History & Geology
The Long Road to Gold Point, Nevada
September 2013 by Bill Rich
Apart from the hard rock mines, there are abundant gold-bearing placers, especially in the areas in and around Oriental Wash.
Mining Pegmatite Deposits
With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.

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.Researching Mineralized Areas
There are a load of ways to do research, and I’m going to talk about how I do it—maybe you’ll get some ideas that will work for you, too.
Understanding and Prospecting Benches
The most obvious benches are usually near the valley floor, but they can be thousands of feet above the valley floor. Since benches were made by streams, they can contain placer deposits.
The Significance of Nuggets in Placers
Chances are better that both types of gold did not come from the same source. Let's look at the probable conditions to cause two types of gold in a placer.
Confluence Placers
Confluences of placer streams are well known as concentration sites for heavy minerals. The basic reason is that...
