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.
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...
Nevada's Lithium Boom
When prospecting for lithium, after confirming for macro attributes through research and field work, including examination of surface geology, the main tool is an accurate lithium assay.
Gold and Silver Deposits of Bodie, California
Bodie, California, in its heyday, was once rumored to be one of the roughest and most lawless towns in the American West.
Placer Mining At Chititu Creek, Alaska
There is reason to believe these stream valleys are still rich with gold, silver and copper.
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.
The Golden Streams of Butte County, California
Even though these were some of the earliest placer deposits to be worked, there is still plenty of gold left today—it just takes more work to recover. Knowing about the old locations where gold has been found is the first step to success.
