Ask the Experts: VMS ore
August 2012 by Chris Ralph
Q: Are there any mills that handle VMS ore?Gold in The Silver Crown District, Wyoming
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 of Plumas County
Plumas County has a rich heritage of gold mining, much of it from placer deposits that can still be searched and panned today. Being at the far northern end of California’s famed Mother Lode, it is quite often overlooked by those searching for gold today—really a well-kept secret after all of these years!

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.
The Verde Copper-Gold-Silver-Zinc District, Jerome, Arizona
When I was a student in the College of Mines at the University of Utah, the Verde district was used as an exploration model for “submarine volcanogenic massive sulfide deposits.” So I looked forward to visiting this district and the town of Jerome in central Arizona in the spring of 2012.
Yesterday's Gold—Today's Mine
It would seem that we are often indeed destined to repeat history. In terms of gold discovery, even with all the advancements that have been made over the years, it seems we are once again on the cusp of returning to the 1800s world of gold mining. Even as you read this, a new gold rush is taking place in a sleepy little town in South Carolina.
