WSGS Releases New Geologic Maps
December 2011 by Scott Harn
The Wyoming State Geological Survey announced ten new geologic maps have been completed and are now available.Critical Minerals: Gold
A few quick calculations show that approximately 11 tons of gold are lost each year just in the manufacture of new cell phones.
Round Mountain, Nevada
There are a number of veins in the disseminated mineralization, but the principle ones on Round Mountain are known as the Los Gazabo and the Keane.
Critical Minerals: Titanium—Part II
There are both hard rock and beach sand types of titanium deposits, but the hard rock deposits need to be at least 10 percent titanium while the beach sands often are economic with only two or three percent titanium.
The Silver Islet Mountains of Utah
I set up my dry washer on the north side of the cut and sampled the bed rock and dumps around me. As I was only sampling, I ran for 20-30 minutes, shoveling from a variety of areas.
It Pays to Know Your Bedrock
On our last trip, we brought ropes and went down the first waterfall forty vertical feet, only to be confronted by a second, sixty-foot-high, overhanging waterfall that emptied into a slot canyon.
California's Mother Lode Quartz Veins
The actions of the hot, ore-bearing solutions are not limited only to the deposition of material within the walls of the fissures.
The Pedro Gold Dredge
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.
