History & Geology
The Golden Streams of Butte County, California
May 2011 by Frank Lorey III
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.Why Haven't They Mined This Claim?
Improvements in mining equipment and techniques, along with a higher gold price, make many mining properties profitable today that may not have been in the past.
Unique Rare Earth Mine in Texas
Exploration for and prospecting in search of similar deposits should focus on rhyolite bodies located in fluorite-bearing areas.
Glaciers and Placer Gold Deposits
It also happens sometimes that glaciers will bury valuable placer deposits. This occurs when the glacier goes over the top of an existing placer deposit.
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 Rare Earth Elements in New Mexico
We import nearly all of our REEs from China, so it’s critical that we find and continue to develop domestic resources of these elements.
California: The Land of Big Nuggets—Part II
There are a number of Tertiary river channels in the area, most of which trend south-southwest. They tend to be steep, narrow, and rich with coarse gold.
Gold Depositiion and Gradients of Placer Streams—Part II
The steeper the gradient is, the more potential erosive power to move gold and other bedload sediments, and the more power to remove obstacles to flow.
