History & Geology
Gold in The Silver Crown District, Wyoming
February 2015 by W. Dan Hausel
When my field assistant Jay Roberts and I entered the mine, it appeared as if someone just walked out of the mine, turned off the lights and never returned.
Gold in the San Francisco District Oatman, Mohave County, Arizona
I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
The Basics of Geophysical Exploration
In developing a mineral property or mining claims, one of the first goals is to identify and quantify valuable deposits. The classic method of doing this is by drilling holes into the ground to sample what is below the surface. The problem is that one or two holes usually are not going to tell you a whole lot...
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.

The Gold, Silver and Base Metal Mines of Eureka, Nevada
...the area around Eureka, Nevada is well mineralized and seems to have a bright potential for future production of all sorts of metals.
Calcite and Limestone
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.
Silver Peak, Nevada: A Little of Everything
Silver Peak is a small mining community in Esmeralda County in west-central Nevada, about 30 miles west of Goldfield. Although it’s fairly remote, it’s been an important mining center since the early days.
