rush Lore
June 2019 by Associated Press
The Reno Masonic Lodge was built along the railroad tracks back when Ulysses S. Grant was president and shortly after the Comstock Lode of gold and silver was struck in Virginia City.
Gold of Plumas County
Plumas County has a rich heritage of gold mining, much of it from placer deposits that can still be searched and panned today. Being at the far northern end of California’s famed Mother Lode, it is quite often overlooked by those searching for gold today—really a well-kept secret after all of these years!
Gangue Minerals - What Do They Tell Us?
There are a large number of different kinds of gangue minerals, and each of them has its own tale to contribute to the story of the chemistry and geology of a deposit.
Preserving the True History of the Ivanhoe
My partner had the contacts and it wasn’t long before we had an agreement in place and the company had a geologist on site. I recall a time when he was getting the lay of the land, so to speak, and he broke off a rock sample and inspected it with his magnifier.
Gold, Quartz & Chalcedony—Part II
The specific gravity of chalcedony is 2.58 to 2.64. This is slightly lower than coarsely crystalline quartz because of slight porosity in chalcedony. Being so light, it will easily wash out of a gold pan.
Gold Deposits of Montana
Historically, Montana has been an important gold producer, in terms of both lodes and placers, and it still produces gold for the prospector today.
Prospecting for Silver Deposits
In some ways, silver is the forgotten precious metal because it straddles both the world of precious metals and jewelry, while having many important industrial applications like a base metal. The price of silver reflects both the precious metal investment demand as well as the industrial demand.
Nevada's Silver City Gold District—Part I
The name Silver City is quite ironic as it doesn’t really fit the area’s metal production. The area encompassing the Silver City district is a great, stand-alone gold district, where the production value of gold has been much more than that of silver. Since the initial discovery of gold-bearing veins in the mid-1850s, the area has been a center of continuous small and large-scale gold production.
