Gold From Cemented Gravels
November 2011 by Chris Ralph
The truth is that cemented gravels are really not all that complex. There is no mystery of how gold grew there or somehow wormed its way into these solid gravels.Additional articles that might interest you...
The Pedro Gold Dredge
October 2014
The decision was made to move the dredge intact, a massive undertaking indeed. The goal was to move it only one mile to the Busby’s Chicken Gold Camp, but what a mile that was to be.

The Giant King Mine

Most gold-bearing veins in this region are controlled by fractures associated with the Melones Fault, a late Cretaceous structure that is 108 to 127 million years old.

Calcite and Limestone
February 2017
The other distinguishing feature of calcite has to do with its chemistry. Geologists sometimes take a small bottle of dilute hydrochloric acid out into the field with them because calcite reacts with acids to make a bubbly foam.

The Long Road to Gold Point, Nevada

Electrum: Gold and Silver Together
January 2016
...if you are out prospecting and find something that looks very much like a nugget but has an odd greenish-gray cast to it, don’t be too quick to simply toss it aside as junk.

Nevada's Silver City Gold District—Part I
March 2016
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.

Prospecting for lithium deposits can take a number of different directions, because this metal can be extracted from a variety of geologically differnet sources.
